This is my third order from Wayfair and although there was a missing component (which is rare) it was incredibly easy to resolve the issue.  Pay close attention to the hole alignment on the framing before tightening the bolts or you might find you need undo and rebuild the unit.  I bought two of these, and on the first one, I didn’t note that some of the bolt holes were facing in the wrong direction which meant the cross bracing struts didn’t fit.  Once I realised my mistake, it only took a fraction of the time to build the second unit.
