2. The adjustable mattress according to claim 1 , wherein the at least one edge portion is a side edge portion and wherein the extension portion is movable relative to the body portion to vary a width dimension of the patient-supporting surface.
3. The adjustable mattress according to claim 1 , wherein the at least one edge portion is an end edge portion and wherein the extension portion is movable relative to the body portion to vary a length dimension of the patient-supporting surface.
4. The adjustable mattress according to claim 1 , wherein the first and second pluralities of fingers are movable between a plurality of incremental inter-fit engagement positions to define a plurality of incremental dimensions of the patient-supporting surface.
5. The adjustable mattress according to claim 1 , further comprising an outer cover configured to enclose the body portion and extension portion.
6. The adjustable mattress according to claim 5 , wherein the outer cover is expandable between at least two sizes for accommodating different dimensions of the patient-supporting surface.
7. The adjustable mattress according to claim 1 , wherein at least one of the body portion and the extension portion is formed from a resiliently compressible material or resiliently compressible materials.
8. An adjustable mattress expandable in at least one dimension, the adjustable mattress comprising:
an inner member, including:
a body portion including a first plurality of spaced-apart fingers extending therefrom; and
an extension portion including a second plurality of spaced-apart fingers extending therefrom, the first and second pluralities of fingers defining complementary configurations configured for inter-fit engagement with one another wherein one of the first and second pluralities of fingers define concavely scalloped configurations and wherein the other of the first and second pluralities of fingers define convexly scalloped configurations, the body portion and the extension portion cooperating to define a patient-supporting surface, the extension portion movable relative to the body portion to vary a degree of inter-fit engagement of the fingers between a first position, wherein the patient-supporting surface defines a first dimension, and a second position, wherein the patient-supporting surface defines a second dimension; and
an outer cover configured to enclose the inner member, the outer cover expandable between a first size and a second size to accommodate the first and second dimensions, respectively, of the patient-supporting surface.
9. The adjustable mattress according to claim 8 , wherein the inner member is expandable in at least one of a width dimension and a length dimension of the patient-supporting surface.
10. The adjustable mattress according to claim 8 , wherein the first and second pluralities of fingers are movable between a plurality of incremental inter-fit engagement positions to define a plurality of incremental dimensions of the patient-supporting surface.
11. The adjustable mattress according to claim 8 , wherein the outer cover includes a main body portion and an auxiliary portion, the auxiliary portion movable from a contracted configuration to an extended configuration to expand the outer cover from the first size to the second size.
12. An adjustable mattress expandable in at least one dimension, the adjustable mattress comprising:
a body portion including a first plurality of spaced-apart fingers extending outwardly from at least one edge portion thereof; and
an extension portion including a second plurality of spaced-apart fingers extending outwardly therefrom, the first and second pluralities of fingers defining complementary configurations and configured for inter-fit engagement with one another, wherein one of the first and second pluralities of fingers define concavely scalloped configurations and wherein the other of the first and second pluralities of fingers define convexly scalloped configurations, the body portion and the extension portion cooperating to define a patient-supporting surface, the extension portion movable relative to the body portion to vary a degree of inter-fit engagement of the fingers between a first position, wherein the patient-supporting surface defines a first dimension, and a second position, wherein the patient-supporting surface defines a second dimension.
13. The adjustable mattress according to claim 12 , wherein the extension portion is movable relative to the body portion to vary a width dimension of the patient-supporting surface.
14. The adjustable mattress according to claim 12 , wherein the extension portion is movable relative to the body portion to vary a length dimension of the patient-supporting surface.
15. The adjustable mattress according to claim 12 , wherein the first and second pluralities of fingers are movable between a plurality of incremental inter-fit engagement positions to define a plurality of incremental dimensions of the patient-supporting surface.
16. The adjustable mattress according to claim 12 , wherein at least one of the body portion and the extension portion is formed from a resiliently compressible material or resiliently compressible materials.
