The counterbalancing elements comprise at least one leaf spring forming a bow inserted between the table top and a counter abutment below the table top so that the leaf spring or springs is biassed to form said bow, whereby the load on the bow has a tendency to cause a lateral flexure of the bow. The arrangement is such, that the downwardly directed force component caused by the weight of the table top and the pressure exerted by the bent leaf spring or springs, are directed opposite to each other.
