The Pit Pillow features Smart Mat Technology and has Velcro on all sides, so that several can be connected end-to-end, side-by-side or stacked vertically. The Velcro also allows the Pit Pillow to connect to our other mats or the Air Floor. Convenient handles are located on the side and ends of the mat. (It is not intended for use alone on hard surfaces.) The Pit Pillow may also be used as a "throw mat" for a trampoline. It is great in a loose foam pit to prepare an athlete for a slightly firmer landing.
