A support assembly for a table being mounted on a first wall includes a frame configured to be at least partially inserted in a cavity defined in a second wall. The table is movable between a stowed position and a deployed position. The support assembly includes at least one support arm rotatably coupled to the frame and movable through a plurality of positions between a retracted position and an extended position. A biasing member is operatively connected to the frame and configured to bias the support arm toward the retracted position, wherein the at least one support arm is configured to move from the retracted position to the extended position as the table moves from the stowed position to the deployed position. A method for assembling a table system and a table system having the support assembly are provided.
