An insulated hollow cushion has a neck strap (30), an interior portion (72) sufficiently large to accommodate a portable heating source and/or hot and cold foods (74, 76), two side slits through which hands can be inserted for warmth, sealable flaps (16, 20) for closing the side slits when insulation is desired, a slit (36) at the top of the cushion for insertion of items into the cushion's interior, a closeable top flap (28) to seal the top opening for insulation purposes, and a closeable top small flap (56) to insulate the gap between a user's ankles when such user's feet are inserted through the top slit. The side flaps can be insulated so that they can be tucked into the side openings to narrow these openings to provide a tight seal when small hands are inserted into these openings. The insulating layer within the front (10) or the back panel can have multiple perforations (92) over an area thereof and this area can be covered, uncovered, or partially covered by a releasably closable flap (84), thereby to provide a "heat window" which allows maximum transmission of heat (or cold) from an internal hot (or cold) source, or partial transmission, or no more transmission than would occur through an intact insulated wall.
