Casper Sleep launched in 2013, and began selling mattresses the following year. Casper currently offers three mattress models. The Casper and The Essential are constructed with memory foam comfort systems, while The Wave has layers of memory foam and blended latex in the comfort system.
Amerisleep was established in 2007. The company currently offers five memory foam mattress models, each of which has undergone a recent name change: the AS1 (formerly the Americana), the AS2 (formerly the Revere), the AS3 (formerly the Liberty), the AS4 (formerly the Colonial), and the AS5 (formerly the Independence). Although individual specifications vary, all five models feature memory foam comfort systems and polyfoam support cores.
Both Casper and Amerisleep have earned average to above-average customer satisfaction ratings. This page will compare both brands in terms of pricing, construction, and mattress performance, as well as company policies regarding shipping and delivery, returns, and warranty coverage.

This next table compares Casper and Amerisleep mattresses based on performance factors like durability, motion isolation, edge support, and noise potential. All ratings are generated from authentic customer and owner experiences.
| Category | Criteria | Casper Rating | Amerisleep Rating | What Users Say |
| Customer Satisfaction | Based on data collection, this is an overall customer sentiment regarding the X and Y mattresses. | 74% (The Wave) 72% (The Casper) 69% (The Essential) | 82% (AS3) 75% (AS5) 73% (AS4) 71% (AS1) 69% (AS2) | Customer satisfaction with both Casper and Amerisleep mattresses varies by model, but the AS3 and AS5 have earned higher ratings than any of Casper’s current models. |
| Durability | The average mattress will perform for at least seven years before it needs to be replaced | Fair (all models) | Fair (All models) | Amerisleep mattresses have durability that is on par with the average memory foam model, or roughly six years. Durability is questionable for Casper mattresses due to limited brand history, but it appears to be fair or better. |
| 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. | Very Good (all models) | Very Good (All models) | Motion isolation is a strong point for both mattress brands, with many owners saying their bed absorbs and minimizes motion transfer to a significant extent. |
| Sex | Foam-based mattresses are less responsive by design, and may not be as suitable for sex as innerspring or hybrid models. | Fair (The Essential) Good (The Casper and The Wave) | Fair (AS3, AS4, AS5) Good (AS1, AS2) | Neither Casper nor Amerisleep mattresses are particularly responsive nor bouncy, but some may be more suitable for sex than others. |
| Conforming | Foam-based mattresses conform closely to sleeper’s bodies, which can help align the spine, target pressure points, and alleviate back pain | Fair (The Essential) Very Good (The Casper and The Wave) | Good (AS1, AS2) Very Good (AS3, AS4, AS5)
| Apart from The Essential, AS1 and AS2, all current mattresses from Casper and Amerisleep offer exceptionally close conforming and above-average pressure relief. |
| Temperature Neutrality | Foam retains more body heat than other materials, and foam mattress owners often ‘sleep hot’ as a result. | Good (The Essential) Very Good (The Casper and The Wave) | Fair (All models) | Amerisleep mattresses tend to sleep somewhat hot, and all three Casper models sleep cooler by comparison. |
| Off-gassing | Some mattresses emit particles when they are unpackaged, accompanied by unpleasant ‘off-gassing’ smells that can last for days. | Fair (The Casper and The Essential) Good (The Wave) | Good (All models) | Odor potential is somewhat high for The Casper and The Essential, but The Wave and all five Amerisleep mattresses very little off-gassing. |
| 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 (The Casper and The Wave) Poor (The Essential) | Poor (All models) | Edge support is a chief complaint among Amerisleep owners, as well as The Essential owners. The Casper and The Wave are somewhat sturdier around the edges. |
| Noise | Foam-based mattresses create little to no noise, due to their lack of springs, coils, and other metal components | Excellent (all models) | Excellent (All models) | According to owners, all Casper and Amerisleep mattresses are virtually silent when bearing weight. |
| 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 (The Casper and The Essential) Fair (The Wave) | Fair (All models) | The Casper and The Essential are exceptionally lightweight and fairly easy to move; The Wave and all five Amerisleep mattresses are much heavier by comparison. |
Body weight and sleep position are two important factors to keep in mind when selecting a new mattress. The next table compares Casper and Amerisleep mattresses based on feedback from sleepers in different weight and sleep position groups.
