ABSTRACT:
A writing table includes a writing surface countersunk into a working plate. Continuous adjustment of the inclination of the working surface towards a user from being coplanar with the working plate to a maximum angle is achieved through provision of a roller situated beneath a rear portion of the working surface. An adjustable footrest for the writing table that can be manipulated by a user's foot comprises a further roller, the ends of which are supported by left and right profile members having a desired adjustment profile.
