1. A glass-bending tooling for bending glass in a direction, comprising:
a contoured tooling rail;
an edge-press molding element, wherein the edge-press molding element circumferentially follows a form factor, wherein the form factor comprises a thickness measured in the direction and a width being measured perpendicular to the direction, wherein the width is greater than the thickness, wherein the width of the edge-press molding element is greater than a width of the contoured tooling rail measured perpendicular to the direction; and
a cushion layer on a contact surface of the edge-press molding element, wherein the edge-press molding element is configured to press the contoured tooling rail via its own self weight, wherein edge-press molding element comprises a body of material that extends inward from a periphery thereof by the width.
