This commercial-grade Princess Bounce House by Inflatable HQ 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 the nylon used in lesser-quality units as it won't tear, fade, get moldy, and it is far easier to clean. 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 ripstop 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. 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. 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. Model: Princess. Grade: Premium, suitable for rental/commercial use. Capacity: Approximately 8 children (800 pounds total). Dimensions: Approximately 14' tall, base is 13' x 13' (16'-8" long including slide exit).
