Bounce houses are one of the most beloved party activities for kids — and when run properly, they're also very safe. That said, most bounce house injuries happen not because of equipment failure but because of preventable rule violations. As a Chicago parent renting a bounce house, knowing the safety basics is part of being a great host. Here's everything you need to know.
Most standard bounce houses are designed for children ages 3 to 14. Children under 3 should not be in a bounce house with older kids — the size difference alone creates a serious risk of collision injuries. Toddlers and babies should never be inside an inflatable, full stop.
Weight limits are printed on the inflatable itself. Standard units typically cap at 600–800 lbs total inside capacity, but that's not an invitation to pack eight adults in at once. Adult use should be limited to gentle entry and exit when helping a small child — not active bouncing. The unit is engineered for children's body weight and movement patterns.
Every bounce house rental should have at least one dedicated adult supervisor watching the inflatable at all times. Not glancing over from a lawn chair while scrolling a phone — actually watching. The supervisor's job is to:
If your party has 20+ kids, consider having two adults take turns supervising in 30-minute rotations so no one gets fatigued or distracted.
Chicago weather is notoriously unpredictable, and this is one area where there is absolutely no compromise:
Do not operate a bounce house in: sustained winds above 20 mph, lightning or thunderstorm conditions, heavy rain, or any severe weather. Deflate immediately if any of these conditions develop during your event.
An inflatable that catches a strong gust can tip, shift, or become a serious hazard. The stakes we use during setup anchor the unit — but stakes have limits. If the weather turns, the right call is to get the kids out, turn off the blower, and wait it out or call it. No party is worth a preventable injury.
Light drizzle is a judgment call — the inflatable surface becomes slippery, so it's generally advisable to pause bouncing until it passes. Always monitor the forecast and have a weather backup plan. Read our guide: How to Plan the Perfect Bounce House Birthday Party in Chicago.
Before any child enters the bounce house, make sure they remove:
These items can damage the inflatable material and — more importantly — injure other kids during the inevitable collision that happens when eight children are bouncing in an enclosed space. Post a reminder near the entrance and have a basket nearby for kids to drop shoes and accessories.
This rule protects both the inflatable and the kids. Food and drink inside a bounce house can cause slipping hazards, choking risks, and staining damage. Keep all food, drinks, gum, and candy well away from the inflatable — ideally at a table 15+ feet away. The same goes for silly string, which can permanently damage inflatable material.
The blower is what keeps the bounce house inflated. Never turn off the blower while children are inside. If the blower stops for any reason — a tripped breaker, a disconnected cord, a power outage — calmly and immediately help all children exit the inflatable before it deflates fully. The deflation process is gradual, not instantaneous, so there's time to act.
What to do if the bounce house deflates: Stay calm. Have children exit one at a time through the opening. Check whether the blower is still running and the power cord is connected. Check your home's breaker box for a tripped circuit. Call Pure Play at (773) 584-7821 if the blower has a mechanical issue — we'll troubleshoot with you.
Overcrowding is the number one cause of bounce house injuries. More kids = more collision risk. Check the capacity label on your specific unit and enforce it consistently, even when kids are begging to all go in at once. Running a simple rotation — 5 minutes in, then swap — actually keeps kids more engaged and excited than unlimited free-for-all access.
