Costway Inflatable Castle Bounce House Big Mouth 550W Blower

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.
