Not made to last very long.  Had several break this year.
I have bought about 12 of these over the past few years because they are great size, good amount of cushion and decent wheels.  The quality of the build is not meant to last.  We have had 3 chairs break at the plastic base over the last six months, we have had about 1/3 of these chairs need repair to the arm that raises & lowers it.  We were not exceeding the weight limit, both users were around 220 pounds sitting still when the chair failed. The tabs that hold the arm to raise & lower bend & eventually break off making it not possible to go up & down.  These $80 stools don't last as long as the $50 stools I used to buy 15 years ago.  I'm hoping the manufacturer of these stools will start using better materials or engineering to make a better product.  I really like the rest of its features but durability has me looking for another brand to start buying.  We are lucky to get 1.5 years out of these and recently we have had chairs less than 6 months old fail at the base.  They are used 4-5 days a week for around 8 hours a day.  I now have a pile of parts to constantly repair & rebuild these stools, things just aren't built like they used to be.
