How Should I Store Antique Furniture?
From my personal experience I would suggest finding another place to store it. The big issue is excess humidity that will soften the glue especially on the older pieces. Veneers will start to lift and mold will grow. If you must store it in the basement run a dehumidifier year round, in the winter it most likely won't run often. In the summer it will likely run continuously. Unless you have a wood stove in the basement or live in a very dry area lack of humidity shouldn't be an issue.
