Why Do Air Mattresses Have Bumps?

(Last Updated On: June 17, 2023)

Air mattresses are one of the most popular types of bedding products because they offer comfort, versatility, and affordability. Air mattresses are not only popular among adults but also among children and the elderly. But some people may get annoyed by the bumps on an air mattress. And wonder why that is.

In this article, you will get the answer to the question – why do air mattresses have bumps?  

There are various reasons why air mattresses have bumps. These bumps are there to mainly keep the air mattress in place and hold it together, balance the weight of people sleeping on it, provide some back support, and prevent you from feeling like you are sinking into the bed.

To Keep The Air Mattress In Place 

Air mattresses have bumps by design. The design of the air mattress allows the air to keep the mattress ‘in place’ by using a network of tubes that hold the two sides together. It’s a bit like putting a bunch of balloons in a jar.

When the air inside the tubes expands, it pushes against the tube’s inner walls, keeping the mattress in place. The mattress is still flexible, though, so it can move and settle a little with the person’s weight

Without these bumps, the air mattress would not be able to stay in the rectangular shape that a mattress is. And it would instead become a balloon which, I’m sure you can imagine, is not comfortable at all. Not to mention, impossible to sleep on. 

To Balance The Weight

The bumps on the air mattress help distribute the weight evenly of the person who is sleeping on it. Since the mattress has nothing but air in it, without the mattress, the person would get the feeling of sinking into it.

Depending on the air volume inside the mattress, it can either feel too hard or too soft. That is why the bumps are there to balance it out. 

When air mattresses are compressed, they form a solid platform for your body to rest on. While sleeping on an air mattress, you will experience the gentle pressure of air beneath your body. As you sleep, the air will allow you to sink into the mattress a little and feel comfortable and supported.

To Provide Minor Back Support

It’s normal for an air mattress to have some sort of bump or ridges to provide some minor back support. If you have been sleeping on a standard mattress, you may be surprised at how good an air mattress can feel.

This is because it offers you support similar to that of a traditional mattress, but without the feeling of sinking into a hard surface.

Without any proper back support, you can end up having back pain.

To Prevent You From Sinking Into The Bed

The bumps help the air mattress not to mold around you when you lie on it.

Unlike a traditional mattress which is firm enough to not let you sink into it, air mattresses do not have a thick foam layer. Due to the lack of thick foam layer, air mattress do not have good insulation either. 

But because of these bumps, you do not have to worry about your air mattress molding around you.
