Protecting your mattress is essential for keeping it clean and performing at its best. A mattress protector adds a vital layer of defence against spills, allergens and everyday wear, helping maintain the life of your mattress. In this guide, you’ll learn what mattress protectors do, the types available, how to choose the right one, and how to use and care for it effectively.
What is a mattress protector?
Foam mattresses are crafted from materials such as memory foam, latex, or polyfoam. These materials contour to the body, offering pressure relief and comfort that can be beneficial for side sleepers and those seeking reduced motion transfer. A protector helps keep your mattress:
- Clean and hygienic
- Free from stains that may void warranties
- Protected from dust mites and allergens
- In better condition for longer
It’s important to note that a mattress protector is different from a mattress topper. A protector safeguards your mattress, while a topper changes the feel or firmness of your bed.
