Well, I bought this in the middle of summer but then went away for 2+ months, and due to upper respiratory infection slept in recliner for another month so I just started sleeping on it a week ago. I am a side sleeper and I already feel pain in my shoulders. I think it's going to force me to be a back sleeper, which will be OK especially since I have an adjustable base... That's my review! I think it's a quality mattress but circumstances in my own world kept me from perhaps trading it for a softer mattress...
