The Cocoon is available in both a soft and firm option. However, both mattresses fall more to the firm side of the spectrum. The firm mattress is rated an 8 out of 10, with 1 being extremely plush and 10 being very firm. This firm mattress option is ideal for stomach sleepers who need to stay on top of the mattress instead of sinking into it.

Unfortunately, the soft mattress is not very soft. It is more of a medium-firm mattress. It is rated a 5.5 out of 10. Many users, particularly side sleepers who desire a soft mattress, had to return this product or add a mattress topper due to its firm design.

This memory foam mattress offers a basic memory foam design. The firm option features two foam layers, while the soft option boasts three. The Cocoon stands out from comparable memory foam products due to its two cover options: the Classic and the Chill. The Cocoon classic cover is a basic mattress cover made of polyester and cotton.

However, the Cocoon Chill uses a phase change material that absorbs heat, helping you sleep cool all night long. If you sleep warm, this option will provide for many cooler nights but it does come at a significantly higher price tag.

This memory foam mattress is several hundred dollars less than other memory foam products on the market. However, that cost will vary depending on the cover option you choose. Unfortunately, several users had problems with strong off-gassing, which lasted for several days.

Even more, numerous users found this mattress didn’t expand properly, even after a week of being unboxed. This was a common complaint from many users, but these defective mattresses are covered under the product’s warranty.

Available Sizes: Twin, Twin XL, Full, Queen, King, Cal King​

You Might Want to Pick the Cocoon Mattress If:​

  • You prefer a firm mattress: Both the soft and firm options fall on the firmer side of the spectrum. Stomach and back sleepers will find plenty of support and comfort with this product.
  • You sleep with a partner: The Cocoon offers little bounce and excellent motion isolation, so no matter how many times your partner gets up in the nights, you won’t be bothered.
  • You don’t want to pay a fortune: While many memory foam mattresses can cost you thousands of dollars, the Cocoon boasts a budget-friendly price tag.

What to Look for in a Mattress

  • Firmness: Look for a mattress with a level of firmness that is best for your favorite sleeping position. Back sleepers need a medium-firm product that offers plenty of support, yet enough cushion to prevent the mattress from pressing on their spine. Stomach sleepers should consider a firm mattress and side sleepers need a soft mattress that lets them sink into the bed.
  • Construction & Materials: Mattresses vary in their construction and the type of materials used. Look for products made from high-quality materials. Thicker mattresses are generally softer and are ideal for heavier individuals.
  • Temperature Regulation: Some mattresses — particularly memory foam mattresses — trap in body heat causing you to sleep hot. Look for products with cooling properties such as cooling gels or breathable fabrics to help disperse heat and keep air flowing.
  • Motion Isolation: If you sleep with a partner or animals each night, look for a mattress that absorbs movement. Typically, thicker mattresses and those with higher foam densities have stronger motion isolation.
  • Trial Period: Consider products that let you try the mattress for a minimum of 100 nights. If you find you aren’t satisfied with the mattress during that time frame, you can return the mattress free of charge and receive a full refund. Longer trial periods are ideal as new mattresses can take several weeks for your body to properly adjust.
  • Warranty: A standard warranty for a memory foam mattress is 10 years. The best warranties from mattress manufacturers are 20 years or longer.​

Final Verdict
