Patent attributes
An improved multiple chambered maternity mattress (10) is specially configured to include a bellows (24) for providing fine-grained adjustability of size and firmness of its centrally disposed womb well region (AWW). The bellows (24) consisting of a plurality of accordion-like sections which are interconnected to form a single expandable air chamber that is inflatable under the control of the user while actually in use via a remote control unit (16). The womb well is formed as a cylindrical cavity or opening (26) which extends for the full height of the mattress (10) such that the bellows (24) may change its effective height thereby establishing the physical size of the womb well for optimum user comfort and benefit. Low friction materials and/or coatings on the cylindrical cavity walls (28) assure minimal friction of the contacting surfaces and bellows tips assuring an infinitely fine height/size/firmness adjustment.
