Our previous futon mattress (cushion style, no coils, no foam, etc) got squashed flat eventually by kids pets and adults using the futon as both couch and bed too often. I liked the idea of a coiled mattress style so opted to try this. 

Size is great, fabric is great, mattress is comfortable. Took a few hours to puff up from the packaging, but to be expected. In the couch position, it is amazingly comfy. In the bed position is it also comfy, although rather bouncy like a waterbed so be warned.

Watch out for: the packaging was really HARD for a single person to wrestle, in my opinion. Bringing it inside, opening the box, and then removing the plastic wrap without harming the mattress with a blade was a trick. Also the plastic tufts on this are annoying. With a cover on, they are thankfully not noticeable. Good purchase!
