My grandson and friend came by to set up the chair for me (I am 89).  .........It went okay at first , then ran into real problems with many of the screws that would only go halfway in.  They tried what they had across my good wood floors and it was not moving nicely either.  Finally they packed it up for return and they went to Office Depot to get me a good one for about $20. more and they had it together and running smoothly in short order!!  Other Wayfair items were fine.
