How I Built This with Guy Raz: The Springfree Trampoline

Artwork: Marcus Marritt for NPR

Dr. Keith Alexander wanted a trampoline for his kids. His wife said they were too dangerous. So he decided to build his own.

Over 15 years of research and development he re-engineered the trampoline from the ground up to invent the Springfree Trampoline. Next he teamed up with Steve Holmes, a Canadian businessman, who took a big risk to commercialize it.

Today, Springfree Trampolines can be found in over 15 countries and has sold over 400,000 trampolines.
