I just contacted Wayfair to return this item for a refund.  I have purchased a lot of furniture from them and never had an issue with assembly or inferior product.  However, this daybed had serious quality control problems.  Some of the bolts are supposed to screw into pre-threaded inserts in the tubular steel.  Some of these threads were cut so crooked there was no way to align the bolt and screw it in, plus the metal is so hard that there is no "give" in the threads.  One tubular piece had a large dent in it, and many of the holes were slightly mis-aligned so the bolts had to go in at a slight angle, making it very difficult to get the bolt in all the way.  I needed a rubber mallet to align the holes on the mattress support.  Altogether an inferior product.  And after almost a month-and-a-half the replacement parts were still out of stock.  Maybe I got the last bed off of the production line, or all the mistakes from the factory floor!
