Abstract

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.

Claims

1. A frameless chair, comprising:

an at least partially gas permeable outer liner comprising;

a first flexible end component having a substantially circular peripheral geometry;

a second flexible end component having a substantially circular peripheral geometry;

a flexible intermediate component having a substantially rectangular peripheral geometry, the first and second flexible end components being secured to the flexible intermediate component;

an at least partially gas permeable inner liner positioned within the outer liner comprising;

a first flexible end component having a substantially circular peripheral geometry;

a second flexible end component having a substantially circular peripheral geometry;

a flexible intermediate component having a substantially rectangular peripheral geometry, the first and second flexible end components being secured to the flexible intermediate component; and

a plurality of polyurethane foam pieces retained within the inner liner.

2. The frameless chair according to claim 1, wherein the density of the polyurethane foam ranges from between approximately 1.0 and approximately 3.0 pounds per cubit foot.

3. The frameless chair according to claim 1, wherein the outer liner includes at least one seam having an outer surface and an inner surface, the outer surface of the seam being void of any exposed stitching.
