Abstract
A furniture article, such as a telescopingly adjustable column for chair height adjustment or an adjustable table leg, includes a tubular first member and a tubular second member telescopingly and rotatably supported by the first member. A sleeve-like bearing is positioned between the first and second members. The bearing has an original pre-cured shape that fits loosely into the clearance space between the members during assembly, and further has lubricious bearing material to facilitate smooth extension of the members, but further is made at least in part of a material that when cured expands to a size and shape that takes up an increased percentage of the clearance space. By this arrangement, the bearing can be easily positioned in the clearance space, but after thermal curing the bearing expands to reduce wobbling and looseness between the first and second members.
