It took two of us an hour to assemble it. When we got to the very last steps of putting the back rest on, we realized it was one and a half inches shorter in width than the seat  rest! The screws were never going to make it to the holes, and it wouldI have looked weird to have the seat rest and the back rest two different widths. Then we had to spend another 40 minutes disassembling it to get it to fit in the box to ship it back.
