The main difference is in the safety measures taken in the design. Children’s mini trampolines tend to have padded handrails and enclosure nets, which make them extra safe for the kids. They also tend to be more colorful with brighter colors and have themed mats to make them more exciting for the kids. However, other than that, there isn’t much of a difference between them and adult mini trampolines and the same trampolines can often be used by both children and adults.
