Abstract: A portable seat and includes a seat and a single adjustable length leg which can be folded against the seat. The leg, when unfolded, lies at an angle of about 135.degree. with respect to the bottom of the seat. The angle between the leg and the bottom of the seat is selected such that the top of the seat will be horizontal when the bottom of the seat is placed on the top of the bumper of a vehicle. The seat is ideally suited for golfers, hunters and other sportspersons who need to change shoes when leaving and returning to the vehicle. The seat may also be used at "tailgate" parties by persons desiring to sit during the party. When folded, the seat can be conveniently stored in the vehicle's trunk or other storage area. The leg may include a foot rest support for the user's feet to more conveniently change shoes or for comfort.
