Good quality and arrived quickly
Color: Black
I was very pleased with how easy this chair was to set up. Affordable, arrived quickly. The only reason it isn’t 5/5 is because on of the arms had a small dent, possibly due to not enough bubble wrap during shipping. Other than that, the quality is great.

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.
