Operating Instructions
Reclining Function
The left and right seats of the 4-seater sofa, as well as both single recliner chairs, feature a manual reclining function. To recline, simply pull the round pull ring located inside the seat. The footrest will extend, and the backrest will adjust to your desired angle. The middle two seats of the 4-seater sofa do not have a reclining or open footrest function.
