Everybody who knows a thing or two about the most popular mattresses has heard about Casper. Launched in 2014, Casper is now one of the industry’s most recognizable brands. As a bed-in-a-box company, they sell their products primarily online. Once you order the mattress, it will arrive at your door compressed and rolled up in a box. 

One of their most exciting offerings is the Casper Sleep Mattress. It’s a comfortable and supportive model that accommodates all sleeper types. Like most beds of this type, this one also sports several layers of foam. Altogether, they measure 12″ in thickness and work together to provide comfortable, undisturbed sleep. 

In our review of Casper mattress, we’ll take a closer look at each feature of this bed. Besides the construction and overall feel, we’ll also analyze the model’s cooling, motion transfer, and edge support capabilities. Furthermore, we’ll examine how easy it is to keep it clean and check out any extra considerations. 

If you’re looking for a comfortable all-foam mattress, this may be your best option. Although not cheap, the Casper bed justifies its price by offering ultimate comfort and support, which is excellent for people will arthritis. Our Casper Mattress review will help you determine if this model is the right choice for your bedroom.

Casper Bed Features

The Construction

Twelve inches thick in total, the Casper Bed consists of four distinct layers. They vary in thickness, density, and purpose. All of them are wrapped with a durable polyester cover. Like most mattress covers, the cover of the Casper should be spot-cleaned only. 

The first layer of this bed is 1.5 inches thick. Using open-cell foam it prevents the sleeping surface from overheating.  It’s the model’s first comfort layer and the one that gives it some bounce. The second layer sports the same thickness. It is, however, denser, and therefore provides motion isolation and pressure relief. 

The most innovative part of this bed is its third layer. It uses proprietary Zoned Support foam. In other words, it comes with special areas that provide extra pressure relief for one’s knees and shoulders. It also serves as the transition layer between the base and the second layer. 

Finally, the base of Casper is 7″ thick and uses high-density foam. It’s the foundation of the mattress, lending durability, as well as additional support. 

While simple, this construction works well and makes the model comfortable to sleep on. “Zoned Support”, on the other hand, provides extra support in specific targeted areas.

The Feel

Unlike most beds of this type, the Casper mattress offers slightly less sinkage. This will be very convenient for back sleepers. As an all-foam bed, Casper isn’t particularly bouncy. This is mostly due to its base and top layers. 

However, even weight distribution is guaranteed. Thanks to the Zoned Support, the sleeper’s spine is always in correct alignment. This is because of the firmer transition foam located under the user’s hips. Overall, the model provides a gentle cradled feeling, relieving pressure where necessary.

With Casper, you’ll never feel like you’re stuck. Rather than sleeping “inside it”, you’ll feel like sleeping “on top” of it. The model’s base, transition layer, and the quick-response top allow quick position changing. Since it balances alignment and comfort so well, this model is ideal for combination sleepers. It’s also suitable for side sleepers

The Casper Bed is undoubtedly one of the most versatile models we’ve analyzed so far. It stands as an excellent choice for a broad variety of people and body weights. We scored it as a 6 on our mattress firmness scale.

Motion Transfer & Edge Support

When it comes to motion isolation, foam mattresses shine the most. This is because they tend to isolate movements by absorbing shocks. The motion isolation of the Casper mattress is comparable to other similar models. While somewhat bouncy, this mattress successfully prevents motion transfer across its surface. 

Why would this be important to you? If you have a sleep partner, you probably hate being woken up by his or her movements. A bed with good motion isolation prevents this from happening. Combined, Casper’s motion isolation and medium firmness make it an attractive option for couples

The edge support of Casper Sleep is just as good. Lying close to its edge doesn’t produce the feeling of like you’re going to roll off. Sitting on the edge does produce some compression, however. Still, even with your weight concentrated on one spot, the model will keep you supported

Edge support is undoubtedly a feature all couples must consider. Sometimes, your partner will sleep in the middle, with you being confined to just one side of the mattress. When this happens, you don’t want to roll off the bed in the middle of the night. With the Casper bed, that will never happen.

Temperature Regulation

Most bed sellers tend to equip their mattress with cooling capabilities. Overheating during sleep is never a good thing. Sometimes, it can prevent an individual from experiencing REM sleep. As you already know, REM sleep is when most restorative processes take place. 

For that matter, temperature regulation is always an essential consideration. It should be particularly important for people who tend to sleep hot. Memory foam is not the best material in this regard. The conforming nature of this material absorbs and retains heat, restricting airflow in the process. 

However, the Casper Bed uses open-cell foams. These come with tiny pores, allowing excess hot air to escape. Combined with strategic layering, these proprietary breathable foams keep the sleeper cool. Although not the coolest mattress out there, Casper does well in the temperature-regulation department. It sleeps cooler than most of its rivals in the same price category. 

If you’re a really sweaty sleeper, however, consider purchasing an innerspring mattress. Unlike foam models, these absorb only a small amount of body heat. This is mostly due to their support cores. As they consist of steel springs rather than foam, they help the mattress stay cool. This is also an excellent choice for heavier people, as it is one of the versatile models on the market.

Cleaning & Safety

The cover of the Casper mattress is fully removable. Moreover, it fits quite well, so you won’t have to worry about it bunching up under the sheets. 

Although it can be removed, we advise against doing so. This is because the manufacturer doesn’t offer definitive info if it’s machine-washable or not. They say that it’s easy to clean, but don’t mention anything about washing machines. 

In case of an accident, we recommend spot cleaning. Take a mild detergent, some warm water, and then dab at the spot. Try to avoid getting the spot too wet – you don’t want water soaking into the layers below. 

Off-gassing is quite typical with foam beds. Most of the time, it’s the result of synthetic materials or plastic packaging. Fortunately, the Casper Mattress uses water-based adhesive. Furthermore, all of its layers are CertiPUR-US certified. In other words, they contain no harmful toxins. 

Once you unpack the model, you’ll probably notice a strange odor. Don’t worry about it too much. It’s not dangerous, and it will disappear after a couple of hours. Make sure to unpack the mattress in a well-ventilated room.

Other Considerations

As an established industry, the online mattress industry follows a couple of standard policies. These include a 10-year warranty and a 100-night trial period. Of course, this varies from one company to another. 

Fortunately, Casper follows these standards completely. A 10-year warranty accompanies the Casper Sleep. Moreover, you’ll have 100 nights to try it out. If you find it inadequate to your needs, you can simply return it. The company offers free returns and full refunds. 

Setting up this mattress is exceptionally easy. It takes only a couple of minutes to get everything ready to go. Don’t forget to let the model sit out for 24 hours. This will give it enough time to off-gas and decompress.
