First off the base was bent or not put on properly so I couldn’t attach the middle part without hammering it into place. The extendable cover for the middle part was missing, which isn’t totally necessary but would have been nice to have... And last but not least the holes drilled in the bottom of the chair where you are supposed to attach the seat to the base don’t match up with anything at all so I was only able to attach 2 of the bolts!! I wouldn’t have minded any of this for a reasonable price but to charge $90 for missing parts and poor construction is just silly
