The Twin Spin Seat is a super-fun and simple design that kids love. Sit and spin, that's all it takes.
It is constructed of commercial grade plastic and steel. The seat is a rotationally molded heavy-duty plastic that comes in a variety of vibrant colors, and can withstand the elements. The upright is a two-inch outside diameter ten gauge steel pipe that can be powder-coated in a plethora of colors as well.
