1. WEATHER RESISTANCE: Outdoor weather is always unpredictable. Our trampoline spring cover is waterproof, sunresistant, and has a coldresistant, crackproof coating, adapting to all weather conditions. It covers the trampoline springs, protecting them from rain and harsh weather, thus extending the lifespan of your trampoline. 2. DURABLE MATERIAL: For our trampoline safety pad spring covers, we carefully selected quality PVC and PE materials. The density, shockabsorbing, closedcell foam does not absorb water and resists deformation under external force. 3. SAFETY: Our trampoline replacement spring covers ensure your safety. Inside, there is a 0.6inch thick closedcell EPE foam layer that protects your children from injuries while jumping on the mat, giving you greater peace of mind and security. 4. SIZE: The trampoline cover is suitable for trampolines with diameters of 183/244/306/366/396/427/457/480 cm. First measure your trampoline's size (outer frametoframe diameter) and spring length. Do not assume your trampoline size. Ensure your chosen option is correct.
