Trampoline Cornilleau Spring 12 ft (366 cm) with internal safety net, model 312121

The Cornilleau Spring 12 ft (366 cm) trampoline model 312121 with internal safety net is an outdoor trampoline designed for household recreational use. It provides a 366 cm jumping surface combined with an integrated enclosure that reduces the risk of accidental falls. The design balances a robust frame and resilient jump mat with an internal netting system that keeps the enclosure area free from external obstacles while preserving usable jumping space.

Advantages

The internal safety net places the enclosure posts outside the jumping area, creating a clear and unobstructed bounce surface while improving protection from falls. The trampoline construction offers stable support for family play, with materials intended for regular outdoor use and straightforward assembly. The combination of a large 366 cm surface and internal netting makes the trampoline suitable for varied age groups while helping to limit accidental exits from the jumping zone.

Suitable for

• Family outdoor recreation and active play
• Supervised exercise and coordination training for children
• Backyard fitness sessions and low-impact cardio
• Safe play areas where space-efficiency and enclosure are important

How to use

Install the trampoline according to the manufacturer instructions on a flat, level surface clear of overhead obstacles. Ensure the internal safety net and all frame connections are securely fastened before first use. Supervise children during play and limit the number of simultaneous users according to the trampoline's safety guidance. Regularly inspect the frame, springs or elastic elements, mat, and netting for wear or damage and replace components as needed to maintain safe operation.

Usage recommendations

Position the trampoline on a flat, impact-absorbing base (grass or safety mat), keep the area free of hard objects, and follow local safety guidelines for outdoor equipment. Use the internal safety net as intended and do not modify the enclosure layout. For families, establish simple rules—single jumper at a time for younger children and adult supervision during group use—to reduce the risk of collisions and falls.
