Indoor trampolines, also known as mini-trampolines, are small trampoline kits designed for children between 3 to 7 years old. They are available in many sizes but most of them are portable and smaller than regular trampolines. Average height is about 9 -11 inches off the ground and may be circular, rectangular or square in shape.

Since many emergency room-treated injuries are related to trampoline jumping, before letting kids use indoor trampolines (though smaller and look more harmless), all safety precautions should be taken. Adequate adult supervision is also imperative for all types of trampolines if it involves kids in the trampoline activity.

Indoor trampolines may also be used as a bouncing device by gymnasts or stuntmen to be catapulted into the air. Professional indoor, or Olympic style trampolines, have a webbed surface and are generally much more expensive. They also need folding down and are not suitable for outdoors. Other indoor trampolines may also be used as fitness and weight loss tools.
