摘要： The invention relates generally to a lightweight, collapsible, and portable wheeled seat, e.g., a wheeled office chair or stool, for travel, storage, and mobility. The seat includes a seat base member and a seat surface member collapsible between an open, extended position, which is configured to provide a seating surface, and a collapsed, closed position. The seat surface member includes a central seating surface member fixed to the seat base member that has an outer perimeter, and a pair of oppositely disposed and generally u-shaped seating surface members pivotally secured to the seat base member. Each of the generally u-shaped seating surface members include a pair of leg portions that extend from a base portion thereof, or an inward directed perimeter and a portion of each inward directed perimeter has a shape that substantially complementarily corresponds to a shape of a portion of the outer perimeter of the central seating surface member.
