Casper spent a significant amount of time doing research and development on the Wave, and after three years, with the launch of Casper Labs, Casper applied millions of data points, renowned expertise in foam research, and years of sleep science to the goal of reinventing the mattress once again.

What emerged was another breakthrough in mattress design — the Casper Wave, the luxury mutli-layer, zoned comfort premium mattress that we tested and give our opinion on in this review.

If you like the feel of memory foam and have been looking for a premium mattress that sleeps cool and is very comfortable, the Wave may be the mattress for you!  Review updated Jan 5, 2022 @ 7:14 pm

This in-depth review of the Casper Wave mattress evaluates all of the criteria we use to determine what constitutes a good mattress, which includes firmness / support, comfort, sleeping hot, and other features as outlined below.

Construction and Materials

The Wave mattress is a 11.5″ memory and latex foam mattress made up of 5 layers

  • 1″ Top Comfort Layer – This layer is 1″ of weightless Flo Foam that provides cooling and comfort to the mattress, as well as provides good pressure relief. It is designed to draw body heat away from the sleeper and feels cool to the touch.
  • 1.5″ Response Layer – This layer is 1.5″ of latex foam which provides bounce and responsiveness to the mattress, and helps you move around on the bed during the night without feeling stuck in foam.
  • 1.5″ Transition Layer – This layer is 1.5″ of visco elastic memory foam, which provides a transition layer between the upper comfort layers and the lower support layers, and provides body contour and hug.
  • 1.5″ Zoned Support Layer – This layer is 1.5″ of high resiliency foam with a polymer network, which provides multiple zones of support to the body and provides support where it is needed most.
  • 5.5″ Foundation Layer – This layer is 5.5″ of contour cut foam that works with the layer above to provide the zoned support as well as acts as the foundation and provides deep compression support and contouring support for the body.

The cover of the Casper Wave mattress is a thick blend of polyester and rayon, which provides a soft and cozy feel to the mattress. The cover is thicker than many other mattresses, but remains breathable and helps keep the mattress cool.

Firmness & Support

The Wave mattress comes in a universal comfort firmness option, which is designed to meet the majority of sleepers.  The model we tested we rate it at a 6.5 out of 10 (10 being the firmest).

The Wave mattress feels initially somewhat firm, as the more responsive top comfort and support latex foam layer provides the body with response and contour without the “sinking in” sensation that memory foam is normally known for. However, after the initial break in period and our bodies adapted to the mattress, it felt less firm.

With many mattresses, since I am a heavier sleeper, I tend to press through the top comfort layers and feel more of the support layers which are often harder and not as comfortable.

This isn’t the case so much with the Wave, however, as the thicker 11.5″ mattress provides enough support in the comfort layers without making me compress through them and come to rest on base support layers.

The combination of latex and memory foam does a great job at providing body hug and contour without feeling “trapped in foam” like some all-foam mattresses feel like.  So you get the best of both worlds with the Wave – the hug and contour of memory foam, with the responsiveness and bounce of latex.

We felt the Wave mattress does a good job of providing support in all sleeping positions for both Kaye and myself sleeping as a couple.

In terms of support, the Casper mattress does a good job of providing excellent support in all sleeping positions. Since Kaye and myself are primarily side sleepers, we like mattresses that provide enough give in the top comfort layer to support our shoulders and hips, while also having the firmness if we switch to our stomachs and backs.

The company deploys a zoned “Hyper-Targeted Support” layer that ensures ergonomic spine alignment and ensures the correct support for different areas of the body based on which ones need more or less support. Something that is often found on mattresses costing 3-4x what the Wave costs.

Back sleepers and stomach sleepers will also find the Casper Wave good for those styles as well, as it is firm enough to provide support and comfort for those sleeping styles without being too soft and causing excessive sinkage.

As we are primarily side sleepers, we like mattresses that provide enough give in the top comfort layer to support our shoulders and hips, while also having the firmness if we switch to our stomach or back. The Wave mattress does a great job at this.


The Wave mattress is quite comfortable, by utilizing a variety of foam layers all together to provide a comfortable, all-foam mattress with enough body hug and contour for those that like the feel of memory foam, along with the bounce and responsiveness that latex foam brings as well.

The top comfort layers provide very soft and sensitive foams that have a soft, velvety feel and literally allow your body to “melt” away during the night once the support functions kick in. Something we have not felt with the majority of all-foam beds we have tested.

The layers of latex foam and memory foam provide the response needed to switch positions during the night and support my heavy bodyweight with ease, without causing too much movement during the night for Kaye when I get up or move around.

The Wave has that classic memory foam body contouring and hug feel without experiencing that “sinking down into a hole” feel that traditional memory foam mattresses often feel like, and the inclusion of latex foam provides the response that is needed for moving around during the night without feeling trapped in foam – and also providing the necessary bounce needed for sex!

The Casper Wave mattress is both very supportive as well as being a very comfortable mattress, and the premium materials all lend themselves to accomplishing this.

Sleeping Hot

The Wave does a good job of not sleeping hot  due to the open-cell, heat wicking foam layers which divert excess heat away from your body to keep it cool at night.

As a couple who has tested over 75 mattresses, this is a big deal for us and something that the Casper Wave does a great job at – preventing heat buildup or causing sweating during the night.

Living in Texas and sleeping together as a couple, we always make sure to evaluate all foam mattresses quite closely for heat retention – since that is something that is important when choosing a mattress.

As mentioned, the Wave does an excellent job at preventing heat buildup due to the materials used in the design of the mattress, which again – many all foam beds do a poor job at.

Sinkage & Motion Transfer

The Casper Wave mattress does a good job with minimizing sinkage compared to many competing all foam mattresses. As we always preach, sinkage (and motion transfer) is largely weight dependent.

The fact that I weigh around 230lbs tends to have a rather large bearing on the degree of sinkage I experience when sitting and lying on a mattress. Kaye, who is half my weight, experiences much less sinkage than I do, but again this is to be expected due to her much lighter weight.

We often have a big issue with thinner foam mattresses causing excessive sinkage when sleeping, and it is a big pet peeve of ours having tested quite a few beds over the last few years.

The 11.5″ thick construction is also a welcome change compared to most online “bed in a box” mattresses we have tested, which tend to average 10″ which is often too thin for our preference.

The multiple layers of latex and memory foam provide a good degree of bounce and responsiveness, without causing too much motion transfer or sinkage with the 11.5″ thick design really supporting heavier sleepers such as myself quite well.

Therefore, motion transfer was much less than many competing beds not only due to the inherent design and construction of the mattress, but also due to the research and work put into the Wave by Casper Labs – who spent a significant amount of time engineering the mattress to provide multiple zoned comfort along with making sure it prevented sinkage and motion transfer, which is important for couples.

As a couple testing over 75 of the leading mattresses, we often have a big issue with motion transfer when getting in or out of our bed during the night. This has caused quite a bit of conflict between myself and Kaye with some beds, which often shake and move when my heavier weight gets in or out of the bed.

Not so with the Casper Wave mattress, which does an excellent job at isolating motion transfer between two sleepers due to the aforementioned zoned design of the mattress.

Casper Wave profile

Edge support is quite good with this mattress, and better than most all foam mattresses we have reviewed. The high density foams used in the construction of the mattress do a good job at providing even support throughout the mattress, including the edge, which is something that we often find lacking with all foam mattresses that don’t have specific edge support features.

I made sure to sleep near the edge at times to test this and did not experience any of the “rolling off” the edges or having them become compressed under my weight. With some poorly designed mattresses, when sleeping on the edge due to my heavy weight i will compress the edges quite a bit and roll off the edge of the bed.

When sitting up, I did compress the bed to a reasonable amount, but this is to be expected given my 230lb weight – but again, was much less than many other foam mattresses, due to the thicker 11.5″ construction and multiple layers of high quality and dense foam.

Smell / Off-Gassing

The Casper mattress gets high marks in this category for not having too much of a noticeable smell upon opening the box. Although the Wave is pretty much an all-foam mattress, which normally when shipped in a box tend to have a degree of smell and/or off-gassing from the foam that is compressed and packed in a box.

The Wave has markedly less off-gassing and odor that foam mattresses usually have, which was rather surprising to us given the all foam construction.  Something that we tend to notice quite a bit, and thankfully with the Wave, we did not experience.

Casper set out to raise the bar with a new luxury premium mattress, and has done so with the Casper Wave mattress.  The Wave delivers a luxurious, comfortable yet supportive sleeping environment with premium materials and at a premium price. The memory foam and latex mattress delivers on providing an excellent bed at a price less than ones costing much more.

The Wave was designed to provide excellent support for all sleeping positions, by the use of their zoned mattress design that provides support where it is needed the most. The Wave provides this support quite well, and at the same time does so with a comfortable bed with a sumptuous feel as well.

This mattress does a good job at sleeping cool, and at 11.5″ thick, also does a good job at supporting heavier sleepers as well as couples. The mattress does a good job at minimizing sinkage and reducing motion transfer, as well as provides excellent edge support as well.

In addition, the Wave does a great job at not sleeping hot, which is something many all foam mattresses often fall prey to.

All in all, the Casper Wave is an excellent foam and latex mattress that is comfortable, cool, supportive, and luxurious at a price comparable to beds costing much more.  The Wave is a great choice for couples that like the hug and countouring feel of memory foam as well as the bounce and response of latex.

We hope this review of the Casper Wave mattress helps in your next purchase decision!
