I bought this chair in 2020. It started out great but then the foam armrest broke off the first year. Last year it started to slowly dip when seated. This is the worst as you have to constantly raise it back up! I have to sit a specific way to prevent it from dipping which is not good for my back. I have other chairs that are still holding up. Rollers on the wheel are thinner so it will not work as well on thin carpet.
I had gotten this chair at work to help with lower back problems. I liked it so much when I got a new job working from home I bought the same one. So comfortable. Great for sitting all day with a bulging disc.
