Really comfortable. If you like soft, spend a little extra money on the Plush option. I have become a big fan of these memory foam mattresses - this is our fourth one since we started replacing each family member's mattresses. You can't beat the ease of shipping either since they arrive in a very compact package and the mattress expands when you open it. You don't need a box spring as long as the frame you have will support the memory foam, usually with slats.
