Why Does My Mattress Bulge on One Side?

Bulging on one side of your air mattress is due to some reasons, such as misuse and mishandling. Let us discuss some common reasons in detail.

1. Over-Inflation

Overinflation is the most significant reason for bulge formation. When you inflate your air mattress beyond its limit affects its seams. The presence of more air causes the stretching and unwrapping of the seams. As a result, it starts losing its elasticity. A point comes when it loses its elasticity and deforms. The deformation leads to a bulge on the side of the mattress.

The bulge not only makes the mattress look bad but also feels uncomfortable. You cannot sleep on the bulge side of the air mattress at any cost. So, it is good to avoid over-inflation of the air mattress. Always follow the manufacturer’s instructions to prevent inflation.

2. Overweight

You can find a variety of air mattresses in the market. They vary in their qualities, price ranges, and weight limits. Before you use an air mattress, you must know its capacity to withstand the weight. So that if you exceed the weight limit of your mattress, you will only end up disappointed.

Overweighting makes the seams of the air mattress weak. When you keep putting overweight on your mattress, the seams fail to keep their shape. So, the bulges are formed at the seam areas that cause severe irritation during bedtime. It can also cause body aches. Putting the weight according to the weight-bearing capacity can prevent bulge formation. It also ensures its durability.

3. Effect of Aging

It may seem strange, but aging affects the mattress. A more significant difference exists between a new and an old air mattress. Aging affects the effectiveness of the mattress. A new one has stronger seams than one you have used for years. A typical air mattress may get bubbles or bulge after regular use for two years.

If you are using your air mattress, follow the manufacturer’s instructions. Then aging is the only reason behind bulge formation. The seams become weaker with time which causes the formation of bubbles. If you are facing the same issue, setting your seam is better. Investing in a new air mattress is better if the bulging problem occurs.

It is a clear fact that high-quality products are found at the lowest price and can cause damage. In contrast, high-quality products are found at expensive rates but provide long-term benefits.

The same is the case with air mattresses. High-quality air mattresses offer high resistance against wear. It does not form bulges. So their seams are more robust than those manufactured with poor-quality materials. The seams of the mattresses made with cheap material undergo stretching and deformation. Even when they are subjected to a bit of mishandling. Thus, they are more susceptible to bulge and bubble formation.
