At first, it appears as if the mattresses have a lot of similarities, but upon a closer look they have some noticeable differences consumers should be aware of.  This comparison will go through the construction of both mattresses in detail and highlight the main takeaways people should know about before buying one of them.

  • They have a very similar construction, with a latex-like layer over memory foam.
  • They are similar in terms of overall firmness.

Key Differences

  • The Leesa is more affordable than the Casper by a small amount.

Leesa Construction

  • The Leesa is 10” tall and features three separate foam layers.
  • The cover is soft and has a sweatshirt feel that doesn’t affect the overall feel of the mattress signficantly.
  • First, there are 2” of a proprietary foam, LSA 200, which provides softness, pressure relief, and bounce.
  • Next, there are 2” of memory foam, which gives the mattress great pressure relief and body contouring.
  • Finally, the base is 6” of polyfoam, which is a pretty standard base layer for an all-foam mattress.

Casper Construction

  • The Casper is 12” tall and features four distinct foam layers.
  • The cover is soft and thin and doesn’t affect the feel of the mattress too much.
  • The first layer of the Casper is 1.5” of a latex-like foam which gives the mattress some responsiveness.
  • Below this is 1.5” of faster-responding memory foam, which gives the mattress great pressure relief and body contouring.
  • The next layer is 1.5” of transition foam with Zoned Support, which means it is firmer in the middle and softer underneath the shoulder area.
  • The base layer is 7” of a durable support foam, which is a pretty standard layer on the market.

Construction Differences/Notes

  • The Leesa’s LSA 200 and the Casper’s latex-like foam are soft but also very responsive, which allows people to sink in without them getting stuck.
  • The transition layer on the Casper features Zoned Support, which means that it is actually firmer toward the center of the mattress. This makes the mattress feel firmer and more supportive when people are on their back and stomach and softer when they are on their side.
  • The Casper has a nice balance of comfort and support, which could be a better fit for combination sleepers and those who switch positions at night.
  • The Casper is thicker and, also considering the Zoned Support, it should be a more supportive mattress. This means it could potentially be a better fit for heavier people.

Firmness/Feel Differences

In terms of firmness, I thought the Leesa felt like a 6.5/10 and the Casper felt like a 6/10. However, the Casper will feel different depending on one’s sleeping position. The Zoned Support makes it so the mattress feels firmer when people are on their back and stomach and softer when they are on their side.

Here is how it felt in different sleeping positions on the Leesa:

  • Lying on my back, I also feel nice support on the Leesa, but I would say I prefer the Casper for back sleeping.
  • Side sleeping on the Leesa, I feel fantastic pressure relief, but I would say it is about equal to what I feel on the Casper.
  • On my stomach, the mattress is too soft for me. Without the Zoned Support, I am not getting quite enough support on my hips.

Here is how it felt in different sleeping positions on the Casper:

  • Back sleeping, I find the Casper to be a good match, as my hips sink in the right amount, and the Zoned Support helps support my lumbar area.
  • On my side, the Casper is also a nice match. The mattress is actually softer under my shoulder area so I feel some great pressure relief there.
  • Moving to my stomach, the Casper is properly supportive, as the Zoned Support ensures that the hips don’t sink too far into the mattress.

Both mattresses have a balanced foam feel that is soft but also responsive. People get to sink into the mattress, but they should still be able to move around easily.

Again, the Casper might feel a bit different because of its Zoned Support. It will feel firmer toward the center of the mattress and softer to the other ends.

Motion Transfer Differences

If someone sleeps with a partner, it is important to consider how well their mattress handles motion transfer. If their partner moves around on one side of the mattress, will they feel that motion or not?

To test out the motion transfer on these two mattresses, I first placed a glass of water on top of each mattress. Pressing into the surrounding areas, I saw little disturbance on both mattresses. Also, I lay down on both mattresses and asked Marten to move around on the other side. I felt very few of his movements.

Both mattresses handle motion transfer well and could be a good match for couples who don’t want to be disturbed by their partner’s movements.

See how the Leesa deals with motion transfer in the video below.

Now, compare this to the Casper’s motion transfer with the video below.

Edge Support Differences

If someone does sleep with a partner, they should also consider the edge support of their mattress. Will they be able to sit or lie down near the edge of their mattress securely or will they feel like they are going to fall off?

Sitting down on the edge of these mattresses, they do collapse quite a bit. Because of this, I don’t feel very secure. Also, when I lie down near the edge of both mattresses, I feel somewhat like I might roll off.

The mattresses are about equal in terms of edge support, and frankly neither features the best edge support.

People can see the Leesa and Casper’s edge support in the photos below.

Marten’s Take

Marten is a staff writer for us and has a much different body type than me: He is 6’7″ and weighs about 230 lb; I am 5’9″ and 160 lb. Here is what he thought about these mattresses and how appropriate they are for heavier sleepers:

I felt like the Leesa was a 6.5/10, and the Casper was a 6.5 or 7/10.

Back sleeping on the Leesa, my hips sink in the right amount, and I feel nice support overall. When I move to my side, I feel a bit of pressure on my shoulders and hips, but it is not too much. On my stomach, the mattress is too soft for me, as I am bowing in at the hips and getting out of alignment.

I feel better back sleeping on the Casper, as the Zoned Support gives me nice lumbar support, and my hips don’t sink in too far. While I do feel some pressure relief on my side, it is not as much as I felt on the Leesa. When I move to my stomach, I feel better support than I felt on the Leesa.

Heavier back and stomach sleepers should probably go with the Casper. Heavier side sleepers might prefer the Leesa.

I do believe that the Casper is a better match for heavier people, so I was not surprised that Marten felt better support back and stomach sleeping on the Casper. While Marten felt better pressure relief on the Leesa, I would say if someone is much heavier than Marten, in the 300-500 lb range, they do run the risk of pressing through the comfort layer on the Leesa and hitting the support layers beneath. People could feel more pressure on their shoulders and hips.

Who Should Pick Leesa…

  • Those who want a more affordable mattress- While the Leesa costs less than the Casper, it does offer a similar firmness and feel. If someone thinks the Leesa could give them all they need, they could save some money.
  • Lightweight back or side sleepers- If someone is a smaller person and sleeps on their back, the Leesa should be a great match. They should feel enough support for back sleeping and enough comfort for side sleeping. As long as someone isn’t too heavy, the Leesa could be a great match.

Who Should Pick Casper…

  • People who switch positions at night- The Zoned Support makes the Casper a great fit for all three sleeping positions. When someone lies on their back and stomach, the mattress feels firmer and more supportive. When someone lies on their side, the mattress feels softer and more comfortable.
  • Those who are larger or need more support- The Casper is also more supportive than the Leesa. The Zoned Support means that larger people should feel better support, especially when they are on their back and stomach. If someone is heavier or just want a more supportive mattress, the Casper should be the way to go.

While the Casper and Leesa may appear similar at first, there are some noticeable differences. If people consider the information above, it shouldn’t be too difficult to choose between these two mattresses. Lightweight back and side sleepers, as well as those who want to spend less money, should take a look at the Leesa, while heavier people and those who change positions at night should prefer the Casper.
