An air mattress is a convenient, easy-to-store item, perfect for accommodating friends who come over and need a place to sleep for the night. However, even the tiniest hole can leave you waking up on a completely deflated mattress. Finding a hole in an air mattress can sometimes feel as difficult as finding a needle in a haystack, but there are several solutions provided by manufacturers. First, check the valve, as it is often the source of the problem. If the valve doesn't reveal the leak, you can try other methods.
Steps
Inspect the Valve

- Move the bed sheet to another area, away from the spot you're inspecting for holes, to avoid any interference.

- If you're camping, it might be a good idea to do this inside the tent to avoid wind and noise.
- Make sure there's enough light. You need to be able to see clearly while searching for holes.

- You can blow air into it or use a pump to inflate the mattress. Many air mattresses come with a pump to help with this.
- Do not over-inflate. Most manufacturers warn that over-inflating can cause the mattress to burst.

- Ensure that the valve cap is securely closed onto the valve body.
- For double-lock valves, make sure the valve body is pressed tightly against the stopper behind it.
- If there is an issue with the valve, it may be irreparable. However, if the valve cap isn't properly sealed, you can try adding a small piece of plastic to seal it temporarily.
- If the valve cap is fully closed and the valve body is securely pressed against the stopper, proceed to look for holes in the mattress.
Use Dish Soap

- If you don't have a spray bottle, you can use a cloth soaked in soapy water.
- A sponge soaked in soapy water can also be effective for this method.

- Regardless of the method used, always inspect the valve area first, as it is the most likely place for leaks.
- If you notice bubbles forming near the valve, check to ensure it is properly sealed.

- Leaks will be detected when soap bubbles appear.
- Don’t worry if soap gets on the mattress. You can wipe it off, and the mattress will dry.

- It’s easier to mark the leak if you dry the area first.
- You can also use fabric tape or a highlighter to make the mark more visible once the mattress is dry.

- If you don’t dry the mattress before storing it, mold may develop. It's essential to ensure the mattress is completely dry before storing it.
- Make sure the mattress is fully dry before using any patch to repair it.
Inspect the Mattress

- Even a tiny hole, like the size of a pinprick, can be visible when the mattress is inflated.
- Make sure to perform this step in a well-lit area.
- Inspect each area methodically. Start with the top of the mattress, then check the edges, and finally the underside of the mattress.
- Pay close attention to the seams, as they are often where tears occur.

- If possible, dip your hand in cold water first. The air escaping from the mattress will accelerate the evaporation of the water on your skin, making it feel colder.
- Gently move your hand along the mattress surface. If you move too quickly, you may not notice the subtle sensation of the air leaking out.

- Your ear is more sensitive when checking for leaks. The escaping air will create a hissing sound.
- This listening method is especially effective for larger holes.
- Pay close attention to the seams on the mattress, as they are often the most likely places to leak.

- Some manufacturers provide instructions on how to patch the leak. Others may suggest sending the mattress for repair.
- Do not attempt to repair the mattress without guidance from the manufacturer, as different materials may require different methods.
- Once you find one leak, continue to inspect the rest of the mattress. There may be multiple holes or tears causing the issue.
Submerge the Mattress in Water

- The mattress will absorb water when submerged. The fabric can become soaked.
- When the mattress gets completely wet, the seams may start to deteriorate, and the protective layer on the synthetic fabric could peel off.

- If inflated too much, it will be difficult to submerge it in a pool or bathtub.

- Check if you can press out the air from the valve.
- The escaping air will create a stream of bubbles forming around the leak. Look for these leaks as you press around the valve.
- Submerge each section of fabric in the water. Look for the bubbles rising to indicate a leak.
- Take it section by section. It’s easier to observe small areas rather than trying to find the leak across the entire surface of the mattress.
- Focus carefully on the seams. The seams are often where leaks and tears occur.
- Mark the leak with a permanent marker. Permanent markers are less likely to smear on wet surfaces.
- You can dry the area around the leak with a towel to make it easier to mark.
- Once the mattress is dry, you can use fabric tape or a thicker marker to clearly highlight the leak.

- If you don't dry the mattress before storing it, mold may form. It's crucial to ensure it is fully dry before putting it away.
- Before applying any repair materials, make sure the mattress is completely dry.
Use a garden hose

- A soaked wooden table can be quite inconvenient. This method requires a hose and a strong water source.
- You may also place the mattress on the ground while using this method. Just remember to cover the wooden surface if you place the mattress on it.

- Focus on spotting the bubbles forming where the water flows.
- Bubbles escaping from the valve area indicate a leak. Check the valve to ensure it is fully closed.

- Pay close attention to find the stream of bubbles coming from the leaks on the mattress.
- Look carefully around the seams to see if any bubbles emerge. Bubbles indicate a leak, and seams are often the areas most prone to tears and damage.

- You can wipe the area around the leak with a towel to make marking easier.
- Once the mattress is dry, you can mark it more clearly with fabric tape or a thicker permanent marker near the leak.

- If you don't fully dry the mattress before storing it, mold may form. It's important to ensure the mattress is completely dry before storing.
- Make sure the mattress is 100% dry before applying any repair methods to patch it up.
Advice
- Use soapy water to easily spot bubbles when the water reaches the leak.
- Rinse off the soap from the mattress once the leak is found, and let it dry completely before proceeding with any repairs.
- Consult the manufacturer for the best repair instructions. Some manufacturers provide free repair kits or appropriate guidance.
- When inflating the mattress, light an incense stick and let the smoke enter the mattress. As the air escapes from the hole, the smoke will also escape with it.
- It might be better to purchase a new mattress. Consider how much time you will spend locating the leaks.
- Try using a smartphone with a decibel meter app. Turn off all background noise and move the phone across the mattress to detect any increase in sound. To check, move your sensitive lips over the area to pinpoint the exact leak.
- Place the mattress in an open space and lie down on it to see if you can feel air escaping.
- Some methods suggest adding water into the mattress through the valve. However, avoid doing this as it’s difficult to dry the inside of the mattress, and the water can cause mold to form, damaging the mattress.
Warning
- Do not add water inside the air mattress. You won’t be able to dry it before mold develops.
- Do not place the mattress on sharp objects when inspecting it.
- Ensure the mattress is completely dry before storing it to prevent mold growth.
- Do not overinflate the mattress to avoid bursting it.
