Missing three bolts x 4 and one unit x 8

Can't finish assembly. 

Complicated to put together.

Heavy. Website says delivery crew will carry up stairs up to two flights. The mattress was delivered first then the wooden sofa frame days later. They were both left outside in the open after a quick doorbell ring. Glad I was home. Had to drag up two flights of stairs. The website said they would remove carboard packing. Nope I had to. 

Sofa bed not built so can't comment on form and function.
