Meet Our Testing Team
- Sleepers who prefer a balance of contouring and support. The Casper provides close body-conforming to alleviate pressure in sensitive areas, but the mattress has a more supportive feel than other all-foam beds.
- People who weigh 230 pounds or less. Due to its moderate firmness and close conforming, we recommend the mattress to lightweight and average weight individuals.
- Couples. The mattress isolates motion transfer very well and is virtually silent when bearing weight, making it optimal for people who awaken easily due to nighttime noises or their sleep partner’s movements.
- Those who normally sleep hot in foam beds. The Casper’s comfort foams absorb some body heat, but overall the mattress sleeps cooler than many competing all-foam models.
Not Recommended for...
- Sleepers who prefer very responsive mattresses. The Casper has slightly more responsiveness than most competing all-foam models, but it lacks the distinct bounce of innerspring and hybrid mattresses.
- People who weigh more than 230 pounds. Heavier individuals may find the Casper too soft and prone to sinking, which can lead to added pressure throughout the body.

How Is the Casper Mattress Constructed?
The top panel of the Casper’s cover is made of a blend of recycled polyester, polyester, upcycled cotton, rayon, and lycra. Each mattress cover contains up to 45 recycled plastic water bottles.
Casper recommends spot-cleaning with mild detergent should staining occur.
The Casper is constructed with two comfort layers. The top 1.5-inch layer is standard polyfoam, which is more responsive than memory foam. This gives the Casper a light bounce.
The second 2-inch comfort layer is made of memory foam, which is zoned to provide different levels of support for different body parts. This material is fairly soft. Combined with the more top polyfoam layer, the bed’s comfort system provides an even balance of body-contouring, pressure relief, and support.
The Casper’s support core contains 7 inches of PCF high-density polyfoam. This dense material stabilizes the bed and prevents the softer comfort layers from sagging too much. The support core also reinforces the perimeter, which protects the edges from sinkage in places where owners sit when getting in and out of bed.
The Casper measures 11 inches thick, making the mattress on the higher end of average compared to other mixed-foam and memory foam beds. Its base polyfoam layer is also thicker-than-average, resulting in strong overall support for sleepers, while the deep comfort layers offer ample cushioning and body-conforming.

What Are the Firmness and Feel Like?
The Casper has a medium (5) feel. Memory foam beds with the same firmness level often conform to the body very closely and provide less-than-ideal support. Since the Casper places a layer of polyfoam over its memory foam layer, the mattress feels more supportive as it cushions the body.
That said, the Casper’s medium feel is best suited to sleepers in the lightweight and average weight groups. Heavier individuals may experience excessive sagging, particularly around the shoulders and hips. This can lead to added pressure, and also interfere with spinal alignment.
For a more detailed breakdown, check out our sleeper ratings below.
Now, let’s look at our performance ratings for the Casper. These ratings are based on findings from our in-house testing crew, feedback from external sleep testers, and verified owner experiences.
The Casper has been available for purchase since 2014, giving us some time to test the mattress for durability. However, we have not yet been able to evaluate how the bed performs across the average mattress lifespan of six to eight years. Our durability rating for the Casper is based on its materials and quality of construction, owner experiences, and Casper’s reputation.
The Casper has an expected lifespan of about seven years, which is above-average for an all-foam bed. Most all-foam beds develop body impressions from sleepers over time, and these can affect how comfortable and supportive the mattress feels. The Casper’s more supportive structure makes it less susceptible to impressions, though they will likely begin to appear as the mattress nears the end of its lifespan.
The support core also plays a role in longevity. The bed’s high-density base foam measures 7 inches, which is fairly thick for the support layer of an all-foam bed. Generally, thicker support cores provide better stability than thinner base layers.
Owners can further protect their Casper from developing body impressions by rotating the mattress head-to-foot every three to six months.
To test motion isolation, we asked two testers to lie down on the Casper at the same time and feel for movement across the surface. Even when one of the testers got into and out of bed, neither person noticed any transfer whatsoever. These findings are consistent with feedback from our external sleep testers, including those who evaluated the mattress with sleep partners.
Most all-foam mattresses provide superior motion isolation compared to other bed types. The foam absorbs and minimizes transfer much better than latex, and the mattresses don’t have the coil support cores that give innerspring and hybrid models their signature bounce. Even compared to other all-foam mattresses, the Casper offers excellent motion isolation. This is definitely a key strength of the bed.
When unpacking the Casper, our testers noticed moderate off-gassing smells. They tested the mattress a few days later and could still detect some odor. We don’t believe excessive long-term off-gassing will be a major issue for most owners, but those who are sensitive to smell may notice odor for some time after the mattress is unboxed.
Off-gassing commonly occurs with new mattresses, particularly those with polyfoam and/or memory foam layers. Unpacking these beds releases volatile organic compounds (VOCs), which are generally harmless but carry a noticeable odor many people liken to rubber or plastic. Smells typically dissipate in a matter of days, if not sooner, but some beds carry more persistent odors.
Testers in different weight groups evaluated the Casper for pressure relief by lying on a sensory pad on top of the mattress, which measures pressure build-up in different areas of the body. They also checked to see if pressure increased or decreased after changing sleep positions.
Overall, our testing shows the Casper provides good pressure relief for lightweight and average weight sleepers. Our heavyweight testers found that the mattress sagged a bit, especially around the shoulders and hips, which led to added pressure. This is primarily due to the Casper’s medium feel, as heavier individuals tend to find firmer beds more supportive.
All of our sleep testers found that the Casper offers good temperature neutrality. The comfort layers absorb some body heat, but overall the mattress sleeps noticeably cooler than competing foam models. This can be attributed to above-average breathability in the top comfort layer.
All-foam mattresses tend to sleep hotter than innerspring or hybrid models because of differences in support core construction. Coil layers allow air to circulate, which helps cool off the interior of the bed and maintain a comfortable sleep temperature. Solid-foam base layers do not promote nearly as much airflow and tend to trap heat as a result, but all-foam beds can offset this issue by using more breathable foams and cover materials.
To test edge support, we asked people in different weight groups to sit along the perimeter of the Casper and feel for sinkage beneath their bodies. Like most all-foam beds, the Casper does sink a bit. However, its thicker-than-average support core reinforces the edges fairly well compared to its competitors.
We also asked our testers to lie down next to the edge of the Casper to see if they experienced feelings of “roll-off.” They found the perimeter fairly stable, although lightweight and average weight testers felt more comfortable about roll-off than heavier testers.
During our assessment, the testers noted that the Casper does not produce any noise when bearing weight. This characteristic, coupled with the bed’s excellent motion isolation, makes the Casper a great choice for people who are easily disrupted by their sleep partner’s movements during the night.
Casper’s lack of noise is to be expected. Most all-foam and all-latex beds are virtually silent. They lack the internal components normally associated with disruptive noises, such as squeaky coils found in innersprings and hybrids, or motorized chambers in airbeds.
Like many all-foam and memory foam beds, the Casper conforms closely to sleepers. This causes couples to sink too deeply into the surface, which inhibits movements and makes changing positions more difficult. On the other hand, deep sinking does provide better traction.
Many all-foam beds respond slowly as they conform to sleepers, which makes the surface less springy and not as conducive for sex. Bouncier beds, such as hybrids and innersprings, tend to be better for couples. The Casper has a slight edge in this category due to its moderate bounce, but some couples find it lacks the right level of responsiveness.
The ideal firmness and thickness settings for a mattress largely depend on a sleeper’s body weight, shape, and preferred sleep position. In order to better inform our readers and avoid subjectivity in our review, we evaluated the bed with sleep testers of varying body types and position preferences.
Lightweight Sleepers – Less than 130 lbs.
Our lightweight testers found the Casper very comfortable and supportive. Side sleepers experienced full spinal alignment thanks to sufficient cushioning beneath their shoulders and hips, resulting in consistent pressure relief. Back- and stomach-sleepers weighing less than 130 pounds also enjoyed the mattress because of its above-average support.
Generally, lightweight sleepers prefer soft to medium surfaces because they contour to the body, alleviate pressure, and help align the spine. These sleepers do not sink as deeply into firmer beds and often experience added pressure.
Average Weight Sleepers – 130 to 230 lbs.
Like our lightweight testers, average weight sleepers also found the Casper comfortable. This was particularly true for our average weight side sleepers, who experienced a comfortable balance of contouring pressure relief and even support. The back- and stomach-sleepers weighing 130 to 230 pounds also enjoyed the mattress, but did feel some added pressure in the shoulders and hips.
Mid-level firmness is often ideal for average weight sleepers. The bed doesn’t sink too deeply beneath their bodies, but the comfort layers conform and align the spine to a pressure-relieving extent.
Heavyweight Sleepers – More than 230 lbs.
According to our heavyweight testers, the Casper was too soft and did not provide enough support for their bodies. The back- and stomach-sleepers experienced the most added pressure. Side-sleepers weighing more than 230 pounds found the Casper a bit more comfortable, but they also felt some pressure in the hips and shoulders.
Heavier individuals tend to prefer medium-firm to firm mattresses because they offer an even plane for sleeping. Softer mattresses often sink too much, which compromises support and may lead to discomfort.

How Does the Casper Mattress Compare to Other Beds?
We urge all mattress shoppers to compare multiple brands and models before deciding which bed is best for them. Next, we’ll see how the Casper Mattress stacks up against other Casper models and some similar mattresses from competing brands.
Casper vs. Casper Hybrid
In 2019, Casper introduced the Casper Hybrid, a new design based on the original Casper model. Both the Casper and the Casper Hybrid share the same materials in the comfort layers. Additionally, each bed has a 12-inch profile and a medium feel, though the Casper Hybrid is slightly firmer.
Support core construction is the key difference between these two beds. The Casper Hybrid – like other hybrid models – has a support layer composed of pocketed coils. A high-density polyfoam encasement around the coils adds extra reinforcement to the perimeter. The coils circulate more air than the Casper’s polyfoam support core, giving the hybrid better temperature neutrality, while the encasement offers improved edge support over the original. At the same time, the Casper provides better motion isolation and alleviates more pressure for sleepers under 230 pounds.
The Casper Hybrid is more expensive than the Casper, but still costs much less than the average model. Before choosing one model over the other, sleepers should determine which they prefer: the pressure-relieving cradle of an all-foam bed, or the responsive surface and cooler temperature of a hybrid.
Casper vs. Casper Wave Hybrid
Like the Casper Hybrid, the Casper Wave Hybrid is a newer hybrid version of the preexisting Wave model. The Wave Hybrid shares its predecessor’s comfort layers, but adds a transitional layer of gel-infused polyfoam and swaps the old support core with foam-encased pocketed coils.
The Wave Hybrid has a medium-soft feel, but its pocketed coils also make the surface fairly responsive. The result is a good balance of conforming and support, similar to the Casper’s – though the Wave Hybrid has more bounce. The coils also promote steady airflow to give the hybrid very good temperature neutrality, while the high-density perimeter foam prevents the edges from sinking too much. The Casper performs better in other areas, including motion isolation, pressure relief, and noise potential.
Ultimately, most buyers will choose the Casper or the Wave Hybrid based on price-point. The Wave Hybrid is Casper’s most expensive mattress and costs more than twice as much as the Casper. The hybrid’s luxurious feel may entice some shoppers with bigger budget, but the Casper offers more value for sleepers.
Casper vs. Casper Element
The Casper Element is constructed with a polyfoam comfort layer and a high-density polyfoam support core. Somewhat similar to the Casper Original, the Element measures 10 inches thick and has a medium-firm (6) feel. The Casper and the Element share other key qualities, as well. Both beds isolate motion transfer very well and produce virtually no noise, making either a good choice for couples.
However, they are very different in several ways. Although the Element is firmer, the Original’s much thicker support core ensures better overall support for sleepers across all weight groups. The Casper Original’s softer comfort materials also provide a more comfortable surface for lighter individuals, side-sleepers, and people with pressure-point issues.
The Element has a much lower price-point than the Casper, and this may be a deciding factor for some. However, the Casper outperforms the Element in most key areas.
Casper vs. Casper Nova Hybrid
The Casper Nova Hybrid, one of Casper’s newest models, is a hybrid mattress with a plush, breathable surface. Both models share the same top layer, but the Nova Hybrid has a plusher feel on the surface and a pocketed coil support core.
The Nova Hybrid has a Medium Soft (4) feel, but its pocketed coil support core ensures a significant degree of support. Like the Casper, it features a layer of polyfoam on top. Under that is an additional layer of polyfoam, this one zoned to support different parts of the body most effectively. Under that is their Zoned Support Pro layer, another zoned polyfoam layer with 7 different zones. This is all over a pocketed coil support core.
The softer comfort layers give the Nova Hybrid even better pressure relief than the Casper Original, and the pocketed coil support core makes it more breathable and durable. The Nova hybrid is a bit more supportive, but still isn’t ideal for sleepers over 230 pounds, especially stomach sleepers. Nonetheless, the Nova Hybrid is around twice as expensive as the Casper Original.
Casper vs. Purple
Like the Casper, the Purple was one of the pioneering bed-in-a-box mattress models. Both models isolate motion transfer very well, and their price-points are comparable, but apart from these similarities the mattresses are very different.
The Purple features the Smart Grid comfort layer, which is composed of a signature elastic polymer material. The Smart Grid contours to the body like memory foam, but is also more responsive and sleeps exceptionally cool. The Casper has a softer feel thanks to its polyfoam and memory foam layers. The Purple’s support core is also 3.5 inches shorter than the Casper’s, giving the latter much better overall support.
The Casper and Purple have comparable price-points. Hot sleepers may want to consider the Purple, while those seeking a more supportive mattress should opt for the Casper. To learn more, check out our Casper vs. Purple Mattress Comparison.
Casper vs Tuft & Needle
The T&N Mattress from Tuft & Needle is an all-polyfoam mattress built with a graphite-infused comfort layer and a 7-inch, high-density support core. Like the Casper, the T&N Mattress offers better support than most all-foam models due to its thick base layer. Both beds also offer a good balance of cushioning and support thanks to their polyfoam top layers.
The T&N Mattress is slightly firmer, and considered a medium-firm (6.5). This makes it more suitable for average weight and heavyweight sleepers, while it may be a bit too firm for those who weigh less than 130 pounds. The Casper provides a more mid-level feel, though it feels less supportive for heavier ones.
The T&N Mattress has a lower price-point than the Casper, but neither is considered overly expensive. Shoppers should base their decision between these two beds on firmness preference, as well as their own body type.
