Why is my mattress yellow?


If you’ve noticed that your mattress has turned yellow over time, you may be wondering why this has happened. A yellow mattress can be unsightly and may make you question the cleanliness and quality of your bedding. In this article, we will explore the various reasons why a mattress can turn yellow and what you can do to prevent or address this issue.

Sweat and Body Oils

Sweat and body oils are one of the most common culprits behind a yellowing mattress. When we sleep, our bodies naturally release sweat and oils, which can seep into the mattress fabric. Over time, these substances can oxidize and cause discoloration, resulting in a yellow appearance. This is especially true if you tend to sweat heavily during sleep or if you do not regularly clean your mattress.

Stains and Spills

Another reason for a yellow mattress is stains and spills. Accidental spills of beverages, food, or other liquids can leave behind stains that can be difficult to remove. If these stains are not promptly cleaned, they can penetrate the mattress fabric and cause discoloration. Additionally, bodily fluids such as urine or vomit can also lead to yellowing if not properly cleaned.

Mold and Mildew

Mold and mildew can thrive in environments with high humidity or moisture levels. If your mattress is exposed to moisture due to factors like excessive sweating, spills, or a damp sleeping environment, it can create a breeding ground for mold and mildew. These fungi can cause yellow stains and also contribute to an unpleasant odor. It is essential to keep your mattress dry and well-ventilated to prevent mold and mildew growth.

Age and Degradation

Over time, mattresses naturally age and degrade. The materials used in mattresses, such as foam or fabric, can break down and deteriorate. As a result, the mattress may start to yellow as it loses its original color and vibrancy. This process is more common in older mattresses that have been used for many years without proper care or maintenance.

Prevention and Maintenance

To prevent or address a yellowing mattress, there are several steps you can take:

1. Regular cleaning: Vacuum your mattress regularly to remove dust, dead skin cells, and other debris. Use a mattress cleaner or a mixture of mild detergent and water to spot clean stains.

2. Mattress protectors: Consider using a mattress protector to create a barrier between your body and the mattress. This can help prevent sweat, oils, and spills from seeping into the mattress fabric.

3. Proper ventilation: Ensure your bedroom is well-ventilated to reduce moisture levels. Use a dehumidifier if necessary, especially in humid climates.

4. Rotate and flip: Rotate and flip your mattress regularly to distribute wear and tear evenly. This can help prolong its lifespan and prevent excessive yellowing in specific areas.

5. Professional cleaning: If your mattress has significant stains or discoloration, consider hiring a professional mattress cleaning service. They have specialized equipment and techniques to deep clean and remove stubborn stains.


A yellow mattress can be a result of various factors, including sweat and body oils, stains and spills, mold and mildew, as well as natural aging and degradation. By practicing proper maintenance and prevention methods, such as regular cleaning, using mattress protectors, ensuring proper ventilation, and seeking professional cleaning when necessary, you can keep your mattress looking clean and fresh for a longer time.
