my husband has had many back operations and needed a good support for his back, he loves it. i like it, i do not like firm matteress's so i got this in plush. do not let the word plush fool you though, i would say it is medium plush because it conforms to my body. if you are like me and like to feel as if you are sleeping on a cloud i recommend you buy ultra plush. i will get used to it though for my hubby due to the fact that it has a tiny bit of way to it.....i give it only 3 stars because when it was delivered the box had rips in it and the mattress itself had a rip in it like someone used a box cutter on it :( hopefully wayfair will help us figure this out when i give them aa call shortly
