Claim 8:
9. A method for modulating a predetermined pressure in a mattress assembly, comprising the steps of:
providing a mattress assembly comprising an external sleep surface and an internal two-dimensional array of vertically oriented bladders, a first inner vertically oriented spring within each of the vertically oriented bladders, a second outer vertically oriented spring provided within each of the vertically oriented bladders separate of the first inner vertically oriented spring, said second outer vertically oriented spring having a shorter height than said first inner vertically oriented spring, and said second outer vertically oriented spring varying in diameter from larger diameters at upper and lower ends to a smaller diameter between the upper and lower ends;
detecting a pressure level in each of said vertically oriented bladders;
providing a controller that is operably connected to the array of vertically oriented bladders, wherein the controller stores and receives a selection of one or more routines directed to a selected timing for inflating and deflating one or more bladders in the array of vertically oriented bladders; and
using the controller to apply one more of the one or more routines to the array of vertically oriented bladders in order to adjust said pressure level in at least one bladder in the array of vertically oriented bladders.
