The seat is made of plastic and is attached to the base of the interior by means of double screws; with this accessory you can complete the look of the interior (single driver, full 4 seats layout or eventually only front raw seats) with the style that you prefer; you can keep the seat(s) full black or play and have fun to paint it with the colors that you want.
The steering wheel (#BDCR-RR-SW) and the interior (#BDCR-RR-DC) are sold separately, so it necessary to buy both to achieve the same aesthetic result as in the pics.
