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.

Wow Great Deal!

Color: Black

I have been using this chair for a month now and I am honestly impressed for the price I paid. I work from home so am using this chair 24/7. I had no issues with assembling it myself as a 35 year old female. Instructions were simple to follow and took me maybe 30 minutes to put together. Its sturdy and comfortable. I appreciate the padded arms and the seat bottom is also a nice thick cushion. Added bonus for the head rest and that it is adjustable. Definitely recommend.

Very comfortable office chair

This ergonomic office chair is very comfortable and has good lumbar support and a nice headrest. It includes all the necessary tools and takes about 20 minutes to fully assemble. The height adjust and recline features of the chair work smoothly and quietly. The seat cushion is nice and comfortable. The height-adjustable armrest is also a nice features of the chair. Overall, this ergonomic office chair provides relaxing comfort during long hours sitting with support for your bottom, back, head and arms. It's a good value for the price.

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.
