A furniture system includes a base, a first linkage and a second linkage. The base is configured to be disposed on a flat surface and to be connected to an article of furniture. The first linkage is connected to the base and configured to be connected to the article of furniture. The first linkage is configured to be actuated to cause the article of furniture to translate relative to the base. The second linkage is connected to the first linkage. The second linkage is biased into a locked state in which the second linkage prevents movement of the first linkage. The second linkage is configured to be actuated by an applied force into an unlocked state in which the second linkage allows movement of the first linkage (and the article of furniture to which the first linkage is configured to be connected).
