If you search around you'll be able to find a thread on here from the last couple years where everyone posted pics of their Expedit systems. It inspired me to go get one and we LOVE it. I have 16 squares. 12 are filled with Container Store sweater boxes, which fit perfectly. The other four are filled with books. Art supplies are on the top row, books on the third row, and toys on the bottom two rows. Toys are organized by type: kitchen, Fisher-Price, cars/trucks, wooden blocks, small legos, big legos, miscellaneous.
I think it's super easy to maintain and totally recommend it.
DH and I set it up together and it took us about 90 minutes. It wasn't hard, but it took two of us to hold pieces together to screw them together.
