Milk crates zip-tied together on their sides so that a bench seat fits on top and red bins from Lowe's can slide inside them. I don't have any milk crates, though. I also don't know what "zip-tied" means. I would use different colors.
A multipurpose decor item, this DIY fabric pouf can be used as an ottoman, extra seating for guests or as a coffee table with a tray on top. Use a fun, patterned fabric that matches the other decor in your dorm room.
use plastic crates purchased from your local Walmart, plywood cut to fit the top, foam, fabric and a staple gun. Cute idea a classroom reading corner. The "seats" can lift off so you can use the crates for storage.
