Deciding Between Helix and Casper

Firmness / Feel

A mattress’ firmness is how soft or firm it feels to a sleeper. In the mattress industry, a firmness scale of 1 to 10 is used, with 1 being very soft and 10 being very firm. Most mattresses fall in the middle portion of the scale.

Firmness is both a preference and an important factor in ensuring the bed healthily supports your body weight and sleeping position. What’s “right” for a sleeper will vary based on the feel they enjoy, how they sleep and their body weight. For example, side sleepers need more contouring in the hips and shoulders, which, when allowed to sink deeper into the mattress’ top layers, encourage a neutral spine.

Average weight side sleepers usually find these qualities in a medium or medium-firm mattress, but heavyweight sleepers will need a medium-firm or very firm mattress to achieve this same feel and level of support. The opposite is true for lightweight side sleepers.

The Casper Original and Helix Midnight share a medium firmness level (6/10) that suits most lightweight and average weight sleepers. Both mattresses suit side sleepers, back sleepers, and stomach sleepers well, but side sleepers will appreciate the beds’ conforming top layers most. For a Helix mattress with a softer feel, try the Helix Moonlight or Helix Sunset. 

Motion Isolation

When you change positions or get out of bed, your body creates movement that may be felt by your sleeping partner. If you or your partner are light sleepers, this can create disturbances and prevent a restful night’s sleep. A bed’s ability to isolate motion is dependent on several factors, including its thickness, firmness level, and foam or latex layers.

In general, foam mattresses like the Casper Original isolate motion very well. Hybrids are usually more responsive but don’t isolate motion as well as foam. Some hybrids have built-in motion-isolating properties, and while the Helix Midnight has some aspects that encourage this, it still scores about average in this performance category. See our picks for the best mattress for couples that isolate motion and accommodate two sleepers well. 

Edge Support

Edge support, or how well the mattress withstands pressure at its edges, is an important consideration for certain people. For couples who share a space, edge support increases the area of sleepable space on the mattress. For some, it can be difficult to move in and out of the bed, making increased edge support important for their mobility. Edge support can be closely correlated with a mattress’ durability as well, so it’s never a bad idea to purchase a mattress that performs well in this category.

The Helix Midnight has exceptional edge support thanks to a high-density foam base that reinforces the pocketed coil layer. The Casper Original, like most all-foam beds, sinks significantly at its edges.

Pressure Relief 

Sleepers of all sizes and sleeping positions have pressure points, and a bed with pressure relief can help alleviate aches and pains to encourage a better night’s sleep. The comfort layers of a mattress are most influential in determining its ability to relieve pressure.

Both the Casper Original and the Helix Midnight provide comparable levels of pressure relief, although the Helix Midnight may slightly excel in this area. The Casper is a good mattress for back pain and have sensitive areas along their spines, while the Helix provides a more general close conforming feel.

Spine Alignment 

Even when you’re sleeping, your spine should remain as aligned as possible; this means your hips or shoulders shouldn’t sink too much. Beds that cater to your sleeping position and can adequately support your (or you and your partner’s) bodyweight are a good place to start when searching for this quality in a mattress.

The Helix Midnight’s comfort layers are made from memory foam, which will contour to the body and help improve spinal alignment, especially for side sleepers. Similarly, the Casper’s polyfoam and memory foam comfort layers provide the bed’s medium firmness and conform closely to help align the spine very well for side sleepers and well for back and stomach sleepers. The Casper’s Zoned Support provides softer support under the hips and shoulders with firm support underneath the lower back. See our other picks for the best mattress for back sleepers, protecting the lower back and propping up the hips.

Durability 

Durability refers to how long a mattress and its materials will last. Most mattresses in the industry have a lifespan of five to eight years with seven years being average. Both Casper and Helix are relatively new brands to the market, so they haven’t been around long enough for us to comment substantially on their longevity.

The quality of a bed’s construction and materials correspond closely with its durability, however, and both the Casper and Helix come from reputable makers. The bed’s support cores, 7.5” of high-density foam and a pocketed coil support core, respectively, may also help them last longer than competitors. For both, you can prevent body impressions and encourage longevity by rotating the mattress every three to six months.

Temperature 

A mattress’ ability to provide a cool night’s sleep will depend on its style and the materials used in its construction. The best cooling mattresses wick away heat from the sleeper’s body. In general, all-foam beds trap more heat than hybrid mattresses, which have breathable pocketed coil layers to encourage constant airflow. Many foam mattresses, however, now incorporate materials specifically designed to prevent heat retention, like gel-infused foams, open-cell foams and copper-infused covers.

The Casper offers a temperature neutral night’s sleep. It won’t trap body heat and sleeps somewhat cooler than other foam mattresses. The Helix Midnight (and all Helix beds) has standout temperature regulation. The coil layer promotes steady airflow and the comfort layers have lower-density foams to absorb less body heat and sleep cooler than other hybrid beds with more dense foam varieties.

Helix vs Casper Mattress Construction 

Helix Midnight Construction

The Helix Midnight is a hybrid mattress constructed with a 2-inch layer of PCF gel-infused memory foam, a low-density foam that absorbs very little heat when compared to foams of higher densities, allowing the surface of the mattress to sleep comfortably cool. The 1” transitional layer features Helix Dynamic Foam, which acts as a buffer between the sleepers and the dense support coils. 

The support core of the Helix mattress is 8-inches of pocketed coils and a 1-inch PCF high-density foam base. The pocketed coils stabilize the mattress, enhance responsiveness, reduce sagging, improve edge support, and promote airflow for a cool night’s sleep. The bed’s layers are encased in a stretchy polyester cover. Overall, the bed has a medium-firm feel that’s roughly a 6/10 on the firmness scale, and its layers contour to the body to alleviate pressure while providing even support. 

Casper Construction

The Casper is a mixed foam mattress with a polyester cover and polyfoam and memory foam layers. The comfort section of the mattress contains two 1.5” polyfoam layers and a middle 1.5” memory foam layer, which provides a medium feel that conforms closely yet supports the spine in proper alignment. 

The bed has a 7.5” high-density polyfoam base and measures 12” tall. Although its design is simple, the Casper provides strong overall support for a memory foam mattress. Lightweight and average weight sleepers should feel good on this bed in all positions, and the thick comfort section provides a plush, cushioned feel. However, see our list on the best mattress for stomach sleepers if you are looking for a mattress that may work for heavier sleepers and those who need extra support at the hips.

Our Helix vs. Casper Final Review

So, which is the best mattress? We’ll let you decide. The Helix Midnight and Casper share a lot in common, including price point, firmness level, foam types, and height. Both conform closely to the body and provide great pressure relief for less than $1,500 in all sizes.

However, we think the Casper is a better choice for shoppers looking for that signature memory foam feel. It’s plush, conforming top layers will give you the sensation of sleeping “in” the mattress rather than “on” it, and if that’s what you love, the Casper is your bed. See our list on best mattress for combination sleepers for mattresses that prop the sleep on top of the mattress and make it easier to change positions.

The Helix Midnight is a better choice for sleepers who tend to get hot throughout the night, as the pocketed coil support core will encourage temperature neutrality. It also offers better full-body support than the Casper, so back and stomach sleepers, especially those in the average weight category, may find that the Helix Midnight is a better fit than the Casper over time.
