Pillow top for a cushion
View Patent ↗A support cushion has an elastic core having a first surface, a second surface and a thickness defined by the first surface and the second surface. A first cover portion substantially entirely encloses the elastic core. A pillow top surface is positioned adjacent the first surface of the elastic core. The pillow top surface includes a plurality of foam portions. A second cover portion at least partially covers the pillow top surface and the second cover portion attached to at least one of the first cover portion and the elastic core.
1. A pillow top layer for a support cushion, the pillow top layer comprising:
a first elongated foam portion having a first side opposite a second side, and upper and lower faces extending between and connecting the first and second sides;
a second elongated foam portion having a third side opposite a fourth side, and upper and lower faces extending between and connecting the third and fourth sides, the first and second foam portions being positioned together in a generally parallel arrangement such that one of the first side and second side is generally parallel and adjacent to one of the third side and fourth side, the upper faces of both first and second elongated foam portions collectively defining a substantially planar top surface of the pillow top layer; and
a cover that substantially covers the first elongated foam portion and the second elongated foam portion wherein the cover substantially separates the first and second elongated foam portions,
wherein the cover, the first elongated foam portion and the second elongated foam portion define a generally contiguous and substantially gapless structure, and
wherein the pillow top layer is positioned adjacent an elastic core having length and width dimensions.
2. The pillow top layer of claim 1 , wherein at least a portion of the cover generally separates the first and second elongated foam portions from the elastic core.
3. The pillow top layer of claim 1 , wherein the elastic core has a greater hardness than the first and second foam portions.
4. The pillow top layer of claim 1 , wherein the first and second elongated foam portions comprise viscoelastic foam.
5. The pillow top layer of claim 1 , where the first and second elongated foam portions have a thickness of between two and seven centimeters.
6. A pillow top layer for a support cushion having an elastic core having a length and a width wherein the length is greater than the width, the pillow top layer comprising:
a plurality of foam portions, each of the plurality of foam portions having a length, a width, and a thickness, the width of each foam portion is greater than the length of each foam portion, wherein adjacent portions having substantially planar facing sides positioned side-by-side when viewed from above to define a substantially gapless structure; and
a cover extending between adjacent foam portion of the pillow top layer that generally covers the elastic core and the foam portions.
7. The pillow top layer of claim 6 , wherein the cover defines at least one sleeve that substantially covers at least one of the plurality of foam portions.
8. The pillow top layer of claim 6 , wherein at least a portion of the sleeve generally separates the first and second elongated foam portions from the elastic core.
9. The pillow top layer of claim 6 , wherein the elastic core has a greater hardness than the plurality of foam portions.
10. The pillow top layer of claim 6 , wherein the plurality of foam portions comprise viscoelastic foam.
11. The pillow top layer of claim 6 , where the plurality of foam portions each have a thickness of between two and seven centimeters.
12. The pillow top layer of claim 6 , wherein the plurality of foam portions substantially cover the elastic core.
