Best investment for safe fun and fitness! – Kids are 7, 7 and 9. We upgraded to a new Large Oval after 7 years of hard use from young kids, and two house moves with the trampoline. The upgrade process was easy, fast and affordable - and the best part is the new 10 year warranty will take us through til the kids are adults! The springfree trampoline is not only safer for jumping, but gave our girls (so close in age) the opportunity to play in our yard safely rather than go to the local park when I can watch from inside. They live between the trampoline and the kitchen! Screen time is self regulated and the kids always choose to play outside on the trampoline instead! The large oval has been awesome for us 'oldies' to show the kids how to really jump! Never had any troubles or injuries on our springfree, and I work in an emergency department where I see it all! Would choose no other brand than Springfree for this exact reason!!
