I got this for my son who is autistic and complains about his back.  He's a big guy.  He loves it!  He didn't even make it out of the house to see his friends the next morning because he was too comfortable.  No complaints from him.  I then bought one for my Mom who is on hospice and bedridden.  She said that it was great.  She got a good nights sleep.  Her sleep is intermittent.  I also just purchased one for myself and some new bedding for my son's bed and mine!  Thanks Wayfair!
