The table consists of a top on a base (2) and four legs with fixed upper (4) and hinged lower (3) sections. The hinged ends (5) of the leg sections are stepped to limit their deployment, and the lower sections are stabilized in the deployed and retracted positions by a bar (9) with notches (10). The bar is attached to a pivoted cross-member (6) at one end and the notches engage with a fixed cross-member (8) at the other.
