Don't waste your money.  We bought 4 of these chairs about one year ago.  Six months later we started having problems.  Now all 4 chairs will not stay in the down position. The hydraulic cylinder is very poor and I checked with Wayfair and they didn't respond to the problem. These chairs are made in china so we can't get any warranty. I would gladly sell these 4 chairs if I could.  They are worthless now.
