So far, it's quite comfortable. I got used to the change in a matter of days. My only minor negative is how tall the mattress is (14") and that it really sinks down when I sit on the edge. I found it necessary to place a footstool next to my bed to put socks & shoes on. Otherwise I slide off the bed. However, edge support while lying down is excellent, which is important because I sleep on only one side of the bed. Overall I recommend this mattress!
