Editorial disclosure: We get a commission from Casper when you make a purchase through the links or with the coupon code in this post.

NYC-based Casper was founded with the goal of improving sleep and modernizing the industry, and they’ve been popular with consumers from day one. In fact, they sold out of their original mattress within 24 hours of going on sale.

Since then, they’ve raised $240 million in funding—including from celebrity investors like Toby McGuire, Adam Levine, and Leonardo DiCaprio—which is a lot of money for making a great mattress. They’ve also gathered millions of data points and created an in-house R&D team, called Casper Labs, where this information is transformed into real-world products.

In 2017, the company’s original mattress (which one of our staff members and their spouse purchased about a year and a half ago, and continue enjoying today) was updated and improved with:

  • A 1.5” top layer for added comfort when transitioning to the firmer support layer
  • A latex-like polyurethane foam labeled “comfort foam” by Casper, which aims to add softness
  • A more breathable design that’s likely to provide effective support for a broader cross-section of sleepers

The bottom line is that when it comes to buying a mattress, there’s no replacing personal experience. In other words, you need to sleep on one for at least a month before deciding whether or not it meets your needs.

To help you decide if it’s worth placing an order and taking advantage of the company’s 100-night trial, though, we had the opportunity to sleep on the Casper mattress over the course of eight nights, which we received for free from the company. What follows is our experience.

How Much Does the Casper Mattress Cost?

Casper's full-size mattresses start out at $1,050, while a queen costs $1,195 and a king is priced at $1,495. Six, 12, or 18-month financing is available through Affirm, with APRs ranging between zero and 30 percent.

Regardless of the size, all orders include free shipping and a 100-night trial. Basically, if you’re not satisfied with the mattress, they’ll arrange for free pickup, which we think is pretty awesome.

Our Casper Mattress Set Up

Our mattress arrived in a moderately heavy box (not as heavy as the Casper Wave, though), but we think most consumers could set everything up by themselves, depending on their strength, of course. (Our tester was 6’ 5” and 260 lbs.)

Casper Mattress BoxThe Casper Mattress arrived in the box shown above, we recommend two people, although possible with one.

After pulling the mattress out of the box, placing it on a foundation, and cutting the plastic, we watched it unfurl and expand over the course of about five minutes. Then, we were ready to go.

After this super easy setup, in our opinion, we think Casper’s mattress had a sleek, aesthetically pleasing design in plain grey. Nothing too fancy.

We did notice a light odor when we cut open the mattress’s plastic, but it wasn’t strong enough to keep us awake or bother us in any way, and it completely dissipated over the course of three to four days.

What Did We Learn About Casper Mattress’s Construction?

We cut the cover on our mattress to check out its four layers for ourselves, which combined (including the breathable zip-off cover) to deliver an overall height of 10 inches:

First Layer: Comfort/Latex-Like Foam (1.5”) – A proprietary, open cell layer that gives the mattress some bounce and breathability to prevent you from overheating.

Second Layer: Memory Foam (1.5”) – Provides a pressure relieving, contouring feeling to your body.

Third layer: Zoned Support Transitional Layer (1.5”) – This is a unique technology created by Casper that promises to deliver “incredible comfort, ideal anatomical support, and focused spinal alignment.” Here, the foam underneath the shoulder area is softer, allowing them to sink in, while the hip and core-area foam is firmer for added support and spinal alignment.

Fourth layer: Dense Foam Foundation (5”) – Made of high-density poly foam that provides the mattress’s foundational support.

Casper Mattress Comfort Level: Firmness & Weight Distribution

On a firmness scale of one to ten, with one as the softest and 10 as the firmest, we think the Casper mattress rates somewhere near a seven. Which is obviously a little on the firmer side, but as someone who suffers from chronic back pain, something we actually prefer.


Each time we laid on the mattress, we noticed a sinking feeling for a second, followed by a distinct firming as the foam contoured to our body.

We found weight distribution was consistent throughout the entire mattress, with no noticeable soft spots. If you’re an edge sleeper, you’ll almost certainly find this mattress can accommodate your preferences.

Speaking of which, we prefer sleeping on our side, and found the mattress perfect for that as well. Even when occasionally watching Netflix in bed while laying on our back, we could imagine that sleeping in this position would be equally as comfortable.

We think it might be perfect for any sleeping position, really (more in a second).

To test motion transfer, two participants laid on the mattress together and took turns moving and getting up and down, while the other lay still. There was no noticeable movement—at least, not enough to wake someone up in the middle of the night, unless they’re an especially light sleeper.

As mentioned earlier, we suffer from chronic back pain. And while the Casper mattress didn’t do anything to make it worse, it also didn’t make the situation any better, either, which is a huge plus in our mind.

On the other hand, we did find that the Casper Wave took away some of our back pain.

Does the Casper Mattress Sleep Hot or Cool?

As most of us know, temperature plays a huge role in how well we sleep. In other words, if you’re too hot or cold, you’ll frequently wake up, rarely reach deep sleep, and often be plagued by grogginess the following day.

In this regard, we thought the Casper Mattress did a good job of maintaining temperature balance. Although we felt it was a bit on the warm side for our taste, but again, that could be due to our tester’s size.

We also prefer to sleep with our window open, and with temperatures currently the mid-40s here at night, that might have played a part in how warm we felt.

What’s Our Bottom Line About the Casper Mattress?

The Importance of Your Sleeping Position When Buying a Mattress: During our past research into the online-only mattress industry, we’ve learned that—in general—the ‘best’ option for anyone is largely going to come down to preferences. Specifically, your preferred sleeping position.

For example, side sleepers tend to go through a mattress’s comfort layer faster than other positions, so they often prefer models with thicker top layers. Mattress Clarity adds that side sleepers are most in need of pressure relief around the hip and shoulder areas, making a thicker, softer top layer even more crucial.

With this in mind, the five unique layers and between 36 and 38 polymer support channels found in their Wave mattress provided us with more contoured support in these regions, which might better suit side sleepers—especially for those who suffer from chronic back pain, which we also do.

On the other hand, back sleepers tend to prefer a thinner top layer (two inches or less). Stomach sleepers might prefer the same, but the top layer typically needs to be firmer in order to prevent the back from curving backward unnaturally.

And while we didn’t test the Casper on our stomach, we might imagine its four-layer design—including the recently added Zoned Transition Layer—and medium firmness would be ideal for all sleeping positions. Those who sleep hot, regardless of their preferred position, might also prefer its thinner design.

Who Might the Casper Mattress Work Best For?

After sleeping on the Casper mattress for more than a week, we woke up feeling rested each morning, without any excessive back pain.

Furthermore, we found it comes at affordable prices, ships directly to your door, comes with a 100-night trial and free pickups, and can be set up and ready to deliver a good night's sleep in about five minutes. Together, we think the company is clearly doing a great job with their mattresses, and we feel comfortable recommending them to our family, friends, and readers.

Factoring this into all of the details discussed above, we think Casper’s seven-out-of-10 rating makes it an ideal firmness for almost any sleeping position, whether side (like us), back, stomach, or combination. In other words, based on our experience and the company’s reputation, warranty, and quality, we feel you can’t go wrong with a Casper mattress.

Just keep in mind that your pillows can play a role in how well you sleep, so don’t forget to factor those into the equation as well.

    You will be impressed

    • Ann Arbor, MI,
    • Nov 19, 2014

    About 6 years ago I purchased a luxury pillow top mattress that I thought was amazing when I first got it. Over the years it degraded to one of the most uncomfortable beds you could find. I was looking forward to hotel stays just to get off of our mattress. We decided we need to upgrade. With a lot of friends going the memory foam route and loving it we went to the store to try some out. We liked them for the most part but hated the idea of paying over $2000 for a mattress. I started researching online and found Casper. I was very skeptical at first. It was less than half the price we were looking at paying and we couldn’t test it out before the purchase. After weighing some options I decided to give it a go and ordered a queen. The ordering process was super smooth and shipping took only 2 days to Michigan. Unpacking the mattress took about 15 minutes and it was ready to lay on.

    First impression – The Casper has an initial feeling that is more firm than most memory foam mattress we tried in the store. However once you lay on it for a minute it cradles your body nicely. I assume this initial firmness it provided by the latex top layer, than the memory foam 2nd layer cradles you. It does have a light smell at first but only noticeable if your nose is right at the mattress. 

    Here's a one-month review:

    1. I am noticeably getting better sleep on the Casper than my old mattress. My old mattress was terribly so perhaps any mattress would have been better….but so far the Casper is delivering.

    2. It is a very cool sleeping experience. I am hot all the time and would frequently over heat on the old pillow top. So far I have notice the Casper is cool to the touch when getting into the bed and maintains a lower temperature through the night. This is a big bonus for me.

    3. Its still springy! One thing we did not like about the memory foam mattresses is when you try to move or roll you almost need to lift yourself up out of the mattress than move. On the Casper you can just move naturally. It has far less sink then most other foam mattresses.

    Overall if you are looking for a firmer feeling and cool sleeping mattress I would recommend the Casper 100%. If you love sinking down into a plush memory foam mattress, this is probably not for you. The only downsides I have noticed so far is the edge stiffness is low. If you sit on the edge of your mattress a lot this might be an issue. Also at only 10” thick (compared to our 18” pillow top) it might change your bed height a decent bit.

    Give Casper a shot and you won’t be disappointed.

    Under whelmed

    • Los Angeles, CA,
    • Jul 20, 2015

    I was super excited after all the hype, but then I actually slept on the bed. It is kind of stiff and not that comfy. They make you keep it for longer than you want when it's not comfortable, which is a bummer. In the end, it went to a local donation station and I got my money back.

    I found the perfect bed

    • Port Huron, MI,
    • Nov 18, 2015
    • Verified Reviewer

    For quite some time I knew of the elusive “Casper” but had no idea they were a mattress company. In fact, I followed them on Twitter and believed them to be a brilliantly witty cynic or two sitting around in a dimly lit room lamenting the daylight and sharing scholarly articles about the detriments of sleep deprivation and the superiority of those of us that are quasi-nocturnal.

    However, after sending a friend of mine a barrage of their more hilarious tweets (do yourself a favor and follow them), he asked me if I had “ever looked into buying a Casper.” Considering the fact that I believed Casper to be a small, cynical hipster collective, I was confused about how I would go about owning one and really whether the question was even PC. Then I finally looked past the brilliant quips and discovered that this “Casper” was in fact a company that claimed to have created “the perfect mattress.”

    As someone who struggles nearly every night to fall asleep before it’s technically already morning, I am a sleep enthusiast. In fact, there are days that I wake up already scheming how I could sneak a nap and jealously counting the hours until I could once again be in my bed. In addition to the problem I faced of actually falling asleep at night was the one of my mattress. It was, in a word, nightmarish. Imagine a sleeping surface that was in one spot soft, another lumpy, and – ouch! – there’s a spring.

    So, intrigued by their claim to have manufactured perfection, I decided to look into it further. That’s when I became even more impressed. They were selling this perfection at a reasonable price – especially if it actually did the seemingly impossible and helped me sleep. Then came the best part – well best TWO parts: 1. they offer payment plans that make the mattress very affordable, even on a budget and 2. they have a 100 night trial (and 10 year warranty). So, if on night 99 of sleeping on it I decide that I am just not that impressed, I let them know and they swing by, pick it up, and refund me 100%.

    That’s when I knew I had to give it a shot. I ordered my Casper and then began the waiting process. During this time my archaic and obnoxiously imperfect mattress seemed even more torturous than it had before, and the day *the box* arrived, I all but threw it out a window.

    Unboxing my Casper was a nearly magical experience. As it unfurled in all it’s not too hard, not too soft glory, I felt an affection that I had never expected to experience towards a mattress. But, then again, it’s not *just* a mattress. Sleeping on it that first night, I finally understood what they meant when they claimed that it “lovingly contours to your body.” Unlike memory foam with its manipulation and abuse that molds to your body but then traps you in one position for the remainder of your stay, it holds you ever so tenderly but knows to let you go, free to readjust. Casper accepts you in whatever position you come in and just makes you better. It IS the perfect bed.

    The longer I own this mattress, the more I love it. In fact, as I lay on it typing this post, I have one thing to say: stop reading and go buy your own. You have nothing to lose and so much to gain.

    Go buy the perfect bed. You won’t regret it. Although, even if you do (who ARE you?), just return it within 100 days – no hassle.

    Gave me horrible back pain, not a thick mattress.

    • Bristol, CT,
    • Jan 11, 2015

    First of all, they don't really disclose the fact that it's a SHORT Mattress. I was used to sleeping on a 13 inch thick mattress and this is maybe half of that! Second, it's way too soft. I wake up in more pain than before I got it. Disappointing purchase.

    I won't bore you with unnecessary details regarding our miserable sleep history. Suffice to say that my husband and I absolutely love our Casper. It was an odd and unexpected gift from my Father in law. I (we/everyone!) have listened to my husband complain for 20 years about every mattress we have ever owned (many), and in the month since our Casper arrived, not a single negative comment. It's literally a race to bed every night. I will admit that it was not love at first sight so much for me. In fact, I refused to get rid of my old mattress and had it leaning against the bedroom wall "just in case" for almost 2 weeks. It took me a little over a week to get used to the feel of it - not too soft, not too firm - but, I'm now head over heels as well. It's great support, but, doesn't engulf you like other memory foams and I find it to not be as hot as my old (much more expensive) foam mattress. It's honestly the best sleep I've had in years and the old mattress is just a distant memory now. We are so pleased that we are buying 2 queen size Caspers for our teenage sons.

    Great mattress - finally great sleep

    • Grand Island, NY,
    • Feb 2, 2015

    Have had my Casper Mattress for a week now. I bought it directly from the Casper website, not Amazon. I was I bit worried having a mattress delivered without having tried it. Their 100 day money back guarantee and 10 year warrantee, along with the numerous positive reviews that I found on the internet convinced me to give it a try.

    It arrives folded up in a rectangular box. Wow, how can this be? Will come out of the box and actually be a comfortable quality mattress? I was a bit skeptical. However after unpacking the mattress and giving it a few minutes to decompress it was obviously a smooth and comfortable looking queen size mattress. I laid on it and it seemed comfortable. Made the bed with my regular sheets and blankets. That night I laid down and noticed that no matter how I laid, that I didn't get uncomfortable. With my old mattress lying on my left side would cause discomfort after a while. I thought that it was just me getting older and being in less than great shape.

    I had also gotten into the habit of not needing to set an alarm on the weekends. During the week I wake to my alarm at 4:15 AM. On the weekends I was waking without an alarm between 6:30 and 7:00 AM. My first morning awaking after sleeping on the Casper was at 9:59 AM. What! I had just slept to 10:00 AM! The next morning my wife woke me at 8:30 AM. I now need to set an alarm if I want to wake early on the weekends.

    On my old mattress I would have instances of remembering having been slightly awake while turning over during the night. On the Casper this has disappeared. I sleep soundly through the night. I have had it a week now and can find no issues with the Casper mattress. I love it. It is comfortable to sleep on in all positions. I suggest ordering it directly from Casper to save money.

    Like I said, you have nothing to lose. 100 days to change your mind and get your money back. No you don't have to send it back, they donate it to a local charity in your area that will pick it up. I was interested in a memory foam mattress but didn't want to spend big money for the big name brand.

    I also had read that sex on the big name brand was hampered by the lack of bounce. Casper claims to have gotten around that issue. In the name of science my wife and I tested it out. Things went very well, so that's not an issue. Casper also has gel in their foam to get rid of the memory foam issue of retaining heat. No heat issues for us either. I highly recommend the Casper Mattress.

    We love our Casper, got a great discount

    • Providence, RI,
    • Jul 15, 2015

    I absolutely love this mattress. The customer service, speed of delivery, and quality of mattress are outstanding.

    I am 6' 2", about 190 lbs. I have always had a difficult time finding a mattress that is supportive enough but not overly firm and uncomfortable. I think what is unique about this bed vs some other memory foam beds that I have used is that it remains very supportive under my lower back, in any position. My old mattress would lead to lower back pain in the middle of the night, whereas this mattress eliminated that from the start.

    I would highly recommend this mattress to anyone, and have referred multiple friends/family towards Casper. I do not work for them, but always try to refer people towards companies with quality products and great service.
