Casper Mattress Review Overview

The Casper mattress is a versatile and comfortable foam mattress that should be an excellent fit for many different types of sleepers. This mattress is designed with a Zoned Support system that offers more targeted support than the average foam mattress.

The Zoned Support system is a layer of memory foam that is firmer toward the center and softer toward the head and foot of the mattress. This unique design makes the mattress feel firmer or softer depending on what position someone is sleeping in.

Overall, the Casper is a comfortable, supportive, and durable online mattress that deserves its spot at the top of the bed in a box market.

Who Might Like The Casper 

Who Might Not Like The Casper

  • Heavier side sleepers who require a thicker comfort layer
  • Those who prefer a slow-moving memory foam feel
  • Stomach sleepers who need more support under the hips

Casper Mattress Video Review

Anyone who wants to take a closer look at the Casper should definitely check out our in-depth mattress review. Our reviewer, Marten, tests the mattress out for himself and discusses his overall experience with the mattress.


Casper Mattress Firmness And Feel

One of the main things that mattress shoppers should keep in mind is the firmness and feel they are looking for. Let’s talk about just how firm the Casper mattress is and how this will make it feel for different types of sleepers.

How Firm Is The Casper Mattress?

In our experience, the Casper feels like a 7/10, just a tad firmer-than-average, but the firmness of the Casper will depend on the size of the person who is sleeping on it. A larger person might press further into the mattress, so they could feel like the Casper is even firmer; a lighter person might not press in so far and could feel like the Casper mattress is softer.

In addition, the Zoned Support system is going to make the Casper mattress feel firmer or softer, depending on one’s sleeping position. Because the center of the transition layer is firmer than the rest, the Casper will feel firmer when back sleeping and stomach sleeping and softer when side sleeping.

Sleeping On The Casper

Starting off back sleeping, the Casper is a fantastic match for us because our hips sink in just a bit, and we can feel the extra lumbar support from the Zoned Support system. Because of this, Casper is one of the best mattresses for lower back pain and sciatica. Also, the top layer of AirScape foam is offering us a decent amount of contouring.

Casper Mattress - Side Sleeping

Side sleeping, the Casper mattress does feel softer under the shoulders because of the Zoned Support, which makes it a good mattress for side sleepers. The mattress is actually softer in that area, so the pressure relief is quite noticeable.  When we are stomach sleeping, the mattress does feel firm enough for us and, thanks to the Zoned Support, it is keeping our hips from sinking in too far. It is not the best mattress for stomach sleepers we have ever tried, but it is quite supportive.

What Does The Casper Feel Like?

Overall, the Casper features a responsive, balanced foam feel that features a good amount of bounce. The AirScape foam lets us sink in just a bit, but we have no trouble moving around on the mattress, and we never feel stuck. Also, with the Zoned Support system, the Casper mattress will have an uneven feel because it is firmer toward the center.

Casper Mattress - Firmness And Feel

Average Weight Sleepers – 130 lbs – 230 lbs

Average weight sleepers should feel comfortable and supported in all three sleeping positions, making this a great mattress for combination sleepers.  They will get all the support and comfort they need when back sleeping, and all the pressure relief they need when side sleeping. In fact, they will find it to be one of the best mattresses for neck and shoulder pain. Stomach sleeping, they should get enough support under their hips.

Heavyweight Sleepers – Over 230 lbs

A good number of heavier back sleepers should feel well supported when they are back sleeping, and that Zoned Support should provide extra lumbar support. That being said, much larger back sleepers, such as those who are over 275 lbs, will probably want a hybrid or innerspring mattress. See our list of the best innerspring mattresses for some good options.

Side sleeping, larger sleepers might feel like the Casper is too firm, and they could experience heavy pressure on their shoulders and hips. Also, larger stomach sleepers will most likely need a firmer mattress to give them the requisite amount of support. Those who need the best mattress for heavy people should see our roundup.

Lightweight Sleepers – Under 130 lbs

Like average weight sleepers, lightweight sleepers should like the Casper in all three sleeping positions. They should feel supported when back and stomach sleeping, and comfortable when side sleeping. The Casper is actually one of the best mattresses for lightweight sleepers.

Casper Mattress Construction

Now, we will look at the materials and design of the Casper mattress. We will look at each layer one by one and discuss what it does for the overall mattress experience.


The Casper’s cover is thin, soft, and won’t greatly affect the feel of the mattress.

Comfort Layers

The top layer of the Casper contains AirScape, a proprietary foam that is both soft and responsive. It is also open-celled and ventilated to keep the top of the mattress from trapping too much heat.

Casper Mattress - Construction And Foam Layers

Below that, we have the Casper’s Zoned Support – this is a memory foam layer that is firmer toward the center of the mattress, and softer toward the head and foot. As we mentioned above, this will make the mattress feel firmer or softer depending on one’s sleeping position. It will also make it a good fit for people with pain issues and one of the best mattresses for fibromyalgia and the best mattresses for arthritis.

Support Layer

The Casper’s comfort layers rest on a thick layer of supportive, base polyfoam.

Mattress Height

The Casper is 11″ tall, which is an average height for an all-foam mattress.

Casper Mattress Performance

Just how well does the Casper mattress perform when it comes to cooling, motion transfer, and edge support? Well, keep reading to find out!


First off, the Casper is an all-foam mattress, so it is not going to be as cooling or breathable as a latex, hybrid, or innerspring mattress. That being said, it does boast some features that should keep the top of the mattress from feeling extremely hot – the top cover is breathable and the layer of AirScape foam is open-celled and ventilated for enhanced breathability and airflow.

Hot sleepers should also take a look at Casper’s Cooling Collection – it includes the Casper Nova Hybrid Snow and Casper Wave Hybrid Snow.

Motion Transfer

While the top of the Casper is quite responsive, it does feature memory foam in its comfort layer. This material is usually the best at isolating motion, we aren’t noticing too much motion transfer when we lie down and let someone move around on the other side of the mattress. This lets us know that the Casper could be one of the best mattresses for couples.

Edge Support

Sitting near the edge of the Casper mattress, we feel secure enough to lean over and tie our shoes. The mattress also isn’t collapsing too much when we lie down near the edge, and we do not feel like we are going to roll off.

Casper Mattress - Edge Support


The Casper contains some high-quality foams and according to the company, the base layer is particularly durable. Based on this information, the Casper mattress should last for at least seven years of constant use.


The Casper is a bed in a box mattress so, of course, there is going to be some mattress off-gassing. When we first unboxed the Casper mattress, there was a slight chemical smell but, after 48 hours, it did go away.


Given that the Casper is an all-foam mattress, we did not hear any real noise when we moved around or changed positions at night. Noise is much more common with hybrid and innerspring mattresses, but all-foam mattresses like the Casper are usually quite silent.


Mattresses that are more responsive and bouncy are usually better for sex because they make it very easy to move around. Because the Casper mattress has more of a balanced foam feel, sexual partners should have no issues repositioning. In fact, it’s one of the best mattresses for sex.

How Does The Casper Compare To Other Mattresses?

When shopping for the best mattress-in-a-box, it is an excellent idea to compare the different options. Let’s see how the Casper Original stacks up against other Casper mattresses as well as some of its competitors. You can read more Casper comparisons like Casper vs Casper Wave Hybrid and Casper vs Saatva by checking out our mattress comparison page.

Casper Original Vs. Purple Mattress

The Casper and the Purple are two of the most popular bed-in-a-box mattresses on the market, but they feature very different constructions. The Casper is an all-foam mattress with zoned construction, while the Purple features the company’s proprietary gel hex grid.

Purple Mattress - Gel Grid

In terms of firmness, the Purple should feel firmer than the Casper – this will depend on the weight of the sleeper. Larger people might feel the Purple is softer and the Casper is firmer.

These two mattresses are very close in price and are both a good fit for combination sleepers, so it really depends on what feel someone is looking for. The Casper will be a better option for those who prefer a balanced foam feel, and the Purple will be better for those who want a unique gel feel that’s especially durable.

Casper Vs. Nectar

Both Nectar and Casper are all-foam mattresses with an affordable price tag and quality materials. They have a pretty similar construction, though the feel of these mattresses are different. Nectar has more of a memory foam feel while Casper has a softer feel.

Nectar Mattress - Side Sleeping

Both have bouncy, responsive layers, but Casper is softer. Nectar’s slow moving memory foam feel offers more support. Casper is more responsive and less firm than the Nectar.

They are close in price, though Nectar will cost a bit more. While they are made of the same materials, their different feels make these mattresses ideal for different types of sleepers. Casper will be better for side sleepers due to its ability to conform to the body’s curves while Nectar is better for stomach and back sleepers because it is firmer.

Who Should Get The Nectar Mattress

  • Sleepers who like the memory foam feel
  • Stomach sleepers
  • Back sleepers

Who Should Get The Casper Mattress

  • Side sleepers
  • Those who want a softer, more responsive mattress
  • Folks who want a mattress with zoned support

Caring For Your Casper Mattress

While a mattress is an important purchase, it’s not one you want to make often. Prolong the life of your Casper Mattress with these care tips.

How to Clean a Casper Mattress

To clean a mattress, take off all the sheets, comforters, and pillows until your mattress is bare. Go over the entire mattress with a vacuum to remove any dust. Next, spot clean any stains. While Casper says any stain remover will work, they recommend an enzyme-based cleaner on their website.

After you spot clean stains, sprinkle baking soda to get rid of any odors. The longer you leave the baking soda on, the better, though two hours is the minimum time. After the baking soda does its job, vacuum the mattress again and let it air out for 8-10 hours.

Can a Casper Mattress Be Flipped?

The Casper is not designed to be flipped. However, it’s a good idea to rotate the mattress 180 degrees every 3-6 months if you have a significant weight difference between you and your partner or sleep alone.

Do Casper Mattresses Need a Box Spring?

Since the Casper original is a memory foam mattress, it does not need a box spring.

Overall Rating

Casper Mattress
3.5 Overall
Casper is perhaps the best known bed-in-a-box option with a latex over memory foam construction. The mattress is soundly constructed and delivered at great value. It is a solid mattress, but at this point I don't think the mattress (based on specs) really stands out amongst competitors, and isn't currently one of my top picks.
