Empty Tupperware on the top, lids on the bottom. Add a $15 motion-activated, battery operated light on top. It will help you find the things that will inevitably fall off.

I had one of those and I used it for pots and pans. The least frequently used were in the back, the most frequently used in the front.

I'd put in larger kitchen equipment like stacked mixing bowls, stacked pots and pans, or maybe things like graters, hand mixers, or a food processor if you have one. Having small items like Tupperware are bound to get lost in there and it ends up being non-functional.

I think all the plastic containers could be nested and then you would have more space . I hve switched all of mine for glass and store those in a drawers with the lids attached. I need to know what you have to store and what the other storage is in the kitchen. I have had the metal ones before and actually cut out pieces of vinyl flooring to cover the shelves so stuff at least does not fall between the slats.I think the best is actually pots and pans stored there to free up storage for the plastic ware . I always tell my clients to take everything out of a cabinet and put back only what they actually use so at least start there IMO no one needs dozens of plastic containers at all. I have 3 with lids I use them when someone wants to takes leftovers .

Lazy susan corner structures often can't hold heavy things without sagging and catching. You'll know pretty soon if yours can take heavy things or light things.

You just need to organize it so you can turn it freely and find what you're looking for easily. I'd use it for larger items like a salad spinner, nested mixing bowls, pitchers, etc. Put the miscellaneous tupperware and lids in a drawer instead to make it easier to find what you need.

I had Tupperware in a lazy susan, and I hated it. When we remodeled, I designed the kitchen to make room for Tupperware in a drawer, which was awesome. Our current house doesn't have a lot of drawer space, so I keep storage containers in an upper cabinet - after thinning down to those we used most often.

What is on either side of the corner? Near the stove: great for pots and pans. Other options: canisters of dry goods (sugar, flour, etc), or small appliances. The best option depends on what you need most in that location.
