This item replaced my HM Aeron chair. This chair has all the same features at 1/3 the weight & 1/3 the price. I sit in front of a monitor most of the day. This chair provides the support to keep me focused on work. The lumbar support is a big improvement from other chairs. It's adjustable and stable. The headrest is a nice toch too. Perfect for removing the glasses and taking a small break. This is the best chair I have purchased in 2 decades.
I'm 6ft 2 and 235 lbs. The back support is not good at all. It doesn't keep it straight and leaning back on the chair makes you lean back like you're pondering life looking at the stars.. and that's with the forward lock on. Leaving it off makes you lean back further. The back rest doesn't stay put and always pushes itself down. Head rest is great if the back didn't lean back so much. Very disappointment and wouldn't recommend.
The chair is what I was hoping for but there are a few issues I think you should know about. When you lean back the lumbar support snaps down so for long sessions you're better off keeping it in its lowest position as it will eventually fall back to that level when you lean back anyways. The chair also tends to rock side to side a bit in a way that does not feel natural. Very comfortable otherwise but I would like to see these issues fixed. For reference I'm a 5'11" male 175 pounds with a 32 inch waist.
Cant beat it for the price. Great lumbar support which was what I was lacking for the past year WFH. Very similar to a much more expensive chair I have in my office.
