What Causes Air Mattresses to Deflate Overnight?

Is your air mattress leaking from night to night, so you have to wake up on the floor in the morning?

Despite the fact that inflatable air beds deflate so often while in use, inflatable air beds are inarguably one of the most comfortable choices on the market. What causes your blow-up bed to lose air overnight?

A mattress should always have the right amount of air inside. As the weather gets cooler, the mattress’s air tends to condense, and the bed deflates.

The air pressure in the bed decreases as it gets low, which makes it more prone to tears and holes.

Temperature plays an important role in minimizing the chances of holes and tears developing. When filling up the bed, measure the temperature, and make sure you maintain it throughout the night.

Reasons For Air Mattresses Deflating Overnight

Your situation may be caused by several factors. In addition to addressing these reasons, we also provide you with a few tips to avoid further mattress deflation. You deserve a good night’s sleep, so let’s help you get it.

Air mattresses deflate overnight due to the following reasons:

1. Holes That Leak

It isn’t the strongest product you will ever own. In many cases, these beds are made from thin materials that are susceptible to puncturing, stretching, and rupturing over time; therefore, you can avoid this.

There is a greater chance of these problems occurring if your bed is heavily used on a daily basis (nightly).

Air beds are susceptible to wear and tear, but there are some ways to prevent it from happening right away. Mattresses will eventually succumb to their imperfections.

2. The Pumping Predicament

The ideal situation would be to be able to disconnect the pump without releasing any air when you have finished filling your mattress with either a manual pump or an electric external pump.

It is nearly impossible to find a blow-up mattress that is completely air-tight, since all blow-up mattresses employ external pumps.

Since most inflatable beds are filled with air by an external pump, when you detach the pump, some air will leak out. This ongoing issue has been addressed in some products by using built-in pumps.

Pumping up and maintaining such options is the easiest. The mattresses fill with air in between four and six minutes, so you can easily make sure you or your loved ones have a good night’s sleep.

3. Immediate Use

There shouldn’t be a problem right away. Consider whether you inflated your new air mattress and slept on it that night if your new air mattress deflated. Your new air bed will benefit from some time spent sitting.

I recommend inflating it and leaving it alone for about two days. The air bed will form properly when the fabric stretches and the air settles.

You can prevent the mattress from expanding correctly if you put pressure on it immediately.

If you damage it soon after purchasing, you may increase your chances of losing it. Before you can use your air bed, use another mattress for a few days.

4. Temperature

There is no secret that evening air is cooler than daytime air. The air inside the mattress condenses when the sun goes down and the room temperature drops.

This can be explained by the Ideal Gas Law, a fancy scientific equation. The same concept applied to your air bed as it did to NBC Sports’ analysis of the law’s effect on football during NFL games.

A Sports Science experiment exposed balls to 10-degree temperatures for sixty minutes, resulting in a decrease in ball pressure from 13.5 to 11 PSI.

Even though that’s an interesting fact, it’s important to realize that when your mattress is exposed to cold temperatures during the night, it loses some pressure, which means you wake up feeling deflated.

5. Improper Use

There’s no better way to end the day than to go to bed after a long day of work. If you are wondering how to properly inflate your bed, you do not want to read an entire instruction manual.

There is a good chance that your bed will not perform to its maximum potential if you disregard the instructions in the manual.

It is in your best interest to read, understand, and implement the steps listed; they were put there for a reason. This will ensure that your inflatable bed maintains air pressure and also extend its lifespan.

6. Overinflating The Bed

Overinflating The Bed

Air mattresses can be very easy to overinflate if they are manually inflated. It may seem logical to fill the bed with too much air.

Consequently, as the air mattress deflates over time, you will still have enough pressure to keep you comfortable.

However, overinflating the bed can damage the seams. There is a possibility that they could tear, leading to leaks in your air bed. Your chances of experiencing this problem increase if you overinflate your mattress.

Make sure the air bed is inflated to about 90 percent of its maximum capacity. If you do this, you’ll have plenty of support, and you’ll be able to maintain the condition of the bed.

7. Pet Access

It is also possible that a pet has gotten on your air mattress and caused it to deflate. Cats and dogs can tear mattresses with their claws digging into the material. There is, of course, a possibility that air will leak from the tear.

Declawing your cat is not necessary. If you do plan on allowing your pets in your guest room or bedroom, you may want to reconsider. It is possible to damage the mattress just by walking on it.

Cats and dogs sometimes scratch air mattresses without intending to. Natural tears can occur if they have very sharp claws. Avoid letting pets near the bed if you want to avoid rips.

8. Excessive Weight

The weight limit on most air mattresses must be adhered to. Overloading the air bed could cause leaks if the weight exceeds that limit.

It is possible to support more weight on some mattresses than on others. The weight capacity of most king air beds is higher than that of twin or full air mattresses.

The amount of weight you and your partner together may not require a larger mattress. If you do this, your air bed will support both of you. You can occasionally go over the limit, but you shouldn’t do so regularly.

9. Child Access

It’s possible that your children are the cause of your air bed not holding air, as well as your pets.

Kids may not realize how important it is to protect their beds. As a result, pressure and tears may result from jumping, walking, or sitting in one place for a long period of time.

It is important to teach your kids to be careful before letting them use air mattresses or access yours.

Make sure they are old enough to handle it. They can also only be allowed in the room when you are there to supervise them.

Tips to Avoid Deflated Air Mattresses

Tips to Avoid Deflated Air Mattresses

You can increase the lifespan of your air mattress by following these tips.

Lay Flat

The best way to maintain your mattress is to lie flat on it. There is a danger that holes and tears may occur if you apply all your body’s weight to one specific section while sitting on the ends.

Laying flat on the bed during use evenly distributes your body weight, which reduces pressure on the mattress and reduces air leaks.

Take Care When Folding

It is common for careful handling to be overlooked as this is the last step in the process of using a mattress.

Nevertheless, this is an essential step that should be done with precision each time to ensure your blow-up bed lives as long as possible.

During folding, the materials of the bed will stretch, which increases the likelihood of tears.

The improper folding of the material will exacerbate minor holes that are already forming and cause increased leakage over time.

In order to avoid this, ensure that you follow the instructions in the user manual when folding the tissue.

Despite their appearance, these steps are neither tedious nor pointless. Those instructions are included in your air mattress’ instructions to ensure it lasts as long as possible.

Do All Air Mattresses Lose Air?

Do All Air Mattresses Lose Air

Despite the fact that all air mattresses lose some air in the night, they are incredibly different from one another.

Air is lost when you lie on a mattress that is too low or too high, and both play a role in the amount of air that is lost.

In colder temperatures, mattresses lose air more quickly, and at higher altitudes, mattresses are flatter. It’s not that air mattresses are immune, but some perform better than others.

How Can You Stop This?

The air leaking from your mattress cannot be permanently stopped. Unless your mattress is designed to lose no air whatsoever, it will burst. However, you may improve the performance of your mattress by modifying your environment.

A warm sleeping area reduces air loss in the mattress, and laying flat on the mattress prevents air from being pushed out rapidly. A small space is put under a lot of pressure when people sit on their mattresses.

When you wake up in the morning, you’ll find the mattress even flatter because this pressure forces the air out of the mattress faster. A hot air mattress can be used on an upper floor of your home to change elevation. 

It is also possible to use space heaters outdoors. A never-flat pump air mattress is another option.

How Long Does An Air Mattress Last?

If you take care of an air mattress properly and use it occasionally, it will last for two to eight years.

After each use, deflate your air mattress fully and fold it into a bag, storing it away from sharp objects and in a cool, dry place away from sharp objects to extend its life.

When to Replace Your Air Mattress

If your air bed is constantly losing air or deflating, you may not always be able to fix it. There is a possibility that you might not be able to find the source of the leak despite trying different methods.

There may be a hole, but no patch large enough for it to be covered. In any case, it may be time to replace your old mattress.

A relatively new air mattress, however, could still be covered by the manufacturer’s warranty. It may be possible for the manufacturer to replace your product depending on the cause.

Final Words

The design of air mattresses, the temperature, and the pressure put on them cause them to deflate overnight. There is no airtight air mattress.

It’s important that the air mattress you’re sleeping on has some breathing room, and just by lying down you’ll lose a small amount of air. There is a difference in temperature between day and night.

Mattresses condense when the temperature drops. There seems to be even more air loss in the mattress, but it is simply undergoing physical changes. A rising temperature will make the air take up more space.
