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.

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.

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.

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".
