Glass Fibers vs. Fiberglass in Mattresses
Clarifying the difference, their uses, safety concerns, and chemical composition.
Is There a Difference?
Essentially, "glass fibers" and "fiberglass" refer to the same material. The terms are often used interchangeably, though "fiberglass" is more common in the United States.
Fiberglass is a composite material made of extremely fine fibers of glass. These fibers can be arranged in various ways: flattened into a sheet, randomly arranged, or woven into a fabric.
"The term 'fiberglass' sometimes refers to glass-reinforced plastic, where glass fibers strengthen a plastic material. This is often the case in mattresses, where fiberglass is used within a fabric layer."
Make Informed Choices
Weigh the benefits of fiberglass as a fire retardant against potential health risks. Consider mattresses using alternative fire retardants like wool.
