Abstract: Furniture element forming convertible desk and bed This furniture element comprises a frame to which is linked a desk by link means in the form of a deformable parallelogram and arranged to keep the desk horizontal during its movement between its positions of use and non-use, a bed that moves rotation-wise about a horizontal pin between a vertical position of non-use and a horizontal position of use, and transmission means arranged to move the bed from its position of use to its position of non-use while the desk is being moved from its position of non-use to its position of use, and vice versa. The swivel pin of the bed moves vertically translation-wise relative to the frame of the furniture element between a bottom position close to the floor when the bed is in the position of non-use and a top position away from the floor when the bed is in the position of use.
