Your upholstered furniture may be equipped with a long chair that can be folded by 90° manually:
to do this, grip the external end of the long chair with both hands under the base of the seat and lift it up slightly. You will immediately notice the seat detaching from its secure position. Then turn it gently, until it protrudes from the back upholstery by 90°. When the seat is turned, a support leg automatically unfolds. This function’s folding seat is only approved and functional up to a maximum load of 110kg.
