A standard plyometric box can present some risk to inexperienced or tired athletes and users. The foam jumping platform provides a safe and stable base that eliminates that risk. Because it is a soft material, the consequences of possible stumbling are minimized. For this reason they are used for explosive jumps at high altitudes or by less experienced users. Available in different heights, they can be stacked one on top of the other by means of Velcro. Made of high density Eva foam.
