Big Mouth Bounce House

The Costway inflatable castle is a monster-themed play structure designed for children aged three to twelve. It provides a spacious jump zone and an integrated slide for active indoor or outdoor recreation. The unit accommodates two children at once and includes a 550W blower, stakes, a carrying bag and a repair kit. Setup requires only unfolding the house and connecting the blower.

Heavy-duty 420D Oxford upgrade

This model replaces lighter vinyl or nylon bounce houses that tear easily under frequent use. The 420D oxford cloth with a PVC-laminated jumping surface resists abrasion from shoes and rough play much better than thinner materials. The jump is worth it when the bounce house will see regular weekend use or multiple children over several seasons. Buyers who only need occasional seasonal use may find a lighter model sufficient.

Continuous-air blower operation

The 550W blower must run constantly while the castle is in use, which produces a steady noise level and a continuous airflow through the fabric seams. This design keeps the structure firm during sustained jumping sessions rather than relying on a sealed-air chamber that can soften over time. Ventilated mesh walls maintain airflow and visibility throughout extended play periods. The unit must be completely dry before storage to prevent mould growth.

Questions about this item

How much ground space does the 420D oxford-cloth castle need for stakes and safe clearance?

Allow at least a few metres of flat lawn or indoor floor area so the blower can feed air continuously and the stakes anchor the unit firmly without obstruction.

What is the step people most often miss when setting up the 550W blower and bounce house?

Forgetting to close every zip and Velcro flap before switching the blower on — the castle will not reach full pressure if any vent is left open.

How do I use the included repair kit on a tear in the PVC-laminated jumping surface?

Clean and dry the patch area, apply the supplied adhesive, press the patch firmly, then let it cure fully before the next inflation cycle.
