Brand Snapshot

Since its launch in 2014, Casper has grown into one of the most well-known bedding brands on the market, period. It sells three different mattresses, three different pillows, bed frames, bedding, sleep accessories, and more, marking it as a one-stop shop for all things related to cozy slumber.

While I won’t be getting into all of these products today, I will take some time later on to compare the Original Casper to its mattress siblings, the Casper Nova Hybrid and Casper Wave Hybrid. I’ll also size up the Casper against two of its biggest competitors in the space: the Purple and Nectar mattresses.

But before we get ahead of ourselves, let’s turn our attention back to the Original Casper.

What is the Casper Mattress Made Of?

The Casper mattress is built with three layers of foam, including a top layer of breathable aerated foam, a middle section of zoned support, and a sturdy bottom layer of high-density poly foam (or pocketed coils, for the Hybrid version).

This combination of materials is intended to produce a balanced, medium firm feel. To see if the brand pulls this off, let’s take a peek under the cover!

Cover – Made of a knit polyester blend, the Casper cover has a soft and stretchy feel to it.

Comfort – Things truly kick off with this top layer of aerated foam. The material has a slow response to pressure, which allows the sleeper to sink in slightly for pressure relief at the shoulders and hips. Though this kind of contouring would usually produce some overheating, the small aerations along the material’s surface help to promote some cooling breathability throughout the structure.

Transition – Up next, you’ll land on a memory foam layer of zoned support. Basically, what this means is that the section has been divided into three different zones, all of which feature slightly different firmnesses. There’s softer foam at the shoulders for a bit of pressure relief and firmer foam at the hips for a little lift. This creates a nice, balanced vibe that works to position the spine in a healthy, neutral alignment.

Base – In the all-foam version of this bed, the base is made of a thick layer of high-density poly foam, which provides shape and stability to the structure. In the hybrid version of this bed, the base is made of a pocketed coil system, which brings a little extra bounce to the party. If you’re a combo sleeper or someone who simply enjoys some buoyant lift, the hybrid could be a great fit for you!

How Does the Casper Mattress Feel?

Now that we’ve got a solid sense of what’s going on inside the Casper mattress, let’s talk about how it feels, starting with firmness.

Like any feel factor, firmness is quite subjective, and can change a lot depending on one’s body size, shape, and weight. Therefore, my read of this bed’s firmness could very well differ from your own. For reference, I’m about 5’10”, 190 lbs. and prefer to sleep on my stomach.

The Casper has a medium firm support level

After rolling around on the bed, I decided to give the Casper a 7/10 on the firmness scale. When compared to the industry standard of 6.5 for medium firmness, it’s clear that this bed is slightly firm.

The mattress got a 7 from me because I think it’s got a firmly supportive feel. Though the foam materials are soft to the touch and provide some nice relief at the shoulders and hips, the overall design works to lift the sleeper up and out of the structure. This creates more of an “on top” of the bed feel, which could work great for back and combo sleepers. I should mention that the 7/10 firmness rating holds true for both the all-foam and hybrid Casper mattress.

Testing the Casper Mattress

While firmness can tell us a lot about how a bed feels, it’s far from the only thing to consider when shopping for a new mattress. So, that’s why I’m going to test this bad boy for two more factors: Pressure Relief and Motion Transfer.

Pressure Relief

Pressure relief refers to a bed’s ability to alleviate tension at the shoulders, hips, and lower back. This is an important measure for all sleepers, but especially those who struggle with pain at night. To demonstrate the Casper’s pressure relief, I’ll be testing it out with a pressure map.

Basically, it works like this: I roll out the device, hop aboard, and let the map do the rest. As I roll around, the map records how much force I’m exerting on the mattress, creating a colored “map” of the pressure. For reference, blue indicates areas of low pressure and red indicates areas of high pressure.

Back – The Casper felt fantastic on my back! As I sank through the top layer of aerated foam, I could feel the materials lifting up my hips and filling in the space at my lumbar region. The transitional layer of zoned support worked particularly well at setting my spine in a nice, even alignment.

Side – As I turned onto my side, I continued to feel some nice comfort. However, the longer I stayed in this position, the more uncomfortable it got. In my opinion, this bed is just a touch too firm for strict side sleepers, many of whom prefer plush structures for deep body-contouring and pressure relief. That being said, combo sleepers who switch between their back and side in the night should be totally fine.

Stomach – And finally, I rolled onto my stomach. In this position, I felt okay: not bad, not great. The mattress is firm enough to support occasional stomach sleeping, but I think strict stomach sleepers will probably prefer a much firmer bed that lifts the hips in completely neutral alignment with the shoulders.

Motion Transfer

Let’s wrap up this section with a look at motion transfer, which refers to the amount of movement detectable from one side of the bed to the other. All sleepers will want to pay attention to this feel factor, though it will probably be most relevant for those who share their bed with a partner.

To illustrate this motion transfer, I dropped a 10 lb. steel ball from heights of 4 inches, Eight inches and 12 inches and measured the disturbance it caused: the bigger the lines, the bigger the disturbance.

These motion transfer results tell me that the Casper does a pretty decent job of isolating motion across the structure. While you’re still likely to feel your bed mate moving around, it shouldn’t be so major as to seriously disrupt your slumber.

Casper Vs.

After giving the Casper a thorough once-over, I thought it might be beneficial to size it up against some of its biggest competitors on the mattress market, namely the Purple and Nectar mattresses.


  • Though the Purple is also a popular bed-in-a-box mattress, it’s got a very different feel from the Casper, thanks to its hyper-elastic polymer smart comfort grid.
  • This grid is composed of a bouncy and cooling material, so could be great for combo sleepers who tend to overheat at night.
  • The collapsible grid is also fantastic at alleviating tension across the body, especially the hips, shoulders, and lower back.
  • I should also mention that the Purple mattress is comparably priced to the Casper.
  • Read my full Purple mattress review.


  • Like the Casper, the Nectar is also an all-foam bed, though it’s built almost entirely of memory foam. This gives the mattress a super plush feel with plenty of sinkage, body-contouring, and pressure relief.
  • In general, I tend to recommend the Nectar for strict side sleepers who are most likely to enjoy the bed’s thick top layers of memory foam.
  • One slight drawback to the Nectar is that all that memory foam leads to overheating, which could pose a problem for some sleepers.
  • Pricewise, the Nectar is a much more affordable option than either the Casper or the Purple, so could be a good pick for budget shoppers.

Getting a close up look at the Casper Original

The Casper mattress doesn’t just face competition from other brands — it also faces some pretty stiff competition from other beds in the Casper line. So, let’s briefly go over both the Casper Wave Hybrid and the Casper Nova Hybrid.

Casper Wave Hybrid

  • Billed as Casper’s luxury model, the Wave is made up of five layers of foam and springs to create a structure that’s as pressure-relieving as it is supportive.
  • One way it does this is by utilizing the brand’s Zoned Support™ Max system, which features gel pods under the waist and lower back for extra support.
  • Therefore, this bed is perhaps most well-suited for folks who struggle with aches and pains at the shoulders and hips.
  • Pricewise, it’s the most expensive Casper mattress, so may not work for those on a tight budget.

Casper Nova Hybrid

  • The Casper Nova Hybrid is a dynamic mattress that’s both super plush and incredibly supportive.
  • Like other Casper mattresses, the Nova comes equipped with a special layer of zoned support, which works to lift the hips and cradle the shoulders for optimized spine alignment.
  • Compared to the Original Casper, the Casper Nova is much, much softer. In fact, I rated it a 5.5/10, which means it could be especially good for side sleepers or those who prefer a cuddly sink.
  • Pricewise, it’s right in the middle between the Casper and Casper Wave mattresses.

Should You Buy the Casper?

The Casper Original is a medium firm all-foam mattress that does a pretty good job of sleeping cool through the night. The zoned support system is a nice touch for those suffering from back pain and the support level is great for back sleepers.

Casper Pros

  • First and foremost, I think this mattress could be a great fit for back sleepers. Not only is it easy to move around and change positions, but the bed does a great job of positioning the spine in a nice, even line.
  • The soft feel at the shoulders makes Casper an awesome option for those trying to avoid shoulder pain!
  • In general, I think this mattress could be a good fit for folks who are struggling with back pain as it strikes a satisfying balance between pressure relief and support.

Casper Cons

  • The bed may not be quite right for heavy people in need of stronger support.
  • To that point, the Casper mattress doesn’t really feature too much body-contouring. If you’re someone who wants to feel as though they’re sinking “into” their mattress, this may not be the right bed for you.
