Abstract
An apparatus for supporting a work surface, such as a drafting table, that requires both vertical adjustability and a great degree of stability once the desired elevation is achieved. Interposed between two telescoping column members are a series of spring-connected wheel assemblies that cooperate to apply a holding force to the base column member in order to maintain the extendable column member at its desired attitude of elevation.
