Follow common-sense principles of caring for your chairs beginning immediately after you receive your new chair.    The first rules to observe are the following:    Do not use harsh chemicals, solvents, or chemical wipes to clean your college chairs.   Wipe the wood surface with a soft, damp cloth, and use a soft, dry cloth to dry.  Maintain moderate temperatures, and avoid direct sunlight.  Keep your shipping carton in case you move.   Avoid extremes, and exercise common sense.
