A convertible seat that has both a seat and bed position. The convertible seat includes a stationary bed section and folding bed section that pivots relative to the stationary bed section. The folding bed section serves as the seating surface when the seat is in the seat position and the foot end of the bed when the seat is in the bed position. An air mattress is located between the stationary bed section and folding bed section when the seat is in the seat position. Inflation of the air mattress causes the folding bed section to pivot outward to create the bed position.
