We love our springfree trampoline! – Our 9 and 11 year old - plus all their friends, love our medium round Springfree trampoline - we've had it a few years now. It's a good size for our medium sized yard, as we get a pretty large trampoline without comprising on run around area on the grass. Being spring free is great as it lets the kids bounce right to the edge - we opt not to use the net as we believe kids need inherent risk to test their boundaries and limitations. We are comfortable with three big kids bouncing on it at once - four is not as ideal, not due to safety but because kids tend to get a bit silly when they have four or more on a trampoline. Would definitely recommend.
