Construction Differences/Notes

  • The Leesa’s LSA 200 and the Casper’s latex-like foam are soft but also very responsive. They allow you to sink in without you getting stuck.
  • The transition layer on the Casper features Zoned Support. This means that it is actually firmer toward the center of the mattress. This makes the mattress feel firmer and more supportive when you are on your back and stomach and softer when you are on your side.
  • The Casper has a nice balance of comfort and support. It 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 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 your sleeping position. The Zoned Support makes it so the mattress feels firmer when you are on your back and stomach and softer when you are on your side.

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

  • Lying on my back, I also feel nice support on the Leesa. However, I would say I prefer the Casper for back sleeping.
  • Side sleeping on the Leesa, I feel fantastic pressure relief. However, 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 I felt in different sleeping positions on the Casper:

  • Back sleeping, I find the Casper to be a good match. 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. The Zoned Support ensures that my hips don’t sink too far into the mattress.

Both mattresses have a balanced foam feel. They are soft but also responsive. You get to sink into the mattress, but you 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.

See more information about Leesa’s firmness and feel in the video below.

Motion Transfer Differences

If you sleep with a partner, it is important to consider how well your mattress handles motion transfer. If your partner moves around on one side of the mattress, will you 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.

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


Now, compare this to the Casper.


Edge Support Differences

If you do sleep with a partner, you should also consider the edge support of your mattress. Will you be able to sit or lie down near the edge of your mattress securely or will you feel like you 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. Neither features the best edge support.

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

Marten’s Take

Marten is a staff writer for us. He 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:

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. However, it is not too much. On my stomach, the mattress is too soft for me. I am bowing in at the hips and getting out of alignment.

I feel better back sleeping on the Casper. 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 you are much heavier than Marten, in the 300-500 lb range, you do run the risk of pressing through the comfort layer on the Leesa and hitting the support layers beneath. You could feel more pressure on your shoulders and hips.

Pick Leesa If…

  • You want a more affordable mattress. While the Leesa costs less than the Casper, it does offer a similar firmness and feel. If you think the Leesa could give you all you need, you could save some money.
  • You are a lightweight back or side sleeper. If you are a smaller person and sleep on your back, the Leesa should be a great match. You should feel enough support for back sleeping and enough comfort for side sleeping. As long as you aren’t too heavy, the Leesa could be a great match.

Pick Casper If…

  • You switch positions at night. The Zoned Support makes the Casper a great fit for all three sleeping positions. When you lie on your back and stomach, the mattress feels firmer and more supportive. When you lie on your side, the mattress feels softer and more comfortable.
  • You are a larger person 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 you are 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 you 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. Heavier people and those who change positions at night should prefer the Casper.
