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 absolutely love my chair. I wish I had purchased one sooner. This is for my home office. It was drastically reduced plus I had coupons so that put it in my budget. I have sciatica and this is working wonders for it. I love Staples shopping. I always get good bargains and their free delivery was ever so timely. I had the chair in about 2 days.
