My hubby bought a big heavy duty cardboard cylindar from Home Depot that is used to form cement posts. Then he cut it into 1 foot deep sections. I spray painted the outside and he attached them together and to the wall using L brackets.
It has worked out great for getting random toys off the floor. However, I think I need a whole wall of them because if you look right next to the circle storage you’ll see the beginning of a whole row of ikea containers full of stuff on the floor.
