Can honestly say this is a very comfortable matress. From the first night I've woken up without stiffness or aches and pains. I wasn't 100% confident when I ordered due to some of the reviews but I'm very happy I took the risk. One thing I will say, its not double sided and yes you can feel the coils on the side but you can't feel them on the top where you actually sleep. Got it in the sale but would gladly pay the full price for it.
