Bought this futon for my study room so there is more sitting space and also a place for guest to sleep over at. The mattress material similar to what others have suggested is of great quality. The dimensions of the futon is also decent and can be placed in a bedroom as a second bed if desired. 
Installation took a bit longer than expected and requires 2 people to get it done. I havn't used it much yet so can't comment on the long term durability yet. Overall a good product for its price.
