So assembling these stools should only take about 15 minutes. But because the screw bolts are too short and the holes are too big (wide) you can’t get the threads to engage. I’m at almost an hour to put just one together and it’s still not done and I’m pretty savvy with these type things. I’ve tried not using the springlock washer to gain an extra thread and that works but then you lose confidence that the screw bolt won’t back itself out over time. Only 3 stars for the aggravation.
