Awesome chair so far
Color: Black
My old chair can go in the trash immediately because it set the bar so low (picked up from a giveaway - squeaked anytime it's leaned on, always sinking upon sitting on it). This Ergonomic chair blew it out of the water. Happy with this purchase. This chair took me an hour to assemble, which I expected. It feels extremely sturdy and comfortable. Lumbar support feels great! I love the various adjustability options this chair offers. Hope it lasts for many years.
By the way, I am 175 lbs, 5'10".

Good buy
Color: Black
Very comfortable. Solid chair. Lumbar support helps a lot. Posture in this chair is great. Lots of support. Seems like a relatively skinny chair though - I wouldn't imagine it to be comfortable for a larger person.

Check components for imperfections
Color: Black, Color: Black
Just finished putting the chair together, and while there were some nice touches (gloves to wear while assembling) and manual very easy to understand, there are more steps than are customary for a basic chair. However, two main gripes are (1) bought Saturday for $129.99, today it is listed for $89.99 (2) out of the box, the mesh back of the chair has a small tear in it. Unsure if it will end up being a long-term issue, but irritating all the same.

Amazing chair
Color: Black
Going from a regular office chair to this majestic heavenly office chair, my body hasn't felt better. As a person who is rather on the large side (6'2, 175 pounds), so this chair good butt cushioning, adjustable armrest, the adjustable headrest made this purchase an very good one. I move constantly on chairs so when i found out tthis chair can adapt to my position with a few tweaks i instantly fell in love. Considering that I have jumped and stood on the chair quite the number of times and it still is holding its form just speaks to its sturdiness. I dont believe in buying extremely expensive chairs as a high quality one like this has everything you could wish for.
