When I bought box spring, for some reason I thought it would just expand to full size when I took it out of box. (Duh) Not so, you have to put it together,  that being said it was pretty easy to do. The only issue I had was the bag of nuts, bolts and screws had opened up while in transit, so they were everywhere. Use a drill for screws not a screw driver like instructions say. Also the cover is a bit hard getting on by yourself,  would definitely be easier with 2 people or a big enough space to lay it down on.
