Abstract

A moldable seating system for use with a cushion comprising a moldable seat base and a moldable backrest. The moldable seat base comprises a central portion and a perimeter having a plurality of individually adjustable fingers extending there from. The moldable backrest comprises a moldable center backrest portion and a head support portion. The sides of the moldable center backrest portion comprise a plurality of individually adjustable fingers extending there from. Each of the individual fingers of the moldable seat base and the moldable backrest may be further divided into individually adjustable sections.

Claims

1. A moldable seat base comprising:

a central seat base portion comprising a front seat base portion and a perimeter;

a plurality of moldable fingers being attached at intervals along the perimeter.

2. The moldable seat base of claim 1 wherein the perimeter includes a cutout portion that does not provide moldable fingers.

3. The moldable seat base of claim 1 wherein each of the plurality of moldable fingers are independently adjustable.

4. The moldable seat base of claim 1 wherein each of the plurality of moldable fingers comprises a distal support zone, a moderate support zone and a severe support zone.

5. The moldable seat base of claim 4 wherein each of the distal support zone, the moderate support zone and the severe support zone are adjustable independently of one another.

6. The moldable seat base of claim 5 wherein the distal support zone comprises two independently moldable fingers to accommodate fine adjustment.

7. The moldable seat base of claim 1 wherein the each moldable finger has a length and a thickness and the thickness of each moldable finger tapers down along the length of the moldable finger.

8. The moldable seat base of claim 4 wherein the each of the moldable fingers has a thickness and a length and the thickness of each moldable finger tapers down along the length of the moldable finger in steps from the severe support zone to the moderate support zone and from the moderate support zone to the distal support zone.

9. The moldable seat base of claim 1 wherein the central seat base portion is moldable.

10. A moldable seat base comprising:

a central seat base portion comprising a front seat base portion, a perimeter and a cutout section opposite the front seat base portion;

a plurality of individually adjustable moldable fingers being attached at intervals along the perimeter of the central seat base portion and extending from the central seat base portion;

each of the plurality of moldable fingers comprising a distal support zone, a moderate support zone and a severe support zone and wherein each individual moldable finger is adjustably positionable within each of the distal support zone, the moderate support zone and the severe support zone.

11. The moldable seat base of claim 10 wherein the distal support zone comprises two independently moldable fingers to accommodate fine adjustment.

12. The moldable seat base of claim 10 wherein the each moldable finger has a thickness and a length and the thickness of each moldable finger tapers down along the length of the moldable finger.

13. The moldable seat base of claim 10 wherein the thickness of each moldable finger tapers down along the length of the moldable finger in steps from the severe support zone to the moderate support zone and from the moderate support zone to the distal support zone.

14. The moldable seat base of claim 10 wherein the central seat base portion is moldable.

15. A moldable seat base comprising:

a central seat base portion comprising a front seat base portion, a perimeter and a coccyx cutout section opposite the front seat base portion;

a plurality of individually positionable fingers being attached at intervals along the perimeter of the central seat base portion and extending from the central seat base portion;

each of the plurality of positionable fingers comprising a length and a width and comprising a distal support zone, a moderate support zone and a severe support zone, the thickness of each moldable finger tapering down along the length of the moldable finger in steps from the severe support zone to the moderate support zone and from the moderate support zone to the distal support zone, each of the individually positionable fingers being adjustably positionable within each of the distal support zone, the moderate support zone and the severe support zone.

16. The moldable seat base of claim 15 wherein the distal support zone comprises two independently positionable fingers to accommodate fine adjustment of the distal fingers.

17. The moldable seat base of claim 15 wherein the central seat base portion is moldable.

18. A moldable backrest comprising:

a center backrest portion comprising a head support portion and a lumbar support portion and a pair of side portions;

a plurality of moldable fingers attached at intervals along the side portions of the center backrest portion.

19. The moldable backrest of claim 18 wherein each of the plurality of moldable fingers are independently adjustable.

20. The moldable backrest of claim 18 wherein each of the plurality of moldable fingers comprises a distal support zone, a moderate support zone and a severe support zone, each of the plurality of moldable fingers being indepently adjustable with said distal support zone, moderate support zone and severe support zone.

21. The moldable backrest of claim 18 wherein the distal support zone comprises two independently moldable fingers to accommodate fine adjustment.

22. The moldable backrest of claim 18 wherein the each moldable finger has a length and a thickness and the thickness of each moldable finger tapers down along the length of the moldable finger.

23. The moldable backrest of claim 18 wherein the each moldable finger has a thickness and a length and the thickness of each moldable finger tapers down along the length of the moldable finger in steps from the severe support zone to the moderate support zone and from the moderate support zone to the distal support zone.
