Le bloc souple comprend un corps de bloc constitué de polypropylène expansible et une substance de revêtement constituée d'un matériau de caoutchouc de silicone, qui recouvre toute la surface du corps de bloc. Un coupleur mâle et un coupleur femelle sont formés sur la surface supérieure et la surface inférieure, respectivement, du corps de bloc. Un premier aimant est introduit dans le coupleur mâle et un second aimant est introduit dans le coupleur femelle. La surface de revêtement recouvre toute la surface du corps de bloc qui comprend le premier aimant et le second aimant introduits dans ce dernier.
