Cocoon by Sealy Review

Bringing 130 years of expertise with them, mattress pioneer Sealy entered the bed-in-a-box market just four years ago in 2016 with their Cocoon™ by Sealy mattresses. The result of two years of R&D and over 100 different prototypes, these mattresses quickly gained popularity for their uniquely cooling and supportive features—earning 6,000 reviews from satisfied customers with an overwhelmingly positive 4.7/5 average rating.

Aside from esteemed mattress quality, Cocoon™ by Sealy's generous at-home trial period, decade-long warranty, completely American manufacturing process and rigorous laboratory testing have all undoubtedly contributed to becoming one of the top contenders in the bed-in-a-box space in such a short amount of time.

What kinds of mattresses does Cocoon™ by Sealy offer?

Cocoon™ by Sealy makes things simple for customers by only offering one mattress. the Chill Mattress, engineered with their proprietary Phase Change Material (PCM) technology that absorbs your body heat as you sleep, allowing you to sleep as cool as possible.

Inside of the Chill Mattress, you can find two layers: The Comfort Layer on top and a Base Support System underneath. Both are covered by a stretch-knit, breathable, cool-to-the-touch Fabric Cover. The Comfort Layer is meant to cradle you using a high-quality, higher-density foam, whereas the Base Support System controls the firmness of support you experience using a “more robust foam engineered to be highly durable and resilient.”

Customers can customize their Base Support system to be either Extra Firm or Medium-Soft — the two most desired firmness options as discovered by Sealy in their 130 years making mattresses.

To help you choose the right firmness, Cocoon™ by Sealy recommends choosing Extra Firm if you like sleeping on your bed—meaning you prefer your mattress to be “sturdy and more substantial–and Medium-Soft if you like sleeping in your bed—meaning you prefer your mattress to be “cozy and more enveloping.

If you’re still unsure about which firmness is right for you, you can also look to the 5,000+ reviews on Cocoon™ by Sealy's site for more guidance. You can even sort these reviews by keyword, firmness, rating score and recency, making it easy to quickly narrow down the reviews to only those that are helpful to you.

Even easier than picking a mattress from Cocoon™ by Sealy is their mattress setup process. After having your bed shipped and delivered to your house for free, setting it up is as simple as following these four steps:

  1. Unbox: Slide the compressed mattress out of the box.
  2. Set It Down: Place the rolled mattress on a flat, sturdy foundation.
  3. Set It Free: Remove the tape and pull the wrapper apart at the seam.
  4. Let It Settle: Your mattress will reach near-full shape after 1 minute.

You can also take refuge in the fact that, before being sold, all of Cocoon™ by Sealy's mattresses are tested for durability, comfort life, safety/flammability, and even the effects of packaging, shipping, and handling. To give you an idea of what this testing looks like, Cocoon™ by Sealy's “Rollator Surface Fatigue” and “Mattress Durability Impact Test” use 225 lbs of force over and over (simulating 10 years of use) to evaluate how their mattresses stand up to wear and tear.

How compatible are Cocoon™ by Sealy mattresses?

While Cocoon™ by Sealy doesn’t explicitly state that their mattresses work with all bed frames, in their setup instructions, they instruct you to set down your mattress on “any flat, sturdy foundation.” This would suggest that their mattresses will work with most bed frames fitting that description.

Although they also offer their own brand bed frames for those who want to be certain or don’t have an existing bed frame.

Their DreamFit pillows come with 100% cotton covers and offer different comfort and support on each side of the pillow, with the support of foam clusters on one side and the plush comfort and support of polyester fiber on the other side.

Their DreamFit sheets are also 100% cotton, offering a single-ply, authentic 260 thread count. They also come with 360° 1-inch binding and corner straps, meaning that your sheets will stay snug to the mattress and not expose your lower half as you sleep.
