Construction

The Cocoon by Sealy Chill Hybrid contains a memory foam layer and coil core. At 12 inches high, it provides comfort, support and cooling technology. You can even upgrade to an extra shot of cool with Extra Chill Hybrid. Read the following sections for details about construction.

Cooling Cover

The Cocoon Chill hybrid keeps you cool as soon as you lie down. It starts off with a cool-to-the-touch cover made of Phase Change Material. The cover absorbs and sends away heat at the same time, keeping the mattress surface at a comfortable temperature.

Perfect Fit Memory Foam for Comfort

The Cocoon Chill Hybrid provides both comfort and support. If there is a gap between your body and the mattress, it creates pressure and poor alignment in your spine. The Perfect Fit memory foam layer contours to the unique shape of your body, providing pressure relief to your spine and joints. Your body will feel cradled and your spine will stay aligned.

Extra Chill Hybrid Upgrade

Advanced cooling is available with an Extra Chill upgrade. With the upgrade, the memory foam layer is infused with cooling Phase Change Material. Advanced cooling yarns are woven into the mattress cover.

Fabric-Encased Coil Layer for Support

The next layer features fabric-encased coils that provide targeted support. Using Active Support Technology, the coils support your body shape and sleep position. For couples, the individually wrapped coils prevent motion transfer and squeaking when you move or get out of bed. You’ll also enjoy additional temperature control from the breathable Bolsa coils.

Reinforced Coil Layer for Edge Support

The reinforced steel perimeter gives the Cocoon Chill Hybrid sturdy edge support. The result is uniform firmness from edge to edge, which makes the surface seem bigger. The edge support also helps prevent sagging along the sides, which means that you’ll have an easier time getting out of bed.

Medium Feel

With a medium feel, the Cocoon Chill Hybrid provides support without feeling too firm. The responsive foam and coil layers combine to create a medium firmness level with a just a little bounce. On a firmness scale of 1 to 10, with 1 being softest and 10 being firmest, the medium feel firmness is rated 6.

Sizes to Fit Your Sleep Preferences

Part of shopping for the best hybrid mattress for your home is finding the right size. The Cocoon Chill Hybrid is available in a full range of sizes:

  • Twin
  • Twin XL
  • Full
  • Queen
  • King
  • California King

Cocoon by Sealy Chill Hybrid Review: Pros and Any Limitations

After our research and review, we believe that the Cocoon by Sealy Chill Hybrid has the following benefits and minor limitations:

Balance of Comfort and Support

You’ll love the balance of comfort and support in the Cocoon Chill Hybrid. You’ll feel cushioned and cradled without that sinking feeling. The Perfect Fit memory foam contours to the shape of your body while the coil layer provides targeted support. 

Cooling Technology to Keep You Comfortable

With its cool sleep surface and breathable coil layer, the Cocoon Chill Hybrid will help you drift off to sleep in comfort. The cool-to-the-touch cover features Phase Change fabric that draws heat away from your body. The breathable Bolsa coils help prevent the mattress from overheating. Your body heat will dissipate as you sleep so you won’t wake up hot and sweaty.

If you really like to chill, you can upgrade to Extra Chill Hybrid. In addition to the already cool-to-the-touch mattress cover, the memory foam layer gets a cooling infusion of Phase Change Material. You’ll feel cool and comfy for a restful sleep.

Edge Support Helps Prevent Sagging

With the Cocoon Chill Hybrid, you can stretch out and enjoy consistent support from one edge of the mattress to the other. Reinforced steel support prevents sagging, especially around the perimeter. The edge-to-edge support even makes the mattress seem bigger. And you’ll notice how much easier it is to get out of bed when the edges aren’t sagging.

Motion Isolation Lets Couples Sleep Undisturbed

If you share a bed with a spouse or partner, you’ll appreciate the motion isolation feature of the Cocoon Chill Hybrid. It’s tough getting out of bed knowing that you’ll wake up your partner. Thanks to the fabric-encased coils, you won’t disturb your partner if you have a restless night or have to get up earlier than they do. Less motion transfer means you can both sleep easier.

Mattress-In-a-Box Convenient Delivery

Your Cocoon Chill Hybrid will be delivered to your door in a box. Unlike buying a mattress in a furniture store, you don’t have to deal with transporting it home. There’s no delivery team to meet, no appointment that forces you to rearrange your day. Before shipping the mattress, Sealy compresses it in a plastic sleeve and rolls it up to fit in a box.

Although the box is designed to be carried by one person, it can weigh more than 90 pounds, depending on the mattress size. To be on the safe side, ask someone to help you carry the box to your bedroom.

Waiting for Mattress “Off-Gassing” and Decompression

You’ve unboxed your Cocoon Chill Hybrid and can’t wait to try it out. But before you can sleep on your new mattress, you’ll have to wait for it to decompress and get rid of an unpleasant odor. Decompression takes at least a few hours. That “new mattress” smell is caused by the foam breaking open and will go away after a few days to a week.

100-Night Trial

Even top hybrid mattresses need a breaking-in period. Sealy knows that it takes at least 30 nights to get used to a new mattress, especially if your old mattress was soft or sagging. That’s why the Cocoon Chill Hybrid comes with a risk-free 100-night trial that begins on the delivery date. That gives you more than three months to relax, rest and sleep on it. If the Cocoon Chill Hybrid is just not right for you, contact the company within 100 days of delivery. If they can’t resolve the issue another way, you can return the mattress for a full refund.

10-Year Warranty

A new mattress is a major purchase, so it’s important to have peace of mind about the decision. Sealy provides a 10-year limited warranty for its Cocoon Chill Hybrid. The warranty covers manufacturer-caused defects that occur despite normal use and care of the mattress. Examples of covered defects include

  • Impressions deeper than 1 inch
  • Physical defects such as torn mattress cover

Sealy will replace a mattress that is covered by the warranty for free except for shipping charges. It’s a good idea to read the latest coverage details since warranty terms can change.

Monthly Payment Option

Have you decided that the Cocoon Chill Hybrid is right for you but aren’t sure about paying upfront? You may be able to finance your purchase by applying for a Sealy credit card. Details are available on the Cocoon website.

Concluding Thoughts on the Cocoon by Sealy Chill Hybrid

The Cocoon by Sealy Chill Hybrid has foam and coil layers along with a cool-to-the-touch cover. The Perfect Fit memory foam contours to the shape of your body and provides pressure relief. The fabric-encased coils provide targeted support and help keep your spine properly aligned. Couples will also appreciate the motion control provided by the Bolsa coil core.

The cover contains cooling Phase Change Material. With the Extra Chill Hybrid, you get a Phase Change Material-infused memory foam layer and a cover woven with advanced cooling yarns.

Edge support is another top feature of the Cocoon Chill Hybrid. The steel reinforced perimeter ensures consistent and long-lasting support throughout the medium-feel mattress surface.

Sealy ships the Cocoon Chill Hybrid to your door in a box. You’ll love the convenience of direct shipping to your door. However, you’ll have to wait at least a few hours for the mattress to decompress and a few days for the odor to dissipate.

Sealy backs its Cocoon Chill Hybrid with a 100-night trial and a 10-year limited warranty. You can try the mattress for 100 nights after it is delivered in a box to your door. If you decide not to keep the mattress, you can return it for a refund before day 100. The warranty covers manufacturer defects such as tears in the cover or impressions deeper than 1 inch.

After our research and review, our concluding opinion is that the Cocoon by Sealy Chill Hybrid is a quality product of value.
