8. The pillow of claim 1 , wherein approximately 16% to 20% of the plurality of loose pieces of filler material includes lengths longer than about 2 cm.
9. The pillow of claim 1 , wherein approximately 38% to 42% of the plurality of loose pieces of filler material includes lengths between about 1 cm and about 2 cm.
10. The pillow of claim 1 , wherein approximately 38% to 42% of the plurality of loose pieces of filler material includes lengths shorter than about 1 cm.
11. The pillow of claim 1 , wherein the filler material further includes a plurality of balls.
12. The pillow of claim 1 , wherein the filler material further includes highly-elastic foam.
13. A pillow comprising:
a first layer of viscoelastic material; and
a second layer of viscoelastic material, the first and second layers coupled together to form a cavity therebetween;
wherein a plurality of loose pieces of filler material is positioned between the first and second layers and is enclosed within the cavity.
14. The pillow of claim 13 , wherein the first and second layers of viscoelastic material are sewn together.
15. The pillow of claim 13 , further comprising a cover substantially enclosing the first and second layers of viscoelastic material and the plurality of loose pieces of filler material.
16. The pillow of claim 15 , wherein the cover comprises a resealable fastener through which access to the first and second layers of viscoelastic material is obtained.
17. The pillow of claim 13 , wherein the viscoelastic material of the first and second layers has a density between about 30 kg/m 3 and about 140 kg/m 3 .
18. The pillow of claim 13 , wherein the plurality of loose pieces of filler material has a nominal length between about 0.6 cm and about 2 cm.
