Sleep Number beds use air chambers to allow users to adjust the level of support of the mattress. Finding a leak in a Sleep Number bed can be either a simple task or a challenge, depending on the size of the leak. However, it can be done. You can use a few household items to find the leak in your Sleep Number bed.
Turn off anything making noise in the room where your Sleep Number bed is located. Remove all the bed coverings from your mattress.
Listen carefully to see whether you can hear the leak. Put your ear close to the mattress. If you can't hear any air coming out, use a piece of aluminum foil. Move it around the mattress as you listen. It will vibrate when it is on the leak.
Fill a spray bottle with water and several drops of dish soap.
Spray your Sleep Number bed mattress in sections. When you come across the leak, the soap will bubble.
Mark any leaks you find with a permanent marker so you can easily find the places you will need to repair.
