TOTIM® Racing Kit Foam Seat in a fully sealed polyurethane foam seat covered with microfiber polyester black color, UNI ISO 3795:1992 average burning rate 0 mm/min (determination of burning behaviour of interior materials), halogen-free. The foam seat shapes and molds around the driver . To make a seat with polyurethane foam in a fully sealed bag after the activation of the foam place the seat cushion in the cockpit or seat shell. Seat the racing driver and form the shape to the driver’s needs, comfort and support. Choose your size based on the amount of space between the seat and the racing driver. The better the existing seat fits the driver, the smaller the cushion you need. For best results we reccomend using too large of a cushion rather than too small. Excess material at the edges can be cut to obtain the necessary shape for the racing driver.
