Quick Overview

Cocoon by Sealy offers two different mattress models.  Both the Cocoon Classic and Cocoon Chill are constructed with a comfort layer of memory foam and a support layer of polyfoam, and are available in two firmness options.  The difference between the two models is the cover.  The Classic’s cover is constructed with a blend of polyester and cotton, while the Chill is equipped with a polyester-cotton stretch-knit cover containing phase-change material (PCM) to be cool to the touch.

Our review of the Cocoon mattresses found that motion was contained quite well when a sleeper was moving about the mattress.  We also found the phase change material to be cool to the touch mitigating the normal heat trapping found in most foam mattresses.

While sleep preference differs from person to person, we would recommend heavier sleepers going with the ‘firm’ model for support purposes while lighter sleepers go with the ‘soft’ option.

Pros
  • Two firmness options available
  • Excellent motion isolation
  • Premium cooling Phase Change Material available in Chill model

Sleep Rating

Durability
Fair

Durability appears to be average for the Cocoon Classic, but the brand was launched in March 2016 and the overall lifespan for these mattresses has not been fully assessed.

Motion Isolation
Very Good

According to owners, the Cocoon Classic absorbs and isolates motion transfer to a significant extent.

Conforming
Very Good

Owners report that Cocoon Classic mattresses conform very closely and relieve a fair amount of pressure; two available firmness ratings accommodate sleepers with different contouring preferences.

Sex
Fair

Owners with ‘Firm’ Cocoon Classic mattresses say they are somewhat responsive and bouncy, but the ‘Soft’ mattresses are not responsive enough for most couples.

Temperature Neutrality
Fair

The Cocoon Classic sleeps fairly hot, according to owners.

Off-gassing
Fair

Like most memory foam models, Cocoon Classic mattresses produce some off-gassing odors when unpackaged — but the smells will usually dissipate within one or two days.

Edge Support
Poor

Cocoon Classic mattresses offer little to no edge support, and premature sinkage has been reported along the edges where people tend to sit.

Noise
Excellent

The Cocoon Classic is virtually silent when bearing weight.

As you can see, the Cocoon is a nice choice for side sleepers of all weight categories based on the two firmness options, and performs well for those who sleep on their back. We are weary of recommending the soft option of the Cocoon to larger shoppers, since likely will lack the necessary support, but the firm option of the mattress should be great.  While the Phase Change Material is cool to the touch, if the mattress is rightly covered with a protector and fitted sheet, you won’t be able to take full advantage of the ‘cool to the touch’ feel

Our testing process found the Cocoon should also be great for you if…

  • You’re looking for an affordable memory foam mattress.
  • You love the feel of memory foam – sleeping more “in” than “on” a bed.
  • You tend to sleep hot and want to take advantage of phase change material
  • You sleep with a partner and want to limit the movement you feel on the bed.

  Warranty: Sealy offers a 10-year limited warranty for all Cocoon mattresses.

  1. Warranty coverage will begin on the original date of purchase.
  2. Sealy will, at their sole discretion, choose to repair or replace mattresses with defects that are ‘due to faulty workmanship or materials’.
  3. A full product refund will be issued for owners of mattresses that have been deemed defective, but the owner will be responsible for all shipping and transportation charges. These costs will never exceed ‘Cocoon by Sealy’s then standard freight charges’.
  4. Cocoon mattresses are designed for support on ‘a firm, solid-surface foundation or adjustable bed base that is structurally capable of supporting the weight’. The warranty will be voided if the owner uses ‘inappropriate foundations, box springs, adjustable bed bases, or bed frames’ with the Cocoon mattress. If a warranty claim is filed, Sealy may request the owner for proof of proper foundational support.
  5. Owners may elect to exchange their defective mattress for a more expensive model. In these cases, the owner will pay the price difference between the original mattress and the upgrade model.
  6. The Cocoon by Sealy warranty will cover the following defects:
    • Visible indentations in the mattress surface that measure one inch (1″) or deeper that are not caused by misuse or improper foundational support.
    • Tears in the mattress cover and other product flaws that occur despite proper use.
  7. The warranty will not cover the following:
    • Visible indentations that do not measure one inch (1″) or deeper; this is considered normal wear and tear.
    • Normal increases in the softness of mattress materials that do not affect its pressure-relieving abilities.
    • Repair or replacement requests that occur due to changes in the owner’s comfort preferences.
    • Burns, cuts, tears, stains, and other types of damage that are the direct result of product misuse or improper foundational support.
  8. This warranty is exclusively offered to original purchasers who buy their Cocoon mattress directly from Sealy or an authorized retailer. Warranty coverage will not extend to anyone who buys or acquires their mattress from the original owner or a non-authorized retailer.

How Does Cocoon Compare to Other Beds?

As any consumer does with a product they’re considering, our mattress assessments naturally involve comparing them with other similar products. Be it composition, firmness, or price, we think it’s important to see how the Cocoon stacks up to other beds.

The Cocoon is priced very affordably relative to other mattresses of its quality in the foam category. The use of the phase change material on the cover of the Chill model gives the mattress a small leg up to other brands in the same category.
