Why Do Air Mattresses Deflate Overnight?

Q & A

It's become a common cliché that everyone who has ever slept on an air mattress can testify to: You go to bed feeling bouyant and happy, only to wake up flat on your back, side, or tummy.

So why does air mattress deflate overnight? This is probably the most common question on the lips of everyone who has owned and slept on one of these.

The truth is that there are so many reasons why this may happen. Depending on the quality of your mattress and other personal circumstances, there is usually a specific reason out there for you.

Let’s take a look at some of the reasons why you may experience air loss in your inflatable mattress by the time you wake up in the morning.

Air Tightness

The truth may be hard to say but simply sets you free once you muster the courage. The simple truth is that no air mattress on the market is 100% airtight.

Yes, that’s right!

You may be asking yourself why that is the case. Well, the simple explanation is that no current technology available today has been able to achieve that.

If your Intex air mattress deflated overnight, know that you are not alone. This problem is common with almost every brand.

Sure, some manufacturers make claims about incorporating “advanced air tight technology”. However, with all the technology in the world, a 100% airtight mattress may never be possible.

Every airbed needs some room to breathe. This means there will always be a likelihood of completely bursting if it were manufactured to be 100% airtight.

This is one of the main reasons why they lose air overnight.

Does this mean you should buy just about any inflatable mattress you come into contact with since they all lose air? No! It is important to choose a model that is designed to keep optimum amount of air once inflated.

Remember, the amount of air lost by different brands of mattresses can be significant. This is why opting for the best designed model out there is advisable.


If you think temperature has no effect on the amount of air loss experienced by your mattress then you are in for a shock. Temperature variations can be a major determinant in how much air is retained by a blowup mattress throughout the night.

It is vital that you try to protect your airbed from extreme temperature changes within its surroundings. Typically, the lower the temperature, the higher the amount of air loss experienced.

Remember, a significant change from high to low temperatures can lead to colder air in your mattress. Now, colder air tends to be relatively flatter, leading to your mattress becoming significantly flat overnight.

The solution is to ensure that the room temperature is kept warm throughout the night. Even if you want to switch off the main heating in your room, a portable heater can be useful.

Just place the heater in close proximity to your mattress to prevent the air inside going too cold. If this is done correctly, you should wake up to little or no air loss in your mattress

What if you are out there camping with an inflatable mattress? Temperatures can swing considerably in the night especially when you are sleeping in the woods.

Warm nights can easily turn cold within a short space of time. When this happens, you should consider heating your tent with an infrared space heater. This will help maintain warm air in your mattress so it doesn’t deflate uncontrollably.

Avoid Sitting On Your Air Mattress

Most of us are used to sitting on our regular beds whenever we get the chance to do so. With this habit engrained in us, we find ourselves sitting on airbeds whenever we feel like.

As a matter of fact, one of the worst things that can happen to your inflatable mattress is for you to sit on it. Sadly, there are so many homes where people turn these beds into sofas to catch big football or basketball games.

Sitting puts considerable pressure on different tiny parts of your mattress, leading to leakages and other considerable forms of damage to it.

Significant air loss even after full deflation becomes unavoidable as a result.

Check the Opening Nozzle

By their design, air is blown in and out of your mattress via the opening nozzle. If you sleep on your mattress fairly regularly then it is only a matter of time before the nozzle gets worn out.

This is especially common in cheap models manufactured for consumers with tight budgets.

Air starts to escape from airbeds more consistently when the opening nozzle begins to show signs of wear out. Even in the absence of punctures, a leaking nozzle alone can cause your mattress to deflate overnight.

If you have checked your mattress comprehensively for punctures and found none, it may be time to switch attention to the nozzle. Fortunately, duct taping it can prevent air loss and keep your mattress in shape throughout the night.

Folding Your Mattress Wrongly

Most people don’t pay too much attention to how their mattresses are folded after use. However, this can make or break it no matter how expensive it may be.

Whether you are traveling or simply need to fold your airbed for storage, it is important to fold it very well. Failure to do that consistently leads to the airbed developing minute leaks which get bigger over time.

Your mattress will start losing air inexplicably while you are scratching your head looking for the source of the leak.

In our experience, there are only a handful of scenarios more frustrating than waking up to a flat mattress every morning while you can’t find the source of the leak.

Mattresses With Separate Pumps

Buying a top-notch blowup bed with built-in pump can save you lots of headaches down the line. These mattresses are built with sophisticated technologies that eliminate most of the common issues.

Some models come with built-in neverFLAT technology which checks for air loss and tops up your mattress silently while you are sleeping.

It ensures little to no air loss overnight regardless of conditions such as room temperature. You therefore get to sleep buoyantly without being scared of waking up to a flat bed.

The Verdict

These are the common reasons why airbeds deflate overnight. Knowing them will help you understand what you need to do to ensure you wake up on a firm bed every morning.

Hopefully you will apply these tips to get a better sleeping experience no matter which brand of inflatable mattress you own.

Obviously, purchasing a well-engineered airbed model can save you the stress that comes with frequent overnight deflation.​
