If a chair or small table sits unevenly on the floor, determine if the floor is flat by switching it with another piece in a different area. If the wobble moves with the piece, determine the "long" leg. Begin adjustment by placing a small block of wood on the floor under the long leg. Now, lift the chair and firmly bring it down so that long leg contacts the wood. This should adjust the longer leg. If there is serious unevenness that cannot be corrected, contact your local Patriot Dealer or Representative.
