The bed is designed with a three-layer comfort system, is medium in firmness, and has become one of the most well-known and popular all-foam mattresses today. Leesa, ironically, was also founded in 2014 and brought the Leesa Original to market as its first product. This all-foam mattress with a medium feel is known for offering a balance of cushioning and support.

Casper Construction

The Casper Original is a mixed-foam mattress that’s made with comfort layers, a transitional layer, and a supportive core layer. In the comfort portion, which is three layers thick, 1.5 inches of standard memory foam, 1.5 inches of 4 PCF memory foam, and 1.5 inches of 2 PCF polyfoam create a slightly bouncy feel with excellent body-contouring. The transitional layer contains 1.5 inches of 2.5 PCF polyfoam, which helps prevent too much sinkage to the dense base layer. This layer also has zoned support, meaning it feels firmer beneath the shoulders than the back and legs.

The support foam layer of the Casper contains 7.5 inches of 1.8 PCF polyfoam, which stabilizes the bed and prevents the top two layers from sagging. This support layer also reinforces the edges to make it easier to get in and out of bed. In total, the mattress measures 12 inches high, which is relatively thick for a mixed-foam mattress. This aids in the mattress’s ability to provide above-average cushioning when compared to other all-foam models.

The foam layers are encased in a removable polyester cover for easy washing. It’s also exceptionally light at 71 pounds in a Queen size, which makes it easy to move and rotate as needed. In general, foam construction provides a nice combination of support, body contouring, and motion isolation.

Leesa Construction

The Leesa is an all-foam mattress that consists of just two layers. The top layer contains 2 inches of 3 PCF polyfoam and 2 inches of 3 PCF memory foam. The 3 PCF polyfoam gives the mattress a moderate firmness, and the bottom layer gives it a soft feel to the touch. These layers also work together to create moderate body-conforming for pressure points in the back, hips, and shoulders.

Beneath the comfort layer is a support core made from 6 inches of 1.8 PCF HD polyfoam, which helps reinforce the mattress, prevent sagging, and maintain the medium-firm feel. The Leesa also weighs 71 pounds in a Queen size and is fairly easy to move. The layers of foam are encased in a polyester and lycra blend cover that is soft, breathable, and durable. 

Things to Consider When Picking A Mattress

Firmness / Feel—Both mattresses are a 6/10 on the firmness scale, meaning that they are medium firm. This middle-of-the-road firmness means they could be appropriate for any sleeping position, depending on your body weight and preferences. They do, however, differ slightly in feel. The Casper provides close-body conforming with a supportive feel, whereas the Leesa provides a body-hugging feel that makes you feel like you’re sleeping “in” the bed rather than “on” it. Both mattresses are best suited for sleepers under 230 pounds.

Motion Isolation—If you’re sleeping with a partner or a pet, motion transfer is an essential quality to consider. Both the Leesa and the Casper excel in motion isolation, and neither makes any noise. Their dense, multi-layered foam constructions cut down on motion transfer significantly.

Edge Support—Edge support is typically evaluated by sitting on the perimeter of the mattress and acting as though one is getting in or out of bed. Edge support is important for individuals who are aging, have disabilities, or endure chronic pain. Unfortunately, both the Leesa and the Casper rank poor to fair in edge support. Both have noticeable sinkage at the edges of the mattress, which is typical of all-foam models.

Pressure Relief—Pressure relief refers to a mattress’s ability to alleviate pressure in sensitive areas of the body such as the shoulders and hips. The Leesa conforms closely to the body, resulting in excellent pressure relief. The Casper also provides nice pressure relief for lightweight and average weight sleepers. As mentioned above, neither mattress would provide pressure relief for heavy individuals. 

Spine Alignment—Spinal alignment refers to how properly aligned the spine is when a sleeper is resting in their sleeping position of choice on a mattress. The Casper supports side sleepers, back sleepers, and stomach sleepers who are lightweight exceptionally well because it provides sufficient cushioning beneath the shoulders and hips and above-average support throughout the mattress, respectively. Average weight sleepers will experience the same. The Casper offers the same spine alignment benefits. This similarity between the two mattresses is due to their medium firmness levels, which provide a balance of contouring and support for sleepers in almost any sleeping position.

Durability—Both the Leesa and Casper are relatively new-to-the-market mattresses (2014), so it’s too soon to say with confidence how durable these mattresses are in the long-run. However, mattress reviews note that both mattresses last roughly six to eight years, which is on-par for other all-foam and mixed-foam mattresses in this price category.

Temperature Neutrality—As a primer, it’s important to understand that all-foam and mixed-foam mattresses tend to trap heat more than other mattress types. The Leesa and Casper are no exception, and the polyfoam and memory foam in their materials tend to sleep warmer than hybrid or innerspring models, for example. However, overall the mattresses will sleep neutral (not cool) compared to other all-foam models. Their comfort layers do trap some heat but have above-average breathability when compared to other foams.

Other Models Available

Casper EssentialThe Casper Essential is the most basic of the Casper mattresses. It is comprised of 3 layers of open-cell foam with a soft feel and a balance of support and comfort. 

Casper WaveThe Casper Wave combines foam and latex, and it’s marketed as a luxury mattress with a higher price-point. It has a medium-soft feel but absorbs slightly more body heat than the Original Casper. 

Casper Hybrids— The Casper Hybrid mimics the construction of the Casper Original but replaces the high-density foam core with pocketed coils, which improve breathability and provide more bounce.

Leesa Hybrid— The Leesa Hybrid has a slightly firmer feel and contains polyfoam and memory foam like the Leesa original but has a pocketed coil core. It’s more responsive than the original Leesa and is more supportive of the two models.

Leesa Legend– The Leesa Legend is the newest product, equipped with a dual pocket spring system to provide support and comfort to sleepers.

Conclusion 

Both of these mixed-foam model beds contain high-quality materials, are thoughtfully constructed, have similar price points, and work well for sleepers of all types in the average weight and lightweight body categories. The devil is in the details when it comes to choosing between the two mattresses. The Casper, for example, is taller in height than the Leesa, and the thicker profile can aid in overall support. The Casper also provides more targeted pressure relief, thanks to its zoned layers, which is why we recommend it for sleepers with aches and pains. It is, however, the more expensive of the two models, so if you don’t suffer from chronic pain, the Leesa is a better option for cost savings.
