Air mattresses are a convenient and comfortable option for camping, traveling, or hosting guests. However, many people have experienced the frustration of waking up on a deflated air mattress that feels like a waterbed.
Why do air mattresses deflate overnight, even if there is no visible hole or puncture? The answer is simple: the valve. No matter how well you seal it, the valve will always allow some air to escape over time. Some valves are better than others, but they all will leak eventually.
If you want to learn how to keep your air mattress from deflating, you have come to the right place.
I’m Jaden, and I have been using air mattress in my camping trips for over 12 years. I’ll explain the main reasons why air mattresses deflate and give you some practical tips on how to keep them from deflating.
By following his advice, you will be able to enjoy a more comfortable and restful sleep on your air mattress.
How Long Do Air Mattresses Last?
The lifespan of an air mattress depends on the quality of the mattress, the frequency of use, and how well it is cared for.
- With occasional use, a good-quality air mattress can last more than 5 years.
- With regular use, a good-quality air mattress can last for 2–5 years.
- If used every day, an air mattress may only last for 1-2 years.
Some signs that your air mattress is reaching the end of its life are:
- It deflates faster than usual, even if there is no visible leak or damage.
- It develops bulges, lumps, or holes that affect its comfort and stability.
- It loses its shape and becomes saggy or uneven.
- It makes loud noises when you move on it or inflate it.
- It smells bad or has mold or mildew on it.
Why is my air mattress deflating?
Your air mattress deflates because of four main reasons: the valve, the material, the seams, and the punctures.
- The valve lets some air out over time, especially if it is not closed properly or it is damaged.
- The material shrinks or stretches with temperature changes, which can affect the pressure inside the mattress.
- The seams weaken or break with use, especially if the mattress is overinflated or overloaded with weight. Read about How Much Weight Can An Air Mattress Hold?
- The punctures happen from sharp objects or pets, which can create small leaks that are hard to notice.
How do I prevent an air mattress from losing air?
There are several possible reasons why your air mattress might lose air overnight, such as temperature changes, weight distribution, air leaks, or over-inflation. Here are some tips to prevent or minimize this problem:
a) Make sure you inflate the mattress properly before use
Follow the manufacturer’s instructions and don’t overfill it. You can use an electric pump or a manual pump to inflate the mattress, but avoid using your mouth as it can introduce moisture and bacteria into the mattress.
b) Check the valve and make sure it is securely closed
The valve is the part where you insert the pump nozzle to inflate or deflate the mattress.
Sometimes, the valve can become loose or damaged and allow air to escape. You can tighten the valve by hand or use a wrench if needed. You can also apply some tape or glue around the valve to seal it better.
c) Inspect the mattress periodically for any holes or tears
To make sure that your mattress is not losing air due to a hidden leak, you can inflate it every once in a while and check for any signs of deflation.
If you find any, you can patch them up with a repair kit or some duct tape. You can also use some soapy water to detect any leaks by spraying it on the mattress and looking for bubbles.
If you see any, mark the spot and dry it before applying the patch.
d) Place the mattress on a smooth and flat surface
Avoid putting it on rough or uneven surfaces that can cause punctures or abrasions. You can also use a mattress protector or a sheet to cover the mattress and protect it from dirt and dust.
e) Adjust the room temperature and humidity
Extreme cold or heat can affect the air pressure inside the mattress and cause it to deflate.
Try to keep the room temperature between 18°C and 24°C (64°F and 75°F) and avoid direct sunlight or heat sources.
You can also use a humidifier or a dehumidifier to control the moisture level in the room.
f) Distribute your weight evenly on the mattress
Don’t sit or stand on the edge of the mattress as it can cause more stress on the seams and lead to air loss.
Try to sleep in the center of the mattress and avoid bouncing or jumping on it.
g) Deflate and store the mattress properly when not in use
Don’t leave the mattress inflated for too long as it can stretch out the material and reduce its durability.
Deflate the mattress by opening the valve and squeezing out the air. Fold or roll up the mattress neatly and store it in a cool and dry place away from sharp objects.
