2014 was a big year for the mattress industry. Several new mattress start-ups, selling online only, are dramatically re-shaping the industry. With so many factory direct online options available, it’s as difficult to know the best option online as it is in store. Two of the most talked about options are the Casper and the Leesa mattresses. Both are hybrid foam mattresses, both have a great price point, and both have exceptional reviews. But there are important differences, so with that said, let’s dive in!

Unfortunately, Casper does not provide any coupons for Sleepopolis readers.


Both Casper Sleep and Leesa Sleep mattresses are hybrid foam mattresses, meaning they use a combination of different types of foam to achieve optimal comfort and support. Hybrids are designed to offer great support from memory foam and great comfort / cooling, provided by a layer of Latex or Avena foam.

Foam Layers

Casper uses 3 foam layers. The top layer is a 1.5 inches of latex foam. The middle layer is 1.5 inches of memory foam. The bottom layer is a 7 inch support foam base. Latex foam is ideal for providing airflow and cooling throughout the night, which helps prevent the mattress from sleeping too hot. I slept on my Casper for 3 months and never once felt like it slept any hotter than my old innerspring mattress.

Leesa uses 3 foam layers also. The top layer is 2 inches of Avena foam. Avena foam is a latex foam alternative and is designed to feel and sleep just like latex. However, Avena foam does provide better durability than latex foam (read our Avena vs. Latex comparison post here for more information). The middle layer is 2 inches of memory foam. The bottom layer is a 6 inch support foam base. Leesa’s top layer of Avena foam is designed to provide cooling and airflow throughout the night, so the mattress doesn’t “sleep hot”. Like the Casper, I never felt like the Leesa slept hot in the slightest.

After sleeping several months on each mattress I would say both mattresses are fairly comparable in terms of cooling. I haven’t felt like they are any hotter than any innerspring mattress I’ve slept on.


The cover is not something that’s particularly important from a pure functionality standpoint. However, it does make a nice statement about each mattress.

Casper has gone with a more subtle and traditional cover. The cover is 2-tone, with all white on top and grey around the sides. The white piece of fabric on top is fairly thin, stretchy, and porous. This makes it great from a breathability and cooling perspective, however I would caution you to be careful when moving the mattress. Because it is so porous it’s more susceptible to damage. I accidentally tore a few threads out last time I was moving my Casper.

Leesa’s cover utilizes a bold 4-bar design. The cover is cut from a single piece of fabric and woven together so it’s almost entirely seamless. Leesa’s cover is quite unique compared to most other mattresses in its seamless construction and design. I really love the aesthetic design of the Leesa.

Leesa’s cover is built from a blend of polyester and lycra. Polyester provides great durability, protecting the Leesa from damage, while the lycra provides exceptional stretch and breathability. Lycra is the same material they use to make performance sports clothing.

In terms of firmness, both mattresses are close to the neutral scale. I would rate both the Casper and the Leesa at a 6 out of 10 on the firmness scale (where 10 is the most firm). Additionally, both mattresses have great overall support.

Despite the similarity in firmness each mattress have its own unique feel.

Sinkage, Feel, & Motion Transfer

Laying Down Position

Both the Casper and the Leesa have similar sinkage in the laying down position. During my tests and measurements I found about 1-1.5 inches of sinkage. Despite the fact that the sinkage is the same, the feel is a little bit different.

With the Casper I feel a more pronounced “hug” of the foams around my entire body. This gives it a more enveloped feel when lying down. Casper’s website sums it up like this:

“The Casper provides supportive, cooling, and a cloud-like-feel. It is designed for your weight to be evenly distributed when sleeping, so the edges may be less supportive than a traditional spring mattress.”

The Leesa has a soft neutral feel also, but there’s less of a “hug” around your body and a little bit more of a push back. That said, I would not describe the Leesa as a firm mattress in any capacity. It’s still in the neutral scale, but you don’t get as much of a foam hug as with the Casper. Leesa’s website sums it up as follows:

“Leesa mattresses are designed to be great for all body shapes and all types of sleepers. Three layers of high quality foam deliver cooling bounce, contouring pressure relief and core support for amazing sleep…”

Sitting on the Edge

Edge support for foam mattresses is always a difficult task to accomplish. In general, both mattresses do a pretty good job in this regard. In a normal sitting position both the Casper and the Leesa have about 2 inches of sinkage. Sitting on the absolute edge the Casper collapsed a bit more at 5″ of sinkage, whereas the Leesa held it’s shape slightly better, only sinking by 4″. I weigh 140 pounds to give you an idea of the pressure on the mattress.

If you watch a lot of TV, get dressed in the morning, or otherwise use the edge of the mattress quite a bit, this is something to keep in mind. Overall, the Leesa is about average in terms of other foam mattresses and Casper is slightly less than average.

My wife, who has a tendency to sleep closer to the edge of the mattress, noted that she felt like the Casper created more a feeling of “falling off,” especially when she was getting up from the mattress. The Leesa’s firmer edges don’t have quite the same sensation, especially in a normal lying position.

Standing in the Middle

While it is something you would never need to do, I always stand in the middle of the mattress to test the mattress under the most pressure. Standing in the center of both the Casper and the Leesa, I saw 5 inches of sinkage for each of them (reminder: I’m 140 pounds).

Motion Transfer

As with most foam mattresses, motion transfer is extremely minor. My wife and I slept on the Casper and Leesa for several months, at no time during the night have I ever felt her move around, and generally I don’t even feel her get out of bed in the middle of the night.


Both mattresses are about the same in terms of price.

Should you buy the Casper or Leesa mattress?

This was a tough question and definitely one of the closest to call reviews I have ever done. After months of sleeping on both of these mattresses I believe the Leesa to be the better mattress.

Why is Leesa the better mattress?

  • Better & More Foam – the Leesa uses 4″ of specialty foam compared to only 3″ in the Casper. This means better durability and better deep compression support. Additionally, Leesa uses Avena foam as opposed to Casper’s latex foam. Avena feels very similar to latex, but has better durability.
  • The “It” Factor – I don’t always know what “it” is, but Leesa definitely has it. It’s hard to describe the balanced feeling of softness and support you get with the Leesa. I personally love the Leesa mattress. Among all of the mattresses I have tested (about 20 at this point) the Leesa is among a short list of the mattresses my wife and I keep going back to.
  • Thicker Cover – Personally, I like the Leesa’s cover design. But placing aesthetics aside, I have found the cover to just be better made. Leesa’s cover is thick, woven from a single piece of fabric, and very high quality. I like the softness of Casper’s cover, but found the extra soft fabric + porous nature to be problematic. When I was moving my Casper last time the fabric got caught and ripped threads out. I had a similar near miss with the Leesa, but the thick and smoother cover prevented the catching and ripping.
  • Firmness – the firmness with the Leesa is a very consistent 6 out of 10 (where 10 is the most firm). I’ve had numerous readers attest to this. However, the Casper seems to have a fluctuating firmness range. My wife and I tend to think it’s a 6 out of 10 on the firmness scale. However, I’ve had heavier sleepers reach out to me (180+ lbs) and say they think it is more like a 7 out of 10. I believe this is due to the softness of Casper’s top layer combined with their total 3″ layer of specialty foam. This could be resulting in deeper compression and engaging more with Casper’s memory and support foam.
  • Edge Support – edge support is always difficult for foam mattresses. Neither the Leesa nor the Casper were necessarily amazing in this area. However, the Leesa holds up a little bit better and does not completely collapse. Additionally, the Leesa does a great job in a normal lying position when close to the edge.

There are numerous other factors that were basically the same, including: support, motion transfer, warranty, trial period, pricing, shipping, and returns.

All that said, all things considered I prefer the Leesa mattress.
