My First Lil Roo is a small Round trampoline with an enclosure and zippered netting for smaller children ages 3 to 6. The weight limit is 100 lbs. The enclosure has a circular steel upright that helps with stability and keeping the netting straight. It's made of "heavier steel than a lot of the smaller trampolines on the market," Pamela DeVore, General Manager, Trampolines USA, Inc., told TDmonthly. Launch date: April 2010.
