An adjustable support apparatus, for elevating a furniture article, includes a base and a cradle which operatively engages the base so as to be supported thereby. The cradle includes a substantially horizontal support platform adapted to support a portion of a furniture item thereon. One of the base and the cradle has a plurality of projections extending outwardly thereon, and the other of the base and the cradle has a plurality of recesses, which mate with the projections when the base and the cradle are operatively engaged. The base and the cradle are rotatably adjustable relative to one another, to variously engage the projections and recesses and thereby establish multiple different height positions of the cradle support platform. The apparatus is used to adjustably raise the height level of a furniture article, particularly a bed, by placing individual supports according to the invention underneath the respective leg posts of the furniture article.

1. An adjustable support apparatus for use in elevating furniture, the apparatus comprising a base and a cradle which operatively engages the base so as to be supported thereby;one of the base and the cradle having a plurality of projections formed thereon, and the other of the base and the cradle having a plurality of recesses formed in a wall thereof which are configured to mate with the projections on the other of the base or cradle when the base and the cradle are operatively engaged, each of said recesses having a projection-engaging surface, said recesses being arranged such that said projections may be selectively disposed to engage the projection-engaging surfaces of different ones of the recesses depending on an alignment of said cradle and said base relative to each other;wherein said projections are arranged at different elevational levels along an engagement direction of said cradle and said base;wherein said cradle includes a support platform adapted to support a support leg of a furniture item thereon and a circumferential wall extending upwardly from peripheral edges of said support platform that is adapted to prevent said leg from sliding off said support platform;wherein said base and said cradle are rotatably adjustable relative to one another in different alignments, to variously engage the projections and recesses and thereby establish multiple different height positions of the cradle support platform, and in at least one of said different alignments said cradle support platform is disposed at a level significantly below an upper surface of said base.2. The adjustable support apparatus of claim 1, wherein the cradle has a plurality of projections extending outwardly from an outer wall thereof, and the base has a plurality of recesses formed in an inner wall thereof which are configured to mate with the projections on the cradle when the base and the cradle are operatively engaged.3. The support apparatus of claim 1, wherein said support platform and said circumferential wall of said cradle body define a cup-shaped recess.4. The adjustable support apparatus of claim 1, wherein an outer surface of the base is tapered such that a bottom portion of the base is wider than a top portion thereof.5. The support apparatus of claim 1, wherein said base is hollow with a central opening defined therethrough, and said cradle slidably fits in said central opening of the base.6. The support apparatus of claim 1, wherein said support platform and said circumferential wall of said cradle define a cup-shaped recess.7. The support apparatus of claim 1, wherein said support platform extends substantially horizontally when said cradle is operatively engaged to said base.8. The support apparatus of claim 1, wherein the entire cradle is disposed at a level significantly below the upper surface of said base in at least one of said different alignments.9. An adjustable support apparatus for use in elevating furniture, the apparatus comprising a base and a cradle which operatively engages the base so as to be supported thereby;wherein the base comprises a hollow base body having a central opening formed therein to receive the cradle, said central opening defining an inner wall of the base, said inner wall having a plurality of grooves formed therein receiving projections provided on the cradle,the cradle comprises a cradle body having a substantially horizontal support platform extending thereacross and a circumferential wall extending upwardly from peripheral edges of said support platform, the cradle projections extending outwardly from an outer surface of said cradle body, said projections configured to be selectively fitted into different ones of said grooves in said base inner wall depending on an alignment of said cradle and said base relative to each other, to establish different height positions of the support platform; wherein said projections are arranged at different elevational levels along an engagement direction of said cradle and said base;said cradle and said base being moveable relative to each other into different alignments of the cradle on the base to establish the different height positions of the support platform, and in at least one of said different alignments said support platform is disposed at a level significantly below an upper an upper surface of said hollow base body.10. The support apparatus of claim 9, wherein said cradle slidably fits in said central opening of the base, and the entire cradle is disposed at a level significantly below the upper surface of said hollow base body in at least one of said different alignments.11. The support apparatus of claim 9, wherein the grooves of the base are substantially vertically oriented.12. The support apparatus of claim 9, wherein the grooves of the base are substantially horizontally and vertically oriented.13. The support apparatus of claim 9, wherein said cradle body is substantially cylindrical.14. The support apparatus of claim 9, wherein said cradle body is formed in a substantially rectangular box shape.15. The support apparatus of claim 14, wherein said central opening of said base body is a polygon.16. The support apparatus of claim 15, wherein said central opening of said base body is a decahexagon comprising corner portions of two square outlines superimposed at a 45 degree angle.17. The support apparatus of claim 9, wherein the cradle has a plurality of said projections, said projections are vertically and circumferentially spaced-apart.18. The support apparatus of claim 17, wherein the base is adapted to simultaneously support said plurality of vertically and circumferentially spaced-apart projections in said grooves thereof.
