This is the horizontal version of beach volleyball that challenges up to four players with 360° ball-bouncing action. Ideal for sand—but allowing for exuberant play on grass or pavement—the game’s six-sided trampoline sets up in seconds, offering two players a taut, 24"-diameter nylon rebounding surface on which to slam one of the two included 5"-diam. rubber balls at oblique angles to prevent a successful return volley. Four-person contests introduce the second ball into play, allowing for two-at-a-time slams, feints, dives, and saves as well as double the scoring opportunities. The trampoline’s six heavy-duty plastic legs hinge inward from their locked play position to provide easy portability and storage. Includes playing instructions. 24" Diam. x 81/2" H. (3 lbs.)
