Friends just bought a backyard trampoline.
Straight off, as a gymnastics professional, I advise everyone against backyard trampolines. I am surprised they are still legal in Canada.
Kids should do trampoline only under the supervision of trained coaches on properly maintained equipment.
If you insist on putting a dangerous trampoline in your yard, consider a trampoline without springs. For example, the Spring Free SF90E.
As backyard tramps go, I am impressed. This company is focused on safety.
Eliminating the springs is a great innovation!
But I dispute the company’s claim that “SpringFree is the Safe Trampoline!”.
It’s a safer trampoline. But the reaction force from the elastic bed can still injure children.
