Wooden chair legs, over time, become susceptible to damage and weakening after years of wear and tear. Excessive leaning, scooting and moving wears down chair legs, causing the rungs to loosen and eventually pop out of their sockets. If you don’t want to resort to having to buy a new set of chairs just to appease the one with a broken leg, consider repairing the chair leg yourself. With the proper materials and supplies, you can put your chair back into good working order within a day.
Place the chair onto a table top at eye level.Use a dead blow hammer to break the joint apart and to gain access to the rung.
Apply a layer of polyurethane glue around the chair rung. Pop the rung into the socket.
