What Is Cocoon Chill Made Of?

Cocoon Chill is a 10”mattress constructed with multiple layers of foam. The bed 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.

If you go with the Soft model, you will get a transition layer, which, as you’d expect, helps soften up the mattress. If you get the Firm model, you lose the transition layer so that you feel more of that dense support 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.

People who are concerned about sleeping on toxic materials will be relieved to know that the Cocoon Chill mattress is CertiPUR-US certified. CertiPUR-US is a nonprofit organization that conducts rigorous safety inspections.

Cover, Cleaning, and Care

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 Chill 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 Chill Feel, Firmness, and Responsiveness

Cocoon Chill has a typical memory foam feel, so it will mold to your body 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. Unlike most memory foam beds (which sleep warm), the cooling compound infused in the Cocoon Chill cover allows this bed to sleep comfortably cool.

Sealy offers Cocoon Chill 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 sink into the bed a bit more while sleeping.

We’d say this bed responds slowly to being compressed, which is typical for memory foam mattresses. However, combination sleepers will appreciate that there is not really a deep stuck-in-the-mud feel on Cocoon Chill.

Slower responsiveness, but still easy to rotate positions

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. This is because the Cocoon Chill memory foam is dense enough that you should be sleeping ON it, instead of IN it.

Is Cocoon Chill Good for Back and Stomach Sleepers?

Cocoon Chill is made with a dense memory foam that provides enough support for back and stomach sleepers. Back and stomach sleepers need a supportive mattress, so their spine will stay aligned during the night.

Is Cocoon Chill Good for Side and Combo Sleepers?

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 in general, this is not a bed for side sleepers.

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 favor your side.

Is Cocoon Chill Good for Heavier People?

Cocoon Chill is 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.

Is This A Good Mattress for Couples? — Edge Support and Motion Isolation

If you like to share a bed with your better half, we think Cocoon Chill is a good choice. 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.

Very good at isolating motion

Furthermore, Cocoon Chill 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.

How did the Slumber Yard get this mattress?

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.

Is this mattress built in the United States?

Yes, Sealy designs and assembles all their mattresses in the U.S.! They are all shipped from Sealy’s Belmont, Mississippi facility.

Is the Cocoon Chill available in retail stores?

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.

Will my new mattress smell?

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.

Does Cocoon Chill have a break in period?

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.
