Four U-shaped Legs - Trampoline safety is our top priority when jumping happily. We design safety for trampoline. The legs are arranged and assembled evenly under the trampoline base. 4 U-shaped big legs with 8 balanced contact points to increase the stability of the trampoline. The 5*7 ft trampoline adopts a widened design, which increases the area used for jumping. Safety Enclosure Net and Foam Sleeves - The trampoline design increases the length of the zipper, making it easier for users to enter and exit, increasing the number of buckles for the zipper, and increasing the user's safety factor during use. The foam sleeve ensures that the child will hit the frame will not be injured. Jumping Pad and Spring Cover - Trampoline jumping pad (pp material) that is wear-resistant. Safety enclosure netting, jumping mat and thick padded foam spring cover perfectly overlaps each other eliminating the gaps to ensure your safety while jumping. The trampoline will not fade when it is used outdoors (in order to keep the trampoline's new appearance when it is not in use, it is best to put it under shade.)
