CategoryCriteriaCocoon Classic RatingCocoon Chill RatingWhat Cocoon Users Say
Customer SatisfactionBased on data collection, this is an overall customer sentiment regarding Cocoon mattresses.64% 64%Both Cocoon models together earned a below-average customer satisfaction rating compared to other memory foam mattresses.
Durability The average mattress has a lifespan of seven years, and memory foam mattresses tend to be less durable than other models due to their soft sleep surface and relatively weak edge support.FairFairDurability appears to be average for both Cocoon mattress models, but Cocoon by Sealy launched in March 2016 and the overall lifespan for these mattresses has not been fully assessed.
Motion IsolationMemory foam mattresses are designed to minimize and isolate motion, resulting in fewer nighttime disruptions than innerspring and latex mattresses.Very GoodVery GoodAccording to owners, the Cocoon Classic and Cocoon Chill absorb and isolate motion transfer to a significant extent.
Sex Some couples report that foam mattresses are less than ideal for sex, mostly due to the unresponsive sleep surface that can create feelings of ‘fighting’ against the mattress.FairFairOwners with ‘Firm’ Cocoon mattresses say they are somewhat responsive and bouncy, but the ‘Soft’ mattresses are not responsive enough for most couples.
ConformingMost memory foam mattresses closely conform to sleeper’s bodies, which improves spinal alignment and relieves pressure points.Very GoodVery GoodOwners report that Cocoon mattresses conform very closely and relieve a fair amount of pressure; two available firmness ratings accommodate sleepers with different contouring preferences.
Temperature NeutralityFoam mattresses tend to retain more body heat and ‘sleep hotter’ than innerspring or latex mattresses.FairGoodThe Cocoon Classic sleeps fairly hot, but the Cocoon Chill sleeps somewhat cooler.
Off-gassingSome mattresses produce unpleasant odors known as off-gassing when they are removed from their packaging, and these smells may linger for several days.FairFairLike most memory foam models, Cocoon mattresses produce some off-gassing odors when unpackaged — but the smells will usually dissipate within one or two days.
Edge SupportFoam mattresses generally have minimal edge support compared to innerspring models, and sinkage may occur where people get on to and off of the bed.PoorPoorCocoon by Sealy mattresses offer little to no edge support, and premature sinkage has been reported along the edges where people tend to sit.
NoiseFoam beds are generally much quieter than innersprings and hybrids, due in large part to the lack of potentially creaky metal components.ExcellentExcellentThe Cocoon Classic and Cocoon Chill are virtually silent when bearing weight.
Ease of Moving and RotatingFoam beds tend to be lighter than innersprings, but they need to be regularly rotated in order to preserve the conforming sleep surface.Very GoodVery GoodCocoon mattresses are light even by memory foam standards, making them easier to move and rotate as recommended.

Trial Period and Guarantee: Sealy offers a 100-night sleep trial for all Cocoon mattresses.

  1. There is no required break-in period, and Sealy will allow customers to return their Cocoon mattress at any point during the 100-night trial.
  2. Customers who choose to return their mattress will receive a full product refund. Sealy will also arrange for the mattress to be picked up and removed at no expense to the customer.

  4. Sealy does not restock any used mattresses. Customers who wish to return their mattress may choose to have their mattress donated to charity, recycled, or disposed of at a garbage collection center. Once the mattress has been received by Sealy personnel, the owner will receive a refund within one to two business days.
  5. Customers will not be responsible for repackaging the mattress, and do not need to keep the original boxes.

  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.
