Construction (Materials & Quality)

Casper Wave is a foam mattress designed for use on an adjustable or flat base (such as a platform bed or slatted frame), which the company also sells. Taller than their original product, it is 13 inches in height.

It comes conveniently delivered to your door, compressed in a box.

The comfortable, thick humidity-fighting wool cover that surrounds it feels and looks like a soft sweatshirt that helps keep you sleeping cool. It zips off for easy cleaning and resists tearing and wear when pulled.

Beneath the cover, there are five layers that are designed with strategic precision cutouts that comfort the body and promote proper ergonomic alignment.Casper Wave construction and layers

  • The first layer is made from 1-inch of Casper’s hypersensitive and virtually weightless “Flo foam.” The open cell structure helps to keep the sleeper cool throughout the night. In addition, this adds to pressure relief.
  • The second layer is a 1.5-inch latex level. Slightly firmer than the top layer, it also helps relieve pressure points.
  • The third layer is 1.5 inches of memory foam, which has been strategically placed deeper into the mattress. Unlike traditional memory mattresses that sink sleepers deep within, moving this layer beneath the latex enables people to move around comfortably on top while remaining in a deeper cradle. This strategy also helps to keep the sleeper cool.
  • The fourth layer is a 1.5-inch transition layer. Firmer than above levels and softer than the base, it provides a smooth handoff from soft pressure relief to support.

Notches have been cut out of the bottom of this layer in the hip region as indentations for the Supportive Gels in the base layer to be inserted. This flexible support feature keeps hips and spine comfortably aligned without dipping too deep.

  • The base layer is 7.5” of poly foam that serves as the support level. It has unique precision-cut channels that are designed to contour to your body shape and help with alignment and pressure relief. Gels embedded into the top of this foam administer further hip support. This feature works to ensure the comfort of nearly every type of sleeper.

It should be noted that this type of construction is not common in foam beds, making the Wave stand out from the competition. In addition, the configuration of materials helps to fight against the middle getting too soft and losing support over time.

Firmness (Support & Feel)

A medium-level firmness (see firmness guide) is comfortable for most individuals because it tends to provide enough support and pressure relief, no matter the sleeping position.

Due to the construction mentioned above, there are two distinct firmness levels. On a 10-point scale with 10 being the firmest, the hip region is a 5.5 and the rest of the Wave is a 4.5 to 5 level of firmness.

The Wave is softer than the brand’s original product. While you can plan on melting into the bed slightly, it is still easy to move around.

To the touch, you will notice the soft hypersensitive top layer seem to fade away. Pushing deeper into it, you will feel the increasing layers of firmness down to the base layer. Although there is a memory foam layer, the Wave is not slow-responding.

Back sleepers can reap the benefits of a balanced level of lumbar support and hips sinking into the mattress just so.

Stomach sleepers benefit from the elastic polymer inserts. While this type of sleeper can sink down uncomfortably in other foam brands, the inserts help to reinforce support and prevent the spine from falling out of alignment.

Side sleepers will notice the precision cuts in the upper region of the mattress and the elastic polymer provide the pressure relief they need. This is a key feature for side sleepers shopping around. At the same time, their concentrated weight should not sink too far down.

While significantly heavier individuals may sink deeper into the mattress than is comfortable, we believe this bed would be a good fit for nearly every sleeper.

Motion Transfer

Unlike innerspring mattresses that have a lot of bounce, foam brands excel at minimal motion transfer. They are able to isolate movements instead of shifting the area around where the Casper Wave is touched, and it gets high marks when it comes to reducing motion transfer.

If you have a partner, you will not be disturbed if they shift or get up in the middle of the night. This is especially good news for the light sleepers among us.

Edge Support

Historically, foam mattresses do not have as much edge support as innersprings. There are two types of edge support qualities to look for when purchasing, which is the feel of sitting on the edge and while lying down.

When sitting on the edge, you will sink slightly. While this is to be expected, it is rarely a problem since most of your time will be spent lying down. Likewise, you will notice compression when lying on the edge.

Value for Money

The Casper Wave’s unique construction and enhanced ergonomic support is a mattress we believe would be a great fit for most sleepers. While comfort is subjective for every person, the company’s attention to the needs of every sleep position is evident.

Although this luxurious bed is higher in price when compared to their original product, it is significantly less expensive than similar mattresses found in traditional stores.

With attention to areas such as shoulders, back, and hips through the zoning of materials, we think this mattress is one you should consider if you want a quality night’s sleep and consistency over time.
