Abstract: A furniture system including at least one worktop which mounts thereon a plurality of legs adjustable in height. The legs are connected to respective support plates recessed in the underside of the worktop. At least one linear guide is recessed into the underside of the worktop for the mounting of accessories on the worktop. A plurality of worktops can be mounted in spaced relation from a support surface by a common leg via support arms. The worktops can be joined together in either a flush arrangement or separated from one another. In the separated configuration, a tray can be fitted in the space between two adjacent worktops for the housing of cables, electrical sockets and the like.

Abstract: A modular unit for assembling seats comprises a plurality of elements which are spatially complementary and can be grouped together about an axis. The elements can be associated with respective portions of the seat to be produced and are rigidly connected together by a screw which can extend through a longitudinal hole formed jointly by grooves in the elements. The rotation of the screw causes a transverse sliding of two locking elements having inclined surfaces which cooperate with respective sloped portions of the elements in order to urge the elements into a state in which they are assembled about the axis. The elements may be of integral construction with portions of the seat such as a seat portion, an armrest portion or a leg portion.
