A furniture piece has a worksurface and a support frame having first and second ends. At least two legs extend downwardly from each of the first and second ends for supporting the furniture piece on a floor surface. A linkage couples the support frame to the worksurface. The linkage is configured so that the worksurface can be moved between a first position in which the worksurface is substantially parallel to a horizontal plane defined by the support frame and a second position in which the worksurface is above and at an angle to the horizontal plane.

A smoothly adjustable artboard comprises: a base configured for fixing, an adjusting bracket configured to adjust the height and angle of the artboard, and a painting plate configured to place drawing paper, and the adjusting bracket is arranged between the base and the painting plate, wherein the adjusting bracket includes a connecting seat, a connecting bracket, a force applying mechanism, a cam member, a roller and a one-way limiting mechanism, the roller is rotatably arranged on the connecting bracket and is located at one end close to the base, and one end of the force applying mechanism is connected with the connecting seat, and the other end of the force applying mechanism is connected with the cam member, wherein a curved surface of the cam member is configured to press against the roller under the pushing action of the force applying mechanism.
