Remember as a kid you there were those giant and potentially dangerous trampolines? Now we have something called the Jump-O-Lene which can accommodate two kids. It has an 82 inch jumping surface. It is filled with air for that bouncy effect. The mattress is made up of two separate heavy duty vinyl cushions for extra bounce. Repair is easy. it comes with a kit. The Jump-o-Lene supports maximum of 120 pounds. It inflates with any air pump or 120 volt AC electric pump. The dimensions are 82 inches deep and weighs 21 pounds.
