Abstract
A height adjustment mechanism for a table top generally comprises two leg assemblies each having a base and two vertical columns, a slidable post assembly on each leg assembly with the slidable post, assemblies supporting the table top, and a drive for raising and lowering the leg assemblies and supported table top. The slidable post assemblies have opposed covers which frictionally engage the vertical posts to hold the table top at an adjusted height. The drive is a lack screw and jack nut in each leg/slidable post assembly, wherein the jack screws are connected by a chain and sprocket drive and are driven by a crank.
