I needed four mattresses for two bunk beds. I bought two of these, put them on the floor, and slept on one for several nights. I found it extremely comfortable and would recommend for a standard twin bed.
However, once I put them on the bunk beds, I realized my mistake: the pillow top makes it almost impossible to make up the top bunks. They are heavy to lift, and the ridge around the pillow top gets caught on the guard rail. Fortunately, I had also bought two mattresses at a mattress store, and those are much lighter, so I put them on the top bunks. If you are purchasing for a bunk bed, I recommend going to a mattress store and lifting each mattress to make sure it is not going to be too heavy; making up bunk beds is already awkward enough without a heavy mattress.
