发明名称 Quilt-stitched internal mattress pillows
摘要 A mattress has a quilted internal pillow wherein one or more internal layers of material are quilt-stitched prior to encapsulation in mattress upholstery. The quilted internal pillow is positioned relative to a support surface of an innerspring or spring core of a mattress to provide support characteristics determined by the quilt stitch pattern. In a related method of manufacture of a mattress with an internal quilt stitched pillow, the layer or layers of the pillow are processed through a quilter stitching machine and then assembled in combination with a mattress spring core and upholstery. The quilted internal pillow may be located adjacent to the spring core, spaced from the spring core by other internal layers of material, or located adjacent to or within a mattress pillowtop, and in each embodiment on one or both sides of the mattress.
