I ordered some wire mesh shelves for my kitchen, “Seville Classics 2-Tier Iron Mesh Adjustable Floating Wall Shelves, 36″ x 14″, Satin Pewter.” They looked cool.
Unfortunately, their manufacturing tolerances were way off. The shelves tilted downward into the room. A lot. The front edge of the shelf was about 2cm (almost an inch) lower than the back. Stuff on the shelves would work their way to the edge and then fall off.
My first instinct was to send them back. I liked the look, though, and I’d put a bit of effort into getting them properly mounted.
I looked through the reviews on Amazon, again, and found that several people had had the same problem. A clever solution was to put wine corks behind the shelf supports to force them toward level. Unfortunately, that would make the shelf work as a lever against the wall, pulling the shelf bracket out of the wall. The mounting hardware wasn’t that great, and one of the screws was defective, so I really didn’t want to stress it further.
My solution was to print some small parts on the 3-D printer that slide onto the horizontal members of the shelf brackets and level the shelves.
I guess I’d have to advise folks to avoid this product, but if you love the design (or already own them) and have a 3-D printer, this solution seems to work well.
I’m uploading the files to Thingiverse if you need your own.
Edit 13June2018: My fears about the cheap hardware were well-founded. The included screws pulled free from the included hollow wall fasteners; I was nearby or I would have had a mess of broken jars and baking ingredients. The problem wasn’t too much load or bad installation, but outright faulty hardare. Simply replacing the screws and wall fasteners with proper quality components seems to have fixed it. If you’re installing these shelves and planning on putting any significant load on them (and I’m only talking flour, rice, and baking powder, not books or liquids), do yourself a favor and throw away the included fasteners in favor of proper gear.
