just not the right fit for me... i often wake up with achey back or hips after sleeping on it.  other than that it was as described. expanded to almost the full size. maybe a 1/4 inch shy.  and to be honest i miss the bounce of an old fashion innerspring mattress... so for now it is ok - buti am saving up to go back to an innerspring... the one thing i do like is the little grips on the bottom to keep it from sliding around...
