Boxing Mats: Boxing mats need to break falls for knockout and trips, be soft enough to fall on but hard wearing and durable for busy areas. High density mats (120kg/cbm) absorb more impact per cbm and are hard wearing. The 20mm 120kg/cbm is high traction and suitable for normal boxing training with head gear. If head gear is not used then you should consider the 40mm 100kg/cbm, critical fall height approx 1.7m. Remember jigsaw mats can be flipped to prolong life and create rings. They work well under a tarp and are the most cost effective mat.
