Abstract
A mattress assembly and system adapted for specialized use where bending is required and comprising a top pad formed of two layers of relatively soft foamed plastic between which a load-distributing mesh sheet is bonded to also secure said layers together, in combination with a bottom pad of much firmer foamed plastic coextensive with and underlying the top pad and capable of preventing the assembly and system of pads from bottoming-out. The bottom pad also is connected to the top pad in a manner to prevent relative longitudinal movement therebetween, especially when the assembly and system are bent at localized locations incident to the mattress support on a bed being similarly bent such as in hospital use and in domestic convertible sofas.
