  • the document EP 1 434 507 discloses a furniture element comprising a frame on which is pivotally mounted a bed about a horizontal axis secured to the bed between a vertical non-use position and a horizontal use position.
  • the furniture element comprises a desk connected to the frame of the latter and to the bed by deformable parallelogram shaped connecting means and arranged to maintain the horizontal desk during its movement between a horizontal position of use away from the ground and a position of no horizontal use near the ground.
  • the furniture element further comprises transmission means arranged to move the bed from its use position to its non-use position during the movement of the office from its non-use position to its use position and vice versa.
  • the item of furniture described in this document provides a substantially horizontal movement of the office between its positions of use and non-use.
  • the elements resting on the latter remain substantially stable and are therefore unlikely to fall on the ground or overturn.
  • the conversion of the furniture item into a bed or an office is simplified.
  • the fact that the bed is pivotally mounted on the frame of the furniture element has the consequence that in the non-use position, the bed is away from the ground. This results in a significant height of the height of the furniture element in the use position of the office.
