Query: Ahhhhh!

Very comfortable! Not too soft, not too firm, and helps keep us cooler in bed. Our memory foam mattress has decided to remember our shapes, and now has permanent impressions where we each lie, and the mattress traps heat. My wife has hot flashes, and was looking for something to help, so she ordered this. It does help, and is comfortable. Now if we could just find a good mattress!
