Abstract:
1. A cushioning support device for use in supporting a human body, comprising: a first polyurethane foam, wherein the first polyurethane foam has a non-slip sheet attached on a bottom surface of the first foam; a second polyurethane foam, wherein the second polyurethane foam has a resting sheet attached on a top surface of the second foam sheet; and a plurality of compound pressure-redistributing bodies, wherein each of the compound pressure-redistributing bodies comprises an inner foam and a solid gel attached on a top surface of the inner foam; wherein the first and second polyurethane foams are arranged one over another in a top-down manner into a stack and are welded together to form at least one receiving compartment; at least one large circular internal pocket coupled to at least one small circular internal pocket with at least an interconnecting passage is disposed in the receiving compartment; wherein the large circular internal pocket receives a first one of the compound pressure-redistributing bodies and the small circular internal pocket receives a second one of the compound pressure-redistributing bodies; wherein a volume of the first one of the compound pressure-redistributing bodies is smaller than a volume of the large circular internal pocket and a volume of the second one of the compound pressure-redistributing bodies is smaller than a volume of the small circular internal pocket to accommodate the compound pressure-redistributing bodies for shape alteration; wherein a top surface of the large circular internal pocket is larger than a top surface of the small circular internal pocket; wherein one end of the interconnecting passage is in connection with a periphery of the large circular internal pocket and the other end of the interconnecting passage is in connection with a periphery of the small circular internal pocket; wherein the large circular internal pocket, the small circular internal pocket and the interconnecting passage are enclosed by a weld line; wherein a lateral wall is extended along the weld line and is connected to a bevel, wherein the bevel is spaced from the weld line; wherein the lateral wall is perpendicular to the top surface of the large circular internal pocket and the top surface of the small circular internal pocket; wherein the weld line is formed in a groove surrounding the combination of the large circular internal pocket, the small circular internal pocket and the interconnecting passage.
