The chair arrived with the plastic handle broken off...the handle on the lever used to raise/lower the seat.   I didn't really notice it until the chair was assembled.  Wayfair arranged for a replacement seat plate, the big metal piece that sits on top of the base and underneath the seat.   The new part arrived, and the handle on it was attached, but scuffed pretty good.  And so far, I have had no luck disassembling the chair to swap out the seat plate.   I can't get the old one off of the gas cylinder used for the height adjustment.  I am considering if I should just live with the lack of the plastic handle, but I paid a bit more for what I thought would be a higher quality chair vs. ones I looked at in local stores.
