The Extreme Family JNR Assault Course is an exciting inflatable challenge designed for high-energy fun at family parties, school events, and community functions. Measuring 12ft wide, 45ft long, and 10.5ft high, it provides plenty of space for kids, teenagers, and even adults to race through obstacles, climb, and slide their way to victory.

Netted mesh windows along the sides allow spectators to watch the action while ensuring safety for all participants.

This inflatable is built to accommodate up to 12 players rotating at a time, making it ideal for large gatherings, fetes, and fun days. Similar to our popular Lightning Assault Course but in a striking new colour scheme, it’s an excellent choice for those looking for something different while keeping the same level of thrilling entertainment. Whether it’s a birthday celebration or a corporate team-building event, this inflatable adds excitement to any occasion.

BJ’s Bouncy Castles ensures a hassle-free experience, providing an electric blower, extension lead, and safety mat for every hire. The inflatable is securely pegged into the grass as standard, or sandbags are provided for indoor bookings. If you need flexibility with collection, late pick-up upgrades are available after 7pm for £30 or after 8pm for £40. An overnight hire option is also available for £70, with discounted rates for multi-day bookings.
