WHAT IS CLAIMED IS:

1. Apparatus for controlling massage intensity in a massage device, the apparatus comprising:
an airtight bladder forming a cavity therein;
a foam core having a default thickness located within the cavity;
an air inlet to the bladder; and
a pump operatively coupled to the inlet for varying the amount of air in the cavity,
wherein the bladder compresses the foam from its default thickness when air is removed from the cavity.

2. The apparatus of claim 1, wherein the pump includes a vacuum reservoir and evacuates air from the cavity to compress the bladder.

3. The apparatus of claim 1, wherein the default position of the bladder is in an expanded state.

4. The apparatus of claim 1, wherein the default position of the bladder is in a deflated state, and the bladder is inflated by adding air to the cavity.

5. The apparatus of claim 1, wherein the bladder includes neoprene.

6. The apparatus of claim 1, wherein the foam core includes polyurethane.

7. The apparatus of claim 1, further comprising a controllable valve for controlling air into and out of the cavity.

8. The apparatus of claim 7, further comprising a controller for automatically adjusting air into and out of the cavity as part of a massage program.

9. The apparatus of claim 1, further comprising a massage mechanism disposed proximate the bladder, wherein the amount of air within the cavity determines the massage intensity.

10. The apparatus of claim 9, wherein the bladder comprises a plurality of massage bladders, and the air in the cavity of each bladder is independently controllable.

11. The apparatus of claim 1, wherein the massage device comprises a massage chair.

12. A massage device comprising:
a massage mechanism;
one or more bladders disposed proximate the massage mechanism, wherein the bladder comprises a cavity;
one or more controllable valves for controlling amount of air within the cavity;
wherein the air within the cavity may be varied to alter volume of the bladder, thereby affecting intensity of massage felt by a user sitting in the massage chair.

13. The massage device of claim 12 further including an active pump coupled to the bladder for adding air into the cavity.

14. the massage device of claim 13, wherein the bladder is made of neoprene.

15. The massage device of claim 12, wherein one or more of the bladders include foam housed within the cavity of the bladder.

16. The massage device of claim 15, wherein the foam is made of polyurethane.

17. The massage device of claim 15, further comprising:
an air inlet to the bladder;
a pump operatively couple to the inlet for varying the amount of air in the cavity;
wherein the foam core has a default thickness and the bladder compresses the foam from its default thickness when air is removed from the cavity.

18. The massage device of claim 17, wherein the massage device is a chair.

19. The massage device of claim 17, wherein the pump includes a vacuum reservoir.

20. The massage device of claim 12, further comprising a frame for housing the massage mechanism, and an overlay containing the bladders for adjusting the massage intensity.
