Helix is known for their line of high-quality bed-in-a-box mattresses that ship right to your door. We love that Helix allows you to choose between many firmness options, and their Helix Moonlight mattress stands out as the softest from the brand.
The Moonlight combines a softer feel with a hybrid construction that we think could be exceptional for those in search of great pressure relief from a mattress. In this review, we’ll go over our testing findings for the Helix Moonlight.

Helix Moonlight Mattress Performance Ratings
How the Helix Moonlight Compares
Here at Sleep Advisor, we’ve tested over 150 different mattresses. The Helix Moonlight outdoes other mattresses we’ve tested in its overall score, cost, pressure relief, cooling, bounce, edge support, and compatibility for couples. It’s also just slightly taller but only by half an inch.
| Test | Helix Moonlight | Average |
| Overall | 4.3 | 4.1 |
| Mattress Height | 11.5″ | 11″ |
| Sleep Trial | 100 Nights | 141 Nights |

| Bounce | 5 | 4 |
| Edge Support | 4 | 3.9 |
| Couples | 4 | 3.9 |
Who We Recommend the Helix Moonlight For:
- Hot sleepers – The Helix Moonlight has some basic cooling features that should be good for most hot sleepers. The construction starts with a Soft Touch design cover that’s cool to the touch and breathable. On top of that, there are coils to help with airflow so that the bed doesn’t trap heat.
- Back and side sleepers – We think this bed is a great option for lightweight back sleepers and lightweight and average-weight side sleepers. They should experience enough support and pressure relief in these positions.
- Those with joint pain – This bed’s softer feel could make it a good option for people with joint pain. The construction offers enough cushioning and pressure relief around the sensitive areas such as the hips and shoulders.
Who We Don’t Recommend the Helix Moonlight For:
- People who prefer all-foam beds – This is a hybrid and a bouncy one at that, so if you’re a fan of the slow-sinking feeling that memory foam provides, you might want another bed.
- Stomach sleepers – Stomach sleepers often need firm support to keep their hips from sinking. We don’t think stomach sleepers will get the lift they need from the Moonlight.
- Heavier sleepers – People weighing over 300 pounds will experience the Moonlight mattress as even softer, and this could compromise their body alignment. Instead, we recommend a mattress specifically made for heavy sleepers.
Customer Reviews of the Helix Moonlight Mattress
On the Helix website, the Moonlight has over 1,000 reviews and a score of 4.4 out of 5, with customers explaining that it feels like sleeping on a cloud. Many also reported how it helped them with chronic back and neck problems. Those who scored it low disliked its firmness.
Testing the Helix Moonlight Mattress
Sleep Advisor’s Testing Methodology
Our review of the Helix Moonlight is based on in-person testing from our mattress testers. When we test mattresses, we focus on the overall feel and performance, but we also look at specific factors such as cooling, motion isolation, edge support, bounce, and more. We also tested the mattress in each sleeping position to evaluate who it would be the best for.

Firmness & Feel
Firmness Scale: 6/10
At Sleep Advisor, we rate mattress firmness on a scale of 1 to 10, with 1 being the softest and 10 being the firmest. When it comes to the Helix Moonlight, we think it feels like a 6 out of 10, which is a feel we’d describe as medium-firm. Although this is not the softest feel out there, it is among the softest models from Helix.
How Does the Helix Moonlight Mattress Feel?
The Helix Moonlight has a softer feel because of the pillow top, which is why we were surprised to find as much bounce as we did. Most soft-feeling beds let you sink right away, but the Moonlight feels more supportive since it cushions and contours your body only at the surface.
Sleeping Positions for Different Body Types
According to Helix, the Helix Moonlight can support up to 1,000 pounds, which is 500 pounds per side.
Side Sleepers
- Lightweight Sleepers – We think the Helix Moonlight might be a good fit for lightweight side sleepers. The pillow top should deliver enough cushioning to accommodate these sleepers.
- Average Weight Sleepers – Average-weight sleepers should like the soft feel of the pillow top to help reduce pressure in the hips and shoulders.
- Heavyweight Sleepers – Heavyweight side sleepers will sink deeper into the pillow top. However, we think there’s still enough support underneath to make the Moonlight a good fit for this group.

Back Sleepers
- Lightweight Sleepers – We expect this bed to offer adequate support for back sleepers under 130 pounds since they don’t press so deeply into the pillow top.
- Average Weight Sleepers – Back sleepers weighing 130 to 230 pounds should feel supported and cushioned, although those closer to 230 pounds might want more lumbar support.
- Heavyweight Sleepers – We think the Helix Moonlight is too soft for heavy back sleepers as it doesn’t offer enough support in the lumbar area, which could result in back pain.

Stomach Sleepers
- Lightweight Sleepers – This bed might not be firm enough even for lightweight stomach sleepers, except maybe the most petite ones.
- Average Weight Sleepers – We think average-weight stomach sleepers will notice their hips dipping down into the pillow top, which can cause the lower back to hyperextend.
- Heavyweight Sleepers – We found this Helix mattress to be too soft to support the heaviest stomach sleepers. Instead, heavyweight sleepers should check out the brand’s Helix Plus model, as this is specially made for this weight group.

Pressure Relief
5/5
From our experience, this Helix mattress should provide excellent pressure relief, particularly for lightweight and average-weight sleepers. The softer pillow top and comfort layers allow you to sink just enough to cushion the most sensitive areas, such as the hips, knees, and shoulders.
Is the Helix Moonlight Good for Pain Relief?
The Helix Moonlight can be a good option for people with pain, especially those with achy joints. This is because the bed’s softer feel cradles the body at the surface level, offering enough cushioning to help relieve tension. However, your weight and sleep position can also impact whether a bed would be helpful for pain relief.
| Back Pain | We think this bed should be a good fit for some lighter-weight people with back pain. However, those weighing above 130 pounds may not get enough spinal support from this bed if they’re a strict stomach or back sleeper. Read more about mattresses for back pain here. |
| Hip Pain | The Helix Moonlight does a good job of cushioning the hips while the coils support the entire body in alignment. This helps ease the hip pain by allowing a bit of sinkage, but we advise you to also consider your preferred sleeping position and body weight. Heavier people and stomach sleepers with hip pain might prefer a firmer mattress since we think the Moonlight could make hip pain worse for these folks. Read more about mattresses for hip pain here. |
| Shoulder Pain | This Helix model should be a good pick for those who usually experience shoulder pain when sleeping on their side. This can sometimes be the result of sleeping on a bed that’s too firm, so having that soft cushioning provided by the pillow top could make all the difference. Explore more mattresses for shoulder pain here. |
Support
4/5
Helix beds are known to combine support with pressure relief, and the Moonlight is no different. The support layer is made up of individually wrapped coils to help keep the body aligned.
However, this bed’s softer feel also means it doesn’t offer as much support across different weight groups and sleep positions compared to other Helix models. It should be a good option for lightweight and average-weight sleepers, but even in this case, you should be careful if you’re a strict back or stomach sleeper. For this reason, we gave it a 4 out of 5 here.
Motion Isolation
3/5
Motion transfer is helpful for couples and co-sleepers, especially if you usually wake up when someone moves on the other side of the bed. Since the Helix Moonlight is on the softer side and has coils, most of the movement from one side can be felt on the other side. This might not be important for solo sleepers or those who don’t wake up easily, but it could be a dealbreaker if you’re a light sleeper.
Temperature Regulation / Cooling
4/5
If you’re someone who often overheats at night, we recommend a high-quality cooling mattress. When it comes to this performance category, we noticed the Helix Moonlight has good breathability and cooling, given the specific features it comes with. The Soft Touch cover is naturally breathable, but you can also upgrade to a GlacioTex cover that’s designed for those who need more advanced cooling. Also, the coils are helpful for extra airflow. Since this model doesn’t have the advanced cooling cover (unless you pay extra), we gave it a 4 instead of a 5.
Bounce
5/5
The Helix Moonlight’s high amount of bounce earned it a perfect score here. The coils in this bed give off a springy feel.
You might not notice the bounce right away if you just press into the softer pillow top, but you should notice the coils spring back right away if you press deeper into the mattress. We think this is great for sexually active couples, combination sleepers, and people with mobility issues, as it can help with repositioning and getting in and out of bed.
Edge Support
4/5
The Helix Moonlight might be on the softer side, but we found it does a good job of keeping the edges from collapsing. The perimeter is reinforced with additional pocketed coils to help with edge support. Sleepers should feel secure enough when lying near the edge, although sitting might not feel as comfortable due to the softer pillow top, which is why it got a 4.
Accessibility
4.5/5
In this category, we look at what the mattress brings to the table in terms of performance, features, and policies. The Moonlight mattress is marketed toward back and stomach sleepers, but we think it actually fares better for side sleepers and only average-weight and lightweight back sleepers. This bed comes also with an appealing 100-night trial, free shipping and returns, and a 10-year warranty.
While it did perform well in many of our tests, we took off a point because we don’t think it’s firm enough for stomach sleepers or heavier back sleepers, and the advanced cooling costs extra.
Customer Service
4/5
Helix is a reliable brand that upholds warranty and policies without argument. As said, shipping is free, and so is returning the mattress. Communication is also simple enough, as you can reach them via email, phone, and online chat that’s available during normal business hours.
Performance for Couples
4/5
When deciding if a mattress is good for couples, we look at categories such as overall support cooling, motion isolation, bounce, and edge support. We also look at the bed’s weight capacity and firmness to make sure it’s versatile enough to accommodate two different sleepers.
In the case of the Helix Moonlight, it performed well in most categories with the exception of motion isolation. It also has that middle-ground medium-firm feel and a 1,000-pound weight capacity.
However, we gave it a 4 because it underperformed in motion isolation. That said, if neither of you is a light sleeper or a strict stomach sleeper, it should do well for you.

Preference-Based Features
Made in the USA
Anyone who likes shopping locally will appreciate Helix’s USA-based manufacturing. All their beds are custom-made in the States. Explore more mattresses made in the USA here.
Bed-in-a-Box
Helix is a bed-in-a-box company that ships their mattresses to your door in a box. Shipping is free, and setup is easy, which is good to know because these beds tend to be quite heavy.
Adjustable Base Compatible
This mattress works with most bed foundations and bases, including adjustable frames. Helix specifies that you should use a platform or slat-based foundation with slats no further than 5 inches apart. A traditional box spring is not recommended for this Helix mattress.

Construction: What’s Inside the Helix Moonlight?
The Helix Moonlight is a hybrid with soft foam and supportive coils, stacking up to 11.5 inches in total. The Luxe version is taller, standing at 13.5 inches tall together with the pillow top. The surface of this mattress features a Soft Touch design cover that’s cool to the touch and smooth. You can upgrade it to the GlacioTex™ for even more cooling.
- The comfort layer is made from latex foam that’s contouring and soft to hug the curves and relieve pressure.
- The transition layer is a bit firmer, providing ergonomic support. It’s still cushioning, but the added firmness makes it a good transition to the coils.
- The support layer features up to 950 individually wrapped coils that give this Helix its support, breathability, and most of all, bounce.
- The base layer is made from DuraDense foam that supports the upper layers, making the bed more durable.
Unboxing & Off-Gassing
The Helix Moonlight arrives at your doorstep in a box. We found it takes 10 to 15 minutes to unbox and set up, but we advise you to get some help as it can be quite heavy. The Queen alone weighs 100 pounds.
If you notice any off-gassing when you open the packaging, we recommend you let the mattress sit in a well-ventilated room for at least 48 hours. This way, it will have enough time to inflate and come to its full size, and all the odors will dissipate as well.
Certifications
- CertiPUR-US® – The foams in this bed are CertiPUR-US® certified. CertiPUR-US® is a third-party program that ensures the foams meet rigorous health and safety standards. This means they don’t contain harmful substances like ozone depleters, PBDEs, heavy metals, formaldehyde, and phthalates. They should also have low volatile organic compound (VOC) emissions.
- GREENGUARD Gold – This bed is also GREENGUARD Gold certified for low chemical emissions.
Noteworthy Updates
Helix offers an updated version of this bed called the Moonlight Luxe, which comes with an additional layer, a Tencel™ cover, targeted zoned lumbar support, and a longer warranty.

Helix Moonlight Mattress FAQs
Do Helix mattresses sag?
Helix mattresses are built to last for years to come thanks to the high-quality materials in them. We don’t think the Moonlight should sag as it has sturdy coils, even around the perimeter. However, remember to use the right base with slats no further than 5 inches apart.
How long do Helix mattresses last?
Helix models should last 10 years, which is great since the company offers a 10-year warranty for their core collection.
Is the Helix Moonlight good for side sleepers?
We think the Moonlight is a good option for side sleepers who need more cushioning. This bed has a softer pillow top that hugs the hips and shoulders, which is where your weight and pressure gather in this position.
What happens if I don’t like my Helix mattress?
If you find that the Helix Moonlight doesn’t fit your needs, you can return it before the trial is up. As mentioned, you should keep it for at least 30 nights because this is how long the company says it takes for you to get used to sleeping on a new mattress. If you still don’t like it, reach out to a team member at Helix, and they’ll arrange a pickup before they refund your money.

Our Verdict of the Helix Moonlight Mattress
Helix offers many options ranging from soft to firm. The Moonlight is one of their softest models and is also among the most affordable, though that doesn’t mean it lacks in quality craftsmanship.
We think the innerspring layer gives it enough bounce for those who prefer springy beds. On the other hand, there’s enough cushioning and softness coming from the pillow top to hug your body in all the right places. Although it doesn’t have the best motion isolation, consider if this is important to you. Overall, the Helix Moonlight earned a 4.3 out of 5.
