Comfortable as long as you are sitting straight or leaning back. Not comfortable when used as a work chair and sitting forward to perform desk operations. Constantly sliding forward thus constantly having to scoot back. Also I lean on the left arm rest and the padding is already flat on that side thus not very good padding. Purchased 3 months ago to use at my home office work desk. I personally recommend the Hyken Technical Mesh Task chair which I purchased from Staples 6 months ago that I use at my official office desk. The Hyken is a little more expensive but I believe it's worth it for it's comfort stability.
