Remember the fun we had on trampolines in our backyards when we were children? If we want to re-create this fun outdoor activity for our own children, how do we choose the most appropriate and safe trampoline?

Trampoline retailer Joe Andon suggests that the most popular trampoline for Australian gardens is the round model with the standard black (or polypropylene) mat. "It’s the most popular model by far, because the safety net fits the shape best," he says. "And because of the round shape there is an even pull on the springs so there’s more of a jumping area. The other reason the round model is popular is because they tend to be cheaper than the other models."

Most round trampolines are made from galvanised steel and include padding to cushion the springs and hard metal edges. Mesh safety nets with padded poles are optional, but for a little extra they are well worth it.

For more adventurous and athletic children, the rectangular trampoline with the Olympic-style mesh mat is worth considering. The mesh mat provides more spring than the polypropylene mat, and so more tricks can be achieved on it. With added adventure comes more risk, of course, but the metal and springs can be padded on these models too.

If you’re worried about your children falling from trampolines, one option is to place the trampoline below ground, so the mat is at ground level. There is no compromise in spring and ‘bounceability’, but you can feel more confident that no serious injury will befall your child when he or she starts performing trampoline tricks. Having more than one child on a trampoline at once increases the danger of them hitting each other and causing serious injury.

Trampolines can be as small as 2.3 metres x 1.6 metres for a Junior model, or 2.5 metres in diameter for the round models; and as large as 3 metres x 1.9 metres (or 4 metres in diameter for the round models). To install one in your garden or outdoor area you just need enough space around the trampoline to provide access, and enough room overhead so your children don’t hit their heads. Joe Andon recommends that when choosing a trampoline size, remember that your children will grow. "What suits them today may not be large enough for them in a few years time," he says.
