Mold Growth in Beds

First, it's important to know that mold growth in beds is rare and there are many ways to avoid mold growth.

Mold spores travel from outside to the indoors through open windows, doors, ducts, air conditioners or from your body. These spores can land on any surface, including beds. If the spores do not have enough food and moisture to grow and multiply into mold, they usually die within six months. However, there are rare circumstances in which enough moisture and food exist on a bed to grow mold.


Mold is living fungi that occurs in nature in large quantities. These fungi reproduce by releasing spores into the air, which settle on surfaces. If mold spores settle on organic or contaminated surfaces when other conditions of temperature, humidity, shade or darkness, and oxygen supply are conducive, they may germinate and develop new colonies of mold.

Spotting Mold in Beds

Usually, mold is first detected by a musty odor. In the rare case that a bed does have mold, the portion of a mattress affected often is small — generally less than six square inches. Bed mold often goes undetected because of the enclosed construction of traditional innerspring mattresses. A benefit of the Sleep Number® bed is that the mattress can be easily unzipped, which allows a consumer to address the issue in the rare case mold is present. That's not the case with traditional innerspring mattresses.

Mold Growth Prevention

To minimize the formation of mold, most mattress companies treat their products with an antimicrobial agent. You also can help ensure your bed is at lowered risk for mold growth by doing such things as keeping humidity levels under 50 percent and cleaning your bed, bedding and bedroom on a regular basis
