Casper Wave Preview

The Casper Wave has some features you will not find anywhere else.  It’s ergonomically designed to cradle your back and provide good pressure relief.  We love the feel of it but the one complaint we would have is that it is not in everyone’s price range.

Casper Bed Review

As stated on the manufacturer website, Casper mattresses have shipped over a million units, and are a well respected name in the mattress market-place.

Their new Casper Wave mattress is hyped as an upgrade on the immensely popular original Casper model. This new version of the memory foam mattress boasts an added layer of foam, but that’s not the only change from the well-performing original. The main selling point of the Wave has to be the new Natural Geometry System, which provides extra support to extreme pressure points, while lightening the load on others.

Specifically, the base layer of the mattress is lined with grooves at the top and bottom ends, while the middle is strengthened to take the main bulk of your body weight. This ‘up and down’ pattern of the design is presumably where the Wave gets its name, although it could very easily apply to the sensation of weightless sleep that it works to provide.

Although not technically a hybrid, the Wave does mimic hybrid technology with its application of zone-specific support – a feature usually only delivered by a coil system.

The Wave enters the market in the premium price range, and has big competition in the face of its previous, much celebrated model. So does the Casper Wave live up to its expectation?

We’ve put together this in-depth review which examines every aspect of the mattress, to give you the knowledge you need to make the right choice.

What makes the Wave different?

Precisely engineered for ergonomic support where you need it most. It’s a breakthrough in sleep technology.
The​ ​​Casper​ ​Wave​​ ​is​ ​the​ ​summit​ ​of​ ​Casper’s​ ​unparalleled​ ​R&D​ ​—​ ​the​ ​result​ ​of​ ​intensive​ ​design​ ​and engineering​ ​work​ ​in​ ​Casper’s​ ​new​ ​lab​ ​in​ ​San​ ​Francisco.
The​ ​first​ ​mattress​ ​designed​ ​​to​ ​respond​ ​to​ ​body​ ​geometry,​ ​the​ ​Casper​ ​Wave​ ​uses​ ​​patent-pending,​ ​finely tuned​ ​contouring​ ​zones​ ​and​ ​polymer​ ​support​ ​channels​ ​that​ ​form​​ ​to​ ​your​ ​natural​ ​shape.
Designed​ ​as​ ​an​ ​ergonomic​ ​sleep​ ​surface,​ ​the​ ​Casper​ ​Wave​ ​provides​ ​superior​ ​spinal​ ​alignment​ ​while reducing​ ​pressure​ ​in​ ​the​ ​shoulders.​ ​The​ ​new​ ​top​ ​layer​ ​is​ ​a​ ​virtually​ ​weightless,​ ​velvety​ ​foam​ ​that​ ​melts away​ ​for​ ​effortless​ ​comfort.​ ​Together,​ ​this​ ​unique​ ​combination​ ​creates​ ​deeper,​ ​more​ ​restorative​ ​sleep

You will like the Casper Wave Mattress if you:

  • Like to sleep cool – Foam mattresses can sleep warm.  However, the design of the Casper with latex on top and memory foam on bottom helps it disperse heat efficiently.  I did not experience excessive heat at all.

  • Sleep in multiple positions – This mattress is a good medium feel with good body conformance.  Sleeping on your side, back or stomach Casper will conform to your body very well.

  • Like the combo of bounce and body conformance – With the Flo Foam layer on top Casper maintains good bounce which makes it easier to adjust positions and not feel stuck.

  • Require extra lower back support – The hyper elastic strips the Casper Wave has integrated into the middle of the mattress really does provide additional support in the lumbar area.
  • Are a side sleeper – The Casper Wave also has channeled foam that provides extra give in the shoulder area.  So for side sleeping you do not have a lot of pressure pushing back up on your shoulder.

You might not like the Casper Mattress if you:

  • Have a tight budget – The Casper is one of the priciest mattresses we have reviewed so far.  It does perform like a luxury mattress however.
  • Want a innerspring mattress – It can take time to get used to a foam mattress, if you already know you don’t like all foam mattresses you should stick with a coiled mattress. The Casper is a comfortable mattress but it won’t probably transform you from a spring fan to a foam fan.

Delivery & Set up

Casper will deliver the Wave for FREE, and even offer next-day delivery for an additional fee. They’ll send you delivery tracking information via email to allow you to keep an eye on the progress of your order. Orders must be placed by 2pm to qualify for next-day delivery and will cost $15.

Also for free, the manufacturer will provide their White Glove delivery service. They will bring the mattress into your chosen room, unpack it, set it up and remove all the packaging. They will also remove your old mattress and box spring if you so desire. An added bonus is that Casper donate any recovered mattresses to charity, or have them recycled.

Be sure to move the mattress into your desired room before opening, as it will expand quickly and may become more difficult to manoeuvre. Be careful not to damage the fabric of the bed when you cut it from its wrappings.

Free delivery is a common feature of most premium mattresses these days, so the Wave succeeds on that point. An additional bonus is the free White Glove delivery service, for which many companies will charge substantial fees. The opportunity for next-day delivery at a modest cost of $15 means the Wave scores high here.

Comfort & Feel

One word that keeps coming up when describing the Wave is ‘liquidy’. It’s not a word you would necessarily find in a dictionary, but it seems to be apt in describing how it feels to lay down on the Wave. The top layer of the mattress cradles you, while the bottom layers respond by providing support. 

The Wave falls at around 5-6 on the firmness scale, with 1 being the softest and 10 being the firmest. It’s worth noting that because of the Natural Geometry System, the bed may actually score a 5 at the top and bottom, and a 6 in the middle. The middle of the bed is designed to take the most weight, at your hips, and so is slightly firmer.

The general consensus seems to be that the Wave falls near the medium-to-firm range, so may not be the first choice for those seeking a softer bed. However, the contouring memory-foam still provides enough ‘lush’ to make for a comfy night’s sleep for almost any sleeper. The mattress is definitely aimed at the huge market of mid-range sleepers, and is a viable option for side, back or front sleepers.

The Wave is a premium product that ships with a lot of expectations. As far as overall comfort goes, it gives a good account of itself.

Motion Transfer

Foam mattresses generally excel in providing maximum motion reduction, as they are designed to absorb pressure without warping the entire surface of the bed. The absence of coils may result in a lack of bounce, but it also results in a super-responsive, contouring surface which can easily isolate individual pockets of pressure.

The motion reduction on the Wave is such that you can easily get in and out of bed without disturbing a partner. If sitting on the bed doing paperwork, you could sit your coffee cup right next to you and not have to worry about it spilling.

Reviewers online have testified to dancing on the bed while a full wine-glass sits on it, and it not having spilled a drop. We didn’t try that for ourselves, however we can testify that the Wave does well to reduce motion disturbance.

Off Gassing

As with all mattresses, when you open the Casper Wave you may notice a faint ‘new mattress smell’. This is pretty common and would be there no matter what brand you choose. Just like a new couch, a new car, or a new book, your new mattress will likely emit a slight scent for the first day or so.

Natural and organic mattresses are known to have more pungent smells, even though people often associate them with less off-gassing. The Wave does not use natural materials, but uses CertiPUR-US certified foams. Any scent you pick up from the mattress upon opening is completely harmless and will dissipate eventually.

For maximum effect, stand your mattress up on its end, and allow it to ‘air out’ for 24-hours before you use it. We recommend applying a mattress protector after the airing out process. After you lay your bed sheets on top of that, any smell should be gone.

A ‘new bed smell’ is a normal part of buying any mattress. The Wave performs no worse than most mattresses.


The Wave utilizes open-cell technology in its memory foam, allowing for ventilation and circulation throughout the materials of the mattress.

Unlike many of its premium competitors, the Casper Wave does not employ any kind of cooling layer. So how does it stand up to the heat test?

Well, it performs fine, quite frankly. It’s true that memory foam mattresses often result in a certain ‘stuffiness’, caused by the tightly compacted nature of the foam layers. But the breathable nature of the Wave’s materials, as well as its lush but well-ventilated cover, means it does a decent job when it comes to regulating temperature.

Perception of heat will change from person to person, based on age, weight, health etc. For some, adding a mattress protector would be too much. Overall, the Wave manages to stay cool at the best of times.

Edge Support

Foam mattresses are known to suffer a lack of edge support compared to hybrid or pure-spring models. So how does the Wave fare at the edges?

All in all, there’s not much to complain about. Because of the conforming nature of the memory foam, there’s no chance of you rolling off in the middle of the night. Sitting right on the edge of the bed will cause heavy compression, but the memory foam expands back into place very quickly.

For a pure foam mattress, the Wave performs admirably. Yes, there will be sinkage at the sides, but only when you’re sitting right on the edge. If this is an important factor for you, then take note. Otherwise, the Wave doesn’t raise any significant edge problems.

Casper Mattress Construction


The Casper Wave is made up of 5 layers of foam coming in at a height of 11.5-inches in total. Each of the layers combines to provide a balance between comfort and support.

The top layer is 1-inch of Flo-Foam, which provides a super-soft comfort layer that you will sink into.

The next layer is 1.5-inches of latex foam, which gives the mattress some resistance and bounce. It’s strong enough to provide stability to the upper layer, while also being pliable enough to move where your body moves.

Next we have 1.5-inches of memory foam. This layer reacts to your body and moulds itself to your shape. This allows your extreme muscular pressure points, like the shoulders and hips, to shape to the mattress without feeling any discomfort.

Then it’s the 1.5-inch support layer of high resiliency foam. This layer acts primarily as the transition between the comfort layers above and the base layer underneath. It’s in these final two layers that alternating grooves are cut out to allow for the zoned support mentioned earlier.

Finally the base layer – 5.5-inches of contoured support foam. This acts as the base-box of the mattress, and offers a strong foundation upon which the bed rests. This is also where targeted grooves are cut into the material to allow for zoned support.

To top it off, the cover is of a thick, soft, polyester and rayon, and provides lushness as well as breathability.

The materials that make up the Wave are solid parts that one would expect on a premium mattress. The lack of cooling layer is perhaps made up for by the hybrid-mimicking zoned support achieved by the grooves.

Casper Mattress Cover

Casper uses a zip off cover that has good elasticity and can be washed.

The cover is soft and plush feeling and good for cooling as it is not too thick.

Casper Foundation

Casper will work on any solid surface.  Wood foundation/boxspring, slats, floor or will work great on an adjustable base.

His and Hers – Firmness and Feel:

My thoughts (Ross)

I really like the overall feel of the Wave.  The top layer of foam is very responsive yet soft.  Many times I find that some mattress “features” are gimmicky.  Speaking about the Wave I think their design actually works.  The lumbar support makes a big difference for support and ultimately for longevity.  The grooved foam for the shoulders have added give to provide better pressure relief for side sleeping.

Her thoughts (Kayla)

The Casper performed well for me.  I am also lighter at 125lbs.  The top poly layer supports your lower back very well and bounces back quickly if you adjust positions.  I’m always worried about motion transfer since Ross moves around a lot.  Like most foam beds the Casper has very little motion transfer.

Softness-Firmness level: 6
1 Very Soft
5 Medium
10 Very Firm

Adjustable Base Performance:

The Casper will work great on an adjustable base.  Being an all foam it will bend easy and lay back flat when you are done.

Overall Summary

To sum it up then, just how good a deal does the Wave represent?
Well, first off, we’re talking about a mattress at the more expensive end of the spectrum, even within the premium bed market. The queen-size model will set you back $1,850, with the king-size coming in at $2,250. By keeping an eye out for discounts you may be able to get the price down further.

Casper offers interest free financing to help break up the payments.

Given its price, the Wave is expected to do big things. Regardless of price, it’s a comfy mattress that provides a great sleep. But some will still question its value, particularly in comparison to the original Casper mattress.
The original didn’t have the Natural Geometry System working for it, and has one less layer of comfort foam than the Wave, so I’m sure the manufacturers would say the price was justified.

We recommend the Casper Wave to anyone who:
Wants a mattress for a variety of sleeping styles.
Would benefit from extra support around the middle of the bed.
Desires a modern, memory-foam mattress from a trusted company.
Wants excellent motion reduction and pressure isolation.
Wants to sink in to the ‘liquidy’ surface.
Has the money to afford a luxury, premium-priced mattress.

Overall, the Casper Wave performs very well, regardless of price. Its predecessor set high-expectations, and only time will tell if the Wave manages to live up to those standards. But for now, we can say that this is an extremely comfy mattress that would be well worth treating yourself to.
