A drawer system includes a primary drawer and a concealed drawer. The concealed drawer is concealed in a space under the floor of the primary drawer, between the lower portions of the sidewall of primary drawer. The primary drawer moves with the concealed drawer in a locked state to maintain the concealed drawer in the concealed state, and the concealed drawer moves independently from the primary drawer in the unlocked state to allow the concealed drawer to extend from the primary drawer, thereby allowing access to the concealed drawer.

A drawer cabinet has an adjustable drawer assembly mode. The drawer cabinet includes a cabinet body (10) and at least one drawer unit (20). The cabinet body (10) includes a rectangular receiving space (11) and at least one opening (12) in communication with the receiving space (11). Each of four corners of the receiving space (11) is combined with a slide rail (30). Each of the slide rails (30) includes a sliding channel (32) that faces the receiving space (11) and section shapes of which are symmetrical relative to an angular bisector. The drawer unit (20) is slidably combined with the receiving space (11), and an upper edge or a lower edge of two sides of the drawer unit (20) is at least provided with a pair of connection units (40). Each of the connection units (40) is slidably combined with the corresponding slide rail (30) and is provided with a sliding rod (41) that matches the sliding channel (32). The four corners of the receiving space (11) of the cabinet body (10) are provided with the slide rails (30) without assembly direction limitations, so that the assembly directions and the assembly quantity of the drawers are not limited, and so that the flexibility and the variability of arranging drawers in the drawer cabinet are effectively improved.

A sliding assembly includes two pull-out guides which can be secured to opposite side walls and each of which includes a stationary guide rail, a middle rail movably mounted on the guide rail, and a running rail movably mounted on the middle rail. A first slidable element is retained on the two running rails of the two pull-out guides, and a second slidable element is retained on the two middle rails of the two pull-out guides. By moving one slidable element, the other slidable element can also be moved.
