Fill composition for reducing filling weight of resilient products

A method of filling a soft casing for producing a pillow, the method comprising:

• selecting a fill material comprising a blend of a first quantity of fibers having a denier of 3D and a second quantity of fibers having a denier of 7D and each of the first quantity and second quantities of fibers comprising fibers of a same average length of 64 mm;
• mixing the first and second quantity of loose fibers;
• and
• filling a soft casing defining dimensions of the filled pillow with the fill material comprising the loose fibers.

A fill composition for a soft casing, the fill composition comprising:

• a first fiber quantity, wherein the first fiber has a first denier and first length;
• a second fiber quantity, wherein the second fiber has a second denier and second length, and
• wherein the first fiber quantity and second fiber quantity comprise polyester fibers,
• wherein the first denier of the first fiber is different than the second denier of the second fiber, and
• wherein the first fiber quantity and second fiber quantity are mixed together to form a loose fiber fill composition before or while filling the soft casing with the loose fiber fill composition
• wherein the fill composition consists essentially of a mixture of 3 denier (D) and 7 denier (D) polyester fibers wherein the first fiber quantity is the 3D fibers at approximately 80 w % of a total weight of the fill composition and the second fiber quantity is the 7D fibers at approximately 20 w % of a total weight of the fill composition and wherein the 3D and 7 D fibers are 64 mm fibers.
