Most ping pong tables fold in half on a wheeled frame or split into two halves, which makes them manageable but bulky. The playing surface scratches and dents easily, so protecting it is the main concern.
Pro tip: Move a folding table with the two halves latched together where the design allows, so it stays one stable unit.
Watch out: Always lock a folding table before moving, since an unlatched half can drop and cause injury.
