The best test results of all rebounders tested, were reached with the spring-free rebounders.
All rebounder models from bellicon and the two models from JumpSport, the 350 and the 370
qualified as "QiBounders".
Springfree versus spring based Rebounders
Springfree Rebounders, also called "bungee band" Rebounders are the newest evolution in Rebounders. The mat of springless Rebounders is no longer fixed to the frame by metal springs but by high elastic bungee cords.
These are the advantages of springfree Rebounders in comparison to spring-based Rebounders:
1. Higher Efficientcy
The deeper bounce of a springless Rebounder generates automatically a higher G-Force and with that higher efficiency, compared to a spring-based Rebounder. You need less time to achieve the same results on a bungee based Rebounder than on a srping-based Rebounder.
2. More gentle to joints and back.
Besides of being secure and well built, it is the quality of bounce that makes a good rebounder. The bounce needs to be even and the feeling in your body should be pleasant. Compared to the hard bouncing spring-based rebounders, springless bungee band rebounders give you the gentle bounce your body enjoys. Especially if you are concerned with joint or back problems. When you are young, your body can often still compensate jolts that result from hard bouncing rebounders. But if you come towards 40 and over, you need to give your body a correct treatment. Ideal are the Bellicon rebounders as they offer bungee cords adjusted to your weight. But also JumpSport, who offers the same bungee cord type for all weight categories, produces a much more gentle bounce compared to spring based Rebounders.
3. More Fun
Springfree Rebounders based on high elastic bungee bands (especially the models of Bellicon) give you a feeling of weightlessness and flying. There is no comparison to the hard bouncing of spring-based Rebounders. Top quality bungee band Rebounders are so much more fun. See our testimonials.
There is not a single brand in the US that sells spring-based rebounders which are silent. All spring-based Rebounders, even the most expensive like the Cellerciser, squeak heavily after a use of about two weeks of using them. And in most cases, putting oil on the springs does not solve the problem. So you are left for the rest of your days with a squeaky Rebounder. Other the springfree Rebounders: There is nothing that can squeak. The Bellicons are whisper silent, the JumpSports 370 have a very light sound coming from the cover (the "petals") that cover the bungee cords. But event that is no comparison to the squeakiness of spring-based Rebounders.
