发明名称 Frameless chair
摘要 A substantially spherical frameless chair comprising an at least partially gas permeable outer liner, an at least partially gas permeable inner liner positioned inside of the outer liner, and a plurality of polyurethane foam pieces having a density between approximately 1.0 and approximately 3.0 pounds per cubic foot retained within the inner liner. The outer liner includes a first end component having a substantially circular peripheral geometry, a second end component having a substantially circular peripheral geometry, and an intermediate component having a substantially rectangular peripherical geometry wherein the first and second end components are secured to the intermediate component to, in turn, form a substantially spherical outer liner. The inner liner includes a first end component having a substantially circular peripheral geometry, a second end component having a substantially circular peripheral geometry, and an intermediate component having a substantially rectangular peripherical geometry, wherein the first and second end components are secured to the intermediate component to, in turn, form a substantially spherical inner liner.
