Are you looking to get your kids away from the TV and outdoors for real fun and exercise? The TT-320 Gym Dandy Pendulum Teeter Totter is equipped with a unique and patented dual pendulum rocking motion that is safer than traditional Teeter Totters. Rubber shock absorbers under each seat cushion minimize the impact to the back and neck. Rubber encased handle bars minimize head injuries caused by accidents. Feel secure knowing that this product comes with a locking safety mechanism that secures it in place when adults are not around to supervise.
