In most cases a pool table has to be taken apart in order to move. The sheer weight of the pool table can cause major damge to the frame and/or pool table slate if moved with out being disassembled. Most residential pool tables are made with 3 pieces of slate as a table top, the slate is screwed down the to the frame of the pool table. It is very likely to damage and crack the slate when moving in one piece. The only exception is the one piece slate pool table which is usually only used in commercial type pool tables that are coin operated and have an automatic ball return system.
