This product is absolute garbage.  It is advertised as easy to assemble, but takes at least 4 hours (and I am very mechanical)  holes do not match up so you have to force the set screws in,making product unsafe. If I had not spent so much time trying  to assemble, I would sent back but do not want to take the time to repack it.  IT IS IN THE TRASH NOW- DO NOT BUY THIS OR ANY OTHER PRODUCT- ABSLOUTELY TERRIBLE QUALITY!!  WAYFAIR SHOULD BE ASHAMED TO DISTRIBUTE THIS BRAND
