If you go for double safety then you go for a buried trampoline with net. This limits the height of the fall, it is not possible to get under the trampoline and your children cannot fall off the trampoline. So it’s safe! The Hi-Flyer is the best available trampoline in this price range. Are you of the type first to see then believe?
Then visit a show garden and compare some trampolines with each other. Not only visually you will immediately notice some differences. Like the thicker protective rim that a Hi-Flyer has, but your children will also immediately experience the difference in jumping comfort! And then the choice is made.
