Nice chair, but two major mistakes. First, the chair sits too low (legs are too short) - needs to be raised about 2 inches. Also, the seating surface tilts slightly forward, when should be slightly rearward (for comfort). You feel like you will slide off it. At first, I suspected I assembled the legs incorrectly (back legs on front and vice-a-versa), but that was not the case. I will shim up the height using a half inch board (painted black) add stem roller casters to the front legs to attain the proper tilt.
