So far we have had the mattress for almost a week and we like it a lot. I generally prefer a firmer mattress but after lots of research for side sleepers, health and safety, etc. - I decided to get this one - medium firmness. At first it seemed it was too soft, but after actually lying down and sleeping, it feels pretty good and great support for your body. It has made an immediate difference in comparison to our old spring mattress which had us waking up with all sorts of aces and pains. The only slight concern I have - the sides feel kinda “bouncy” and easy to roll off from. The mattress box is very heavy so definitely need two people to carry.
