A system is described for lifting tables, chairs, bed bases, children's high chairs or other items to be lifted; which is lockable and unlockable automatically through at least one universal telescopic snap movement or in a known way comprising at least one pantograph—a vertically moveable load-bearing structure arranged between a base and the bottom of a piece of furniture or element to be lifted and a stopping device intended to keep the pantograph in a desired height position. According to the invention the load-bearing structure is formed by at least one pantograph having a plurality of parallelograms articulated to one another whose lower vertex is articulated to the base and upper vertex is articulated to the bottom of the furniture or object to be lifted and the stopping device is an integral part of telescopic snap movement.
