Abstract

Some embodiments of disclosed pillow comprise a first sleeve within which is retained a plurality of loose pieces of filler material, a second sleeve in which the first sleeve is received, and a unitary piece of foam retained between the first and second sleeves. In some embodiments, the unitary piece of foam comprises viscoelastic foam, and can be elongated to run along a side of the first sleeve, can be substantially flat to cover a face of the first sleeve, or can take other shapes and be located in other positions as desired. Also, in some embodiments the unitary piece of foam is shaped to mate with the first sleeve. Additional unitary pieces of foam can be located adjacent the first sleeve and can be retained between the first and second sleeves to provide pillows having other support and cushioning characteristics.

a rear side of the pillow opposite the front side;

and

a second piece of elongated and unitary piece of foam extending along the rear side and the sleeve of the pillow.

17. The pillow of claim 16, further comprising a pad of material covering a surface of the sleeve and extending between the first and second pieces of foam.

18. The pillow of claim 10, wherein the piece of foam has a crescent-shaped cross-sectional shape.

19. The pillow of claim 18, wherein the piece of foam receives a portion of the sleeve.

20. The pillow of claim 10, wherein the piece of foam is shaped to mate with a portion of the sleeve with the plurality of loose pieces of filler material therein.

21. The pillow of claim 10, further comprising a pad of material covering a surface of the sleeve.

22. A pillow, comprising:
