I would not technically consider this "memory foam". It is super light weight and low density. When you press your hand into the cushion, instead of leaving an imprint of your hand, the foam fluffs back up right away. I've purchased a much cheaper 2" memory foam that weighed about twice as much as this one, and it provided much more support and cushion.
One thing people seem to leave out in their review is that this mattress pad has several small holes for "ventilation" throughout the entire body. Beware!
The quality of the foam is cheap, but I must admit it was comfortable. Unfortunately, this comfort only lasted a few months. So with everything considered, this is a very overpriced memory foam pad with a ridiculous original price tag. I do not recommend this pad if you're looking for memory foam!
