Cocoon Mattress Review
Welcome to our Cocoon by Sealy review where we discuss the pros and cons of Chill (and Classic) memory foam mattress
The Sealy Cocoon Chill mattress is one of the best cooling mattresses under $1,500. It’s great for people who enjoy the feel of a memory foam mattress, but tend to sleep hot. This bed will be supportive and pressure relieving, which means it should be comfortable for people regardless of their preferred sleep style, but should be especially comfortable for back and stomach sleepers.

Our YouTube Review Of The Bed
For anyone that’s more of a visual learner, here’s our video review of the Cocoon mattresses—we make sure to discuss the Classic and Chill models.
If you’re still searching for answers, keep reading because we have an extensive written review below. We discuss everything from design to feel and firmness to sleeping positions.
Sealy Maintains Consumer-Friendly Policies
Cocoon comes with a standard 100-night free trial. If you don’t find the mattress to be as comfortable as you’d hoped once it arrives, Sealy will allow you to exchange the mattress one time at any point during the 100-night free trial. Specifically, you can swap out the “Cocoon Soft” version for the “Cocoon Firm.” You can also get a 100% refund if you’d like within that 100-night trial period.
Sealy also offers free shipping on the Cocoon Chill and Classic. They make it quite easy on you, too! Once the bed has been ordered, it will be shipped to you via UPS ground for free. Sealy will send you a tracking number, so you can watch your new mattress journey to your bedroom. Then you just have to unbox the bed, watch the mattress inflate, and enjoy.
Cocoon comes with UPS Standard Shipping (which means the bed should arrive in 5-7 days). However, Sealy offers Saturday delivery, UPS Next Day, and UPS Second Day delivery, depending on where you live. Sealy does not offer international delivery as of this post. However, they say they are planning on offering it for Cocoon soon. So, if you live outside the United States, Sealy says to send them a note and let them know where you’d like them to ship.
If you decide your mattress is not the right fit for you for whatever reason, call Sealy at (888) 818-4039 or email them at email@example.com. If it is during the 100-night free trial, you can return or exchange the mattress for free. If that’s the case, Sealy will arrange for pickup. This may include donating, recycling, or disposing of the mattress. Once the return is confirmed, Sealy will issue a refund to your credit card within 1-2 business days.
If you are concerned about your mattress lasting for a long time, Sealy offers a 10-year limited warranty on Cocoon Chill and Classic mattresses This means that within ten years from your purchase date, they will replace or repair any defect that is covered under warranty. Defects that fall under Sealy’s warranty include any visible indentation greater than 1”, a torn mattress cover, and so on. Make sure you read the warranty details on the Cocoon by Sealy website, because there are a lot of warranty specifications.
Cocoon Chill vs Classic
We mentioned that the Chill mattress is available in a Soft and Firm model, but we didn’t discuss that there’s a Classic model that’s more affordable than the Chill. The big difference between the two is that the Chill has the phase-change cover and the Classic does not. Also, the Classic tends to be about $50 more affordable than the Chill, though, the discounts do not appear to be able steep for the Classic.
The reason that you might get the Classic over the Chill is that you (a) want to save as much money as possible and (b) you don’t really care about the cooling cover. We could see some people making this calculation and ending up with the Classic, particularly if the cover is deemed unnecessary. The only thing that you should be aware of is that the Classic will then sleep warmer than the Chill, so if you have temperature concerns, you might want to just play it safe with Cocoon Chill—especially since you can still return it inside the trial period.
Price Of The Sealy Cocoon Mattress
Cocoon Chill by Sealy mattress is one of the most affordable cooling mattresses on the market. It’s priced similarly to Casper, Leesa, Bear, and many of the other popular online mattresses. The pricing breakdown is as follows for the Chill model:
|King / Cal King||$1,149|
We were able to secure an exclusive coupon code for you. It should be on the right side of your screen or you can check CocoonbySealy.com to see current offers and bundles. As you might imagine, they offer steeping discounts during major holidays. Typically they’ll end up throwing in a pillow or some small sleep accessory with your purchase of a mattress. You can also check out our Mattress Deals & Coupons page to see what promotions we spotted today.
Foam Construction For Soft And Firm Models
Both Cocoon mattresses have a 10” height profile and are constructed with multiple layers of foam. The Chill model is cool to the touch, thanks to its phase-change cooling cover.
The construction of the mattress will depend on whether you get the Soft or Firm model. The Soft model has three layers, while the Firm model has only two layers.
The base layer is made with a dense polyurethane foam. You’ll see this on nearly all foam mattresses. It’s responsive, but given how dense it is, the foam is not pressure relieving, nor should it be since it’s the foundation.
If you go with the Soft model, you will get a transition layer, which, as you’d expect, helps soften up the mattress. What Sealy does is reduce the thickness of the base layer to allow for a transition layer, which is a softer poly foam. The less you feel of the the dense, firm base layer, the softer the bed will feel. The image above shows you the soft model—you can see the three-layer design. There are plenty of foam mattresses that are built like this. For example, Puffy used to be just two layers, but they’ve since added a transition layer in the middle so that sleepers don’t feel the foundation as much.
If you get the Firm model, you lose the transition layer so that you feel more of that dense support foam. The thickness of the mattress remains the same, however. In both cases, the Cocoon mattress is 10″ thick. Below is a construction shot of the Firm model. You can see the dense foundation on the bottom and the memory foam on top. It’s pretty simple—just poly foam and memory foam.
Irrespective of which model you go with, the top layer is made with 100% memory foam. As is typical of memory foam, this layer will adapt to your body size, shape, and sleep position. Put more simply, it remembers your shape, hence the name “memory foam.”
As a side note, it makes a lot of sense that Sealy made a memory foam bed-in-a-box mattress since the parent company for Sealy, TSI International Group, also owns TempurPedic, which is the brand that popularized memory foam.
People who are concerned about sleeping on toxic materials will be relieved to know that the Cocoon mattress is CertiPUR-US certified. CertiPUR-US is a nonprofit organization that conducts rigorous safety inspections. What you need to know is that CertiPUR-US essentially says that the bed is safe to keep in your home and sleep on, for both adults and children.
More About The Chill Cooling Cover
The mattress cover is infused with Sealy’s proprietary Phase Change Material (PCM) that absorbs and disperses body heat. In fact, this cover makes the Cocoon Chill mattress cool to the touch (much like its name suggests!). Although many mattress companies claim to use cooling technologies that will prevent the bed from sleeping warm, we haven’t found them to always be effective. The Phase Change Material on Cocoon Chill however, helps provide a fairly cool sleeping surface.
While the Cocoon Chill mattress cover is technically removable, it is not washable. So if you are enjoying a nightcap in bed and end up spilling your beverage, we recommend you spot clean the spill. Instead of rubbing vigorously at the stain, you should gently dab at it with a cloth that has been dampened with water and a little mild detergent. Gently scrub the spill until the spot has cleared, and let the mattress air dry.
On the other hand, if you think there is a good chance you will be making a mess on your new mattress (because, say, you often enjoy eating breakfast in bed), you may want to look into a mattress protector. A mattress protector will help prevent stains from permeating the mattress. Sealy says you can use a mattress protector with Cocoon Chill, but we think having a cover on top of the bed may prevent it from feeling as cool-to-the-touch. It also may prevent the mattress from cooling you down as effectively during the night.
If you are concerned about the Cocoon bed feeling like new for many, many years, we recommend rotating the bed 180° periodically. Most mattress manufacturers recommend doing this every six months or so to help prevent any lasting indentations in the bed. However, this mattress is not flippable.
Cocoon Is Available In Two Firmness Profiles
Cocoon mattresses have a typical memory foam feel, so they will mold to your body’s shape and sleeping position. However, this bed feels denser than most memory foam beds. That means you aren’t going to sink into the bed as deeply as you would a traditional memory foam mattress. Cocoon actually feels like a budget version of a TempurPedic mattress—and that makes sense given that Sealy and TempurPedic are sister companies.
Unlike most memory foam beds (which can tend to retain heat), the cooling compound infused in the Cocoon Chill cover allows this bed to sleep comfortably cool. We’ve actually joked that the cover is so cold that it almost feels wet—and that feeling didn’t dissipate even after months of use.
Sealy offers Cocoon Chill and Classic in two firmness options. The two options feel fairly similar, but Sealy’s most popular option is the Cocoon Soft, which is less dense and allows you to sink into the bed a bit more while sleeping. The difference in firmness is subtle, but the Soft model is every so slightly softer than the Firm option. As you can see in the graphic above, we’re of the mindset that both models are closer to a medium-firm.
If you aren’t familiar with memory foam, here’s a quick overview: it tends to be fantastic for pressure relief, but also is slower to respond to pressure. In fact, memory foam will feel a little firmer when you first lay down, but softens as heat and pressure are applied, meaning you will slowly sink into the material. When you go to switch positions, because the bed remembers its shape, there is resistance when you go to roll over—really common with all memory foam beds.
So if you shift positions while sleeping, there may be a slight indentation where you were before. But, at no point should you feel trapped in a Cocoon bed. Interestingly enough, we think the memory foam could be a double-edged sword for combination sleepers. If you want to be able to freely rotate positions, you might not love it because of the resistance. However, you might also really appreciate the memory foam because it creates a little nook or indentation that nearly perfectly fits your body. As such, you might not feel as inclined to want to switch positions. It’s almost analogous to a weighted blanket or cuddling—the memory foam can make you feel secure.
Our Thoughts On Sleeping Positions
Cocoon beds are made with a dense memory foam that provides enough support for back and stomach sleepers. Back and stomach sleepers typically are attracted to firmer mattresses, so their spine will stay aligned during the night.
As we covered in the firmness section, Cocoon is indeed a firmer mattress, regardless of whether you get the Soft or Firm model. We think stomach/back sleepers will really like this mattress.
While we think some strict side sleepers may be comfortable on this bed, we don’t think it provides enough pressure relief to make it a good bed for all side sleepers. If you are a heavier individual, you might be fine, but it isn’t a great bed for petite side sleepers.
This is a good time to introduce the fact that softness and firmness are moving targets and change person-to-person. There’s a chance that you think the Soft model is perfectly pressure relieving enough, but there’s also the chance that you think the opposite.
As for combination sleepers, we do think Cocoon will be a nice mattress, as long as you’re fine with that dense memory foam feel and you don’t 100% favor your side.
Is It Possible For Heavy People To Sleep On This Bed?
Cocoon beds are supportive enough to work for all body types, including heavier individuals, although we’d still encourage you to first look into a hybrid or spring mattress if you’re in the 250 – 300 lb range, or heavier. The memory foam is dense enough that heavy sleepers should find it to be durable and supportive for a variety of sleeping positions, but again, it might not be your favorite bed long-term, given that it’s still made entirely of foam.
Will Couples Like The Sealy Cocoon Mattress?
If you like to share a bed with your better half, we think Cocoon beds are a good choice, so long as you agree on the aforementioned items such as firmness and feel. The cooling properties of the cover help make sure that even while sleeping next to someone who is exuding body heat, you will be able to sleep cool.
Furthermore, Cocoon has a thick layer of memory foam on top. Memory foam is known for isolating motion well, which is helpful if your partner tends to toss and turn at night. Motion isolation means that the bed does a good job of keeping movement from traveling onto your side of the bed.
This bed also has good edge support, which means that if you find yourself on the edge of the bed, you won’t feel as though you are about to fall off. This is very helpful if you are in a relationship, and not planning to buy a king size bed.
Cocoon by Sealy Review: Verdict
The Cocoon Chill mattress is an affordable, cool mattress that is great for people who sleep hot or live in a very hot climate. It has a dense memory foam feel. Even though it is a memory foam mattress, it does sleep cool. Cocoon Chill comes in two firmness options, but there is only a slight difference between the Soft and Firm versions.
We were sent the Cocoon Chill mattress by Sealy, however, they did not pay us to say positive or negative things about this bed. We review products independently.
No, Cocoon Chill is only sold directly from Sealy, and is not available in any retail stores. Since you can’t try it out in a brick and mortar shop, Sealy offers a 100-night risk free trial. If you decide it’s not comfortable or just not the mattress for you in that time, you can return the bed and get a full refund. We have seen other brands such as Tuft & Needle, Casper, and Purple sell their beds at retail stores, but so far Cocoon Chill hasn’t made the jump.
After unboxing a new Cocoon Chill mattress, there may be a slight smell. It’s called “off-gassing,” and is caused by the cells in the foam opening. It may last a few days, but Sealy says it will typically disappear after the first week that your mattress has been compressed. We’ve unboxed a lot of beds and found that to be true in most cases.
Sealy does not have a minimum break in period, but the company does recommend you sleep on your new mattress for at least 30 nights before requesting a return. This is because it can take some time to get used to a new bed. Sealy says if you are not happy with your new bed, you can return it exchange it risk-free during the first 100 nights.
In addition to the Chill and Classic mattresses, they sell a mattress foundation and the Sealy Chill Pillow. They also sometimes bundle in sheets, but it doesn’t look like they sell those as a separate product on their website. That’s just Sealy Cocoon. If you could Sealy and TempurPedic as separate brands, there are dozens of other products that you can buy, including mattress toppers, adjustable bed frames, bedding, slippers, and so on.
There are 2 firmness options to choose from, but both are around a “medium-firm.”
This is a memory foam mattress with a special cooling cover. It’s actually cool-to-the-touch.
No. This is a 10″ thick foam mattress.
No. Cocoon is a really affordable mattress that sells for (well) under $1,000.
It has a dense/firm memory foam feel.
It should work for side sleepers, though we like Cocoon more for back and stomach sleepers.
