Slumber Solutions Big Bump 4-inch Memory Foam Mattress Topper, Size Queen

Forget spending the big money to upgrade your mattress. I bought this one for the RV, after having one on my bed at home for the past 4 years. It adds softness, without taking away the firmness of the mattress. We have a "new" memory foam that I hate (I wake up in a "hole") - this pad makes it much more tolerable!
