The mat is 80 mm thick and made up of two foam layers. The upper layer consists of foam with a density of approx. 240 kg/m³. This corresponds to the normal hardness of most BSW tatami martial arts mats and ensures secure footing. By contrast, the second, lower layer is a soft foam with density of only approx. 30 kg/m³. It offers extensive cushioning, yielding under strong impact and permits intensive throwing training, while helping beginners to avoid injuries. Throwing and falling can be practiced without any restrictions.
Thanks to its dimensions, BSW tatami impact can be integrated as a special training zone in a seamless formation with the remaining mat surface.
