1. A furniture element, comprising:
at least one storage level;
a body; and
a bottom plate,
wherein mutually facing bearing surfaces of the body and of the bottom plate each have at least one raceway in which rolling elements are guided,
wherein the body is movable relative to the bottom plate from an initial position to an intermediate position and further to an open position and back,
wherein, in the intermediate position, the body is rotated relative to the bottom plate in a direction of rotation and displaced in a predetermined direction,
wherein the at least one raceway of the bottom plate is formed mirror-symmetrically with respect to an axis of symmetry extending at an oblique angle relative to a side edge of the bottom plate,
wherein the body has a bearing plate on a side facing the bottom plate, wherein the at least one raceway of the body is at least one raceway of the bearing plate that is integrally formed in a side of the bearing plate facing the bottom plate, and wherein the at least one raceway of the bearing plate is formed mirror-symmetrically with respect to an axis of symmetry extending at an oblique angle relative to a side edge of the bearing plate,
wherein the bottom plate, the bearing plate, the rolling elements, and a rolling element cage, in which the rolling elements are accommodated in a captive manner, form a translational-rotational bearing, and
wherein the rolling elements are arranged on at least two circles, wherein axes of symmetry of the rolling element arrangement on a first one of the two circles are inclined by 45° to the axes of symmetry of the rolling element arrangement on a second one of the two circles.
