King Koil Air Mattress Losing Air

Start With Initial Material Stretch

King Koil recommends fully inflating a new mattress, letting it sit for 24 hours, and reinflating to the desired comfort. New material can expand and make the bed feel softer without a puncture.

If Softening Continues

1. Check the pump/valve closure.
2. Inspect seams and the pump area.
3. Check the top and underside for punctures.
4. Use a compatible patch only after locating the leak.
5. For a suspected defect, review warranty eligibility before unauthorized repair.

Keep Exploring

A Repeatable Leak Check

1. Inflate the bed to its normal supportive level.
2. Confirm the valve or pump control is fully closed.
3. Leave the bed unloaded for a consistent observation period.
4. Recheck firmness under similar room-temperature conditions.
5. If meaningful loss repeats, inspect the valve, seams and surfaces in a fixed order so you do not miss an area.

Once a leak is located, mark it before deflating the mattress. Use repair material compatible with the surface and allow the specified cure time before reinflation. Flocked areas may require different preparation from smooth vinyl, so product-specific repair instructions take priority.

Frequently Asked Questions

What Should I Check First?

Start with the exact room, sleeper and product configuration involved. Check current manufacturer instructions before relying on a generic rule.

When Should I Consider A Different Airbed?

Compare alternatives when the current bed does not fit the room, repeatedly loses meaningful pressure after troubleshooting, or no longer suits the intended sleeper or setup frequency.
