It comes down to a few factors:
1. How much space do you have for a trampoline?
2. Who will be bouncing on the trampoline?
Our Flex100 and Flex120 model is perfect for young bouncers and small sections. However, if you have space and want to push the limits with some aerial tricks then our larger model trampolines will be a better fit. Our Flex140 is our most popular sized trampoline having more space to learn and develop skills. If you have space then our massive Flex150 is great size trampoline for multiple jumpers and big tricks.
There is a detailed specifications list on the trampoline page so that you can calculate how much space you will need.
