A lightweight reinforced seat assembly for a transportation vehicle is disclosed which includes a molded seat shell having a shell exterior and a shell interior. The seat shell includes a seat section and a back section joined together by a generally curved section. A plurality of seats is formed in the seat shell. A reinforcing network of longitudinal and lateral, generally enclosed tubular rib elements reinforce the seat shell to eliminate metal framing and weight. The reinforcing rib network includes a front tubular rib element extending laterally across a front width of the seat section, and a top tubular rib element extending laterally across a top width of the back section. Longitudinal edge tubular rib elements extend on opposing edges of the seat shell generally through the seat-section, curved section, and back-section. The edge tubular rib elements are connected to the front and top tubular rib elements. An intermediate tubular rib element extends between adjacent ones of the plurality of seats connected to the front and top tubular rib elements.
