There are few brands in the mattress world that are bigger and more respected than Casper and Leesa. These two companies have won a hard-earned reputation for creating some of the most comfortable and durable products on the market. They both take pride in utilizing the cutting edge of materials and design technology to provide their customers with the best night’s sleep they possibly can.

One of the most common questions we receive from our readers is about how these two brands compare to one another. They’re both big beasts of the mattress industry and on paper, they seem to be reasonably similar (as they’re both excellent). To further add to the confusion they’re both sold at near identical price points…

Today we are going to settle the question once and for all in our Casper Vs Leesa product review. We’re going to leave no stone unturned and compare the similarities, the differences, and the properties of both mattresses in detail before attempting to make a final recommendation.

Let’s get started.

Big Reveal
Our Hands Down Winner is…
The Casper Mattress

Disclaimer: This is a completely impartial review, we’re not being paid or compensated by either Casper or Leesa to write positively about them.


Let’s start off by taking a look at some of the similarities between the two products (of which there are many).

  • Memory Foam Products – Both products heavily use memory foam in their design for its contouring, supportive properties
  • Cooling Memory Foam – Both products utilize advanced kinds of memory foam to remove the overheating issues commonly associated with the material
  • Price – With a few small exceptions for smaller sized mattresses, both products are almost identically priced
  • Quality – Both the Leesa and the Casper are premium products (with premium price tags), they’re durable, well made, and come with long warranties.


To be honest there are very few differences between the Casper and the Leesa that make a huge difference to the overall sleeping experience (with one exception). If we’re being picky here are some of the main ones.

  • Cooling Methods – The Avena foam top layer of the Leesa and the open cell memory foam top layer of the Casper utilize different methods for creating ventilation within the foam (but both are effective)
  • Layers – While both products are hybrid mattresses made from several different materials the Casper has more layers (4) than the Leesa (3)
  • Construction Method – The Leesa has the same materials in each layer running the entire length of the sleeping surface. The Casper has softer foam towards the head and neck and has more supportive firmer foam towards the hips.
  • Firmness – To be totally honest both the Casper and the Leesa are medium-firm products, there’s not a lot of difference between them (but the Casper is very slightly firmer).

Construction Comparison

So let’s start with the most obvious comparison – the construction of the mattresses. There are several similarities between the design two products, but also some noticeable differences.

Leesa Construction

The Leesa mattress is a hybrid product that combines 3 layers of different materials to provide a sleeping experience that is greater than the sum of its parts.

The top layer is made from Leesa’s famous and patented Avena foam. It’s a material that has been specifically designed to mimic the contouring benefits of memory foam without any of the common issues associated with the material (mainly overheating). It’s an exceptionally cool layer that’s got excellent thermal regulation properties compared to standard memory foam. It’s supportive, reasonably soft, and is pretty much the definition of a perfect top layer.

The second layer in the Leesa is a little thicker than the top Avena foam layer and is made from high quality (but otherwise unremarkable) memory foam. It’s exceptionally supportive, removes pressure points and contours a little more than the Avena foam, which makes it the perfect complement. These two layers combined are what provide the bulk of the exceptional comfort that the Leesa is famous for.

The bottom layer of the Leesa is a super thick 15cm slab of high-density support foam. Again there’s nothing too special about this layer apart from the quality and durability of the foam that has been used. It provides the perfect amount of support and firmness for the softer contouring memory foam layers above (without becoming too firm for most people’s tastes).

The whole product is then wrapped in a stylish, breathable, and hypoallergenic cover in Leesa’s iconic stripe pattern. It’s again a reasonably standard cover for a premium product, but it’s super soft at the very least.

Casper Construction

While the Casper takes a similar multi-material hybrid approach to mattress design, there are some differences compared to the Leesa. The main difference is that it’s a quad-layer product as opposed to the tri-layer design of the Leesa.

The top layer of the Casper is a premium layer of open cell memory foam. Open cell memory foam is considered to be one of the best kinds of memory foam in terms of heat dissipation. Memory foam is traditionally made up of countless individual small enclosed pockets (or cells) of air. This is what gives it its contouring properties, but it’s also what gives it its notorious reputation for overheating.

Because in traditional memory foam the cells are entirely closed the air inside cannot move around and then heats up throughout the night. This creates hotspots underneath the sleeper and can be very uncomfortable.

By opening the cells at one side the air inside them can move around throughout the foam freely. This distributes the heat evenly throughout the mattress and also allows some to be dissipated into the bedroom through ventilation.

The second layer in the Casper is a wedge of high-density memory foam. It provides the exceptional levels of support that the Casper is famous for and is very durable. It’s a reasonably thin layer which means the mattress does not become too firm (which can be a problem in lower quality products).

The next layer down is what Casper calls “transition foam”, but in all honesty, there’s nothing special about this layer except the name. It’s a layer of medium firmness comfort foam that you’d be able to find in any mattress of a similar quality.

The final layer is very similar to the Leesa and is a thick wedge of high-density support foam. Again it’s pretty standard yet high-quality stuff that does the job of providing support without making the overall firmness too hard.

An interesting point to note about the Casper is the zoned support sections (which is something the Leesa does not have). When you lay down on your mattress different amounts of pressure are applied to different parts of your body in different places. Where these pressure points are change slightly depending on your sleeping position, but either way, some points will have more pressure than others.

To account for this the Casper has a zoned construction method that provides softer foam towards the top of the mattress where your neck and shoulders are and firmer foam towards the hips. This innovative construction method provides softness and support where you need it, instead of the one size fits all approach other mattresses take (this includes the Leesa).

The entire product is finally wrapped in a removable and washable soft knit cover which does the job but is again unremarkable.

Firmness Comparison

To be totally honest the firmness levels of both the Leesa and the Casper are reasonably similar. They’re both considered to be medium-firm products, which is what the vast majority of consumers seem to want.

If we were being picky (and we are) the Casper is probably a little bit firmer than the Leesa, but there’s not a whole lot of difference between them in all honesty. If you like a medium-firm mattress, then you’re going to love either product.

Price Comparison

Leesa and Casper are no strangers to one another, they are well known as being two fierce competitors fighting for customers of the exact same demographics. As such, their prices are very tightly aligned (but there are some differences based on size).

  • The Leesa is slightly cheaper than the Casper for a twin ($525 vs $595)
  • The Casper is slightly cheaper than the Leesa for a twin XL ($645 vs $695)
  • The Leesa is slightly cheaper than the Casper for a full ($855 vs $895)

Both Leesa’s and Casper’s queen, king, and California king sized products are the exact same price ($995, $1,195, $1,195)

Which Bed Sleeps Cooler?

Both products are well known for providing exceptionally cool sleeping surfaces, despite mainly being made from memory foam.

Both products top layers are directly responsible for their cooling properties. The configuration of the Avena foam in the Leesa and the open cell memory foam in the Casper both provide excellent ventilation – albeit in slightly different ways.

Reportedly the Casper provides a cooler sleeping surface than the Leesa because of the open cell foam, but quite honestly the difference is negligible. It’s like asking if a Ferrari or a Lamborghini is faster – one may be quicker than the other, but either way, they’re both super duper fast…

Which Bed Would Be Best For A Side Sleeper

There’s finally a clear winner in this section – the Casper.

The zoned construction method we talked about earlier has been mainly designed for side sleepers (although it’s great for all positions to be honest). The softer foam that is located towards the head and shoulders allows for side sleepers to sink in a little at the top of the mattress. Similarly, the firmer section towards the hips allows for support where side sleepers need it most.

This isn’t to say that the Leesa is a bad mattress for side sleepers, it’s still an exceptional product – but the Casper is definitely better.

Should I buy a Casper or Leesa Bed?

To be totally honest, this is one of the hardest calls we’ve had to make on this site. Both the Casper and the Leesa are exceptional products and both are nearly identically priced.

We love the construction quality of the Leesa and the materials that have been used. The Avena foam top layer is exceptionally comfortable and works in perfect harmony with the memory foam and high-density foam layers below. It’s a product that is in perfect balance with itself and is hands down one of the best sleeping surfaces on the planet.

That being said, we also love the Casper too. The quad layer design provides a range of properties which add up to give an exceptionally comfortable night’s sleep. Additionally, the open cell memory foam top layer provides pretty much the most efficient thermal regulation it’s possible to have from memory foam.

If we had to pick a winner (and we do), we’d pick…..

The Casper.

It’s an extremely close call, but the zoned construction method is one of the most innovative design patterns we’ve ever seen in the mattress world.

It provides such impressive results (and is such an obviously effective idea) that it makes us question all other mattresses that use the same density and material across their entire surface. The amount of pressure applied to the mattress varies massively from your head to your hips, so why on earth should you have the same “one size fits all” material across the entire surface.

There is no way that this design pattern has gone unnoticed by other manufacturers (including Leesa). It provides comfort and support at levels that we quite frankly have never seen before in another mattress. We highly suspect other products to be released by Casper’s competitors in the near future to feature a similar zoned construction method.


While we have chosen the Casper as our overall pick, it was a very close call. The Leesa is a truly exceptional product that is more than worthy of your consideration. We highly doubt that you would be the slightest bit disappointed if you ordered one.

But, when push comes to shove, we think that the Casper is the better product, and because the price of both mattresses is practically identical – we highly recommend it.
