Abstract: Methods of compressing and sealing a plurality of mattresses in an air-impermeable, pliable outer container; and assemblies comprising such a plurality of mattresses. The plurality of mattresses may be rolled into a cylindrical shape for transport from a manufacturer to a distribution center or a retail location. Each mattress may be enclosed in an air-permeable, pliable decorative container that may be suitable for display or transfer to customers. The methods and the assemblies may allow greater efficiency in shipping mattresses to a distribution center or a retail location, and/or greater efficiency in preparing mattresses for display or transfer to customers of the retail location.
