  • Comfortable chair with great back support.
Color: Black
Good: Quality of materials used to build this chair is good, it feels sturdy, I would prefer little stronger spring but it’s meets my expectations. Mesh fabric of seat and back makes it easy to maintenance and keep the overall chair weight low. Best: Back support is great especially for tall person 6’+, and neck support works as expected, plus it can be adjusted to support your neck. Bad: The default position for hand rest is little high, may be it just me but sometime it causes pain in my shoulder . you can move it up though which is not that useful in my case. The seat depth is little less at least by 2-3 inch, I would prefer little deeper seat so it supports thigh better. Overall this chair meets my expectations, it is sturdy, thoughtfully designed and can be used for sitting long hrs. ... show more

  • Comfy but lower to the floor than I like
Color: Black
The chair was relatively easy to assemble. I would recommend doing inventory of the parts first, as a friend had a missing part in their package; I did not. Chair support: the back support on this chair is good, but not as adjustable as other chairs I have tried in different working environments. It does what I need it to do. The cushioning is quite durable so far, with consistent use. Height: my biggest issue with this chair is with the height off of the ground. And for this reason, I would not buy it again. The highest setting is much lower than I would normally have my chairs. I like to be a little higher off of the ground. I would search for a chair that set higher than this one. But this really is the only issue I have with the chair. Otherwise, it meets my needs very well. Cleaning: The backing of the chair responds very well to using canned air dusters. And the seat wipes clean with a damp cloth, as does the "chrome" pieces. For the right person, this is an amazing chair, as it provides good support for the price. However, it is not right for me and I will be looking at a different type of chair the next time I buy. ... show more
