Abstract
A cushion cover includes a one-piece knit fabric configured to at least partially surround a cushion, the cover including at least one graphic feature protruding from an associated surrounding area of the one-piece knit fabric. The at least one graphic feature is integrally knitted in the one-piece knit fabric and has a thickness at least about 2 times the thickness of the associated surrounding area of the one-piece knit fabric.
Claims20
A cushion, comprising:
- a cushioning element comprising a hollow-column buckling gel defining at least part of an interior of the cushion;
- and
- a cover on the cushioning element, defining an exterior of the cushion, and comprising:
- a one-piece knit fabric that covers a top surface and lateral surfaces of the cushioning element and has an elasticity that enhances a cushioning effect and/or a sensation of the cushioning element and enables a user to sink into the cushioning element;
- and
- at least one graphic feature integrally knitted in the one-piece knit fabric, having a thickness at least about two times a thickness of an associated surrounding area of the one-piece knit fabric and having a same elasticity as the elasticity of the one-piece knit fabric, the at least one graphic feature comprising a same material as a remainder of the one-piece knit fabric,
- wherein the cover further comprises at least six sides wherein one of the at least six sides is a base side, the base side comprising a base material joined to four lateral sides of the one-piece knit fabric by a zipper traversing edges between the base material and the four lateral sides of the one-piece knit fabric;
- wherein the zipper is positioned entirely on the base side;
- and
- wherein the base material is more rigid than the one-piece knit fabric.

A cushion, comprising:
- a cushioning element comprising at least part of an interior of the cushion and comprising a cushion material comprising a hollow-column buckling gel;
- and
- a cushion cover comprising an exterior of the cushion, the cushion cover including:
- a one-piece knit fabric completely covering a top and sides of the cushion material, the cushion material substantially filling a volume of the one-piece knit fabric, the one-piece knit fabric having an elasticity that enables the one-piece knit fabric to deform with a corresponding surface of the cushion material as the corresponding surface is deformed, enhances a cushioning effect and/or a sensation of the cushion material, and enables a user to sink into the cushion material;
- and
- at least one graphic feature integrally knitted in the one-piece knit fabric, the at least one graphic feature having a thickness at least about twice a thickness of an associated surrounding area of the one-piece knit fabric, the at least one graphic feature having an elasticity the same as the elasticity of the one-piece knit fabric, enabling the at least one graphic feature to stretch without deleteriously affecting a cushioning feel and quality of the cushion material, wherein the at least one graphic feature is comprised of a same material as a remainder of the one-piece knit fabric,
- wherein a greater of a width and height of the at least one graphic feature is at least 10 percent of a greater of a width and height of a side of the one-piece knit fabric on which the at least one graphic feature is knitted;
- and
- a base material joined to the one-piece knit fabric to cover a base of the cushioning element, the base material engaging four lateral sides of the one-piece knit fabric, wherein the base material is more rigid than the one-piece knit fabric.
