The invention discloses a honeycomb foam structure seat. Seat foam stuffed in each of a seat cushion and a seat backrest adopts a honeycomb foam structure. The honeycomb foam structure is formed by arraying a plurality of hollow hexagonal columns, and the hollow hexagonal columns are parallel to each other and hung in a space; the honeycomb foam structure stuffed in the seat cushion comprises a first cushion foam structure and a second cushion foam structure, and the foam density of the first cushion foam structure is larger than that of the second cushion foam structure; the honeycomb foam structure stuffed in the seat backrest comprises a first backrest foam structure, a second backrest foam structure and a third backrest foam structure; the foam density of the third backrest foam structure is larger than that of the first backrest foam structure, and the foam density of the first backrest foam structure is larger than that of the second backrest foam structure. According to the honeycomb foam structure seat disclosed by the invention, the characteristic of body pressure distribution of passengers is taken into consideration, and the deforming characteristic of foam materials is sufficiently applied; besides, the air permeability of foam can be improved.
