Abstract

A pair of stackable, nestable blocks for elevating the leg of a bed to a plurality of selectable heights employs first and second blocks that each have upper and lower ends, with recesses being provided in at least one of the ends of each block that can be oriented upwardly to receive and support the foot or lower end region of a bed leg. Each block has a different length, which enables each block, used separately, to support the bed leg at a different height. Recesses of differing depths preferably are provided in opposite ends of at least one of the blocks, whereby the block or blocks that have dual-depth recesses can be inverted to provide bed leg support at two different heights. One of the two blocks preferably has a larger size than the other and is provided with recess(es) large enough to receive and support one or both of the end regions of the other of the blocks, whereby the smaller-size block can be stacked and nested atop the larger-size block to provide still more bed leg elevation heights. Five heights may be provided utilizing two blocks of different length and size if only one of the blocks is provided with different depth recesses. Additional bed leg elevation heights may be provided if both blocks have different depth recesses in their opposite ends.
