I've paid a similar price for a memory foam pad alone, so I think this set is a great purchase. I cut open all sides of the plastic wrapper and then let the pad and cover sit out on the floor to expand for a couple days. When I was then able to use it, I loved it immediately! The fluffy pad cover makes it feel as though you are sleeping on a luxury mattress. The cover's elastic straps hold the corners well, and the mesh fabric, with very deep pockets, pulls down easily over my 10–11 in. mattress with the 4-in. topper in place.  My slightly stretchy cotton jersey fitted sheet, with 14-in. deep pockets, fits well also, as one photo shows. I haven't noticed a cooling effect, but I sleep very well on this topper set. Very nice!
