It keeps the Kids happy for hours and it’s great exercise! – My granddaughters, 22 months and 4 years, love the new medium oval Springfree trampoline. Sometimes mum or myself share one at a time. We sit, lay, bounce, sing songs and read stories in it. It is in constant use. The trampoline is very stable, was easy to assemble with two people using the instructions. The medium oval provides ample room for growing children and will be used for many, many years to come.
