Turn the chair over on a work surface or on top of an old towel placed on a counter or the floor.
Inspect the chair for any loose legs, dowels or other pieces securing the chair together. Wiggle each part of the chair to see if any part is loose.
Tighten any loose parts with the appropriate screwdriver or push the piece back in until it is securely tightened.
Squeeze the wood swelling solution evenly around each piece where it connects into another piece. Apply the solution around where any dowels connect with the legs, where any dowels connect into the base or where the legs connect into the base.
Let the chair sit for at least one hour to allow the solution to dry.
