My husband and I have always had sleep problems. Him mostly because he is a vet who served in 2005 and sustained a few back injuries during IED explosions. Besides bad dreams, our past bed didn't allow him to get comfortable not allwing him to even try to sleep. I've had major hip problems (maybe becuase I didn't have any) since I had our little girl. My hips shifted so much that any pressure to them at night cause quite a bit of pain. Not any more. This memory fowm has been great for usboth. We both havent' sleep this good.....well.....ever. After reading other reviews, we thought the the medium firmness might be our best bet, but I think even the softest one might have worked. He is about 280 and I'm about 250 lbs, and feel that it is just right if not a little too form for us. Keep in mind the bed feeds off of your body heat, so it tends to get warm, but I think it's great! Perfect for us. And we got the king size, and don't see any of the problems that people have seen with the other king memory foam beds. We would recomend this bed to anyone and everyone!
