The invention relates to a corner cupboard (1) for placing in the corner of a room, said corner cupboard comprising two assembly units (E1, E2) which are adjacently arranged in a section (la) of the corner cupboard, can be horizontally displaced by means of guides (3, 4, 15, 16), and are interconnected in a mobile manner by means of coupling elements (6, 7, 8) in such a way that if the first assembly unit (E1) fixed to a sliding and pivoting guide (3, 4) is horizontally displaced (pulled out or pushed in) and pivoted about a vertical axis (10) by approximately 90 DEG , the second assembly unit (E2) is displaced, by means of a displacement guide (15, 16), towards the position freed by the first assembly unit (E1) or away from the same. The displacement guide of the second assembly unit (E2) consists of two guiding rails (15, 16) which are horizontally superimposed and vertically staggered, and extend over the length of the section (la) of the corner cupboard, said guiding rails being fixed to the bottom of the cupboard (1b) by means of two triangular support plates (17).
