We bought the chair unassembled and my 15 year old granddaughter did the assembly which tells you is is not difficult to put together. There was a small plastic button for the armrest that was not formed correctly so that the armrest would not adjust when installed. I called support and they promised to send out a new piece. I am writing this review prior to receiving the replacement part. The chair came with an attachable headrest we did not install as it seemed unnecessary to us. Others may not agree. The chair is comfortable and quite serviceable. To this point we are pleased with the chair.
I bought this chair for my husband was easy to ensemble and very comfortable staples have an excellent service and the free shipping to my home was the best deal ever. I recommend this product to everybody that is searching for a comfortable and fresh office chair.
I bought one of these chairs a year ago but am sorry that my first chair kept going down and I tried to fix but had no success. I had to discard it and bought a second chair. I would never by insurance on a chair. Ridiculous.
