Complete Your Bounce House Party
Most customers add at least one of these — delivered and set up with your bounce house, same trip.
What's Included (No Hidden Fees)
Power: Each bounce house needs 1 standard 110V outlet within 100 feet. No outlet? We rent generators.
☔ Zero-Risk Weather Policy
Bad weather forecast? No problem.
Reschedule at no charge — just reach out the night before your event and we'll move your rental to a new date. We never penalize you for the weather.
Missouri summers bring unpredictable storms — your deposit is safe and your date is flexible.
📏 How Much Space Do I Need?
Most standard bounce houses need a flat area of about 18' × 17' plus a few feet of clearance on all sides. Each product page above shows exact dimensions for that specific unit.
We set up on grass (ground stakes), concrete/asphalt (sandbags), and indoor gym floors (sandbags). Not sure if it'll fit? Just ask — we'll help you figure it out.
