After lumber is freshly cut from the log, it is dried before being made into furniture. As it dries, it shrinks and twists unpredictably. If not completely dry before assembly, furniture will warp and joints may spring apart.This is especially a problem for mantels exposed to the drying heat of a fire. Mantels constructed in a dry climate have an advantage since lumber is often drier during construction and less likely to dry any further. All wood furniture can absorb moisture from the environment causing minor swelling.
