This futon sleep sofa is beautiful, comfortable and very easy to assemble. Just attach legs. There was one problem. There are 2 zippers on the bottom. One held the 2 pillows and the other had the legs in a box. 
That box being heavy ripped through the thin black lining. I fixed it with reinforced duct tape so that it didn’t hang down. In the future it might be a good idea to pack the legs separately and not inside the bottom of the sofa.
