Helix vs. Casper: How Are They Similar?

• Firmness – Both the Helix Midnight and Casper have a medium-firm feel.
• Memory foam – Each bed has memory foam within it.
• Height – The Helix and Casper are nearly identical in height. The Helix is 11.5 inches tall, while the Casper is 11 inches tall.

Helix vs. Casper: How Are They Different?

• Mattress type – Helix Midnight is a hybrid bed, while the Casper is an all-foam bed (though there is a Casper Hybrid version available too).
• Zoned support – The Casper has a firmer center to keep the hips lifted and promote good spinal alignment, while the Helix doesn’t have this feature.
• Perforated foam – You’ll find perforated foam in the Casper, which helps promote airflow. The Helix is made with different types of foam that aren’t perforated.

Helix vs. Casper: Firmness, Feel, and Construction

Firmness & Feel

We use our firmness scale of 1-10 to rate beds from very plush to very firm. The majority of beds fall somewhere in the middle. The Helix Midnight and Casper both received a medium-firm rating from our team.

Mattress	Sleep Advisor Firmness Rating	Feel	Tester Feedback
Helix Midnight	6/10	Medium-Firm	The Helix has a balanced blend of softer foam layers up top, and a firmer supportive coil system beneath that creates an overall medium-firm feel. This versatile and moderate firmness should suit many side, back, and stomach sleepers.
Casper	6/10	Medium-Firm	The Casper has soft, cradling memory foam that hugs your body as you sink into the bed, but its built-in transitions between each foam layer help keep you sleeping on top of the bed, rather than in it. It also feels medium-firm, though a tad softer than the Helix.

Mattress Construction

The Helix Midnight and Casper are similar in height (11.5 inches for the Helix and 11 inches for the Casper). While you’ll find memory foam in each bed, the Casper has perforated memory foam to allow for greater airflow. It also has zoned support, for a firmer center of the bed to keep your spine in a natural S-curve. 

The biggest difference is the type of bed; the Helix Midnight is a hybrid build, while the Casper is an all-foam bed.

Helix vs. Casper: Mattress Testing Performance

Pressure Relief

• Helix Midnight Pressure Relief Score: 5/5

• Casper Pressure Relief Score: 4/5

We use a pressure map that generates a colored image identifying any areas of pressure buildup. The Helix Midnight was mostly blue and green, signaling low pressure, while the Casper had slightly less sinkage than your traditional foam bed, so it wasn’t as cradling. This could lead to pressure buildup for lightweight side sleepers and heavier back and stomach sleepers.

Support

• Helix Midnight Support Score: 5/5

• Casper Support Score: 5/5

We gauge support by lying on each bed on our side, back, and stomach. We check to see if our spine maintains its natural alignment and we don’t “bottom out,” or sink into the middle of the bed. Both the Helix and Casper had fantastic 5 out of 5 support with an “on top of the bed” feeling.

Motion Isolation

• Helix Midnight Motion Isolation Score: 5/5

• Casper Motion Isolation Score: 5/5

We use a seismograph app to measure movement transfer while our fellow testers shift around on the bed. This is an important feature for couples or those who share their beds with their pets since they’ll be less likely to be disturbed by any moving around. Luckily, both the Helix and Casper did a fantastic job of absorbing movement. We picked up only minimal motion transfer on our app, and we barely felt our teammates moving around.

Temperature Regulation / Cooling

• Helix Midnight Cooling Score: 5/5

• Casper Cooling Score: 4/5

A heat gun helps us measure the temperature of a mattress before lying on it and then after lying on it for five and 10 minutes. We found the Helix superior in cooling, which is likely due to its coil system. It helps “push” air throughout the bed as you compress the coils by laying on the mattress. 

As an all-foam bed, the Casper was slightly less powerful in cooling, even with its perforated foam. Foam beds are known for trapping heat, so this didn’t come as a huge surprise.

Bounce 

• Helix Midnight Bounce Score: 3.5/5

• Casper Bounce Score: 3/5

We test bounce by dropping a ball on a bed. We then watch how quickly the bed “bounces” back into its original shape. The Helix and Casper performed similarly, and although they both had average responsiveness, we found the Helix slightly bouncier — also probably because of its springy coil layer.

Edge Support

• Helix Midnight Edge Support Score: 2/5

• Casper Edge Support Score: 4/5

Edge support is how sturdy the perimeter of a bed feels, which is important for anyone who uses this area often, such as people with limited mobility who may need this feature to help them get in and out of bed. We test edge support by lying and sitting on the edge of a mattress — both for a minute. 

When she tested this on the Helix Midnight, Loren experienced substantial edge sinkage that made her feel like she might roll off the bed, which is why we rated it a 2 out of 5. The Casper felt more stable with minimal sinkage, which is likely due to its firmer foam layers that aren’t as contouring as other foam beds.

Couples

• Helix Midnight Couples Score: 3/5

• Casper Couples Score: 4/5

We give out our couples score based on features that could make (or break) the bed-sharing experience, like cooling, motion isolation, bounce, and edge support. We gave the Helix a 3/5 since it had poor edge support and average bounce, but rated the Casper slightly higher with its stronger edge support, which is helpful for couples because it gives them more space to spread out.

Accessibility 

• Helix Midnight Accessibility Score: 4/5

• Casper Accessibility Score: 4/5 

Accessibility refers to any ways the mattress and its design, performance, or policies go above and beyond. 

The Helix Midnight has an impressive 1,000-pound weight that’s highly accommodating for co-sleepers. The brand also partners with showrooms across the country so you can test the mattress in-store. This bed didn’t get a 5 out of 5, however, because their white glove delivery is only available in certain areas.

The Casper has zoned support and solid cooling features for a budget bed, including perforated foam that promotes airflow. We took off a point here because the white glove delivery costs extra, and the cooling, while good, wasn’t as advanced as we hoped it would be considering its cooling materials.

Customer Service

• Helix Midnight Customer Service Score: 4/5

• Casper Customer Service Score: 5/5

After reaching out to both Helix and Casper customer service, we found that Casper ranked supreme. Not only does the brand have in-house sleep specialists that you can speak with, but their customer service can be reached via email, phone, or online chat. Helix also offers chat, email, phone, and text customer service options, but we found the chat somewhat difficult and tedious to use.
