Important features - adjustable height of arms lowers them out of the way for typing better seat height for a tall person than most chairs back recliner lock provides excellent support when sitting upright. Includes a vertically adjustable lumbar support pad. Easy to assemble. Does not have an adjustable seat tilt which would have been a nice feature but that's generally found in a more expensive chair. Excellent balance of features versus price.
I like that this chair is very adjustable BUT the seat cushion is terrible. It compresses after a couple of weeks and you slide forward. Then there is a bump in the back of the seat cushion and it hurts your tailbone to sit in the chair for too long. I have had to sit on a pillow.
I love my chair! Assembly was easy and fast. The wheels are quiet rollers and I am enjoying the arm rests position changes and back tilt option. I love the fact that it meets California's standards concerning cancer causing materials. As far as I am concern I took a chance ordering this item without the benefit of having an in-store experience and I consider myself a winner!
