Introduction
If you’ve got a budget of $300, you’re sitting in the sweet spot of the inflatable water‑slide world.

Loose anchoring is the #1 cause of slide instability.
Wind Safety
Inflatables and wind don’t mix.
0–10 mph: Safe
10–15 mph: Caution
15+ mph: Stop use
If sprayers start blowing sideways, that’s your early warning.
Climbing Wall Safety
One climber at a time
Dry steps before use
Mesh sides fully secured
No pushing or racing on the wall
Splash‑Pool Safety
Keep the landing zone clear
Remove toys and hard objects
Maintain shallow water
Check for debris before play
Safety QuickCheck
Before every play session:
Stakes fully inserted
Blower tube straight
No wind gusts
Landing zone clear
Sprayers flowing evenly
Surface Setup Guide
For best performance:
Use flat, grassy ground
Avoid slopes
Remove rocks and sticks
Use a tarp for extra protection
Angle the slide toward natural drainage
