Ktaxon 59"x21"x11.5" Heavy Duty 5-Tier Wire Shelving Rack Adjustable Shelf Storage, Black

these are affordable and they're very sturdy. I put mine up in about 10 to 15 minutes tops. I bought five of larger sized ones for my kitchen and closet. I like that it comes in the color gray because the stainless ones are too shiny and I didn't want to put black in my kitchen. I do have a black one in my bathroom that I bought 5 years ago same brand and they all work great. I highly recommend these wire shelving racks...

I had been looking at options for shelves in my closet where I have one shelf across with 32" of mostly wasted space above it. Other shelving options had me well over $100. On sale, these shelves were the perfect fit at a tremendous bargain. They were exactly the depth of the existing shelf (11-1/2") and, put together as in the photo, I had 21" remaining of width where I put some tall objects (on the right, out of the photo). Now I can pack away a lot more clutter from my small house so I don't look so much like a hoarder. :) They're sturdy and the adjustable feet helped to make them so: the existing shelf isn't perfectly flat but now all legs are solidly on it. Here's the thing to know when assembling: the "lip" on each shelf should face up not down. This is not in the instructions. If you try to position the lip facing down, the round hole on each shelf corner won't fit over the plastic connector. Can be assembled in many configurations. You'll see I put them together in a way not shown. Super happy!
