Abstract:
An improved camping mat or camping chair comprising, in combination:a flexible, substantially air tight body having an upper sheet and a substantially coextensive lower sheet, and each of said upper sheet and said lower sheet having an inside surface and an outside surface and peripheral edges sealed together to define a substantially air tight pad receiving cavity between said inside surfaces thereof;an air transfer valve coupled to one of said upper sheet and said lower sheet for selectively providing air flow communication between said pad receiving cavity and regions external said body member in an open position and selectively blocking the flow of air into said pad receiving cavity from regions external said cavity in a closed position;a first pad member in said pad receiving cavity and substantially coextensive with said upper sheet and said lower sheet, and said first pad member comprised of an open cell foam having a first preselected thickness and having a first surface adjacent to and bonded to said inside surface of said lower sheet substantially throughout the extent thereof, and a second surface spaced from said first surface;a second pad member in said pad receiving cavity intermediate said second surface of said first pad member and said inside surface of said upper sheet and said second pad member having a first surface adjacent said second surface of said first pad member and a second surface adjacent said inside surface of said upper sheet and bonded thereto, in at least portions thereof said second pad member having a second preselected thickness less than said first preselected thickness of said first pad member and having walls defining a plurality of pad cavities extending from said second surface toward said first surface, and said upper sheet extending into said pad cavities to define a plurality of air insulating chambers on said outer surface of said upper sheet.
