I bought this mattress to replace a cheap foam futon mattress that had become very thin and uncomfortable. I've only had the new one for a couple of days, so I can't comment on how well it will stand up over time, but it is VERY comfy! I can't feel the bars of the futon frame underneath me when I sit on it or lay on it, and it has a very firm and "springy" feel that is similar to real furniture like a couch or chair. Overall, I'm happy with my purchase. For the price, this is a significant improvement over what we had. The only reason I'm giving this four instead of five stars is because the product description says that it is 10 inches thick, and it's really more like 6.5 inches. That on its own doesn't bother me (comfort is more important than thickness), but I ordered a futon cover to go with it, and specifically got the bigger size intended for futon mattresses that are 10 inches thick or thicker. The cover is a bit large and looks wrinkled and sloppy. If you're ordering a cover to go with this mattress, choose the smaller size.
