Unlike some reviewers I found assembling this piece a bit challenging, and I am usually pretty good at it. Part of the problem was that the packaging was damaged in shipping and the product was slightly damaged. But there were also some quality issues: the included screwdriver broke. The tip broke off in a screwhead and I had to drill out the screw. Hint #1 is, if you have a good, comfortable Philips head screwdriver, use it and throw away the included screwdriver before it does any damage. The job will also go faster with a screwdriver with a full-sized handle.
Hint#2: be careful not to install the long hinges (Part C) backwards. If you look very carefully at the instructions you will see that each hinge has a circular bit where the two sections meet, sort of like a kneecap for the hinge. The instructions show the kneecap on the side of the hinge toward the back of the bench. Before driving in any of the screws for the hinges, stop and look where the hinge's kneecap is. If it is on the side of the hinge toward the front of the bench then you have it backwards and the bench will be unable to close. Stop. move the hinge that's on the right to the left side, and the hinge from the left side to the right.The kneecaps should now correctly point to the back.
Hint#3, I found it easier to attach the seat (Part 6) _before_ attaching the seat back (Part 5). It's easier to get the screwdriver in and drive the screws straight.
Hint #4: save yourself the trouble of half-removing a bolt you have fully driven in. When attaching the box back (part 4) to the side pieces (part 1), install just three bolts, the two at the bottom and one of the two at the top. This will leave the bench loose enough that you can fit the seat back (Part 5) in without loosening anything. Install the four bolts that hold in the seat back and then the final (fourth) bolt for part 4. The unit's coloration was a bit lighter than the catalog illustration.
Once you complete the assembly, this is a convenient storage unit to place just outside your entrance.
