Why Does Air Mattress Deflate? 5 Steps To Fix

Air mattresses are a convenient and portable bedding option that many people rely on for camping trips, guest accommodations, or even as a temporary solution for their bedroom. 

However, deflation is one of the most common issues that users face with these bedding items. So, why does an air mattress deflate?

Deflation can occur for several reasons, ranging from normal air escape to valve problems and punctures. Let’s explore why these products deflate and how to fix them to ensure a comfortable sleeping experience!

Why Do Customers Choose An Air Mattress?

These products provide the utmost convenience and affordability.

There are several reasons why customers choose an air mattress over a traditional one. One of the main reasons is their convenience. 

They are easy to set up and take down, making them ideal for guests or while traveling. Additionally, they are highly customizable in terms of firmness, allowing users to adjust the level of support to their liking.

These items are also relatively affordable compared to traditional ones, making them a budget-friendly option. Plus, many find them to be more comfortable than traditional ones due to their ability to conform to the body’s shape and distribute weight evenly.

Why Does Air Mattress Deflate?

The product is losing air due to many reasons.

There are five main reasons why an air mattress may lose air and deflate. Let’s see these 5 problems that cause your air mattress to deflate!


Air leakage can occur due to a puncture, tear, or rip in the material. Over time, the seams or the valve can become loose or damaged, causing the bed to slowly lose air.

If you or your kids usually jump on it or stand on it, leakage can also occur due to excessive pressure.

Temperature Changes

Air expands and contracts with temperature changes, affecting the pressure inside the mattress. In colder temperatures, the air inside the item can contract and decrease in pressure, causing it to deflate. 

In contrast, warmer temperatures can cause the air inside the product to expand, leading to overinflation and possible damage.

The Maximum Weight Is Exceeded

Most air mattresses have a weight limit, and exceeding this limit can cause the item to lose air and become uncomfortable or even unusable. Overloading the item can strain the seams, the valve, and the material itself, leading to leaks and punctures.

Valve Problems

The valve is a critical component, as it controls the airflow in and out of the item. It can become damaged or loose, and the air leaks out of the mattress slowly. In some cases, the valve can be difficult to close properly, leading to air loss.

Poor Quality

Air mattresses made from low-quality materials or with subpar manufacturing processes can be prone to punctures, tears, and leaks. Poorly constructed seams, valves, and materials can all contribute to air loss and deflation.

You should choose a trustworthy name to get your item.

How To Fix If The Air Mattress Deflates?

Fortunately, fixing a deflated air mattress is usually a straightforward process. Here are the steps to repair a bedding item that has lost air.

Step 1: Check The Leak/Hole

Carefully inspect the product for any signs of damage, such as punctures, tears, or holes. Listen for hissing sounds or use a spray bottle with soapy water to detect the leak.

Step 2: Patch The Leak By Patch Kit

Once you have found the leak, use a patch kit specifically designed for air mattresses to repair the hole. Follow the manufacturer’s instructions carefully, and clean the area around the hole before applying the patch.

Step 3: Adjust The Valve

Check the valve to ensure it is securely closed and adjust it if necessary. Sometimes, the valve can loosen over time, causing air to escape.

Step 4: Inflate The Mattress

After patching the leak and adjusting the valve, inflate the bed to the desired level. Use a pump, either electric or manual, and follow the manufacturer’s instructions for the correct inflation level.

Step 5: Add The Pad/Protector

To prevent future damage to the item, consider adding a pad or protector on top of it. This can help protect the item from punctures, tears, and spills to extend its lifespan.

How To Preserve An Air Mattress For The Long-Term?

Storing it carefully can prolong its lifespan.

It’s essential to take proper care of it to ensure your product lasts as long as possible. Here are some tips for preserving it for the long term.

  • Proper Storage: When not used, deflate and store the mattress properly in a cool, dry place. Avoid storing it in direct sunlight or a humid environment, as this can damage the material.
  • Avoid Over-Inflation: Over-inflating can leave stress on the seams and valve, leading to leaks and punctures. Follow the manufacturer’s guidelines for the proper inflation level.
  • Use a Pad/Protector: To prevent holes, tears, and spills, consider using a pad or protector on top of it. This can help extend the lifespan of your bedding item.
  • Handle with Care: When setting up or taking down the air mattress, handle it carefully to avoid causing damage. Avoid jumping or bouncing on the bed; use caution when folding or rolling it up.
  • Check for Damage: Regularly inspect the bed for any signs of damage, such as punctures, tears, or leaks. Repair any damage promptly using a patch kit specifically designed for air mattresses.


Why does an air mattress deflate? Now you know the answer. By understanding why it may reduce and following the appropriate troubleshooting steps, you can enjoy a comfortable and restful sleep on your item for a long time.


Is it normal for my air mattress to lose air?

Yes, it is normal for this product to lose air over time due to natural air escape through the material or valve. Yet, when the air loss is significant or consistent, it may indicate a leak or puncture that needs to be repaired.

What is the weight limit for an air mattress?

Most standard models have a weight capacity of around 300 to 600 pounds. Meanwhile, some high-end models are capable of supporting up to 1,000 pounds. It is important to check the manufacturer’s specifications to ensure the bedding item can safely support the intended weight.

Can an air mattress be used every day?

While an air mattress can be used daily, it is not recommended as a long-term solution for regular use. Using it as a primary sleeping surface for an extended period can also lead to sagging, air leaks, and reduced durability.
