Seat assemblies are provided which include a seat base structure, a seat cushion supported by the seat base structure and at least a lateral outboard seat lip positioned relative to the seat cushion so as to assist a passenger during seat entry and exit. The lateral outboard seat lip is preferably attached relative to the seat cushion for manual movements between an extended position wherein the outboard seat lip extends outwardly thereby increasing effective surface area of the seat cushion and a deflected position wherein the outboard seat lip extends upwardly or downwardly relative to the seat cushion so as to thereby decrease the effective surface area of the seat cushion.
