Practice your new tricks and continue to develop yourself safely. In cooperation with the GRT crew and the Freestyle Trampoline Association, BERG has developed two spotting mats: standard size and XL size. The Spotting Mat XL also easily transforms into a chill lounge bench. The spotting mat is suitable for jumpers 14 years and older. Caution! First, remove the foam pieces from their vacuum packaging, then let them sit for 24 to 72 hours, so they can regain their shape. After you have done this, then put them in the spotting mat.
