Deciding between the Casper memory foam mattress and the Saatva innerspring mattress? These two popular options shine in different ways for specific sleeper types. Learn which is right for you in this mattress comparison.
The Casper mattress is an all-foam mattress that conforms to the body for pressure relief and support in all four sleeping positions. The Saatva is a luxury hybrid mattress with thick comfort layers, three firmness setting options and a coil-on-coil core.
Determining the best mattress for you will depend on a few factors, especially choosing between traditional and bed-in-a-box mattresses. Both are supportive enough to accomodate any sleeping position and body type, but they have distinct feels and standout qualities: the Casper offers a softer surface, more closely conforming to the body without too much sinkage. The Saatva has a responsive, supportive feel in all three firmness settings (the level of contouring to the body varies between the Plush Soft, Medium Firm and Luxury Firm options).
Here’s the bottom line: If you sleep hot and are looking for a sophisticated innerspring design at a low price point, go with Saatva. If you like memory foam but don’t want to feel “stuck” in the mattress, go with Casper.

Mattress firmness refers to how soft or firm the bed feels to individual sleepers. Firmness level is most closely tied to a bed’s comfort layer, which typically contains polyfoam, memory foam, latex, or a combination of these materials. Beds are rated on a firmness scale of 1 to 10, with 1 being very soft and 10 being very firm. The best soft mattresses tend to conform very closely to the sleeper’s body, while firm mattresses have thinner comfort layers that minimally conform.
The Casper has a medium level firmness that is well received because it works well for any sleeping position in lightweight or average weight categories. Without being too firm or soft, its cushiony comfort foams and dense polyfoam core provide a nice balance of contouring and support throughout the body.
The Saatva is available in three firmness settings, so its feel will depend on the level you choose. The Plush Soft option will conform very closely and have a soft feel (4/10). The Luxury Firm option will conform to a moderate extent and is most similar to the Casper. The Firm option does not have the soft polyfoam comfort layer and will feel like sleeping “on” the mattress, recommended as the mattress for stomach sleepers who need their hips lifted on top of the mattress.. All three options are more bouncy, similar to a hybrid mattress, because of the coil-on-coil design.
When a person or pet moves in a bed, that motion creates movement that can be felt elsewhere in the mattress. Mattresses that minimize this motion transfer are more desirable for people who wake easily when a partner, pet or co-sleeping child moves around the bed at night.
As a foam mattress, the Casper inherently offers better motion isolation because of the softer, more adaptive foam layers. The Saatva’s coil system gives it more bounce and less motion isolation on its responsive surface.

Regardless of the type of bed, all mattresses are prone to sinking at the edges over time. This is because people tend to spend time on the edges of the bed, whether sleeping or sitting. Innerspring mattresses like the Saatva tend to offer better edge support. It offers a consistent sleep surface that won’t sink at the edges much over time. The Casper has moderate edge support relative to other foam mattresses thanks to its thicker-than-average core, but it may sink at the edges over time.
Pressure relief refers to how closely a mattress conforms to a sleeper’s body to help prevent soreness or pain from developing in pressure points in various sleeping positions (stomach sleepers, back sleepers, side sleepers, combination sleepers). Conforming is often determined by the mattress’ comfort layers, with materials like memory foam providing the best pressure relief.
The Casper offers quality conforming, but heavyweight sleepers may find the bed sags too much for comfort. The Saatva’s coil-on-coil construction is less pressure relieving than the Casper, but its thick comfort layer and Euro pillow top help it relieve pressure to a greater extent than most innerspring mattresses. For more of the best pressure relieving mattresses, see our top picks on the best mattress for side sleepers.
Spinal alignment is determined by a bed’s ability to provide a flat, even surface that will help align the spine and prevent sinking beneath heavier areas of the body. Proper spinal alignment is necessary to combat back pain and support pressure points.
The Casper and Saatva’s ability to align your spine properly will depend primarily upon your weight and sleeping position. Average weight and lightweight sleepers should have the support they need on the Casper and the Plush and Luxury Firm versions of the Saatva. The Casper’s Zoned Support Layer targets the hips and back for pressure relief. Heavyweight sleepers should consider the Firm version of the Saatva mattress for adequate support in all three sleeping positions.
Durability is how long a mattress will perform well throughout its use. Most mattresses last seven or more years before they need to be replaced, and the Saatva and the Casper seem to be on par with this expected lifespan. Both mattresses have strong base layers that will likely lead to similar length in durability.
Temperature neutrality is an essential quality to look for if you sleep hot. Innerspring and hybrid beds tend to have better breathability than foam beds, as foam tends to trap heat. The Casper sleeps cool relative to other foam beds because the top comfort layer is less dense, making it more breathable. The Saatva’s traditional innerspring construction creates excellent airflow, making it one of the cooler mattress options on the market. If cooling is essential to a good night’s sleep for you, we recommend the Saatva. For other cooling mattreses, so our picks for the best mattresses for hot sleepers.

Cover | Polyester blend |
Comfort Layer | 1.5” polyfoam
2” memory foam |
Transitional Layer | 2” memory foam |
Support Layer | 7” high-density polyfoam |
Mattress Thickness | 11” |
The Casper is an all-foam mattress with top layers of polyfoam and memory foam and a support sore of high-density foam. Altogether, the bed measures 11” tall and is roughly a 6/10 on the firmness scale, which is a medium feel that balances support and comfort.
The bed’s cover is a polyester-blend made from recycled materials. It features two comfort layers: a 1.5” layer of standard polyfoam, which gives the bed a light bounce, and a second zoned support layer of memory foam that supports the hips and back while softly contouring to the shoulder. The second layer gives the bed its contouring feel, while the top layer prevents the sleeper’s body from sinking too deeply.
The base layer of the Casper is 7” of high-density polyfoam that stabilizes the bed. The foam layers work to provide a balance of pressure relief, body contouring and support that make it appealing for people who enjoy the comfort of memory foam but don’t like the feeling of sleeping “in” their mattress.
Cover | Euro-top cover (fill varies by firmness setting) |
Comfort Layer | .6” Polyfoam
.4” Memory foam |
Transitional Layer | 4” pocketed coils |
Support Layer | Recycled steel bonnell coils |
Mattress Thickness | 11.5” or 14.5” |
The Saatva is a luxury innerspring mattress with a Euro pillow top, organic cotton cover, and a coil-on-coil support core. It comes in three firmness settings—Plush Soft, Luxury Firm and Firm—and the construction of the mattress varies slightly depending on the firmness level chosen.
All versions of the Saatva include the Euro top, which is intended to make the bed’s surface feel softer. The Plush Soft and Luxury Firm Euro tops contain soft polyfoam, while the Firm Euro top contains firm polyfoam. The added padding is especially beneficial for people who sleep on their sides.
All three versions also feature a polyfoam comfort layer and a second memory foam comfort layer. These are followed by a 4-inch pocketed coil transition layer that’s responsive but not springy. These pocketed coils act as a buffer to prevent sleepers from sinking into the thicker bonnell coils beneath them. The layers of coils make the Saatva exceptionally breathable, give the bed its signature innerspring bounce, prevent sinkage at the edges, and make the bed supportive enough for any body type.

In addition to the sleep trial period, both companies offer a warranty dedicated to covering various defects for a certain amount of time. In line with the industry standard, the Casper 10-year limited warranty covers some indentions, splitting foam and manufacturing defects with the zipper.

The Saatva and the Casper Original are both high-quality beds from reputable companies in the mattress industry. The right one for you will come down to your needs and personal preferences. If you’re heavier, the Saatva will provide better support, but either mattress will work for lightweight or average weight sleepers.
People in these weight categories should consider the type of feel they’re going after and whether they sleep hot. If you like a neutral foam feel and don’t have temperature issues at night, the Casper could work for you. If you sleep hot, prefer a responsive sleeping surface or enjoy luxury add-ons like free White Glove delivery, the Saatva may be the way to go.
