Lifespan Kids offers a wide range of safe and strong trampolines including signature HyperJump series which comes in various sizes and shapes. The Spring Trampolines offer the highest bounce with zinc plated steel springs and the springless Trampolines feature heavy-duty elastic straps instead of springs for supreme safety, but still retain their bounce quality. There are also trampolines designed specifically for beginners, with low frame height and springless bounce for added safety.
