I'm going on 1 year with this chair. The chair is comfortable and does what I expect of it. HOWEVER. As of about 1 month ago, as expected, It started having trouble with the height adjustment creeping down/not staying in place. AND the mounting mechanism under the chair has started loosening up (not the mounting bolts) and started creaking. It's better than the last 4 chairs I bought, not from Wayfair. I honestly believe that who ever is building the mounting mechanisms and the raise and lower cylinders, which, by the way, all seem to look alike, REALLY NEEDS to improve their quality and a good redesign.
