I slept on this mattress for a week while caring for 60 lb. foster dog who never left my side. There wasn't enough room in the bed for him, me, my husband and our black lab! I was pleasantly surprised at how comfortable this mattress was, and I have a nagging lower back injury. I slept pretty well and the foster dog slept VERY well! I think it is pretty much impossible to get a futon mattress as comfortable as a regular mattress, but this comes close. I would definitely recommend this for someone who wants to use it for regular guess (far better than a pull out couch mattress, too). I imagine it would be a very good choice for a child or young adult, too. It DOES have a peculiar smell after being unpacked - I would recommend it be aired out at least a week before you use it and also, the use of a spray mist freshener for fabrics helped a lot.
