An apparatus and method of improving the efficiency of lymphatic and venous circulation of the lower body using a seat cushion composed of breathable open celled polyurethane fabric with strips of dense foam to provide compression with constant shear force to interstitial tissue. The strips of dense foam apply a shear force onto the interstitial tissue, which positively affects the thixotropic properties of the interstitial fluid in the congested fibrotic tissue and thereby decreases the viscosity of the interstitial fluid over time. The strips of the dense foam are designed in such a pattern that channels interstitial fluid away from the dorsolateral and dorsomedial lymphatic territory of the thigh to the lymphatic capillary network on the lateral border of the thigh and lower lymph quadrant of the trunk.
