In this review, we’ll be sizing up two of the most popular mattresses on the market: the Casper and Leesa. Though both beds are built entirely of foam, they use the materials in different ways to achieve two totally distinct feels. But the question remains… which feel is right for you?
Well folks, that’s what we’re here to find out. I’m going to compare and contrast every aspect of these two models, from their divergent constructions all the way to their unique feel profiles. Curious to see which mattress reigns supreme? Then you better keep reading below for my Casper vs Leesa review!
Memory foam feel – The Casper and the Leesa both use memory foam for its classic feel of sinkage and body-contouring. They both play up its comforting properties while reducing its tendency to trap body heat by putting a layer between the sleeper and the memory foam layer.
Bounce – Although these mattresses don’t have the bounce of a traditional innerspring mattress, they do both retain more mobility and springiness than the stereotypical all-foam mattress.
Polyester cover – Both beds use thin polyester covers to keep the mattress cool to the touch. Polyester is known as a breathable fabric that helps draw heat away from the sleeper.
What are These Beds Made of?
Now that you know what makes the Casper and the Leesa similar, I want to move into what makes them different from each other. Let’s pull back each layer to see the construction of each mattress in a detailed way, starting with the Casper.
Cover – As mentioned above, the Casper starts off with a thin polyester cover. It is a breathable material that is relatively common in all-foam beds.
Comfort – Below the polyester cover, the Casper contains a soft open-cell foam that allows the sleeper to sink right into the layer. Even with all this give, open cell foam tends to retain its breathability, helping the Casper sleep cool.
Contour – After the open cell foam, a layer of memory foam provides contouring around the body and a feeling of sinking even further into the mattress. Memory foam tends to trap body heat, but the open-cell foam between this layer and the sleeper reduces this effect.
Transition – Moving past the memory foam layer, there is a transition layer of slightly firmer poly foam. This is a layer that is zoned for support and lift in the hips while providing pressure relief in the shoulders (the foam is firmer at the hips and softer in the shoulders), a feature that helps to keep the spine aligned for side sleepers.
Base – Finally, the base of the Casper comes from its layer of high-density poly foam. This is a firm layer that provides support to the softer layers above it and to the sleeper as well.
Thoughts: The Casper is made to provide plenty of contouring and sinkage on first contact. Combo sleepers will probably enjoy the added pressure relief in the shoulders from the zoned transition layer. The zoning allows the Casper to relax the shoulder joints while maintaining hip support for good spinal alignment.
Cover – Like the Casper, the Leesa also starts off with a polyester cover. It is a little thicker than the Casper cover, but remains breathable while providing a cozy feeling.
Comfort – Underneath the polyester cover, the Leesa contains a proprietary latex alternative foam known as “LSA 200.” It’s a poly foam that provides a quick response to pressure and sleeps cool.
Transition – The LSA 200 foam overlays a section of memory foam, just like in the Casper. The end result is a comfortable sink into the mattress and good pressure relief in sensitive areas without allowing the memory foam to trap body heat (as it is prone to do on its own) or produce too much sinkage.
Base – The fundamental support of the Leesa comes from a layer of high-density poly foam. This is the same type of foundational material as in the Casper, and it is fairly common for all-foam mattresses as a support base.
Thoughts: The Leesa provides pressure relief in the form of its proprietary LSA 200 foam. Its aerated, soft top layers allow a comfortable sinkage while also sleeping cool. Back sleepers should find a lot about this mattress to like, because it provides a good mix of comfort and support in the hips for spinal alignment.
Casper vs. Leesa
Now that you know what is inside each bed, let’s put the Casper and the Leesa head to head. How do these two mattresses match up when they are compared directly? Let’s find out!
The soft open cell layer of the Casper allows for lots of sink right into the memory foam layer of the mattress. Still, its support layers provide support in sensitive areas like the hips. This mix of features should work well for combo sleepers, especially with the zoned support that helps keep good spinal alignment in the side position. Strict stomach sleepers may need a slightly firmer mattress for hip support.
The Leesa provides a slightly firmer feel that provides good support for the hips in the back and stomach positions. Although it does not have the bounce back of a traditional innerspring , it does have good mobility that allows sleepers to feel on top of the mattress and switch positions without much trouble. Strict back sleepers especially should love the support that helps to align the spine, but strict side sleepers may find the mattress too firm in the shoulder joint.
Although the Leesa is slightly firmer than the Casper, strict stomach sleepers may need something firmer than either of these beds can offer. The memory foam layers in both mattresses allow the sleeper to sink down quite a bit, which could end up causing the back to bow uncomfortably over the course of a night. Back and combo sleepers have a personal choice to make — go with the contouring feeling of the Casper or the “on top” feeling of the Leesa.
Which Mattress Has the Best Feel?
Now that we have looked over the differences in the construction of the Casper and Leesa, it’s time to see how these mattresses really feel. Even subtle differences can cause two products to feel quite unique from each other.
I usually test a mattress for firmness first because of its importance to the overall feel. My firmness scale ranges from 1 (soft) to 10 (hard). On this scale, 6.5 (not 5.0) is the industry standard for medium firmness. I test for firmness alongside colleagues of different body shapes and sizes. The number you see below is our average firmness rating.
I gave the Casper a 6.5/10 on the firmness scale, which means that this mattress is right in line with the industry standard for medium firmness. The zoned transition layer of poly foam adds another dimension to this rating, however. Medium firmness is often too firm for strict side sleepers without added pressure relief in the shoulder joint. More sink in the shoulder is exactly what the Casper provides, so side sleepers enjoy a mix of support and relief that works well for spinal alignment and comfort in the side position.
Overall, the Casper has a balanced feel that should attract sleepers who switch positions often during the night. Because of the mix between pressure relief and support in sensitive areas, combo sleepers can find comfort in different positions. The mobility is not as good as a hybrid, but it isn’t difficult to move around. Also, strict stomach sleepers may find the sink in the open cell foam and memory foam too be a bit too much in the hips.
The Leesa firmness rating came out as a 7/10. This means the Leesa is slightly firmer than the industry standard, providing good spinal alignment for strict back sleepers. Combo sleepers get good mobility from the LSA 200 foam comfort layer, but as a result, the Leesa loses a bit of the contouring feel of memory foam.
Combo-side sleepers should be ok on the Leesa, but strict side sleepers may find they get “joint jam” in the shoulders during the night. Combo-stomach sleepers should also be fine, but strict stomach sleepers may not find the hip support in the Leesa adequate for a full night. In short, if you are looking for a firmer feel and you don’t necessarily want that classic memory foam sink, the Leesa may be for you.
The Casper and the Leesa both feature memory foam in the same context i.e. to provide a bit of pressure relief while trapping less body heat. The LSA 200 foam of the Leesa ends up feeling a bit firmer than the open-cell foam of the Casper comfort layer. The result is a distinct feel for each mattress — classic memory foam sink for the Casper, and a firmer, more mobile feel for the Leesa.
Both Casper and Leesa have hybrid alternatives, and the Casper adds an Essential and Wave option for added value or luxury. Let’s compare the company namesakes to their mattress siblings to make sure you’re making the most informed decision possible.
- The Casper Essential ($395-$795) is the company’s value option and has an overall firmer feel than the Original Casper.
- That being said, it will likely work best for strict back and stomach sleepers who need support for spinal alignment.
- For more on the Casper Essential, check out my full review.
- The Wave ($1345-$2995) is the company’s luxury product as its five-layer design provides a soft, plush feel.
- This gentle construction produces a lot of pressure relief at the shoulders and hips, which could be a big plus for side sleepers.
- Check out my full review of the Casper Wave!
- Both the Casper and Casper Wave models have hybrid counter parts, which feature pocketed coils in addition to the foam layers present in the original mattresses.
- Click here for more on either the Casper Hybrid or Casper Wave Hybrid.
- The comfort foams in the Lessa Hybrid are similar to the all-foam Leesa, but the hybrid has added coil support.
- These coils add a bit more mobility and springiness that makes it a good choice for combo sleepers. Great edge support and motion isolation also provide attractive advantages for couples.
- The Leesa hybrid is more expensive ($1095-$1895) than the original Leesa ($595-$1195).

Which Mattress is the Winner?
Our comparison of the Casper and the Leesa is almost at an end. I have gone over both beds’ constructions and feels as well as discussed the important differences between them. No one can say which one is your personal winner, but I can summarize the major points to help you make a smart decision.
If you like the feeling of sinking into your mattress for a good night’s sleep, then the Casper may fit you better than the Leesa. The Casper’s zoned support is great news for side sleepers who might otherwise get jammed up in the shoulder area. This mattress isn’t very bouncy, but it is still mobile enough for combo sleepers to switch positions easily. Stomach sleepers may need something firmer for hip support.
The Leesa gives a slightly firmer feel for sleepers who prefer not to sink into the mattress. This firmness may be a bit much for side sleepers because of the lack of pressure relief in the shoulder area. However, strict back sleepers and combo sleepers who like a supportive mattress should find a lot to like here, especially since the LSA 200 foam helps the Leesa sleep cool as well.
The Casper and the Leesa both feature 100-night trial periods and 10 year warranties. Shipping for both mattresses is free. The price range of both mattresses is also similar, with both coming in between $595-$1195 from Twin to King.
And finally, here are my biggest takeaways from the Casper and Leesa mattress comparison. If you are on the fence about which one to get, this should help tip you one way or the other!
- Strict side sleepers should enjoy the zoned support of the Casper’s transition layer. It provides more pressure relief in the sensitive shoulder area.
- The Casper has a balanced feel that should work well for combo sleepers, because its mix of support and pressure relief change with the sleeper’s position.
The memory foam, latex, and heavy-duty poly foam work together to offer sleepers a beautifully balanced feel!
- Strict back sleepers should enjoy the supportive nature of this mattress in the hips.
- If you are looking for a mattress that sleeps cool, the construction of the Leesa tends to draw heat away from the sleepers even with its layer of memory foam.
Made from a blend of proprietary foam, memory foam, and high-density poly foam, the Leesa Mattress offers a softly balanced feel that's great for a wide range of sleepers.
