This mattress topper totally improved the comfort of our sleeper sofa. However, I'm not so sure that you couldn't do the same thing for less money, since this is just one of those yellow "eggcrate" toppers slipped inside a quilted cotton mattress pad/cover. You could buy an eggcrate topper at a discount store and put a queen mattress pad over the top and it would be the EXACT SAME comfort-wise as this and it might cost less. Only con is that it's too thick to keep on the sleeper sofa when it's folded, and it's quite bulky to store. I was barely able to shove it underneath our regular queen size bed!
