I was so excited to begin setting up this mattress because as soon as it was removed from the box it felt and looked as high quality as it is! I let it air out and breathe for a full 48 hours before setting it up in my bed frame. It is thick and plush once expanded with no divots or wrinkles! Memory Foam mattresses are my favorite as they provide full support without the pain of springs. The added gel to this one helps me remain cool and expands around me as I move during my sleep. I highly recommend this twin bed for anyone in the market for a reliable and durable mattress!
