- the leg rest is articulated pivotably on the seat structure.
- the leg rest is articulated pivotably about an axis arranged at a front end of the seat surface.
- pivoting takes place by means of a folding mechanism with a stopper element projecting downwards from the seat surface, which holds the leg rest against the force of gravity in a lying position in a lying position of the seat structure in a use position.
- the legrest is slidably mounted and hinged in a drawer.
- the leg rest is loaded by means of a constraining force, which causes it to fold down when the leg rest is pulled out of the drawer.

- an adjusting movement between the working position and the lying position is done manually.
- a user can be supported for this purpose, for example, on the armrests and initiate a pivoting movement in the reclining position by leaning back.
- the pivoting mechanism comprises a drive or a plurality of drives. The drives are suitably selected according to the pivoting mechanism.
- a timer with a wake-up function is provided, wherein after a defined period of time a user is woken up.
- a constraining force is applied, by means of which a provision of the seat structure 3 from the lying position takes place in the working position.
- the coercive force is applied in a development by a drive, in another embodiment by means of a spring, which is released after the expiration of the period of time.
