A compact front adjustment system for leveling feet for furniture (M) with a bottom (12) and shoulders (11), comprising: at least two front feet, a right foot (13d) and a left foot (13s) and at least two rear feet, a right foot (14d) and a left foot (14s), wherein each of said rear feet (14d,14s) comprises an adjustment mechanism in height, which is accessible from outside the foot through respective holes (21d,21s) and which can be maneuvered by means of a maneuvering tool (18). According to the invention, a respective supporting and guiding unit (17d,17s; 22; 25) for said maneuvering tool (18) is provided in combination with said rear feet (14d,14s), said unit being assembled on said bottom (12) of the furniture (M) in an intermediate position between said front feet (13d,13s) according to an axis X which is aligned with said holes (21d,21s) for access to the adjustment mechanism in height of the respective rear foot (14d,14s).

A machine foot with a built-in load cell is provided, the load cell being suspended in an overlying sheath, with the feature that the screws which hold the load cell in place in the lower part of the machine foot pass through a bottom plate and are screwed up into a fastening ring that is separate from the sheath material. A method of production of a machine foot is provided, by which a rubber resin is moulded down into the sheath of the machine foot and is vulcanized thereto, the fastening ring being embedded in the rubber resin in an area that abuts the lower side of the sheath.

A kit may include at least one frame lifting mechanism configured to be mounted within the support frame. The lifting mechanism may include a movable element configured to be movably mounted to the frame and an extendible member configured to extend between the movable element and a static member mounted on the frame. The movable element includes at least one support portion extending from a lower surface of the movable element when the movable element is mounted to the frame. The extendible member is configured to be movable between a compressed state and an extended state. The movable element is configured to be mounted to the frame such that on extension of the extendible member the movable element is pushed downwards and the at least one support portion moves below a base of the frame and provides a lifting force to the frame.

A carrier plate with rollable balls therein comprises a plate body including an upper plate and a lower plate; the lower plate being fixed to a lower side of the upper plate; the upper plate and lower plate having a plurality of through holes which are positioned corresponding to the through holes of the upper plate; a plurality of balls loosely embedded into the through holes of the upper plate and the lower plate. A diameter of the ball is larger than the summation of widths of the upper plate and lower plate, and the balls protrude from an upper side of the upper plate and a lower side of the lower plate.
