The Casper Wave is the newest offering from a major player in the online mattress-in-a-box scene. The Wave was built to serve as a more luxe version of the original Casper. Thanks to more expensive memory foams and fabrics, it certainly costs a significant chunk more.

Casper spent three years sorting through customer feedback and then developing what became the Casper Wave. It wanted to upgrade the base model in a significant way. Recently Casper’s co-founder told Consumer Reports that the price increase was due to the cost tied into bringing in“relatively firm” latex foam layer from where it is manufactured in Belgium.

They were trying to hit a home run with some different layers of material and design to make the CasperWave more ergonomic. (An ergonomic design means designed for efficiency and comfort.) In this case, the Casper Wave is cut and constructed to fit each part of your body.

Tall order, right? Building a mattress that can adapt to different body parts is difficult because your pressure points require different levels of support. Your head and neck, your shoulders, your hips, your back, your booty—all of these parts are shaped differently and weigh different amounts and, thus, need different levels of pressure relief.

Casper, in business since 2014, believes it has delivered its most innovative design, one that supports and curves where it needs to while also including cooling features to keep you snoozing easily through the night.


Look for these features with the Casper Wave mattress:

  • Different foams and materials in different densities support your body at 33 different points along the mattress
  • Several layers of foam are actually curved in the middle layers to mold to your pressure points, i.e., shoulders, hips, back, etc.
  • Added layer of latex foam for better contouring and support
  • Built for side sleepers, heavier sleepers and anyone who suffers from back or joint pain 
  • Endorsed by the American Chiropractic Association
  • Can also find mattresses at some Target & Nordstrom stores
  • 100-night free trial
  • 10-year limited warranty
  • Free shipping and free returns in the contiguous U.S. and Canada
  • CertiPUR-USⓇ certified air-flow, memory & support foams free from harmful chemicals
  • Also wool cover and latex foam are OEKO-TEX® certified



The Casper Wave is a 11.5-inch memory foam mattress.


Heat retention has been an issue for memory foam mattress makers since time began. We’re not kidding. Time meaning dating back to 1991 when the first memory foam mattress debuted.

The Casper Wave is built, however, with several layers of memory foam that are perforated to allow airflow, a key to cooling you down as you sleep. The mattress cover is also made of wool, which was designed to limit humidity. They also cut channels into the dense base layer. While that was for more contouring, it also is space for air to flow through. That’s three features to encourage airflow and work together to keep you cooler. See: Best Cooling Mattresses 

Casper Wave Mattress Firmness

The Casper Wave is a firmer mattress.

Obviously, this is a memory foam mattress so lighter people will experience the foam layers differently than heavier people. Some will sink in more than others just because of a difference in weight.

Though it’s a firm mattress, the Casper Wave also has been cut and ordered through the three middle layers in a way that will contour to your body. The layers are already curved to your hips, thighs, and shoulders so it may not feel as firm as it is.

Edge support

Partners who need to use the full surface of the mattress should do just fine on the Casper Wave. The edges supported sleepers well in any position and held up well while someone sat on the edge while getting ready for the day. The edge support of this mattress makes it one of the best mattresses for couples

Motion transfer

You do not want to wake up when your sleep partner—a spouse, a significant other, a child, a pet—gets out of bed to use the potty or, in the pet’s case, to roam the house. (We don’t know your pet’s life. Maybe they don’t wander, but you get the idea.)

The Casper Wave does a good job keeping motion on the side where it begins. Remember limiting motion transfer is important if you sleep with someone who has a different sized-bladder or a different wake-up/bedtime than you. You don’t want all of that jostling to wake you up unnecessarily.


The 11.5-inch Casper Wave is made of 5 layers designed to support and contour to your body in the places and ways you need most. It’s constructed with open-cell foams to help keep you cool and a newly designed wool-blend top layer with a soft, velvety feel.

The wool itself naturally wicks moisture away so it fights humidity to keep you cool starting from the very top of the mattress.

The first foam layer is 1 inch of comfort “flo” foam that sort of acts like a pillow top because it is so soft. You sink in before you interact with the other layers below. It’s an easier transition to the layers below because it feels plush.

The second layer is 1.5 inches of breathable latex foam. Remember that latex materials have more bounce to it than traditional memory foam. It responds quickly to pressure, but it allows you to get in and out of the bed without sinking too far and getting stuck.

The third layer is 1.5 inches of a pressure-relieving memory foam that does a lot of work to contour to the curves of your body and cut pressure at your neck, shoulders, hips, and thighs. While memory foam is usually used for contouring, again, you won’t feel trapped since this layer is below the bouncy latex foam layer.

The fourth layer is 1.5 inches of polyfoam that is stamped on the bottom with “supportive” and firm gels at the middle of the mattress where your hips sit. Its extra support in that region so stomach and side sleepers don’t feel their hips sinking too far into the mattress and throwing their spines out of whack.

The fifth layer is thick, a 5.5-inch, high-density poly foam slab that stabilizes the mattress. There are channels cut into this layer, more to accommodate the width of your shoulders and other curves if you sleep on your side. There are other supportive gels cut into the top of this layer, again for hip support. The channels should also encourage airflow, again to help rid the mattress of unwanted heat.

The Casper Wave comes with a 100-night risk-free trial. Casper has given customers a friendly policy whether the mattress is being delivered or returned.

The Casper Wave comes with free white glove service. Someone will unpack it for you and discard of the packing supplies at no extra charge.

You do have 100 days to decide whether to keep it. If you return it, they’ll send a courier to pack up and take away the mattress at your convenience if you end up returning it. They’ll try to donate it to a local charity or recycle it and you will get a full refund if you do send it back.

Casper Wave Mattress Warranty

The Casper Wave mattress comes with a 10-year limited warranty for the person who originally bought the mattress only. It covers defects in materials and workmanship when used as intended, including using the right foundation to support the combined weight of the sleeper and the mattress.

It covers sags greater than 1 inch that did not result from improper use or a weak foundation. It covers physical flaws that force the foam to crack, but not if you used the mattress improperly. It covers any problems with the zipper that came as a result of bad workmanship.

The Casper Wave warranty requires you to use their mattresses on a solid platform, a solid box spring, a bunkie board on a box spring, the floor or an adjustable base.

Nerd Score: 4.8/5

Casper is ambitiously trying to capture higher-end clientele with the Casper Wave, the luxe version of its original mattress. It costs quite a pretty penny more, in the neighborhood of $600 to $1500 more depending on the size you buy.

Casper constructed the wave to contour to different body parts (neck, shoulders, hips, thighs, back) which need different levels of firmness and contour to keep your spine aligned through the night. That is critical if, before, you were waking up feeling sore in any of those pressure points.

They have curved some of the foam, cut channels into the base layer, and used supportive gel to give the variety most side and back sleepers need.

The Wave is an expensive purchase. Still, if you’re a combination sleeper who likes a firmer mattress, and the contouring and support work for you to ensure 7-8 hours of sleep per night, the money will be well-spent.

(NOTE: A tip for people who do end up loving the Casper Wave: Because the mattress is contoured in the middle layers, it has to be placed a certain direction on your foundation. You should always orient it with the cover zipper at the bottom and the lighter side of the mattress facing up.)
