A seat comprises a cushion, a pair of backrests, a pair of bolsters, and a pair of armrest pads. The cushion has a width of double seat. Both the bolster and the backrest have a width of single seat. A front face of the bolster has a concave arc portion, and a back face thereof has a slanting arc portion. The bolsters can be turned 180 degrees. A fixing device joins the bolster and the backrest. A joining device is disposed at the adjoining position of the two backrests. An armrest is joined at each side of the cushion. A pad is joined on the armrest to form the armrest pad. The pad and the armrest are joined by a turn control device so that the pad can be turned 90 degrees, hence facilitating use of a single seat. A double seat is obtained by restoring the armrest pads.
