I searched everywhere for sleeper couch like this that wasn't overpriced. This is the perfect couch for our new condo in Hilton head. Warning it is heavy. Translate to sturdy. The mattress is about 4 inches thick I like it but will addA memory foam mattress topper for more comfort for my guests. The quality of the material is great I will Scotchgard it. And I am looking for arm covers just to keep it clean. I would definitely recommend this couch to anyone and Wayfare is an incredible company to work with. When I called customer service to explain the details and the specs because this was a new product on the website they were extremely helpful and contacted the manufacturer to answer my questions. There is no assembly required for this piece
