  • Patent number: 7346948
    Abstract: A basic version of the Bed Loungeā„¢ includes a removable, inter-changeable, and washable fabric slip cover enclosing a foam, fiber, filled-pillow, layered padding over a flat light-weight inner body/frame structure, forming a layered composite that is exceptionally lightweight (2-3 lbs.), extremely durable and yet highly comfortable and supportive to the upper body of the user. Due its compact size, the basic bed lounge can be used on existing seating and furniture to augment support and comfort. It has the ability to be flattened to a very low profile so it can be easily carried in one hand, slung over the shoulder, hung like a suite bag on a hanger in the closet and stored under furniture, under a bed or in an automobile trunk for use when traveling.

  • Patent number: 5231714
    Abstract: A support member has an enlarged rectangular shaped wall with an inner side and an outer side and four side walls extending from the inner side with free edges spaced from the enlarged rectangular shaped wall forming a rectangular shaped opening large enough to receive and support a mattress on the inner side of the enlarged rectangular shaped wall between the side walls. The enlarged rectangular shaped wall and the four side walls of the support member are formed of layers of fibrous material such as paper or fiberboard glued together. The enlarged rectangular shaped wall and the side walls of the support member are strong enough to allow the support member to be supported by the edges of the side walls on a surface and to support a mattress on the outer side of the enlarged rectangular shaped wall for sleeping purposes thereby forming a foundation for the mattress.
