Got this for my daughter's dorm bed. (It was hard to find a gel topper in XL twin.) When I first opened it up, it didn't seem to have the memory foam characteristics and I was very disappointed, but after a few hours, it was just as I hoped it would be - cool gel infused memory foam. My daughter is very pleased with the added comfort of this topper on a hard dorm mattress. If you get this topper, wait a few hours after opening it up, and you'll be very pleased.
