I’ve enjoyed the chair so far and the multiple adjustment options make it nearly a winner. Its one minus is seat comfort. I found it to be harder than anticipated. Fortunately I had a nice seat pad I used on an old chair which is making it much more tolerable.
Since working from home the last several months I've been in a folding chair. This is a huge upgrade and I love it. It's only been a few weeks so not sure about the long term wear. Only complaint is the design of the armrests. They have a dip/ channel in them for your arms which at rest is okay but when typing the edges dig in. I get carpal tunnel so I rely on the armrest to keep my wrist and elbows flush with desk level.
I'm very happy with my purchase. Now am able to work from home in comfort as this chair greatly resembles the one in my office. Although I make it a point to get up at least every half hour I can sit for hours if need be. The chair is fully adjustable save for one thing: the arm rests while vertically adjustable only go down so far which makes it somewhat to type on a keyboard that is at waist level. That is the reason for four stars instead of five. Otherwise very satisfied: the mesh back allows for air circulation and stays cool the seat cushion is quite comfortable and the price is right.
