Extremely pleased with the quality of this futon mattress and platform. Very easy to assemble if the directions are followed. The support straps for the mattress were stapled on backwards but this did not affect the sturdiness. All parts included. The mattress is comfortable for sleeping (2 adults) and seating(3 adults) although pillows are needed for back support for sitting upright. There are two positions for seating, the one in my photo is the most upright and works well when the room is used as a home office. The mattress is long enough for my 6’2” son to be comfortable when visiting. The mattress does have a slight new scent after being set up for weeks, but I use a mattress pad under sheets and this covers the scent. Easy to open, but it does take two people to reset it back upright. Would definitely purchase again.
