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.
So far so good. Back of the chair was sticky probably from plasticizers in the storage bag. Chair is comforfable but can't sit for over 3 - 4 hours. It needs more comfy seat padding
Once I got the lever settings right the chair was great! Very comfortable -- my back was aching really bad and now I have no aches. I am using it without the arms - easier for me to move in and out in the office space I have.
