The Ultra is Vuly's most affordable trampoline, but with all of Vuly's trademark great features. The Ultra has an advanced rebound system, allowing you to bounce higher on two layers of larger springs that boost momentum. The netting is gentle on skin, but firm to support even the most rugged bouncer. The polyethylene net enclosure provides a safe bouncing environment - no contact with coiles, frame or poles. It tested more rigorously than competing trampolines for performance in high UV and wet weather. Take advantage of the world's best user weight rating - strictly evaluated by third party assessors to Australian Standard 4989. No other Australian trampoline is tested for 750 kg of static load. 'Large' trampolines are best for backyards that have a little extra space.
