With 30+ years experience in trampoline production we've learnt what makes a trampoline fun, safe & long lasting. A lot of the trampolines you'll see for sale on Amazon have been made in our factory under OEM. The Zero Gravity brand is our premium offering and utilises the latest technology for a great value, fun, safe & long lasting trampoline. Plenty of models for sale tick a lot of the boxes but can you tell if they are built to a budget with corners cut? Just a few tips on what to look for.
ENCLOSURE- There are two types of enclosure either an inner (attached to the edge of the jumping mat) or an outer (fits on the outside of the frame). Both are safe but if you are looking at a model with an outer enclosure ensure that the padding is as thick as possible over the frame as your childs head can easily come into contact with this whereas with an inner enclosure this cannot happen.
PADDING- The thicker the better. Find out what the outside of the padding is made from, PVC is preferable as it doesn't rot under UV light unlike PE which can crumble after a year or so.
LEGS- The more legs the trampoline has then the shorter the lengths of the upper frame sections can be. A shorter piece of steel is less likely to bend than a long length so the frame should be stronger.
JOINTS- The majority of trampolines are made from welded steel (does not apply to Zero Gravity which is weldless). The weld is the weak point on a frame so check to see if it has supporting plates to strengthen each joint. If an image is not shown of this component assume it doesn't or ask the seller.
MAX USER WEIGHT AND SPRINGS- Trampolines should only be used by one person at a time. Does your child really weigh 150KG or 23 stone? Trampolines should be tuned by the manufacturers for the weight of the user. If its over-sprung in order to increase max user weight then it could be less bouncy than one with a lower limit.
