Our Pick for the Best King Mattress is…

How We Picked the Best King-Size Mattresses

My fellow testers and I review mattresses by testing them out comprehensively in our studio. This way, we’re able to get hands-on, first-person experience from a variety of sleepers with different body types, primary sleeping positions, and overall preferences.

We then summarize our findings in easy-to-understand language to give you a clear idea of how each bed performs.

When it comes to choosing the best king mattresses, we focused on a few key categories during testing, including reliable support across the whole surface of the bed and features that benefit couples.

Methodology Image- Sleep Advisor
That’s me, testing and commenting on mattresses in our studio.

What We Want to See in a King Mattress

Support Over a Large Surface Area

Every bed on this list received at least a 4 out of 5 in the support category during testing. This category is crucial for king-size beds because of their impressive width. You want a mattress with consistent support across the entire surface, rather than one that sags or pokes in certain spots.

Couple-Friendly Features

Chances are, if you’re looking for a king-size mattress, you’ll be sharing the bed with a partner or a pet (or both!). The beds below performed well in the categories most relevant to couples, such as motion isolation, edge support, and responsiveness.

It’s important to note that some of these elements come at the cost of others. For example, a bed with great bounce—which can help facilitate intimate activities—probably won’t have the best motion isolation. So, you should decide which features matter the most to you and your partner while browsing.

Good Value

A king-size mattress is a big investment, and even the cheapest options are going to start around $1,000 minimum. The beds we’ve chosen balance high quality with affordability: most of them cost less than $2,000 for a king. Of course, when discounts are running, these prices drop lower still.

The Helix Midnight at a Glance

The Helix Midnight was built with side sleepers in mind, but it’s a great bed for anyone who wants a medium-firm feel with some initial softness. It lays three sheets of proprietary foam on top of a coil unit for a classic hybrid design. 

What’s Inside the Helix Midnight?

The Helix Midnight is 11.5 inches tall and has six layers, including its top cover.

  • Layer 1 – Cover. Made of soft, breathable fabric. Can be swapped for a GlacioTex™ Cooling Cover for an additional fee.
  • Layer 2 – Memory Plus Foam. Helix’s proprietary material that offers pressure relief and a soothing amount of give.
  • Layers 3 & 4 – Helix Response Foam. One cradles, and one is more supportive.
  • Layer 5 – Coil Unit. pocketed coils that are stronger on the long edges of the bed.
  • Layer 6 – Duradense Foam. A sturdy base.

Our Thoughts After Testing the Helix Midnight

The Midnight’s combination of cozy foams and responsive coils is tough to beat, earning it 5 out of 5 points for both support and pressure relief from me and my fellow testers. It feels welcomingly soft up top, but the coils add reassuring firmness from beneath. 

The Midnight also isolated motion much better than we expected it to. Usually, beds with springs transfer a lot of movement, but this one stayed very calm while we turned over, wiggled, and bounced. It should be great if you want to share a king-sized mattress with a restless partner. 

Its edge support, however, leaves a lot to be desired. The reinforced springs in its coil units only line the long edges of the bed, and I still felt like I was sliding off a bit when I laid close to one of those sides. It received a paltry 2 out of 5 in this category.

Customer Reviews of the Helix Midnight Mattress

The Helix Midnight rates 4.5 stars out of 5 on Helix’s website. The main negative is that reviewers tend to find it too soft for their liking and feel as though they’re sinking. But overall, users say they’re getting a great night’s sleep and some pain relief.

The Nectar at a Glance

Years after its launch, Nectar’s original memory foam bed remains one of the reigning champions of the online mattress world. Without springs (and their heftier price point), it offers a medium firmness level and a supportive foundation paired with amazing pressure relief. 

What’s Inside the Nectar?

The Nectar is 12 inches high and has a top and lower cover with three CertiPUR-US® certified foam layers in between.

  • Layer 1 – Cover. Features polyethylene fibers that should help prevent overheating.
  • Layer 2 – Gel Memory Foam (2 inches). Conforms to your silhouette and cradles sensitive pressure points.
  • Layer 3 – Transitional Foam (3 inches). A bit bouncier than the foam above, reducing the risk of a “stuck” feeling as you move around in bed.
  • Layer 4 – ActiveSupport Foam (7 inches). Serves as a firm base.

Our Thoughts After Testing the Nectar

This is an affordable option that, despite its lack of springs, finds a rare harmony between softness and support. Its cushiony surface is a special treat for achy joints even as its denser base foam pushes for proper spine alignment.

I felt lots of support, but it’s important to note that I’m an average-weight sleeper. Our heavyweight tester, Spencer, didn’t have enough to work with, especially on his stomach. 

Those eyeing a king-sized Nectar to share will also be happy to know that this bed earned a perfect 5 out of 5 for its motion isolation. Its foam layers readily trap the ripples caused by someone turning over or even getting out of bed. However, those same foam layers can hold onto heat—we gave this mattress a 2.5 out of 5 in the cooling category.

Customer Reviews of the Nectar Mattress

With thousands of reviews on Nectar’s website, the Nectar mattress has an average 4.8 out of 5 stars. One common customer complaint about the Nectar mattress is its longer-than-average break-in period, while many customers praise its excellent value and comfort once fully settled.

The Advisor Says: Its fancy quilted cover and generous foam layers make the DreamCloud Premier a slightly softer bed than the original DreamCloud. But, it still skews firm for a hybrid, so it’s best for back and side sleepers who like an initial bit of cushion followed by lots of lift.

The DreamCloud Premier at a Glance

The DreamCloud Premier is a hybrid bed that places special emphasis on its upper comfort layers. There are four foams between you and the coil unit, making this a mattress that’s well-suited for side sleeping as well as spinal alignment. 

What’s Inside the DreamCloud Premier?

The DreamCloud Premier is 13 inches high with seven total layers, including its top cover.

  • Layer 1 – Cover. Made with a soft cashmere-blend.
  • Layer 2 – Contouring Quilted Foam. Cushioning gel foam in the Euro top.
  • Layer 3 – Supportive Quilted Foam. Firmer foam in the Euro top.
  • Layer 4 – Gel Memory Foam. For cooling pressure relief.
  • Layer 5 – Transitional Foam. Foam with a slightly firmer feel to assist with spinal alignment.
  • Layer 6 – Innerspring Unit. Where pocketed coils allow for cooling airflow and the springs are reinforced along the edges.
  • Layer 7 – Base Layer. Stable foam forms the bottom layer of the bed.

Our Thoughts After Testing the DreamCloud Premier 

The DreamCloud Premier is an extra-luxurious version of one of my favorite mattresses, the DreamCloud.

It has some additional padding up top that give it a memorably plush feel, though it doesn’t lose any of the stalwart support from its innerspring unit. We gave it a 4.5 for both support and pressure relief. 

It has a balanced profile to suit side sleepers, who need both cushion and spinal alignment.

In my opinion, a king-sized version of this bed is bound to make you feel like pampered royalty regardless of your body type. 

However, its motion isolation, cooling, and edge support are nothing to write home about. All three aspects received a 3.5 out of 5 from me and the testing team. These aren’t bad scores, but if you sleep very hot or very lightly, they’re worth noting.

The WinkBed at a Glance

If you’re looking for a king-size bed that can help relieve back pain, I’d nominate the WinkBed. It’s a hybrid mattress with handcrafted touches and an especially durable innerspring unit beneath its softer foams. It has multiple firmness options, including one for heavier sleepers. 

What’s Inside the WinkBed?

The WinkBed has four firmness options you can choose from: Softer, Luxury Firm, Firmer, and Plus, the last of which is designed for heavier sleepers. Regardless of the feel you pick, it’ll stand around 13.5 inches tall.

  • Cover. A Tencel™ cover with breathable fabric derived from eucalyptus wood pulp.
  • Euro Pillow Top. Plush foam for cushioning and pressure relief.
  • Comfort and Support Layers. Additional foam layers—including a LumbarLayer™ that supports the lower back—eventually lead into the innerspring unit.
  • Coils. Different zones of innersprings offer increased pressure relief or pushback depending on their location. The coils are also reinforced along the edges to maximize your usable sleep space.

Our Thoughts After Testing the Winkbed

The WinkBed has more back-friendly features than most other beds I’ve reviewed, including zoned coils and a specialized foam “LumbarLayer™”, both of which lend the low back some enhanced support.

I’m happy to report that you can definitely feel these elements working: I was lifted in all the right places while still feeling some nice cushioning from the Euro Top. 

My fellow testers and I agreed that this is a well-rounded mattress, and it would be lovely to own in a stately king size.

It earned 4’s and 5’s across almost all performance categories, with the only exception being motion isolation. In that category, the WinkBed scored a 3 out of 5—it’s pretty average at dampening movement

Customer Reviews of the WinkBed

The Saatva Classic at a Glance

The Saatva Classic is marketed as a “luxury innerspring” mattress, and we agree with that label. Notably, it contains two coil units: an upper one with pocketed coils, and a lower one with interconnected coils. Together, they provide unflagging support inside a bed that can be customized to to suit your preferred firmness and height. 

What’s Inside the Saatva Classic?

You can order your Saatva Classic in one of two heights: 11.5 or 14.5 inches. You’ll also be able to choose between Plush Soft, Luxury Firm, and Firm models.

  • Euro Pillow Top. Soft foam dressed in an organic cotton cover, with firmer quilting in the middle to lift your lumbar spine.
  • Lumbar Crown. A strip of foam that stretches across the middle of the bed, further boosting the lumbar region.
  • First Innerspring Unit. Individually wrapped coils are stronger in the middle, where you’re likely putting the most pressure on the bed.
  • Spinal Wire. Positioned amidst the springs, this wire prevents sagging and helps keep your back properly aligned.
  • Second Innerspring Unit. Interconnected coils that permit lots of airflow and should stand up to years of use.
  • Foam Rails. Around the edges of the bed, a frame of high-density foam buttresses the sides.

Our Thoughts After Testing the Saatva Classic

I gave this mattress the winning spot in this roundup because it’s an all-around champion when it comes to support, no matter where you’re lying on the bed. 

The dual innerspring units lifted my midsection so that my spine felt aligned in all sleeping positions, including on my stomach.

The edge support is likewise phenomenal, perhaps because the sides are bolstered by thick foam (not reinforced springs like we see in most hybrids).

This is a key factor for some couples sharing a king-sized bed—it allows them to spread out without worrying about the edges dipping. 

My only concern when it comes to ordering a king-sized Classic is motion isolation. You can feel big movements made by another person from across the bed, so we awarded only 2 out of 5 points in this performance category.

Customer Reviews of the Saatva Classic

The Classic has garnered more than 3,000 online reviews on Saatva’s website, and sits at 4.8 out of 5 stars. Negative reviews tend to highlight the fact that it can take a bit of time to get your made-to-order bed delivered. But one-star reviews make up about 1% of the review pool, and most customers love the easy delivery process as well as the mattress’s effectiveness at helping with back pain.

The Brooklyn Bedding Signature Hybrid at a Glance

This hybrid comes in three distinct firmness levels, but all three should be exceptionally bouncy due to the spring unit at the base. This is a balanced bed that does the essentials well but lacks flashy bells and whistles. 

What’s Inside the Brooklyn Bedding Signature Hybrid?

The Brooklyn Bedding Signature Hybrid is 11.5 inches tall with five inner layers underneath its cover. You can order it in a Soft, Medium, or Firm feel—the firmness you choose will determine how thick each layer is.

  • Layer 1 – Quilted Top. Allows for some cushion while also preventing long-term sagging.
  • Layer 2 – Comfort Foam. Designed for both pressure relief and springy responsiveness.
  • Layer 3 – VariFlex™ Foam. Adds support and transitions into the bed’s innerspring unit.
  • Layer 4 – Innerspring Unit. Coils flex individually in fabric pockets, and reinforced springs along the sides help the edges stay strong.
  • Layer 5 – Foam Base. High-density foam acts as a long-lasting foundation.

Our Thoughts After Testing the Brooklyn Bedding Signature Hybrid 

We were getting airtime on this bed due to its powerful bounce. It received a perfect score in that category, as well as in the two most crucial ones: support and pressure relief.

Combination sleepers who shift between their sides, backs, and stomachs should appreciate how the responsive surface helps you to move instead of trapping you inside stifling layers. 

That said, this bed does not do a good job of dampening motion. A king-size version will allow you to change positions seamlessly, but anyone sharing the bed might feel your movements

The Nolah Evolution at a Glance

At 15 inches tall, a king-size Nolah Evolution cuts a striking figure in any bedroom. Its opulent construction includes seven total layers, plus an upper gusset that encourages heat to leave the mattress. With all of that material, it’s no surprise that it stands up well to the challenges of partnered sleeping.

What’s Inside the Nolah Evolution?

Listing the materials inside the Nolah Evolution is no easy feat, as this mattress has seven layers (including its top cover) and is 15 inches thick. You can order this mattress in one of three firmness levels: Plush, Luxury Firm, or Firm.

  • Layer 1 – Cover. An organic cotton cover with heat-transferring fibers.
  • Layer 2 – Pillow Top. A Euro topper quilted with breathable foam and encased by a gusset that further vents unwanted warmth.
  • Layer 3 – AirFoamICE™. This graphite-infused foam reputedly beats memory foam at pressure relief, cooling, and standing up to wear and tear.
  • Layer 4 – High-Resilience Foam. A firmer foam that supports the softer layer above.
  • Layer 5 – Transition Foam. Adds some bounce and responsiveness to the mix.
  • Layer 6 – Coil Unit. Three regions that provide specialized amounts of pushback to different parts of the body. Thicker coils around the bed’s perimeter lend the mattress remarkable edge support.
  • Layer 7 – Base Layer. A robust foundation made from recycled plant fiber.

Our Thoughts After Testing the Nolah Evolution 

This mattress was a universal hit. It earned perfect scores from us in all but two categories—pressure relief (4 out of 5) and motion isolation (4 out of 5). But a 4 is still a high score, and the Evolution appears to be a jack of all trades when it comes to comfort. 

Couples in need of a king-size bed should be pleased with the Evolution’s awesome edge support, responsiveness, and cooling. As for its motion isolation, it may not be perfect, but it’s pretty darn close.

One of our senior staff writers owns this bed, and because of it, she says she can finally achieve easy sleep next to her husband, who tends to fidget and flop “like a tilt-a-whirl at a county carnival.”

The Helix Dawn at a Glance

The spring unit and the proprietary foams in the Helix Dawn give it a firmer feel that’s perfect for people who prefer minimal sinkage. Instead of classic memory foam, this king-size hybrid features Helix Dynamic Foam—a material that emulates the airy feel of latex—as its first foam layer. 

What’s Inside the Helix Dawn?

The Helix Dawn is 11.5 inches tall and has five total layers.

  • Layer 1 – Cover. It comes with a soft cover, but for an extra fee you can exchange it for a GlacioTex™ Cooling Cover with fibers that help redirect excess heat.
  • Layer 2 – Helix Dynamic Foam. Emulates the responsive feel of latex.
  • Layer 3 – Helix Responsive Foam. Cradles pressure points.
  • Layer 4 – Transitional Foam. Another layer of Helix responsive foam for a firmer feel.
  • Layer 5 – Innerspring Unit. Individually wrapped springs that have been reinforced along the long edges.
  • Layer 6 – DuraDense Foam. A sturdy foundational layer.

Our Thoughts After Testing the Helix Dawn

Back and stomach sleepers should appreciate the even, stable support that the Helix Dawn offers.

We felt that we were resting securely “on top of” rather than “inside” the mattress, though it’s worth noting that this bed has a lower pressure relief score than average (3.5 out of 5). That means it’s probably too hard for side sleepers and some lightweight folks. 

In addition to a firm feel, this bed is also very bouncy. Its responsiveness is a benefit for combination sleepers who move around a lot, as well as for sexually active couples.

The Bear Star Hybrid at a Glance

The Bear Star Hybrid is often marketed to athletes, but its cooling components don’t discriminate—they should help anyone who tends to sleep hot. At the top of this bed is a cover that boasts temperature-regulating HydroCool® technology, and for an extra fee, you can add Celliant® fibers that allegedly transform body heat into infrared energy.

What’s Inside the Bear Star Hybrid?

The Bear Star Hybrid is a 13-inch mattress equipped with five layers.

    • Layer 1 – Cover. HydroCool® technology helps with temperature regulation, and optional Celliant® fibers may speed up muscle recovery after strenuous activity.

    • Layer 2 – Serene Gel Foam. Provides plushness and temperature regulation.

    • Layer 3 – Comfort Foam. Adapts to different body types and sleep positions—a benefit for couples sharing a king-size bed. Also serves as a transitional unit between the upper portion of the mattress and the coils below.

    • Layer 4 – Coil Unit. Ensures your spine remains well-aligned throughout the night. Stronger coils along the perimeter reinforce the edges of the bed.

    • Layer 5 – Base. A dense foam for added durability.

Our Thoughts After Testing the Bear Star Hybrid 

Stuart, another mattress tester for Sleep Advisor, noted that the cover on this bed immediately felt nice and cool to the touch. The airflow around its springs and the gel within its uppermost foam layer should also help keep the temperature down. 

As a hybrid, this bed gains a lot of support from its spring unit, but it’s also not overly bouncy. In fact, it’s actually better at motion isolation than you might think—it received a 4 out of 5 from testers in that category. A king-sized model should serve especially well for couples who run hot at night.

The Titan Plus at a Glance

If you’re a bigger person looking for a king-size mattress, the Titan Plus has you covered! This bed was designed to accommodate plus-size folks who often find themselves dissatisfied with other mattresses. Support is where the Titan Plus prevails, thanks to its industrial coil unit that should have you feeling lifted and aligned on the mattress surface.

What’s Inside the Titan Plus?

The Titan Plus is 11 inches tall. It has 4 internal layers and can accommodate up to 1,000 pounds.

  • Layer 1 – Gel Memory Foam (1 inch). This cooling foam layer contours to the body but reforms easily to its original shape.
  • Layer 2 – TitanFlex™ Foam (2 inches). A responsive layer of foam that also prevents pressure buildup.
  • Layer 3 – Coils (6 inches). Sturdy, individually wrapped coils make up the support unit. There are stronger coils along the edges for added reinforcement.
  • Layer 4 – High-Density Foam Base (2 inches). The dense, firm, foam foundation of the bed.

Our Thoughts After Testing the Titan Plus

Our heavyweight tester, Spencer, was a huge fan of this bed.

He felt loads of support accompanied by absolutely no pressure buildup, and even threatened to take the bed home because of how comfortable it felt.

As an average-weight sleeper, I thought the bed felt just a tad firm, and Loren—our most petite tester—agreed, though we couldn’t quibble with how lifted and and supported we felt.

The Titan Plus is another one of those rare hybrids that excels at motion isolation. It surprised us with how well it canceled out movements, and gave it a 4 out of 5 in this category.

A king-sized version of this mattress would work well for plus-sized folks who want to stay cool and spread out (its edge support is nothing to scoff at, either!).

Who Should Buy a King Mattress?

  • Couples and families. The best part about a king-size mattress is the amount of space you’re getting. Couples who want lots of room to stretch out should enjoy this size, and if you have children, there will probably be room to spare for when they want to rest (or jump) alongside you. 
  • Pet owners. In the same vein, folks who allow their pets into the bed may want the extra space to ensure that everyone’s comfortable.
  • People with large bedrooms. One drawback of a king-size bed is that it can take up a lot of space. If you have a fairly big bedroom, though, a king might be the perfect fit. Sometimes, a queen or full can look too small in larger rooms.
  • People who toss and turn. If you find yourself waking up on the opposite side of the bed from where you went to sleep, a king-size mattress may give you the room you need to sprawl and change positions. 
  • People who want a touch of luxury. Simply put, king-size mattresses look and feel luxurious. If you’re someone who wants their bedroom to be the ultimate restful retreat, a king may be for you. 

What to Consider When Shopping for a King-Size Mattress

Mattress Size

Did you know there’s more than one type of king-size bed? Actually, there’s more than five, and they all have different dimensions. 

How Big is a King-Size Bed?

A standard king-size mattress is 76 inches wide and 80 inches long. This is the most common incarnation of a king-size bed. Its dimensions make it a full 16 inches wider than queen beds, giving you more than a foot of added space from side to side.

King vs. California King

A California king mattress is slightly narrower and longer than a standard king, measuring 72 inches wide and 84 inches long. It’s also known as a Western king, Cali king, or Cal king.

So, why you might buy a California king over a standard king? Certain sleepers — especially tall ones — appreciate the extra length. Its dimensions may also work better with your bedroom setup.

The king vs. California king debate is long and storied, with good arguments on either side.

King vs. Alaskan King

An Alaskan king-size bed is 108 inches by 108 inches — in other words, a 9 foot by 9 foot square! That makes it about 2.6 feet wider and 2.3 feet longer than a regular king. It’s the largest king-size bed available that isn’t custom-made. 

These mattresses are much harder to find than regular king-size beds, and much more expensive. But some folks are willing to pay a large sum for all that extra space and luxury.

King vs. Wyoming King

The Wyoming king is a square mattress that measures 84 inches by 84 inches, a whopping 7 feet by 7 feet. It’s 8 inches wider and 4 inches longer than a standard king bed. 

King vs. Texas King 

A Texas king mattress measures 80 inches wide by 90 inches long (or 6.5 feet by 8 feet). It’s 4 inches wider and 10 inches longer than a regular king. 

King vs. Split King

A split king mattress is exactly what it sounds like: a king-size bed that’s been split down the middle into two separate sides. Usually, a split king is just two twin XL mattresses (measuring 38 inches wide by 80 inches long each) placed next to one other. 

Split kings are ideal for couples who want to sleep beside one another but have notably different preferences in terms of comfort. For example, maybe you like a soft mattress, but your partner prefers an extremely firm bed. With a split king, you won’t need to compromise.

This setup works optimally with a split adjustable base. Each sleeper gets the feel they want from their bed, and they can manipulate the head and foot on their side independently. 

The Different Types of King-Size Beds, Compared

Type of MattressDimensions (inches)
Standard King76″ x 80″
California King72″ x 84″
Wyoming King84″ x 84″
Texas King80″ x 98″
Alaskan King108″ x 108″
Split King30″ x 80″ and 30″ x 80″

Type of Mattress 

The type of king-size mattress you buy will affect how it feels, how much it costs, and how long it lasts.

Hybrid King Mattresses

Hybrid mattresses have a coil unit at the bottom for support and foam layers at the top for comfort and pressure relief. Because they combine the benefits of all-foam and innerspring beds, we recommend them more often than not.

Memory Foam King Mattresses

Memory foam mattresses excel at pressure relief and motion isolation in particular. They’re also a more affordable option than a hybrid bed. However, they may trap heat, and they typically can’t offer as much support as a mattress with springs.

Latex King Mattresses

Latex mattresses feature latex foam somewhere in their construction, whether it’s as a single comfort layer or the entirety of the bed. Latex foam is temperature-neutral, durable, and great for pressure relief. Natural and organic latex is also eco-friendly. The main downside to this material is its high price point.

Innerspring King Mattresses

Traditional innerspring mattresses have an interconnected coil system at the base, topped by a thin comfort layer. These beds aren’t very common nowadays due to the popularity and enhanced features of hybrid models.

Support

Consistent, even support is essential in a king-size bed. Otherwise, you may end up with a mattress that dips in the middle, causing you and your partner to roll into that indentation at night. 

How do we test support?

We lie down on each bed we test and assess how lifted we feel, and whether that support is present throughout the entire mattress. We take special notice of beds with zoned support—these mattresses, such as the WinkBed and Saatva Classic, provide extra lift under areas that need it most, namely the lower back.

A bed receives a high score in support if we feel evenly and thoroughly buyoed across body types and sleeping positions. It will get a low score if we feel that we’re sinking down too much or too unevenly in some areas.

Firmness

The firmness of your king-size mattress affects how comfortable you are and how soundly you sleep. Something overly soft can leave you feeling stuck in the bed, while something too firm can cause soreness around sensitive joints. 

Furthermore, the best firmness for a given person can depend on their body type and primary sleeping position. 

Body Type

Your weight and body type influence how firm a bed feels to you.

  • Petite people (those who weigh less than 130 pounds) tend to prefer softer beds, and are more sensitive to harder surfaces. 
  • Average-weight people (between 130 and 230 pounds) usually like a medium-firm bed that splits the difference between cushion and support. 
  • Heavyweight sleepers (who weigh more than 230 pounds) do best on firmer beds, which tend to provide lots of support. 
Saatva Classic Side Sleeping Testing
All three body types (lightweight, average-weight, and heavyweight) testing the Saatva Classic

Sleeping Position

There are three main sleeping positions: side, back, and stomach. Some folks rotate through more than one throughout the night, and they’re called combination sleepers. 

  • Side sleepers typically like a softer bed that relieves pressure from the hips and shoulders. 
  • Back sleepers, on the other hand, usually enjoy something that can distribute their weight evenly over the surface of the bed. A medium to medium-firm feel works best for these folks. 
  • Stomach sleepers need a firmer bed. A firm mattress helps to keep their hips elevated and level with their shoulders, whereas an overly soft bed could cause their hips to dip too low.
  • Combination sleepers need a bed that suits several sleeping positions, so a versatile medium-firm feel is ideal, along with enough responsiveness to help them move around.
How do we test firmness?

When we test a bed, we assign it a rating on our mattress firmness scale between 1 and 10. The higher the number, the firmer the mattress (1 would be softer than air, 10 would be as hard as cement).

Because we’re people with different body types, we consult with each other and agree on a firmness score that matches everyone’s experience of the bed.

Pressure Relief 

Beds that cradle your most sensitive spots can melt away aches and pains to bring restorative sleep. We say that these mattresses are good at pressure relief—they counteract pressure buildup around the places on your body that are bearing the most weight or force. 

Pressure relief is important for any mattress, including king-sized ones. Some people like a lot of it, whereas others prefer a bed with less. But a degree of pressure relief is what helps prevent the soreness and stiffness you’d probably wake up with if you slept on a totally rigid surface. 

How do we test pressure relief?

We use a pressure map on each bed we try. This map is color-coded to show areas of increased pressure buildup: blue and green mean less pressure, while red and yellow signify more pressure. We have testers of each body type lie on their back and side to get an accurate reading for each position.

Even in a large bed like a king, good edge support is beneficial, particularly to co-sleepers who spread out a lot. It allows couples to use the entire bed without feeling like they’re falling out of it. 

Additionally, reinforced edges can help those with mobility issues get in and out of bed more easily. Edges without enhanced support may dip too low and cause slipping. 

How do we test edge support?

We test out edge support in two positions: sitting on the edge while tying our shoes, then lying on the edge for about a minute. We make note of how much the edges sink as well as how secure we feel.

Motion Isolation

A king-size bed should give you plenty of room to move around, but if it doesn’t isolate motion well, you may feel every movement from a partner (or child, or pet). A bed with good motion isolation will dampen these movements so that you sleep on, undisturbed.

How do we test motion isolation?

We use a seismograph app to record movement across the mattress surface. The graphs look like a line with a lot of waves; smaller waves or straight lines mean little to no disturbance, while bigger waves mean more noticeable movement.

We’ll also lie side by side and see if we can feel a fellow tester’s movements to corroborate our findings.

Responsiveness

Responsiveness refers to how quickly and energetically a bed’s surface “bounces back” in response to your movements. It’s a helpful feature for combination sleepers, who change positions throughout the night and don’t want to feel stuck in a bed’s layers.

Because a responsive bed facilitates movement and bounce, it’s also the best type of bed for sex

How do we test for responsiveness?

We bounce a lacrosse ball and a weighted medicine ball on the bed to see how high the objects bounce and how quickly the mattress surface reshapes itself. Of course, we also jump on the bed too!

Cooling 

The size of a mattress doesn’t necessarily affect its ability to keep you cool, but if you’re sharing a bed, overheating becomes more likely. Many of the best king-size beds therefore have lots of cooling elements. 

Look for foams infused with cooling gels or copper, as well as spring systems that permit extra airflow. Beds like the Bear Star Hybrid and the Nolah Evolution take things a step further with their wealth of temperature-regulating materials. 

How do we test cooling?

We use a temperature gun to measure a bed’s cooling capability. First, we’ll take the surface temperature of the mattress (which is usually 74 degrees Fahrenheit at most in our studio).

Then, a tester lies on the bed for five minutes, and we take the temperature again. After another five minutes, we take the temperature a third time to see how much it’s changed (if at all). A bed that keeps its surface temperature within five degrees between these two readings has effective cooling materials.

How much does a king-size bed cost?

You can expect to pay at least around $1,500 to $2,000 for a quality king-size bed. However, certain luxury models can cost more than $5,000.

Is a king-size mattress better than a queen-size mattress?

A king-size mattress will be better for you if your bedroom is large enough and you need a lot of room to stretch out at night, especially if you share the bed with a partner, children, or pets.

A queen-size mattress is better if you’re trying to fit it in a smaller room, and you don’t mind snuggling up with any co-sleepers a bit more. It will also be somewhat more affordable than the larger model.

Both sizes have their pros and cons, but the decision ultimately comes down to the size of your bedroom, your budget, and your personal preferences.
