Dr. Keith Alexander is a Professor of Mechanical Engineering at the University of Canterbury, in Christchurch, New Zealand. Over 15 years ago, the father of three decided a trampoline would be a good addition to the family backyard. However, after researching spring-based trampolines for kids it became apparent spring designs were dangerously flawed. He was shocked to discover the high frequency of hospital visits by children being treated for trampoline related injuries, yet it seemed no manufacturers seriously considered the safety of their products. Approximately 100,000 US children are admitted to emergency departments annually. Dr. Alexander set out to create a safe trampoline - removing the hard surfaces that cause injury (including the springs and frame) and the risk of falling off. He also believed it was critical to use the most advanced and highest quality materials to create a superior design. After many prototypes and design trials, Dr. Alexander developed a springless trampoline he was confident was safe for his kids to use. The Springfree™ Trampoline has gone through many design revisions since its original prototype, but the unique safety features of the design remain the same.
