I have a disease that cause bone pain in my entire hip bone/cradle/girdle. This mattress allows me to lay on my hips, sides, pelvis, back bone and stomach without pain. I was unable to do any of this for a long time and had to use soft bamboo pillows and lay a very specific way to have any relief; even then needed strong pain meds. Now I barely need anything!!! I sleep better and walk better during the day. So happy to have been guided to the mattress!!
