Remove any loose cushions or pads from the furniture, and then gently push against it to help determine the source of the squeak. Listen carefully so you can tell what side of the furniture the squeak is located on.
Disassemble the furniture where the squeak is located using a screwdriver. Because the squeaks are often caused by two pieces rubbing together, the glue between the two components has failed or a screw has loosened itself up. If the furniture is a recliner on which the metal supports are squeaking, simply apply dry graphite lubricant to each of the pivot points. This will silence any squeaks from metal on metal contact.
Apply beeswax to any screws that hold two pieces of wood together that are squeaking. Beeswax will hold the screw in place so that it cannot back itself out of the mounting hole as easily, and will help lubricate the wood and the metal both so the squeak will not come from a wood on metal contact.
Glue loose dowel pins back in place using wood glue. You can also use wood glue between two pieces of wood that are connected with a screw. Allow the glue to set overnight before using the furniture or replacing the cushions.
