Review: Love this mattress! I sleep hot and this does a great job of dissipating heat. It feels firm but still plush and as someone who sleeps in several positions, this mattress is incredibly comfortable in any position. The cover is quilted and I don’t see any need for a mattress pad. I’ve slept on several foam mattresses (from most online name brands) and this is my favorite so far.
Review: Feels really comfortable, came packaged and sealed perfectly. It expanded in just a few hours did not take 24 hours long maybe 8 hours or less and it was fully expanded. Had a great nights rest too. Definitely worth the money it’s a great deal. Other reviews almost made me hesitate to get this one but I really like it, no complaints. It is a bit on the firmer side but has softness to it in the foam, I suggest get it if you like a firmer bed. I usto have back pain from my other mattress it was too soft and did not support like this one so this one working great worth the money and it is a sealy made in USA can’t go wrong

*by B***D on 7 April 2021*

I ordered the cocoon by sealy bed through the direct website and it was going to take a month to deliver. This bed is cheaper, higher in size (12 inch vs 10 inch) and just as soft, if not softer. It''s soft enough to be comfortable and firm enough to support your back (I'm 5'11", 180 lbs). Plus, the 2 day shipping is unreal. 10/10 recommend this mattress to anyone who wants a quality memory foam.
