G'day Amy,

Unfortunately, there is no volume measure supplied on the Popup Laundry Basket and we're not able to check as they don't hold water! Based on items of a similar size we'd say ballpark volume it is about 50L. 

G'day Cathy, 

I've just had a go of this myself in store, and you can definitely stack the Pop Up Laundry Baskets inside each other when they're popped up, and that height measures 29cm. You can also stack them together when they're popped down, and that height is 15cm.
