Abstract
One exemplary aspect of the present disclosure relates to, among other things, a tunable cushion including a core made of a polymer material, and at least one topper layer adjacent the core, which is also made of a polymer material. Further, the core and the at least one topper layer provide a cushion assembly having a support factor of less than or equal to 4 with an Indentation Load Deflection (ILD) determined using a 4 inch batt sample of the cushion assembly.
Claims11
A tunable cushion comprising:
- a core made of a polymer material;
- at least one topper layer adjacent the core, wherein the at least one topper layer is provided by a three-dimensional netted layer consisting of a plurality of helically arranged thermoplastic resin filaments, each of the thermoplastic resin filaments being partially thermally bonded directly to at least one of the other thermoplastic resin filaments such that the thermoplastic resin filaments are randomly entangled with one another;
- wherein the core and the at least one topper layer provide a cushion assembly having a support factor of less than or equal to 4 with an Indentation Load Deflection (ILD) determined using a 4 inch batt sample of the cushion assembly.
A tunable cushion comprising:
- a core made of randomly oriented polymer fibers interlinked with a polymer binder material;
- a first topper layer adjacent a first side of the core;
- a second topper layer adjacent a second side of the core opposite the first side, the first and second topper layers each provided by a three-dimensional netted layer consisting of a plurality of helically arranged thermoplastic resin filaments, each of the thermoplastic resin filaments being partially thermally bonded directly to at least one of the other thermoplastic resin filaments such that the thermoplastic resin filaments are randomly entangled with one another;
- a tuft extending through the core and the first and second topper layers to provide a tufted cushion assembly having a tufted height and a density within a range of 1.0-3.0 pounds per cubic foot (pcf);
- and
- wherein the tufted cushion assembly has a support factor of less than or equal to 4 with an Indentation Load Deflection (ILD) determined using a 4 inch batt sample of the tufted cushion assembly at the tufted height.
