A trolley includes a main frame, a wheel device, a support frame attached to a front side of the main frame, and a foldable seat assembly attached to a rear side of the main frame. When the seat assembly is in an extended status, a second pair of stands secured to a first pair of stands contact the ground with the wheel device to provide a support for a seat device. When the seat assembly is in a folded status, the first and second pairs of stands fold close to the main frame.
