Great frame for the money, went together quickly and without issue with two people with two Allen wrenches.  We are using it with the low profile metal box spring also on Wayfair, which works perfectly with our (king) mattress height.  My husband and I are about 425lb combined and often have a tiny human in bed with us, and the frame is solid and silent.  The shipping box was gauged when it arrived so I was worried that there might be damage but that thing was packed perfectly with lots of foam and cardboard to protect it.
