Really good chair my only complaint is the head rest. I am on the taller side so the headrest sits too low. You can fix this however by taking it off and removing the two phillips head screws in it then flipping the arm around and reinstalling it. Its a pain to do because the screws are inside the headrest and you have to get an L-shape wrench in there to get them out but its worth the effort. Other than that the chair is fantastic.
Compared this with $1 500 chairs and prefer it to all 15 other chairs we ever had around here and it costs 1/10th the price. Out of 9 chairs two of them had the gas cylinders go bad but Staples go them immediately replaced for free under warranty. The warranty is 7 years.
As a remote worker it's been a challenge to find a supportive and comfortable chair for long hours at work. A colleague recommended this chair to me and I'm so glad I listened to their advice. It's comfortable and supportive and I can comfortably sit all day without back pain. I've noticed a difference in my back issues even when I'm not working and I thought it was my mattress. Highly recommend this chair to anyone looking for a good work or gaming chair!
