Casper has made some changes to its design since its initial launch. This review reflects the very latest version of the mattress.
At this point, there have been countless new companies that have entered the space and tried to dethrone Casper as the king of the online mattress industry. However even with crazy mattress competition, Casper has still managed to stand apart in my mind as a top mattress in the industry, and has ended up being one of my very favorite mattresses on the market (which for a guy who has tried 70+ mattresses over the last few years, is saying something).
Though it’s not necessarily the right choice for every mattress shopper, Casper is definitely worth a strong look if you’re looking for a new mattress.
Who Should Be Interested In Casper?
- Back/Stomach Sleepers– The mattress is slightly firmer than average in my opinion. It does a good job of conforming to the natural curves of your body as well, so I think it’s a good option for back or stomach sleepers.
- Middle Weight Range Side Sleepers– If you are not overly light or overly heavy, I think you’ll find the pressure relief of the Casper to be very good. The comfort foam and memory foam combine to have nice pressure relief.
- Value Seekers– You save a ton of money by going with Casper versus a comparable mattress found at a retail store. It offers great value over retail store alternatives.
- You Want Some Bounce/Resilience– If you want pressure relief but don’t like the slow-moving feel of just memory foam, the Casper could be a good choice. It has good resilience, which makes it easier to move around and switch positions in bed.
Why You Might Not Want A Casper
- You Like The Innerspring Feel– The feel of the Casper is different from the standard innerspring / foam. If you really like that feel, then maybe you will want to look elsewhere. I personally still had a great experience with Casper, but it’s at least something to note.
- You Love The Pure Memory Foam Feel– Memory foam has a very distinct feel. The Casper is much more resilient and bouncy, so if you absolutely love the memory foam feel, you won’t quite get that here.
- You Have A Really Small Or Really Large Budget– Casper claims to be the one perfect mattress, but if you want a mattress to last only a few years and don’t want to spend that much money on it, there is no reason to pay extra for a Casper (something cheaper like the Tuft And Needle may be more appropriate). Similarly, if you have a big budget, you can find better ultra-luxury mattresses out there.
- The Mattress Does Sleep Cool– In my experience, the mattress did sleep very cool. If you live in a warm climate, this can be very key to a good night of sleep. Putting latex over memory foam was definitely the right decision. When I decided to review the Casper mattress, I paid special attention to this knowing memory foam was a big part of the construction.
- Still Waiting On Long-Term User Data– The company is still very new, so we can’t really say for sure just yet how the mattress will hold up for the long-term. Sometimes foam mattresses can sag over time. I don’t think that will be the case here, but again it’s too early to say for sure.
- Super Friendly Customer Policies– The free trial and return policies are top notch and definitely alleviate any concern of buying the mattress online.
- Zipper– The mattress has a zipper. You can take off the cover and wash it if you want. It’s a nice little extra to have in my opinion.
Sleeping Position Suitability
- Stomach Sleepers– I think the Casper is a good match for stomach sleepers. It’s slightly firmer than average and relieves any pressure you might have on your front side while sleeping.
- Back Sleepers– I also think the Casper is a good match for most back sleepers. It does a nice job of conforming to the curves of your body and is slightly firmer overall.
- Side Sleepers– For people who are really lightweight, I think the mattress might be a bit too firm. For people who are really heavy/obese, you might push through the comfort layers and hit the firmer layers beneath them, and you would thus think the mattress is a little too firm. It should be a good match for side sleepers of average weight.
The video below gives a good visual overview of the different layers and specs of the mattress. Here is also a quick overview of the different layers:
- The cover is a lightweight premium fabric. It’s pretty stretchy and I find it to be breathable and high-quality overall.
- The top layer is 1.5 inches of a specialty polyfoam the company calls comfort foam. It has a lot of the same qualities as latex. Namely, it is breathable and has good bounce to it.
- The next layer is 1.5 inches of 3.5 lb. density memory foam. This layer allows the mattress to conform well to the curves of your body and provides good pressure relief.
- The next layer is 1.5 inches of polyfoam with a 2.5 lb. density. This is a transition layer to help people go from the comfort layers to the support layer more smoothly.
- The base layer is 5 inches of polyfoam with a 1.8 lb. density. This is a fairly standard base foam that you will see in a lot of other bed-in-a-box mattresses.
How To Care For The Casper Mattress
Casper says one of the best ways to care for your mattress is to take preventative measures to avoid spills, stains and other potential damage.
Here are some tips Casper provides to caring for your mattress:
- Use a waterproof mattress protector to avoid stains, spills and other accidents
- If you do have an accident spot clean the cover of the affected area as quickly as possible with an enzyme based cleaner. To get deeper set stains, use a laundry brush paired with the cleaner
- Air out your mattress by ditching the sheets and opening a window. If it gets smelly, sprinkle baking soda on the cover and vacuum it off
- Clean your mattress every time you rotate it (180 degrees every 6 months)
- Take it to a professional mattress cleaner if necessary
Note that the mattress is not designed to be flipped / turned upside down.
The video below shows off the general feel of the Casper. You can see that there is a good amount of bounce to the mattress. It’s not as bouncy as a pure latex mattress but it is quite resilient. You can also see that the mattress is just slightly firmer than average.
The video below shows how well the Casper does with motion isolation. As you can see, it does perform pretty well, making it a good option for couples who are worried about being disturbed by their partner’s movements in bed.
- Casper offers a 10 year limited warranty with their mattress. It is only available to the person who originally purchased the mattress, you can’t transfer it if you sell it or give it to someone so make sure you keep the original receipt.
- As long as you use the mattress for its intended purpose and place it on an appropriate base, the warranty will cover any defects in material and workmanship.
- The “defects” cover a variety of things ( we encourage you to read the fine print yourself) including issues with splitting/cracking, sagging more than 1-inch and defective zippers.
- The warranty does not cover you if you decide the mattress is too firm/not firm enough. If you do something abusive or damage the mattress in some way you’ve voided your warranty.
Bottom line: treat your mattress well and read the mattress warranty so you know exactly what is covered and not covered.
Changes From Initial Version
- The new version has a 1.5 inch transition layer (which the original version did not have). This was added so that there would be a smoother transition from the comfort layers to the firmer support layer.
- The original version had latex in the top layer. That has now been replaced by a specialty polyfoam that the company calls “comfort foam.” It has a lot of the same qualities as latex and in my opinion made this version very slightly softer.
- I believe that the 4 layer design, in addition to the other tweaks/changes the company has made, means that the layers work well together and are a better fit for more people now. Pressure relief is better now for people of all body types. I also think the new design is more breathable than it has ever been.
Free Trial Period And Return Policy
The Casper mattress comes with a 100-night trial. The trial starts the day you receive the mattress.
This trial period is a part of Casper’s return policy. If you decide to return the mattress you need to contact the folks at Casper directly. They will work with you to arrange a time to pick it up and refund you in full.
Casper won’t resell your mattress, so they may connect you with a recycler or someone who can take the mattress away or donate it to charity, as opposed to bringing it back to the company.
Do not try to squish the mattress back in its original box and packaging. Just remove the bed linens and try to make it easy for the couriers to retrieve if possible.
Exchanges are available for all Casper products during the 100-day trial as well . If you want to exchange the mattress, you can send Casper an email.
What Bed Types Does It Work On?
The mattress will work with all standard foundations (including adjustable bases), just make sure you have as much direct support under the mattress as possible. Not supporting your mattress properly may void your warranty. You can even use the Casper on the floor if you have to.
According to Casper, the best option for the mattress is to have it on the Casper foundation and metal bed frame. However, a wooden slatted or platform bed will offer good support as well (as long as the slats aren’t too far apart).
If you already have a boxspring or foundation and you don’t want to buy something else, Casper suggests you get a bunkie board (a thin platform that adds support) for the space between the mattress and box spring.
In Casper’s words: the firmer, the flatter, the better.
The video below shows that the mattress works just fine with an adjustable base.
As with any foam mattress, the edge support isn’t that great. The picture below shows off what it looks like when I sit on the very edge of the mattress. You can still use most the sleeping surface of the mattress, but you may need to go with an innerspring mattress if edge support is a big factor for you (and it’s not for most people).
Shipping and returns are free of cost for customers. They will ship to the United States, Canada, Germany, Austria, Switzerland and the United Kingdom.
Regardless of size, all Casper mattresses ship in their standard box of 19” x 19” x 42”. The total weight of the box ranges from 44 pounds to 110 pounds.
If you are in the United States, UPS will deliver your mattress from a warehouse partner.
Casper gives options to dispose of your older mattress if you live in New York City, Los Angeles, San Francisco, San Diego, San Jose, and Seattle.
You will need to unbox and set up the mattress yourself unless you live in n New York, Los Angeles, Chicago, and San Francisco, in which you have the option of using Casper’s White Glove Service.
Once you get wrapping off the mattress, it should inflate very quickly. Give it 24 hours to fully inflate.
The White Glove courier will deliver your mattress at a preferred time, unboxed it and remove any extra packaging you may have. They may also be able to remove your old mattress.
The table below shows the weight of every size of the Casper, with just the mattress and also including the weight of the box.
||Weight (Just Mattress)
||Weight Including Box
Casper claims there is no weight limit and hasn’t tested any weight where the mattress doesn’t stop providing support. If you are over 350 lbs., however, I would recommend finding a mattress specifically catered to higher weight people.
Is There A Chemical Smell?
Like really any other foam mattress that arrives in a box, there will be a slight chemical smell/odor when you first unbox the Casper (commonly called “off-gassing”). This is completely normal and nothing to worry about at all. You will want to let it air out initially and then the smell should be completely gone within 48-72 hours.
Does It Sleep Hot?
In my experience, the mattress did not sleep hot. This is mainly because the memory foam layer is not on top. There are probably other mattresses out there that do an even better job of sleeping temperature-neutral, but I think in the case of Casper, most people will not have any issues with sleeping hot.
Is It Eco-Friendly?
The foams used in the Casper are Certi-PUR certified. That means there are no toxic or harmful chemicals used in the construction of the mattress. If you want something that is organic, you would have to go with a natural latex mattress, but those are going to be much pricier.
