Disclosed is an intuitively operable rotation mechanism for a flip top table that includes an offsetting feature that provides aligned table legs when the table is in a use configuration while offsetting the legs when they are in a storage configuration. By offsetting the table legs in storage configuration, the height of the table legs can be more than one half of the length of the table. This feature is of particular importance for folding tables that are positioned at a standing height.
