Never used before, like brand new. Clean and ready for pick up!
Seat back is adjustable to height, moves up and down. Seat bottom can move in and out for someone with longer legs. Arm rests adjuat in height and the arm rests themselves can rotate a full 360 for a normal chair feel and again to extend forward for your wrists to rest on-- which is helpful in preventing carpal tunnel. Entire chair also adjusts its height. Wheels all work fine and chair is very comfortable as well. Message me on here if you're interested please.
As for myself, I got it as a gift and it just isn't something I need right now.
