Frequently asked questions
Do cotton mattress protectors prevent bed bugs?
Only full encasements with a bug-lock zipper prevent bed bugs. Cotton protectors must seal all seams; fitted sheets alone don't work.
Are cotton protectors cooler than polyester?
Yes, cotton is naturally more breathable than polyester. However, waterproof membranes can reduce airflow, so look for moisture-wicking technologies.
How often should I wash a cotton mattress protector?
Every 2-3 months or if soiled. Use mild detergent and avoid bleach; tumble dry on low to prevent shrinkage.
Can I use a cotton protector with a mattress topper?
Yes, but ensure it fits over both. Some protectors have deep pockets for thick setups.
What certifications should I look for?
OEKO-TEX Standard 100 ensures no harmful chemicals. CertiPUR-US applies to foam layers, not fabric, so focus on OEKO-TEX for cotton.
