Unfortunately, had to return this item due to poor design by manufacturers.  Some of the threaded inserts are welded into the legs at the wrong angle, preventing the screws from going in without stripping the threads. Both chairs had exactly the same misalignment on the same assembly points, meaning that these are most likely done by automated manufacturing.  Strongly suspected replacements would just have the same issue.  On the plus side, Wayfair made the return process very easy.  Thanks, Wayfair!
