Only had the chairs for a few days but they seem fine so far.  We have used them several times with no issues.  It took my husband and me 2 hours to assemble 4 chairs (1 hour per chair).  They were not difficult to assemble, just awkward.  Also, the instructions were not clear on which screws to use for each piece.  Had to back out and start over a couple of times.  Discovered the directions were serious when they showed putting the seat back on the seat before attaching to the swivel.   Hope the last we they look good in our setting.
