A portable desk adapted for use in temporary work areas such as a seat in a vehicle includes a main body having a work surface member at a position spaced from a support surface, a first support member adapted to receive a laptop or portable computer mounted on the work surface member for access by the vehicle driver when the portable desk is mounted in the front passenger seat of the vehicle, and a second support member adapted to receive a computer peripheral device, such as a printer, also for access to by the vehicle driver. Preferably, the work surface member is at the top surface of the portable desk, and the first support member may be adjustably positioned between a first position adjacent a driver of the vehicle and a second position spaced away from the vehicle driver.
