Make sure your kids can jump on their trampoline as long as they want with the SkyBound Premium 147 in Trampoline Mat with 88 Rings. The heavy gauge V-rings and bands are strong and limit spring tension, while the 10 rows of heavily-reinforced stitching help prevent fraying. The antimicrobial material resists mildew and water for extended use, and the Sunguard coating has UV protection that hinders exposure to the sun's rays.
