Buying used inflatables: what to check before you pay

Before you buy a secondhand bounce house: 1) Find the manufacture tag — most units have a realistic commercial lifespan and you want to know the age. 2) Inspect the seams, not just the surface — seam stress is where used units fail. 3) Inflate it fully and listen for air leaks. 4) Check that blowers, stakes, and repair kits are included. 5) Ask why they are selling.
