This shelving unit is made by a company called “Muscle Rack, which is appropriate, because you can’t assemble it without a Herculean display of brute force.

The instructions say “tap lightly to seat the rivets”. 
If by “tap lightly”, they mean “using a hammer or rubber mallet, wail on the cheap piece of steel (is it even steel) with Muppet like abandon, until either your hammer breaks, or the unit is pounded flat,” then I guess they were accurate. 

The rivets Will. Not. Fit. In the holes. 

Do not buy.
