Abstract: A tandem seat for a two-wheeled vehicle comprises a bottom of hard synthetic resin to be fixed to a vehicle body, a pad of foam material to be placed onto the bottom and a trim cover assembly for covering the pad. In this tandem seat, recessed grooves are formed in the respective sides of the above-mentioned bottom and pad. These recessed grooves extend along the interfaces between the front and rear seat sections of the tandem seat. The trim cover assembly is thrust into the recessed grooves to separate the front and rear seat sections from each other, so that such an appearance like a split seat is obtained.
