Probably. I think I went into a rolling workbench deep dive.
Need to do some drawing up and measuring, but I may have one on the ground and one above which would mean a more proper draw structure equally until I have time to do some proper organising one can sit on top of the other for a while.
I still wonder about trying to make a toddler crap draw for our sofa. That was a very smart and simple idea.

Slightly cheeky (although personally I feel I spend plenty of money there) but you can probably get something suitable on the IKEA spare parts site

Any old castors from B&Q would do. If they are just pulling in and out, then they don't need to pivot. I made a pull out drawer for toddler crap to go under the sofa using non-pivoting ones. Works fine and reduces the stack height. The pricey ones you saw were probably industrial ones with proper bearings in the pivot part.
