Abstract: Disclosed herein is a reducible volume desk, or in other words, a desk whose volume can be reduced with the utmost ease so that, at the time it is being transported, it takes up the least possible space. Subsequently, in an extremely short period of time, the desk can be reassembled in its final configuration with the certainty that all of its component parts are available.The desk is essentially composed of a first member, or support platform, to the underneath part of which are connected two second members that define the lateral walls and a third cross member perpendicular thereto; the said second and third members being foldable, one on the other, in parcel form, on the lower surface of the support platform.
