US Patent 7346947 Pillow with central area having lower fill volume

The pillow comprises four substantially identical fabric sections arranged in registry and secured together around the peripheries thereof. A line of stitching connects the middle two layers, defining a circular area in the center of the pillow. The pillow is filled between the middle two layers from the line of stitching to the peripheral edges of the fabric sections. Filling is also present between the upper fabric section and one of the middle fabric sections, and between the lower fabric layers and the other middle fabric section, resulting in a pillow which has less filling in the center thereof.
