A cabinet assembly includes a base and walls secured to the base to define an interior. The cabinet assembly further includes a pivot pin coupled to the base and a locking device coupled to the base. The locking device is movable relative to the base between an engaged position and a released position. The cabinet assembly additionally includes a support foot. The support foot is fixed to the base in a first orientation when the locking device is in the engaged position. The support foot is movable about the pivot pin to a second orientation spaced from the locking device when the locking device is in the released position.

A hydraulic buffering leg cushion is mounted to a supporting platform. The hydraulic buffering leg cushion includes a leg cushion body, a movable unit, and a fixed connecting member. The leg cushion body is provided with a leg cushion accommodating space, and includes an upper cover, and a lower cover. The movable unit is received in the leg cushion accommodating space, and includes a piston, a membrane assembly, a rubber bowl, and a movable portion. The rubber bowl is clamped, at its outer circumference, by and between the upper cover and the lower cover, so as to partition a damping accommodating space for receiving damping oil. The movable portion and the rubber bowl are pressed, in sequence, onto the piston. The piston is provided with a damping channel, and is connected with the lower cover through a restoring spring. The membrane assembly is disposed underneath the piston, and forms, with the piston, a one-way valve structure. The restoring spring passes through the membrane assembly. The fixed connecting member is fixedly arranged on the movable portion of the movable unit. As such, by using the supporting force of the restoring spring and the damping oil in the damping accommodating space for providing with buffering hydraulic pressure, a balance for the supporting platform can be adjusted automatically to a balance within an effective range for the supporting platform, without the need of a manual adjustment for a balance. This will ensure stability of the supporting platform without shaking easily.

A method of assembling a shelf system is provided. The method includes placing a foot sleeve around a bottom portion of a side support panel. The foot sleeve includes a first sidewall configured to extend alongside an outer face of the side support panel, a second sidewall configured to extend alongside an inner face of the side support panel that faces opposite the outer face and an end wall configured to extend along a front face of the side support panel, the end wall connecting the first and second sidewalls. The first and second sidewalls and end wall define a volume that is sized to receive the side support panel. The side support panel is mounted to a wall such that the side support panel extends in a vertical direction and is perpendicular to the wall. The foot sleeve is slid toward a floor beneath the side support panel to fill a gap between the side support panel and the floor after mounting the side support panel to the wall.
