How Do I Find a Hole in a King Size Air Mattress?

Air mattresses are comfortable and easy to set up. Many people use them for camping or spare beds, which means they are often in storage and not frequently used. Before you head out of town for your next camping trip or invite someone to spend the night, check your air mattress for a hole. Do this at least 24 hours before you need to use it, so you can repair the leak and make the mattress airtight.

  Sit on your mattress and listen for a hissing sound. This guides you to the leak. If you don't hear anything, slowly wave your forearm a few inches over the mattress in a back and forth motion, feeling for a breeze or airstream coming from the mattress.
