Abstract: Left and right base components each have upper and lower surfaces in a generally horizontal orientation, an exterior edge, a forward point, a rearward point, and an interior edge. Each base component has a generally oval central extent, a forward extent, and a semicircular rearward extent. A support component in an arcuate configuration is positionable in a generally vertical orientation. The support component has inner and outer faces and upper and lower edges. The upper edge is perpendicular to and integrally formed with the base components at the exterior edge. The support component has terminal ends located adjacent to the base components. The support component has an arcuate forward section between the base components. The lower surface of the base components is spaced from the upper surface of the forward section by an elevational space.

Abstract: A left base component and a right base component with each base component having upper and lower surfaces. Each base component has an exterior edge, a central front point, laterally spaced rear points and an interior edge. Each base component has a rectangular central extent and arcuate forward extents and a semicircular rearward extent. The system also includes a support component in an arcuate configuration positionable in a generally vertical orientation. The support component has inner and outer faces. The support component has upper and lower edges. The upper edge is perpendicular to and integrally formed with the base component at the exterior periphery. The support component has terminal ends located adjacent to central regions of the rectangular central extents. The support component has an arcuate forward section between the base components. The lower surface of the base components is spaced from the upper surface of the forward section by an elevational space.

Abstract: An arcuate base section with upper and lower surfaces separated by a thickness has an arcuate exterior periphery with a central front point and laterally spaced rear points, an arcuate interior periphery generally concentric with the exterior periphery, a width and a depth. Two lateral support sections and a central support section are in an arcuate configuration and have inner and outer surfaces separated by a thickness. The support sections have free upper edges and lower edge separated by a height. The lateral support sections are perpendicular to and integrally formed with the base section at the exterior periphery adjacent to the rear points. The central support section is perpendicular to and integrally formed with the base section at the interior periphery adjacent to the central front point. The system is fabricated in one piece of a material with limited flexibility and elasticity.
