Casper and Leesa are two incredibly popular foam mattresses that have really transformed the mattress industry.  We get tons of emails asking us to compare the two mattresses, so I thought I would add my opinion to the debate.  There are certainly a lot of similarities between the two mattresses, but I’ll try to highlight some differences to help you make a better decision.

Key Similarities

  • Both are all foam mattresses
  • Both use latex-like foam over memory foam in the comfort layer
  • Both are breathable mattresses
  • Both mattresses have some bounce
  • Both have a similar firmness level
  • Both are from well established / respected companies
  • Prices are almost the exact same

Key Differences

  • Leesa has a comfort layer that is one inch thicker than the Casper
  • You sink into the Leesa slightly more (because of the thicker comfort layer)
  • The Casper Queen weighs about 12 lbs. more than the Leesa

Casper Construction

The picture below shows the four separate layers of the Casper.  Here’s a breakdown:

  • The top layer is 1.5 inches of a high-density specialty poly foam layer that is latex-like in its properties.  It is open-celled (meaning it’s breathable), durable, and has good bounce.
  • The second layer is 1.5 inches of 3.5 lb. density memory foam.  This layer adds great pressure relief to the mattress.
  • The next layer is 1.5 inches of 2.5 lb. density poly foam.  This layer helps ease the transition from the comfort layers to the support layer, which is especially important for heavier sleepers who might push through the comfort layers.
  • The final layer is a 5 inch layer of 1.8 lb. density polyfoam (same density as the Leesa support layer).

Leesa Construction

The picture below shows off the different layers of the Leesa.  Here is a breakdown:

  • The first layer is Aveena foam.  It’s a latex-like foam that is breathable (check out the pinholes), bouncy, and highly durable.  It has similar properties to the top Casper layer.
  • The second layer is 3.0 lb. density memory foam, which provides great pressure relief and conforming support.
  • The base layer is a 1.8 lb. density poly foam (same density as the Casper base layer).

Construction Differences/Notes

  • The Leesa is 10 inches thick, while the Casper is 9.5 inches thick
  • The Leesa has a 4 inch comfort layer.  The Casper has a 3 inch comfort layer, but it has a 1.5 inch transition layer
  • Overall, Casper uses higher-density foams than Leesa does (Casper is .5 inches thinner but a Queen weighs 12 lbs. more than the Leesa Queen).
  • Both mattresses should be about equal in terms of breathability

Firmness/Feel Differences

I go back and forth trying to decide which of the two mattresses is firmer.  I’ve had several people lay on both and about half have said the Casper is firmer and half have said the Leesa is firmer.  I personally now think the Casper is very slightly firmer, but I want to reiterate that it is very close.

Motion Transfer Differences

You can see from the videos below that both mattresses do pretty well with motion isolation and can be a good choice for couples.  They are very close, so for this I can’t say that one is better than the other.

What Should You Base Your Decision On?

  • Slight Feel Difference– The difference in feel is slight.  I think because of the thicker comfort layer, you sink into the Leesa just a little bit more, whereas the Casper has a slightly more “on” the mattress feel
  • Just Go With Your Gut– You can see that there are major similarities between the two mattresses and the differences are very subtle.  They are both great mattresses, so I think you should just go with your gut.

Hopefully I’ve been able to go over the main points of difference between the mattresses enough for you to make sure.  If you have any other questions, don’t hesitate to leave a comment.

6 thoughts on “Leesa Vs Casper- Which Should You Choose?”

  1. I know Casper has updated the mattress to include “zoned support”. When you did this mattress review/comparison, was it the new Casper with the zoned support?

  2. Do either of these mattresses get that “Mrs. Bates” depression, as in Alfred Hitchcock’s Psycho movie, or does the mattress retain its level flatness allowing no depression to show when looking at a bed that has been made up?

  3. Out of these 2 mattress, which one would keep me cooler? I’m always hot so when I sleep my memory foam on my mattress keeps me hot. Once I move it does cool down but would like something that will absorb the heat. Thanks
