Casper was launched in 2013. Its flagship mattress model, the Casper, features a mixed memory foam and polyfoam comfort system and a high-density polyfoam support core.
Helix has been in business since 2015. The flagship model’s comfort system features three primary components: a layer of ‘Helix Dynamic’ polyfoam; pocketed microcoils; and standard polyfoam. Helix allows mattress purchasers to customize their mattress in terms of construction, firmness, and other factors; for this reason, the order and density of each comfort system layer will vary by selected design. The support core of this mattress is made of high-density polyfoam. Many reviews refer to this mattress as a ‘hybrid’; however, it does not meet the Tuck.com criteria for a true hybrid because it does not feature a coil-based support core.
Please note that Casper also offers the Casper Wave. This model is constructed with layers of polyfoam, memory foam, and latex in the comfort system. The Casper Wave is not included in this product comparison; only the flagship mattresses of both companies will be discussed.
The mixed foam mattress from Casper and the mixed foam and microcoil mattress from Helix have earned comparable customer satisfaction ratings. However, each model offers unique benefits and drawbacks for consumers. Our comparison page will rank both mattresses in terms of performance, firmness, size, and price-point, as well as the warranty, sleep trial, customer service, and overall company reputation of Casper and Helix.

Next we’ll compare the Casper and Helix mattresses by looking at performance metrics like durability, motion isolation, conforming/pressure relief, and edge support.
|Category||Criteria||Casper Rating||Helix Rating||What Users Say|
|Customer Satisfaction||Based on data collection, this is an overall customer sentiment regarding the Casper and Helix mattresses.||72%||71%||A single percentage point separates the customer satisfaction ratings of Casper (72%) and Helix (71%). Comparatively, both of these models are on par with the average customer satisfaction rating for all foam-based mattresses.|
|Durability||The average mattress will perform for at least seven years before it needs to be replaced||Good||Fair||The lifespan of the average Helix mattress is slightly shorter than the lifespan of a Casper; however, both brands are relatively new and the long-term durability of these mattresses has not yet been assessed.|
|Motion Isolation||Foam-based mattresses are designed to minimize motion and isolate it from other areas of the sleep surface, which can cut down on nighttime disruptions.||Fair||Good||According to our customer feedback, Casper mattresses do not isolate motion or cut down on nighttime disruptions as much as other competing, foam-based models (such as the Helix).|
|Sex||Foam-based mattresses are less responsive by design, and may not be as suitable for sex as innerspring or hybrid models.||Fair||Good||The Helix is slightly more responsive than the Casper (due in part to the pocketed microcoil layer), and is better for sex as a result.|
|Conforming||Foam-based mattresses conform closely to sleeper’s bodies, which can help align the spine, target pressure points, and alleviate back pain||Good||Good||Owners of both the Casper and Helix mattresses claim that they conform somewhat closely and alleviate bodily pressure to an acceptable degree.|
|Temperature Neutrality||Foam retains more body heat than other materials, and foam mattress owners often ‘sleep hot’ as a result.||Fair||Fair||Our reports indicate that both the Casper and the Helix can be heat traps, and owners may sleep warm as a result.|
|Off-gassing||Some mattresses emit particles when they are unpackaged, accompanied by unpleasant ‘off-gassing’ smells that can last for days.||Fair||Good||The Helix produces less off-gassing odor than the Casper, but neither brand is associated with particularly strong or long-lasting smells.|
|Edge Support||Because of their construction, foam-based mattresses often provide little to no edge support and may sink prematurely in areas of the bed where people tend to sit.||Fair||Fair||The Casper and Helix mattresses offer better-than-average edge support compared to other foam-based models, but customers seeking sturdy edge support may be more satisfied with an innerspring or hybrid model.|
|Noise||Foam-based mattresses create little to no noise, due to their lack of springs, coils, and other metal components||Excellent||Excellent||According to customers, both the Casper and the Helix are virtually silent.|
|Ease of Moving and Rotating||All mattresses are relatively heavy when it comes to moving and rotating, but some are heavier and more unwieldy than others.||Very Good||Good||The Helix is slightly heavier on-average than the Casper, but both mattresses are relatively light and easy to maneuver compared to other models.|
One’s experience with a mattress often comes down to two more factors: body weight and preferred sleep position. The next table uses both criteria to generate sleeper preference scores for the Casper and Helix mattresses.
|Sleeper Position||Sleeper Weight||Casper||Helix|
|Side||130 lbs or less||Very Good||Good|
|130 lbs to 230 lbs||Good||Good|
|230 lbs or more||Fair||Fair|
|Back||130 lbs or less||Good||Good|
|130 lbs to 230 lbs||Good||Fair|
|230 lbs or more||Good||Fair|
|Stomach||130 lbs or less||Good||Fair|
|130 lbs to 230 lbs||Good||Poor|
|230 lbs or more||Fair||Poor|
