Most inflatable water toys are about as stable as a prolonged game of Jenga. But thanks to witchcraft, voodoo, or possibly even science and intelligent engineering, this inflatable mat can support up to six people without sinking or flipping.
In fact, with 90 square feet of surface area it can support up to 1,000 pounds, so it's strong enough to let you run, jump, and even do cartwheels on it. Everything you've always been encouraged to do when near the water.
Inside, the two-inch thick mat is supported by thin PVC piping and an air bladder that can be inflated in about five minutes. It can also be easily collapsed and carried in a shoulder bag, because at $1,000 you're not going to want to leave this inflatable toy just lying around. [Hammacher Schlemmer]
