Well, setting up the chairs was a major pain. I was so frustrated I could scream. However, If you do the set up steps backwards the chairs can be put together in 6 min. Just remember to reverse the steps. The round plate is the last thing you put on the chair not the first. The legs have a center groove for placement. You may have to rotate the legs in a circle until you get all the holes lined up. The black washer (the big one) needs to be put on the chair base first, then the legs put the white spacers on before tightening down any screws. Tip get the screws in place don't tighten any of them until all the holes match up. Then tighten. I have notified the manufacturer that the steps are done in the wrong order.
