Frequently asked questions
Do I need a mattress protector for a Purple mattress?

Can a mattress protector affect the feel of a Purple mattress?
Most protectors are designed to be thin and noiseless, minimizing impact on the Purple feel. Look for breathable, stretchy fabrics to avoid altering pressure relief. Owners report that cotton or bamboo protectors work well.
How do I choose the right size protector for my Purple mattress?
Purple mattresses come in standard thicknesses, but some models are thicker (e.g., Purple Premier up to 13 inches). Ensure the protector’s pocket depth matches your mattress height. Most protectors fit up to 18 inches, suitable for all Purple models.
Are mattress protectors machine washable?
Yes, all protectors listed are machine washable. Use cold water and gentle cycle, then tumble dry low. Avoid bleach or fabric softeners to maintain waterproof integrity.
