Tablet side arm assembly for mounting on a chair, in which a side arm positionable at the side of a chair is arranged for stably pivotally connecting thereto a floating tablet, e.g. having a planar writing or working surface thereon, on a pivot axis situated with respect to the side arm for displacing the tablet along a rotational movement path sequentially forwardly and outwardly and thence downwardly and backwardly relative to the horizontal from a substantially horizontal working position extending generally crosswise of the side arm to a substantially vertical storage position extending generally laterally of the side arm, such as by providing an angular offset portion on the side arm extending in an offset plane at an angle, e.g. of about 45 degrees, to the horizontal to which an angle bracket carrying the tablet is pivotally connected via a pivot pin extending along the pivot axis, and also preferably extending normal to the offset plane and within a substantially vertical transverse plane arranged substantially parallel to the corresponding chair back portion, and optionally including stops limiting pivotal movement of the tablet to an arc, e.g. of about 180 degrees, corresponding to the extent of the rotational movement path between the working and storage positions.
