Casper is one of the best known brands in the bed in a box market and they’ve just released the Casper Wave as a new model to their line of foam mattresses. The new mattress aims to have a more luxurious feel to it and has an increased price to match.

Does the new design warrant the higher cost and build on the wildly popular original Casper mattress? Read on to see my thoughts on the Casper Wave!

Construction

The Casper Wave is made up of five foam layers, plus a thick cover, totalling 11.5 inches. The mattress has some unique elements to help make sure you are comfortable in any sleeping position including a zonal structure to lend support where it is needed most. With this construction it looks like Casper designed the Wave with a plusher feel in mind, but added extra support so the mattress still feels sturdy.

Cover – The cover is a pretty thick blend of polyester and rayon, giving the mattress a cozy feel to it. Despite the thickness of the cover, I found it to be breathable, and it didn’t cause me to feel as if I was overheating.

Casper says the cover was designed to express the experience of sleep and the shading goes from light up top steadily darkening to the bottom just as the layers of the mattress grow firmer as you approach the base. There is also the added bonus that the cover can be removed and washed.

Top Layer – The top layer consists of 1” of Casper’s proprietary Flo foam. I found this material to be extremely soft to help with pressure relief. It’s designed to draw body heat away from the sleeper and was actually cool to the touch, so it should help keep you from overheating.

Second Layer – The next layer down is 1.5” of latex foam to provide pressure relief with a bit of bounce. Often people will feel stuck in a plush mattress and find it difficult to change positions due to the slow response of the materials, such as memory foam, used in the comfort layer . Using latex foam should allow sleepers to move around better without sacrificing comfort as it has similar pressure relieving qualities to memory foam but more resilience meaning it won’t restrict movement in the same way.

Third Layer – After the latex layer is 1.5” of memory foam. Memory foam responds slowly to pressure and is known for providing pressure relief. The material also helps the mattress contour to your body. At times memory foam can trap too much body heat, but that shouldn’t be a problem with it this far down in the mattress. By placing this layer away from the surface of the mattress and below soft layers made of materials with more cooling tendencies the Wave takes advantage of the pressure relieving abilities of memory foam while guarding against the possibility of sleeping too hot.

Fourth Layer – Following the memory foam layer is 1.5” of high resiliency foam. This layer is meant to support the sleeper and act as a transition from the softer comfort layers above to the dense base layer below.

This layer also includes a polymer support network in the center of the mattress. The material has been added to help support your hips and keep the heaviest part of your body from sinking too far through the soft comfort layers above. This helps keep your back in a good position and avoid the formation of pressure points.

Base Layer – The 5.5” of high density poly foam base layer of the Wave includes contouring meant to improve spinal alignment. While the base layer is made of a pretty common material for foam mattresses and acts as the foundation for the structure, the contouring is designed to help with pressure relief so that you can feel comfortable in multiple positions.

The polymer support and the contouring of the base layer give the Wave a zoned design. This is is something that is different among most foam mattresses and something that is usually seen only in hybrid and innerspring mattresses. The goal here is to give support to the heavier parts of the body while providing pressure relief to common problem areas.

Firmness

People can feel the firmness of a mattress differently due to different sizes and weight distributions. Rather than just taking my word for it, I brought in three others to give their opinion on the firmness they felt while lying on the Casper Wave. This should give you a better sense of the range in firmness you can expect from the mattress.

Casper Wave Mattress Firmness Test

As you can see from the chart above, the testers were pretty much in agreement on the firmness of the Wave. Firmness in the range of 5.5 – 6 on this test means a medium firmness leaning toward a softer feel. The Wave has a plush feel but I wouldn’t say you get the feeling that it is engulfing you when you lie down.

The initial feeling when pressing into the Casper Wave is of the soft top layer of Flo foam, combined with the layers beneath, creating a luxurious feel to the mattress. While there is a slight feeling of sinking into the mattress, the Wave does a good job of keeping you from feeling stuck. I also felt that the mattress was doing a good job of relieving pressure, which we will take a closer look at in the next section of the review.

Pressure Map

Rather than just describe the feel of the Casper Waver, I wanted to give a visual representation of where someone may feel pressure while lying on the mattress. To do this I placed a pressure map on top of the Wave and lied on my back, side, and stomach. On the image below pressure will be represented from blue (low pressure) to red (high pressure).

When I initially lied down on the Casper Wave I could feel the mattress do a good job of filling in the space beneath my lower back, which is important for back sleepers. As you can see from the test results above, there aren’t any points of higher pressure while lying on my back. The Wave does a good job of distributing my weight, resulting in even support.

Once I roll onto my side, my weight gets concentrated over a smaller surface area. Strict side sleepers can often have issues in their shoulders and hips because of increased pressure in this position and Casper Wave had that in mind when they included the contouring in the base foam layer. The idea behind the inclusion of the contouring is that it would help keep your spine aligned in a better position. We can see on the image above that the pressure does rise slightly in the shoulder and hip areas, but in my opinion the mattress compares very well to other side-sleeping options in the market.

Finally, on my stomach, the results show pretty even pressure across my entire body. I didn’t find it difficult to breath in this position, which can be a problem for stomach sleepers. Another thing to keep in mind is that stomach sleepers need to be careful with softer mattresses as their hips can sink in and cause discomfort in the back. Casper took this into consideration and included the polymer support in the middle of the mattress and I found that while the Wave is a softer mattress, my hips stayed in a good position while I was on my stomach.

Motion Transfer

If you are sharing the mattress with a partner, you will want to know what it will feel like when the other person gets into and out of bed or tosses and turns during the night. This next test is helpful in showing the intensity of motion that is detectable from one side of the mattress to the other.

For this test I dropped a 10 lb steel ball from heights of 4 inches, 8 inches, and 12 inches and measured the disturbance on the other side of the mattress. This should be pretty intuitive: the bigger the lines, the bigger the disturbance.

I wasn’t sure what to expect from the construction of the Casper Wave mattress, but it performed quite well. The first drop, from 4 inches, shows very little motion transfer. This drop is used to simulate someone tossing and turning at night and in this situation the Wave should perform pretty well.

The 8 and 12 inch drops show larger levels of disturbance as the drop begins to affect lower layers of the mattress. These drops are meant to simulate someone getting into or out of bed, and here we see higher spikes in motion transfer, but still comparing well to other mattresses on the market.

Sinkage Test

When it comes to lying in bed, there are varying preferences on whether people would like to feel as though they are on top of or sinking into the mattress. To give a better idea of how different body parts might sink into the Casper Wave I used four balls of varying sizes and densities (a 6 lb medicine ball, an 8 lb medicine ball, a 10 lb steel ball, and a 50 lb medicine ball) and placed them on the mattress to measure how much they compress the surface.

These different sizes, weights, and densities help to imitate different body parts or different sized people to show how far into a mattress you may sink.

  • 6 lb medicine ball: A little more than 1 inch of sinkage.
  • 8 lb medicine ball: 2 inches of sinkage.
  • 10 lb steel ball: 2.5 inches of sinkage.
  • 50 pound medicine ball: 4 inches of sinkage.

Edge Support

If you’re going to be sharing your bed and need to use the entire surface area of the mattress, edge support is going to be an important attribute. Foam mattresses can struggle at times to live up to the edge support of traditional innerspring mattresses, so I wanted to see how stable and supported I felt while lying near the side of the Casper Wave.

The Wave performed well on this test as I felt even support going from the center of the mattress to the side. I was able to change positions and roll a bit with confidence that I wouldn’t fall out of bed. I was also able to hang off the mattress a bit while lying on my side and didn’t see too much compression.

When I sat on the edge with my weight over one point (think putting your shoes on in the morning or getting into bed at night), I saw a bit of compression. This is pretty common among foam mattresses and this position may not be all that important when making your mattress decision, but I just wanted to give you an idea of what you can expect.

Is the Casper Wave the right mattress for you?

Now that I’ve had a chance to take a look at what makes up the Casper Wave and been able to get a feel for it, it’s time to talk about who this would be a good fit for:

  • Someone sleeping in all sleeping positions – The construction of the Wave creates a good sleeping experience for a wide range of sleeping preferences. The mattress mixes soft layers with responsive materials to give the pressure relief of a plush mattress with strong support in certain zones for back and stomach sleepers.
  • Someone looking for great spinal alignment when side sleeping – the contouring in the base layer as well as the polymer support are designed to help keep your spine aligned and relieve pressure in your shoulders and hips.
  • Someone who likes a soft yet supportive feel – If you are looking for a soft mattress, but still want to feel secure in bed the Wave does a good job of combining a plush feel with solid support. It’s tough to explain but the mattress has the pressure relief of a softer mattress while still feeling sturdy.
  • Someone looking for a luxury feel (and willing to pay a more luxury price) – Again, this is tough to explain, but if you have ever stayed in a high end hotel and had success sleeping on that kind of mattress, then the Wave could be right for you. The Casper Wave is a great value (in my opinion), since it is a very well constructed mattress, but it is priced above many bed-in-a-box competitors, including the original Casper mattress.
  • Someone looking for contour and mobility – Both the top layer of Flo foam and the layer of latex beneath are soft yet respond quickly to pressure. This means they provide pressure relief but still allow for the sleeper to adjust positions. By placing these layers above the memory foam, you get the contouring benefits of all three without having to worry about feeling stuck.
