EVA jigsaw mats are available in a variety of sizes from 20mm to 40mm. The thickness of the mats depends on the use of the mats and it is up to the user to determine what thickness is required. 40mm Jigsaw Mats are more suited for falling martial arts including Judo, Jiu Jitsu and Aikido as they offer more protection. Constant throwing and grappling can often lead to injury if adequate padding is not available during impact. Also other aspects of training like rolling and break-falls require protection. Therefore, the thicker the mat the better the protection.The 40mm jigsaw mats also offer excellent value for money because they offer more protection then mats which are half as thick yet not half the price. For this reason they are a more popular choice of jigsaw mats.
