Inflate the air bed and listen for the sound of air escaping from the mattress. Fill your spray bottle with soapy water, shake, and spray the mixture onto the mattress where you hear the air escaping. Watch for air bubbles forming around the leak. It may help to sit on the mattress to make the leak more obvious.
