The grand finally, the hydrollic lift under the seat broke, some screws fell out, bearings crack, and rubber gaskets fell out, some greased particles under the chair.

The part that attaches the armrest to the chair is made of plastic and cracked, and the screws that are used to make that piece attach to the base of the chair keep coming out, so the arm of this chair falls off daily

It was wood and to raise and lower it, you twisted a big screw on the bottom of it.
