Lap-supported devices are provided which are especially adapted for use by seated individuals, and include a base member, an opposed pair of clamp arms extending outwardly from a bottom surface of the base member and spaced apart from one another so as to accommodate therebetween a lap region of an individual, and a biasing assembly which exerts a bias force onto each of the clamp arms and thereby provide a clamping force against the respective lateral thigh regions of an individual. Some embodiments will have pivotal clamp members which include a torosional spring assembly to provide clamping force against the individual's lateral thigh regions. Alternatively or additionally, other embodiments may be provided with slide plates which carry the clamp arms and a tension spring assembly operatively connected to the slide plates.
