Your upholstered furniture is optionally equipped with a manual headrest adjustment. The inclination of the headboard is included and can be folded up or down steplessly:
To adjust the headboard, grab it with both hands and pull it forward towards you. It locks in the position you let go. The headboard CANNOT be pushed back halfway! Always pull them all the way forward first. Only then does the built-in lock release and you can push the headboard backwards.
⇒ We have put together instructions on how to operate the electric headrest adjustment here for you.
