Although they're associated with a relatively high rate of injury, trampolines are still some of the most entertaining and unique pieces of recreational equipment money can buy. Aside from how much fun they are to use, trampolines offer their users a high quality, low impact aerobic workout that builds muscular strength and coordination, making them valuable training tools for athletes and fitness buffs alike.

Because of their varied applications, trampolines come in a surprising variety of styles, shapes and sizes. While this may befuddle average buyers looking for a basic backyard toy, it allows them to choose a model that closely matches their needs, increasing the enjoyment and safety of their jumping experience. Before you decide to stock a selection of trampolines, keep the following facts in mind:

1. Trampolines are for recreational, competitive or fitness purposes.

2. A trampoline's shape greatly affects its power, safety and overall functionality.

3. A trampoline's size affects its safety and its appropriateness for certain environments.

Stock trampolines that match your clientele's recreational interests

While some buyers may be interested in purchasing a training trampoline for use in a gymnastics or other athletic program, others may simply want a small workout trampoline or fitness trampoline for indoor use at home. The first step to choosing a selection of trampolines to stock is knowing your customers' interests and finding high-quality products that match.

I recommend: Both JumpKing and Sundance Trampoline offer a wide selection of multi-purpose trampolines appropriate for jumpers of all ages. If you're interested in water trampolines, check out the AquaJump selection of inflatable bouncers. If you cater to a gym or fitness club, consider an exercise trampoline machine from GymCor.com.

Choose a trampoline shape that offers the right blend of power and control

Round trampolines are the standard shape for backyard recreational use. Because of their circular design and evenly distributed springs, round trampolines keep jumpers centered over their beds better than any other shape. This is helpful for children or new jumpers who haven't yet mastered the control and balance necessary to keep their bodies in one place. By contrast, rectangular and square trampolines are much more powerful and thus appropriate for training in gymnastics, diving, tumbling and other acrobatic sports.

I recommend: Peruse the collection of round, rectangular and octagonal trampolines at Jumping.com. They even offer competition-sized rectangular trampolines with two-string Australian beds, which offer the highest level of bounce and durability. Trampolines.com also stocks a variety of round models designed for recreational use.

Increase the safety of your trampolines with additional training trampoline equipment

Even if you're using a small training trampoline machine, your safety depends not only on the quality of its construction but also on its additional safety features. Almost every trampoline has padded spring covers, but many manufacturers now offer padded mesh enclosures that greatly reduce the risk of dismount-related injury. Spotting belts and harnesses also help protect gymnasts and divers against impact injuries while training.

I recommend: For recreational safety, Trampoline Parts and Supply makes mesh enclosures and foam padding that fits most standard-sized trampolines. Trampolines USA sells enclosures as well, but they also offer two professional-level training rigs for gymnastics, diving and trampoline spotting.
