  • Patent number: 5108094
    Abstract: The invention is directed to a comfort cushion adapted for use by a person standing for a prolonged period. The cushion causes increased leg muscle activity that results in increased movement of blood upward from the feet of the standing person. The cushion is composed of a wear layer which is resistant to abrasion from foot traffic and a base material which is substantially more compressible than the wear layer. The comfort cushion causes the foot to assume a slightly different angular relationship to the horizontal as compared with the conditions that exist when one is standing on a conventional flat floor. This, in turn, causes increased leg muscle activity.
