A few years ago, we bought this because my daughter was uncomfortable in her twin bed. She is 5'7" and weighs all of 120 pounds, but some standard twin mattresses are crummy. My husband and I had just gotten another memory foam mattress from and were very satisfied. Fast forward several years and we have a kid who has sworn off anything except memory foam mattresses. More recently, I have a 25 year old nephew who lives in a group home. They are provided with twin beds, but those beds are not built for comfort - at all. I had my nephew try my daughter's mattress and he really liked it. He is 6'1" and weighs about 230 pounds. He was so happy when this mattress arrived, and has found it to be extremely comfortable. His sleep is better and more restful. There is plenty of "give" in this 8" mattress, but I didn't want to risk having him bottom out. That does not seem to be an issue at all. This is a great value, and the quality is top notch. If I need to buy another twin mattress, this will be my first (and probably only) stop.
