Q: Why should I use mattress and pillow protectors?
A: In a perfect world, your sheets alone would be enough to protect your bed. Fortunately, we have mattress pads and pillow protectors, which are the necessary layer between you and your mattress & pillows. Unprotected, they are prone to yellowing and odours caused by natural perspiration and oils. A protector will significantly extend their lifespan while protecting against dust mites. Remember, you basically never wash your mattress or pillows, that's why you need to keep them clean.
