5 "Really great, fit in a very small corner." Mrs Warry 24 November 2020 These are a perfect size, as they hold well over one laundry load each, and they do indeed stack well. The design is perfect for us, they just sit in a corner beside some drawers. We had tried lots of other types, but they either fell apart (metal frame ones) got chewed by the dogs (wood or wicker) or were too soft and got made into impromptu dog beds over night! (Fabric ones, even the ones that were supposed to stand up). These are the first that haven't been trashed within weeks. Highly recommended if your dogs have access to the laundry baskets.
