You get what you pay for and I didn't pay much. My prior office chair broke after several years of use. I purchased this inexpensive replacement expecting it to offer the same level of comfort as my previous chair which looked very similar and which I also purchased from Staples. The new chair however has a very different feeling hydraulic system and does not seem to offer as much support during swaying or rotational movement. Not a bad chair overall but just not quite all there as far as support.
