CLOUD9 commercial-grade Mega Double Slide Bounce House is a large inflatable bounce house. Constructed from heavy-duty, 100% PVC vinyl, from its upright pillars and beams to its slide walls. All high-stress areas, including the bouncing surface, mattress sides, bottom and slide are made from industrial strength, 18 oz. (0.55 mm) PVC. This (fire retardant and lead-free) puncture-proof PVC material is approximately 5 times stronger than the nylon used in lesser-quality units. The PVC will not tear, fade, get moldy and is far easier to clean. For increased stability, additional belting reinforcement is found at key stress points and heavy-duty, multilayer stitching is used throughout. Zippered flaps allow the bouncer to be quickly deflated and taken down for storage. Includes: Instructions, Repair Kit with Patches, 4 oz. Bottle of Glue and Four 12 in. Heavy-duty Metal Ground Stakes All materials comply with the Lead Free Toys Act. Make sure bounce house is secured to the ground prior to use. Never use in windy or other inclement weather.
