Softer on the body than foam, the 20cm thick Air Tack is also bouncier than a spring floor and is highly versatile. It features 1000-denier double-wall fabric construction with an anti-slip and wear-resistant surface. Designed for robust use, the Air Track does not twist or bend with constant handling and helps to reduce impact readily and significantly. Great for indoor or outdoor use, the 4m Air Track comes with four carry handles and a built-in valve for easy inflating and deflating. Storage is just as easy as well as space saving too.
