Having good quality springs on your trampoline matters a great deal as it is the springs that influence how well a trampoline bounces. The length and number of the springs will influence how good the bounce is.
As a rule the longer the springs and the greater the spring-count, the better the bounce will be. For example, all quality trampoline manufactures will use 96 8.5inch springs on a 14ft diameter trampoline, whilst an ‘average’ trampoline of the same diameter will have 88 7 inch springs. Though the 1.5” difference in length does not seem significant, it really does make a huge difference. Likewise the addition of 8 extra springs has a big impact.
Though they are not often used on 12 or 14ft trampolines, sometimes we come across 5.5” springs on trampolines of this diameter. A short 5.5” spring is suitable for 8 or 10ft trampolines, but is not for larger diameters.
