We have recently bought a 12 foot Vuly trampoline for our two children. Safety was my primary concern for me, so I naturally looked at Springfree trampolines first, but quickly lost interested when I looked at the prices (and heard they weren't as bouncy as other trampolines). We also considered Target/BigW/Kmart trampolines but I was not convinced of the strength of their products and to be honest, I think they look like sagging-nets in people's front yards.
My first impressions of Vuly Trampolines was through their website which I found to be excellent - easy to navigate, a comprehensive FAQ guide and an installation video. I felt confident buying online without a test drive at their showroom. We chose a Vuly trampoline as it had several added safety features, what appeared to be quality materials, and good deals on half-price replacement goods. Having had ours delivered (very quickly, at a date and time that suited me) and well used for a few weeks now I am very happy with our purchase. Installation was solid work but achievable by one person. All materials seem very strong, with several tie-points for the net (I expect there will be little sagging), icons printed on the mat which has prompted several creative jumping games, and a fantastic cubby tent (included in our particular deal) that kept a bit of shade off and created a whole new experience for the kids. Although we paid more than a Target&co trampoline and less than a Springfree, we are really pleased with our trampoline, confident in its quality and anticipate many hours of enjoyment for the family

Approximate cost: $600
