I brought this mattress after a friend had recommended it. I wasn’t holding my breath as I’ve had years of being in pain whilst in bed. I am 38 years old and have 3 slipped disc in my back, top, middle and bottom along with osteoarthritis. I get stuck laying on my back and I’d be in constant pain. I purchased the medium soft mattress and it’s made a massive difference. I don’t wake up in pain and I am have a very restful nights sleep. Really wished I changed my mattress 6 years ago when I first started having back issues.
