PROBLEM TO BE SOLVED: To solve problems that it is difficult to use a side cushion element as a seat back and a usable horizontal width of the seat back becomes narrow because a step is formed between center cushion elements at the time of reclining. SOLUTION: Step parts 22 are formed on a side face cs of a center cushion body 20ac of a cushion body 20a of a seat back for a two-people seat, and a side face ss of an opposed side cushion body 20as. An upper half uh of the center cushion body is formed into a wider shape than a lower half Lh by the step parts. Even when a step is provided between two cushion elements 20ac and 20as at the time of reclining, a width enlarged portion (Δw) of the upper half of the center cushion element can be utilized as a seat back 12, to secure a large horizontal width usable as a seat back at the time of reclining.
