This piece is not as sturdy as it looks, and the mounting hardware is terrible.  Molly bolts were inadequate and spun out when inserting the screw.  We had to use our own hardware.  The position of mounting holes is engineered terribly.  It should be in the metal frame structure, but instead is on the vertical shelf partition boards.  To make it worse, they are not on 16” centers, which would at least make the mounting on studs possible, adding to weight bearing capacity.  The style is great, and it looks terrific with the matching bench. I would have preferred it to be assembled by us, so we could have machined mounting holes where we saw fit.  “No assembly required” was NOT a positive feature in this case.  Also, note the bowed lower shelf in this picture.  How could they have gotten THAT wrong?
