Ive put together many pieces of furniture successfully and this is the worst junk Ive ever seen. Quarter turn set screws extremely flimsy. Broke a few of them so dont have enough to complete the piece by attaching the top even if I wanted to. Based on how flimsy everything is there is no way I want to run my sewing machine on it. Im sure it would collapse upon me.  Garbage! Ill be contacting Wayfair for a refund.
