We are using this chair at home and really love it since it has a strong mesh that handles the weight well and it also has number of great adjustments to to customize it according to your personal preference.
Assembly was straight forward and only one tool was required and provided. Total time @ 60 minutes. It's very light so it moves easily and is very comfortable to sit in partially due to the give in the mesh and also due to the multiple adjustment points available. I highly recomment this chair.
As other reviewers have stated this chair is poorly designed with insufficient adjustability for 6' or taller people as the headrest even at maximum height digs into your shoulder blades. Additionally I've found that the tilt adjustability cannot be fine-tuned enough. The most upright and forward position I find leans too far forward and brings the back and head rest too close to the body. But the next available locked position tilts it too far back.
I am absolutely certain that this chair was the cause of my neck pain that I suffered from for 1 year which started exactly 2 months after I started using this chair. At 5'8" The head rest is too low and constantly rolls backwards. Your neck ends up being curved back as you lean back and look up at your screen. I should have listened when I read that neck rests are not necessary on chairs and can cause weakening neck muscles. Even after countless massages the pain always returned after a couple of weeks So one day it dawned on me that my pain started around the time I got this chair. So I removed the head rest and things seem to be improving. I also find the bottom of the seat starting to sag after a year and so I had to put a thick cushion on it. I should have never listened to all the mainstream media reviews extolling the virtues of this 'high-quality yet affordable office chair'. They must have been paid to say it. I feel like a fool. My advice is for you not to become a fool like I did by buying this chair.
I've had this chair for over a year and tend to work very long hours at my desk. This chair is amazingly comfortable. I especially like the lumber and neck support - it feels like an expensive back/neck massage every day!
This chair has changed my life. No longer do I have lower back pain from sitting all day working. It looks stylish and beyond comfortable. I love the fact you can loosen (or tighten) up the back for the reclining feature to make it easier or harder for the back to recline. So glad I made this purchase!
