Replacement tube for the Deluxe+ Dock. A new tube will help refresh a much-loved dock. 100% hygienic polyester fibers inside a non-woven tube cover. The inner tube rarely needs washing. Shaking and ventilating is usually enough. If washing the tube, use a washing bag. When washed, the tube should be tumble-dried at low heat. If still somewhat damp, lay flat to dry. *Please note that Deluxe+ replacement parts are only to be used with Deluxe+ docks, and Grand replacement parts are only to be used with Grand docks. Also, replacement parts should only ever be used as part of a fully assembled DockATot.
