Cloud 9 ft. s commercial-grade Crayon Bounce House is constructed from heavy-duty, 100% PVC vinyl, from its upright pillars and beams to its slide walls. This (fire retardant, lead-free) puncture-proof PVC material is approximately 5 times stronger than nylon used in lesser-quality units. The PVC will not tear, get moldy, and is far easier to clean. Additional belting reinforcements are found at key stress points, and heavy-duty, multilayer stitching is used throughout. An impressive 30 in. tall mattress provides excellent spring force and cushioning that allows for tall leaps and comfortable landings. The mesh netting also allows children to be supervised. Zippered flaps allow the bouncer to be quickly deflated and taken down for storage. Includes: Instructions, Repair Kit with Patches, 4-ounce Bottle of Glue, and 4 12 in."
