For group exercise classes you need to use specialized rebound units designed specifically for low impact, group exercise classes and safety.
There are a lot of cheaper ‘mini trampolines’ on the market that are not designed for this type of use.

There are many differences between an Urban Rebounder, and other manufacturers products. The Urban Rebounding workout is designed specifically for the urban rebounder product and we would not recommend that it is safe to undertake this workout on any other equipment that is not designed to the same specification. 

To ensure you get all the health and fitness benefits that rebounding offers and to ensure you have a good experience and that your workout is effective, you will need to invest in a specialized rebound unit thats designed to a high specification for low impact exercise and safety. Cheap mini trampoline type products are unsafe to use in a commercial environment and break easily.

Most importantly the Urban Rebounding Specification is designed for safety to withstand the demands of the Urban Rebounding workout, and the weight and dimensions of the product make it very stable (for example, you can stand on the rim of the rebounder and it won’t tip over) On tightly sprung lightweight units with tiny springs such as the reebok and pt bounce, the participant can’t push down (wihci is part of the proper and safe rebounding technique) into the mat as there is no give ending in the participant jumping up like in trampolining which is not safe on a small unstable unit.

The Urban Rebounder technology has been researched and manufactured to a high spec following 8 years of research in the US, buy respected exercise kinesiologist’s and reboundologists to give you all the benefits from rebounding, like lymphatic drainage, low impact work out, and increase joint stability, doesn’t tip up or move across the floor when on it etc. The urban rebounder is 12kgs in weight and can take a 22 stone person’s weight. Other Inferior 'mini trampolines' products are lightweight between 5 and 7kg,s and can tip up when they are stood on.

Storage
The legs on the Urban rebounding unit are spring loaded so they fold away flat for easy storage. On other products you have to spend a lot of time screwing and unscrewing the legs eventually leading to worn thread and broken rebounder legs.

Whenever we run a training course we always bring a normal 'mini trampoline' to compare the differences with a professional rebound unit because there is such a dramatic difference in the build quality, look and feel and safety. We have replaced many 'mini trampoline units' in clubs, leisure centres and schools.

Maintenance

Our rebounders are very easy to maintain. All of the component parts on the rebounder are replaceable so if anything does need replacing over time it can be done so very easily ensuring the long life of the rebounder.
