This is the third set that I buy. It was in replacement of the original set bought in 2017 that was beginning to tear. I had bought a second set in 2021 which is still holding nicely. This time, the assembly took over 4 hours: the holes were not lined up and it took a lot of manipulation to get the frame together and add the back. The seat (no holes) was easy to add since you had to drill the screws into the wood. It all looked good until I picked up the chair by the seat and ended up with the screws on the floor and the seat immediately separated from the frame in my hands. A record-breaking fail. I'd return the whole darn thing, but I tossed the box and can't stand dismantling the chairs. I wish I could get a refund and toss the chairs in the trash.
