Very poor quality control. Ordered a pair, but was only able to assemble one because the screw holes in the second seat were misaligned. Also, many of the requisite washers were missing, and while the instructions clearly specified 4 flat washers and 4 spring washers for assembly the smaller washers in the kit were definitely not spring washers. I called the company and they sent over a new seat, but not only was it also misaligned, it was damaged during shipment and the washers were also missing. The one intact stool I have is very nice, it's comfortable and sturdy; but given the very poor quality control I can't recommend this product.

(I'll also note, there's no floor protection on the feet; if you're placing these over hard surface flooring you'll want to get some felt pads or something.)
