An improved insulated cover for removable mounting onto a spa or hot tub or the like, wherein the cover is hinged to accommodate folding of the cover to a compact size and shape suitable for convenient shipment and/or storage. The cover comprises a foldable base including a pair of structural membranes formed from a relatively high tensile strength fabric and sewn together on a midline to define a central hinge, and secured together at their peripheries to defined a pair of pockets within which are mounted a pair of insulation panels of relatively stiff foam or the like. In some embodiments, a foldable frame ring formed in hinged or separable half sections may be mounted to the structural membranes at the peripheries thereof. A decorative top sheet is stretched over the foldable base, and a peripheral margin thereof is wrapped over the periphery of the base and radially constricted for retention thereon by a drawstring or the like.
