I found that the build quality of the chair was exceptional, although the packaging could be improved to prevent damage to the chair in transit. The seat cushion and backrest are comfortable over long time periods. Unfortunately, the chair didn’t fit my narrow shoulders as I had to flare out my elbows to rest them on the arm rests, so I ended up returning it, but I feel it would be very comfortable for most people. Customer service was very responsive and worked with me to setup the return and it was hassle free. I highly recommend this chair for anyone looking for a quality ergonomic chair with tilt locking, height adjustment, seat depth adjustment, armrest height and forward/backward adjustment at this price.
