There is filling in at least the three chambers of the lower layer and in at least the two chambers of the upper layer, with no filling in the center chamber of the upper layer.
1. A multi-layer pillow, comprising:
an upper pillow layer which includes at least two chambers in addition to a center chamber, wherein the center chamber is surrounded by said at least two chambers, such that the center chamber does not extend to an edge of the upper pillow layer;
a lower pillow layer which includes at least three chambers arranged side-by-side, wherein the first and second layers have approximately the same outline and are secured together around the peripheries thereof; and
filling in the three chambers in the lower layer and in the at least two chambers of the upper layer, wherein the center chamber has substantially no filling therein.
2. The pillow of claim 1 , wherein the chambers in the lower layer are substantially identical in size and configuration.
3. The pillow of claim 1 , wherein the chambers in the lower layer extend laterally across the width of the pillow.
4. The pillow of claim 1 , wherein the chambers in the lower layer extend longitudinally along the length of the pillow.
5. The pillow of claim 4 , wherein the chambers in the upper layer are defined by connections which extend from the corners of the pillow toward opposing corners, terminating at the center chamber.
6. The pillow of claim 5 , wherein the connections are lines of stitching.
7. The pillow of claim 5 , wherein the connections are baffle members.
8. The pillow of claim 1 , wherein the center chamber is substantially circular in outline.
9. The pillow of claim 1 , wherein the chambers in the upper layer are defined by connections which extend laterally of the pillow, which bisect the pillow in two laterally extending sections.
10. The pillow claim 9 , wherein the connections are lines of stitching.
11. The pillow of claim 9 , wherein the connections are baffle members.
12. The pillow of claim 1 , wherein the chambers in the upper layer are defined by connections which extend longitudinally of the pillow, which bisect the pillow into two longitudinally extending sections.
13. The pillow of claim 1 , wherein the center chamber is defined by a line of stitching.
14. The pillow of claim 1 , wherein the upper layer includes two upper sheet members and the lower layer includes two lower sheet members.
15. The pillow of claim 1 , wherein the upper layer includes an upper sheet member and the lower layer includes a lower sheet member, and wherein the upper and lower layers share an intermediate sheet member.
16. The pillow of claim 1 , wherein the quantity of filling differs between those chambers which have filling in them.
17. The pillow of claim 1 , wherein the type of filling differs between the chambers which have filling in them.
