Covers the whole width of a queen size bed. (60 x 31 inches). 7 inches tall. Comes with cover and I’ve been using a fitted sheet to cover that while in storage. In almost new condition as used only under mattress for a few months. Paid almost $200 brand new. It's very supportive and so helpful if you have acid reflux or gerd. Can be used on top of mattress or under. This is from a non-smoking, no pets, and no bed bugs household. I live in the Chinatown area and you must pick up. I don’t have the means to deliver, but I can assist you in loading it (if you need it).
