Compared to my previous office chair this is an improvement with respect to the seat bottom. My previous chair had me gradually sliding forward which create back issues. As for the not so good the arms are fixed and are too high. I wish they were adjustable to better match my arm length and the height of my keyboard tray.
The chair is nice however it does not allow for my sister to sit correctly in the chair and rolls every time she tries to get in the chair. Need to rethink this chair for next purchase.
I purchased the chair and just finished putting it together. No issues with the assembly and I got it on sale at a good price HOWEVER this review is for anyone buying it online site unseen - THE FEATURES LISTED ARE NOT ACCURATE. I went by the store and sampled the chairs before I bought this thru the website so I'm perfectly happy with what I got but when I came home and read the description online I was floored. In short if you look at the feature list the following are not true - Lumbar support is not adjustable. There is NO headrest. Not sure what "multitilter" is exactly but this chair either tilts or doesn't no multi about it. The seat does NOT glide. The arms are technically adjustable but they are up or down you can't adjust the height.
The chair is very comfortable and easy to move on its five casters. I like the fact that the Arm Rests are moveable. The tension knob on the bottom of the chair is a little hard to adjust.
