Abstract:
A modular sleep system has a foundation unit, an support unit having an innerspring and a support surface covered with a friction material, and a comfort unit having compressible material encapsulated in a woven upholstery material which is engaged by the friction material on the support surface of the support unit to prevent lateral movement or sliding of the comfort unit relative to the support unit, without any fasteners between the support unit and the comfort unit. The comfort unit can be lifted vertically off of the support unit without release or use of any fasteners, to be turned over, fluffed or exchanged for a different comfort unit having different layers of internal materials, feature layers, and support characteristics.
