The commercial-grade Bounce Castle by Inflatable HQ is a large inflatable bounce house with a capacity of approximately 5 children (800 pounds total). Measures approximately 17' x 13' at its base (including slide exit) and is 12' tall. After the day of playing is through, zippered flaps allow the bouncer to be easily deflated and taken down for storage. Bouncer 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, 15-ounce (0.47mm) PVC. This puncture-proof PVC material is much stronger (approximately 5X stronger) than nylon used in inferior units as it won't tear, fade, wear out with use, or get moldy, and it is far easier to clean. Additional belting reinforcement is used at key stress points, and extra heavy-duty, multilayer stitching is used throughout, further strengthening this tough bouncer. All materials are premium-grade, fire-resistant, and comply with the Lead Free Toys Act. Includes repair kit and ground stakes kit. Always use GCFI-protected receptacles/circuits and take caution to keep blower and power cords in dry locations. Please Note: A blower is required for use and is not included. Make sure bounce house is secured to the ground prior to use. Never use in windy or other inclement weather.
