This mattress feels really great on it's back. Totally recommend it for back sleepers. I feel like I'm laying down on a cloud of support. Your partner will not feel you get in and out of bed.

This is NOT a bed for side sleepers. In my first week, I slept on my side and it crushed my arm straining a neck muscle. That neck muscle was strained for a week. I couldn't turn my head or move my arm without feeling pain. I like sleeping on my side because I snore sometimes and it usually helps me sleep better. Not sure I'm going to keep this mattress. With that said, I've had really good sleeps on my back with this mattress.
