This is the perfect sofa for small space living.(it can also be used as a bed in a pinch)  When I opened the box it came in, the futon was covered in a slipcover fabric bag to keep the surface clean. (wonderful to retain for a future move)  In the back of the futon is a velcroed compartment that holds the four sturdy legs. The legs screw onto pre-installed posts so set up takes only a few minutes. I am very well pleased with this product and may purchase another one for my art studio.
Update: I have had this sofa for two years now and it is still sturdy and looks very good with regular vacuuming. I'm not in love with the fabric as it picks up hair readily, but an attractive throw over the back helps prevent that from happening. As a guest bed, it's not super comfortable because of the seam in the middle when it is laid flat. I fixed that problem by buying a foam topper to place on top when guests come and it works great.
