The Lymphaciser is another single purpose rebounder. It does not fold and does not require a balance bar since it is designed to do the Health Bounce and there is no reason someone should need a bar since it has very little bounce to throw someone off balance. This is most compared to the Health Circulator which has an almost identical bounce. The springs on the Health Circulator do not need to be replaces as often a the Lymphaciser. I would say to keep the rebounder close to the initial tensile strength the Lymphaciser springs should be changed every 5 years. So far with the Health Circulator, I have never had anyone call to replace springs. Cellerciser is another brand that never needs to have its springs replaced under normal wear and tear. The Lymphaciser is not good for toning as it has very little bounce. It is strictly a Health Bounce rebounder with low amplitude and super high tensile strength. This has a huge amount of G force without jarring or pronation. This comes with a polyester stitched webbing. This does not off gas like the nylon threading. Those with chemical sensitivities will appreciate this. The Lymphaciser is the coolest looking rebounder I have ever seen with its rainbow on every mat. I love rainbows and rainbows make me happy.
