While there are many advantages to the Casper mattress, no single mattress can satisfy the needs of every sleeper. Let’s go over the ins and outs of who would benefit most from this mattress, who would not, the materials used, and everything else you need to know before purchasing.

Casper Mattress Reviews - Should You Buy? (2023)

What to like about the Casper

Because of the open-cell structure of the foam, this bed stays surprisingly cool for a memory foam mattress.

The Casper is cheap, coming in at less than $1,500 for a king.

The bed’s zoned support system is particularly beneficial for side sleepers.

What to not like about the Casper

No one weighing more than 250 pounds should try to sleep here.

Those seeking a bed with the contouring qualities of memory foam will be disappointed by this option.

Who the Casper is Best for

Side sleepers

The Casper’s zoned support foam is great for side sleepers because it maintains spinal alignment while you sleep. The Casper has three layers and is a medium-firm mattress. Pressure points (hips and shoulders) are supported by the bed’s firmest sections, while the softer sections (feet and shoulders) provide comfort.

Hot sleepers

Pure memory foam mattresses have a reputation for absorbing heat throughout the night, which can make hot sleepers uncomfortable. The polyfoam used in the Casper’s top layer has been perforated to increase airflow and reduce the mattress’s temperature.

Who the Casper is not best for

Stomach sleepers

Sleeping on one’s stomach causes the hips to fall out of alignment, putting extra strain on the lower back and the neck. Our sleep experts found that the Casper, despite its zoned support foam’s ability to relieve pressure in these trouble spots, was too soft to be a good option for stomach sleepers. Our guinea pigs suggest looking into a hybrid model instead if you care about your hip alignment.

Larger-sized sleepers

The Casper mattress is great for most people, but it may not be supportive enough for those who are particularly tall or heavy. Memory foam does not provide enough structure, unlike hybrid or innerspring mattresses, to properly support their weight. Larger members of our testing team reported that the Casper mattress did not provide enough support for their hips or shoulders, a problem that would be solved by the inclusion of coils.

How the Casper Mattress Sleeps

When it comes to relieving pressure, responding to pressure, and isolating motion, the Casper mattress truly shines. The Casper lacks the contouring of many memory foam mattresses, so it won’t give you that snug feeling of being encased in your bed like some of its competitors. If you prefer a bed that is neither too soft nor too firm, this one might be a good fit.

Pressure relief

Overstressing pressure points like the hips, lower back, shoulders, and neck is a risk of sleeping on the wrong mattress. You can get more restful sleep on a mattress that doesn’t make your aches and pains worse and even helps alleviate pressure points. The Casper’s weight is distributed evenly thanks to its zoned foam support, so users can expect to wake up without any new aches and pains.

Compressed foam can prevent air circulation and trap body heat, so most memory foam mattresses have a reputation for being too warm to sleep on. Casper is cooler than most memory foam mattresses, but sleepers who run hot may want to consider a hybrid or innerspring mattress instead.

Motion isolation

Prioritizing motion isolation would be wise if either you or your partner are restless sleepers. You and your partner need a mattress that blocks motion to keep from disturbing each other’s sleep. Our sleep experts found that the Casper provided high levels of motion isolation, meaning that you could get up and move around in bed without waking your partner.


A mattress that responds quickly to your movements is called “responsive,” and it allows you to change positions without feeling like you’re fighting the bed. Beds with innersprings or hybrid technology are known for their responsiveness, preventing sleepers from feeling trapped. The Casper avoids the compromise between responsiveness and contouring properties common to memory foam mattresses. Our evaluation team gave this bed a perfect score because of how well it responded to their movements while sleeping.


A new mattress is an expensive purchase, so it’s important to find one that will last for years. The Casper is a sturdy mattress that can withstand the test of time because of its high-density foam foundation. Our durability tests gave it an 8 out of 10 overall.

Edge support

Have you ever rolled close to the side of the bed while sleeping? When you lie or sit on the edge of a mattress and it gives way under your weight, the mattress lacks edge support in its design. Because the Casper’s edges are just as supportive as the bed’s middle, you can make use of the entire sleeping surface (and even feel supported just sitting on the edge).

Key Features of the Casper Mattress

Materials and construction

Casper’s all-foam construction consists of a top layer of cooling memory foam, a middle layer of zoned support foam, and a bottom layer of support foam.

Top layer

The perforated polyfoam used in the Casper’s plush top layer is there to promote airflow and relieve pressure. This foam strikes a nice balance between softness and bounce, so you can relax without getting stuck.

Middle layer

The Casper’s zoned support layer is located in the mattress’s center, and it’s made to give more support where it’s needed (the hips and lower back) while also cushioning the sleeper’s shoulders and feet.

Base layer

Casper uses a high-density foam in its mattress bases, making for long-lasting comfort and support.

Returns and warranty

Casper has such faith in the quality of its mattresses that it provides a 10-year warranty covering any defects in construction. The mattress can be returned for a complete refund if any flaws are found. Best of all, Casper will arrange for pickup from your home. It’s important to remember that using an unsuitable bed frame will render your mattress warranty null and void. Casper provides some tips for picking the best one.

Trial period

Manufacturer warranties are great for safeguarding against faulty products, but what if you just don’t end up liking the mattress? Here’s where the “try before you buy” sleep policy comes in handy. The 100-night sleep trial that comes with every Casper mattress gives you plenty of time to try out the bed and see if it works for you. There are no hard feelings if you decide the bed isn’t for you. During the trial period, Casper will pay for the cost of shipping back to them.

Delivery and shipping

Since Casper is a “bed-in-a-box” company, transporting and delivering the product is a breeze. The mattress can be purchased from Casper or Amazon online, and once it is yours it will be compressed and rolled up into a box for easier transport. The Casper mattress is ready for use as soon as it is unboxed and allowed to expand to its full size, which takes only a few hours.

What Is The Casper Mattress Firmness?

Casper mattresses are medium-firm, falling in that sweet spot between very soft and very firm. Casper, on the other hand, has a number of different models, each of which can give the sleeper a slightly different experience. Let’s take a closer look at the firmness of the Casper Original and some of their other mattress options.

Is Casper Original firm?

The Casper Original has a firmness level of 5, making it a medium feel mattress. The Casper Original Hybrid has a coil support layer instead of polyfoam, but both versions use three foam layers. The Casper Original Hybrid has a similar medium feel, but the coils make it noticeably more buoyant.

The Casper Original has distinct comfort zones, which is something to keep in mind. This means that it can provide targeted support to your entire body while maintaining spinal neutrality. The bed’s design also incorporates two different densities of foam: a softer layer near the shoulders, and a firmer layer near the hips and lower back.

Does Casper Mattress Get Firmer?

Depending on how you normally sleep, the Casper mattress may feel firmer. The Casper Original mattress, for instance, has a three-zone design, with softer foam in the shoulder area and firmer foam in the waist and hip areas. The transition layer’s center is also fairly firm, so the Casper mattress may feel firmer if you sleep on your back or stomach and softer if you sleep on your side.

Do You Have To Break In A Casper Mattress?

Casper mattresses, like all foam beds, need to be broken in. Because of how different and perhaps even too firm the Casper mattress will feel on the first few nights, an adjustment period is necessary. Casper estimates that thirty nights will pass before anything happens.

To “break in” a Casper mattress means to use it on a regular basis so that the materials can relax and become more comfortable. Casper also suggests making sure your new bed is oriented correctly, with the Casper logo facing left and legible from bottom to top. In addition, your brand-new Casper mattress requires a firm, flat base.

Why Does My Casper Mattress Smell?

Since the foam used in Casper mattresses is synthetic, they will have a chemical odor when first opened. However, you can rest easy knowing that Casper’s foams are non-toxic thanks to their CertiPUR-US certification. If your brand-new Casper mattress has an unpleasant odor, simply walking on it will help it dissipate.

What About the Casper Wave Hybrid?

Casper Wave Hybrid mattress


The Waves of Casper is a hybrid design that incorporates springs for the kind of additional support that memory foam alone can’t offer. Because of this, the Wave is often the preferred option among those with larger bodies than the typical mattress can support. However, the Wave is Casper’s high-end offering, so expect to pay at least $2,895 for it.


In any case, that’s all there is to it! For the most part, Casper mattresses have a medium firmness. However, the Nova Hybrid is a particularly comfortable bed.

However, the Casper mattress is great for most people because of its medium firmness.
