Everything that's advertised! Extremely comfortable and get a great nights rest. Supports you where it should and contours to your body where you need it.
Before this mattress, if I did get a good night's sleep, my body ached terribly. Often forced to rise earlier than necessary to stretch. Just a week on this mattress & my usual aches & pains are melting. I wake well rested & even lounge a bit on weekends, enjoying the absolute comfort of this mattress.
We got the split king flex mattress and adjustable base and we love it! We weren't sure we would use or like the vibration feature on the base but it is so soothing and relaxing that we use it nightly. The mattress is firm but comfortable.
