I already have a memory foam topper for my bed and love it. My kids mattresses are getting older now and not so comfortable anymore. Decided to buy two KING sizes, cut them in half to make 4 twin sizes and let the four kids share them. The comfort level was okay, but I decided to spoil my kids just a little more and put the two halves together to make a 3 inch topper. Definitely VERY comfy. I have already ordered two more king size to do the other 2 beds. I was a little nervous about trying to cut the foam but it was extremely EASY using an electric kitchen knife. $$$ a bed to extend the life of an old mattress is WAY cheaper than buying a new mattress! And as Goldilocks said, "It's not too hard and not too soft. It's JUST RIGHT."
