I bought this chair in white a little over year ago. I have to buy a new chair already. :-( 
At first, it was great and still is very comfortable but the hydraulic went out.  It will not stay in the height position I want it in. The leather will pick up stains and will not come out.  The seat is losing the firmness it had.  I am disappointed it didn't last more than a year.  If you are going to buy this chair I would recommend to buy the protection plan!
