Frequently asked questions
What certifications should I look for in a 100% cotton mattress?
Look for GOTS (Global Organic Textile Standard) for the cotton cover, GOLS for latex, and CertiPUR-US for foams. OEKO-TEX Standard 100 ensures no harmful substances, and GREENGUARD Gold indicates low chemical emissions.
Are 100% cotton mattresses cooler than synthetic ones?
Yes, cotton is a breathable natural fiber that helps wick moisture and promote airflow. However, the overall cooling performance also depends on the mattress core materials like latex or innerspring coils.
How long does a 100% cotton mattress typically last?
A quality organic cotton mattress with latex or durable coils can last 8-12 years with proper care. Owners report that natural latex tends to outlast synthetic foams without sagging.
Can I flip a 100% cotton mattress?
It depends on the model. Many organic cotton mattresses are flippable if they are designed without a pillow top. Always check the manufacturer's instructions before flipping.
Do 100% cotton mattresses contain fire retardants?
Most use natural fire barriers like wool or cotton batting instead of chemical flame retardants. Wool is a common natural fire resistant material used in organic mattresses.
