• a plurality of rigid panel sections configured to cover the at least a portion of the cargo bed, at least one of the plurality of rigid panel sections comprising:
• a rigid panel having a first face, a second face opposite the first face, and an edge therebetween, the first face having a first margin adjacent the edge, the second face having a second margin adjacent the edge;
• a first frame member disposed along at least a portion of the edge and having a first flange overlying the first margin;
• a second frame member distinct from the first frame member, the second frame member being disposed along at least a portion of the edge and having a second flange overlying the second margin, and
• a coupling mechanism connecting the second frame member and the first frame member outboard the edge.

A method of assembling a tonneau cover, the method comprising:

• providing a rigid panel having a first face, a second face opposite the first face, and an edge therebetween, the second face having a second margin adjacent the edge, the first face having a first margin adjacent the edge;
• disposing a first frame member along at least a portion of the edge of the rigid panel such that a first flange of the first frame member is overlying the first margin;
• disposing a second frame member, distinct from the first frame member, along at least a portion of the edge of the rigid panel such that a second flange of the second frame member is overlying the second margin, and
• coupling the first frame member and the second frame member together outboard the edge of the rigid panel.
