This chair is very supportive and extremely comfortable for long work days. The mesh back and seat support keep you cool and comfortable and the headrest is a nice feature. It is the perfect chair for someone who is of a slim to medium body type.
I love this chair. Love it. I had one for about a year and then the lift cylinder gave out and it kept dropping down so I had to relift the seat 5-25 times every work day. I tried to find a replacement cylinder but because of the size (it's way smaller than the standard) I couldn't. So I bit the bullet and shelled out another $200+ for a replacement. I've had this one less than 4 months and here we go again. I'm nowhere NEAR the weight limit for the chair but I've had to raise the seat up today alone 14 times and counting.
Good quality chair - same as what was observed / tested / chosen on the Staples showroom floor. The seat and back allow good flex which for me helps manage / mitigate pain in my lower back and tailbone regions. Headrest is attached in place but can be tilted it's location is comfortable if I want to lean my head all the way back / rest my head and neck.
The firm mesh offers great support and has in an almost mystical fashion heightened my productivity. Can it be that mere furniture is capable of inducing a higher and more effective state of being? Apparently so.
