This trampoline has 40 strong springs which effectively balance the whole pressure of the jumping mat and a safety rounded buckle which can protect you from being scratched during bouncing. Six thick steel legs together support an overall load-bearing capacity of up to 150kg and provide you and your family with a much more stable bouncing space. What's more, there are other additional parts built for users, such as an all-around gapless jumping mat and a sponge-filled edge. Overall, this folding trampoline greatly ensures your safety. During your daily life, because of its compact size, you can freely place it behind the door, in the corner or under the bed.
