This commercial-grade Sports Bounce House by Cloud 9 is constructed from 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-ounce (0.55mm) PVC. This (fire retardant and lead-free) puncture-proof PVC material is approximately 5 times stronger than nylon used in lesser-quality units as it won't tear, fade, get moldy, and it is far easier to clean. Additional belting reinforcement is used at key stress points, and heavy-duty, multilayer stitching is used throughout. An impressive 30" tall mattress provides excellent spring force and cushioning that allows for tall leaps and comfortable landings. This bouncer's roof shields children from the sun and features a safety escape hatch that's quick and easy to exit in the event deflation occurs during a power failure. The wide, elevated front slide is a safe way to exit this bouncer rather than accidentally bouncing and falling out of the house and onto the ground. Large mesh windows made from rip stop netting won't tear like cheaper mesh and they allow children to be supervised. Zippered flaps allow the bouncer to quickly be deflated and taken down for storage. An upgraded, 1200 Watt, 1.5 horsepower UL-Listed blower with grounded power cord and covered on/off switch is included (Always use GCFI-protected receptacles/circuits and take caution to keep blower and power cords in dry locations). Includes instructions, repair kit with patches, 4 ounce bottle of glue, and four 12" heavy duty metal ground stakes to secure bouncer to the ground. All materials comply with the Lead Free Toys Act.
