Nice chair, but beware. if you are over 6' tall and have a standard size desk, the chair will not lower enough for you knees to clear the bottom of the desk.  True Innovations the maker of the chair for Serta does offer a replacement gas lift for approx. $25 with shipping.  It is for that reason I have knocked off a star.  My prior intimation leather chair from Serta fell apart after 2 yrs, so lets hope this bonded leather lasts a bit longer.
