I am absolutely head over heels with this mattress!! I've had back problems for most of my life and the mattress I had prior let my entire body sink in- not offering any lumbar support. After sleeping on this mattress I wake up with so much less pain than I's grown accustomed to. The pinching soreness in my back that I always awoke with and sometimes even felt was exacerbated just by lying in bed is a thing of the past!! My partner also loves this bed and has said they've experienced increased energy and back mobility thanks to its support!
