Due to the fact that in an item of furniture having four legs, in particular a table, two legs (5, 5') are provided at the bottom with communicating units (1, 2 and 1', 2' respectively) which produce a pressure compensation between the forces (P, P') acting on the legs (5, 5') in that the loaded unit (1, 2) moves in the direction of the loaded table leg (5) whereas the other unit (1', 2') moves in the opposite direction away from the table leg (5') towards the floor (6'), the furniture can be set up with all its four legs securely and without wobbling even on an uneven floor. <IMAGE>
