An adjustable assembly with at least a pair of adjustable legs is used to stabilize a support element on a wide range of terrains. Each of the adjustable legs is engaged with a leg exchange bracket 13 that is adapted for and connected to a support element such as a sawhorse beam, a tabletop, or other leg-bearing support element. Each of the adjustable legs can be variably adjusted to adapt to height and other terrain surface variations so as to provide an essentially steady and generally level support surface. Once the desired adjustment is selected, the legs are locked. If the terrain changes or there is a need to transfer the support surface to another terrain, the legs can be readily unlocked, the position of one or more legs adjusted, and the lock(s) re-engaged to provide a steady and generally level assembly on the changed terrain. The assembly can also be configured so that it can be reversibly engaged with a variety of work surfaces either by removal of the full assembly from the support surface, or removal of the legs from their respective leg exchange brackets. An assembly can be readily disengaged from a first support surface, and reengaged with a second support surface. The legs of the assembly are easily adjusted to allow for stacking and for ease of transport of the support surface.
