Frequently asked questions
What makes a memory foam topper cooling?
Cooling memory foam toppers use gel infusions, open-cell foam, phase-change materials, or breathable covers to dissipate heat. Natural latex also sleeps cooler due to its open-cell structure that promotes airflow.
How thick should a cooling memory foam topper be?
For cooling purposes, 2-3 inches is sufficient. Thicker toppers (4 inches) may retain more heat unless they use advanced cooling technology. Choose thickness based on your comfort preference and mattress condition.
Will a memory foam topper sleep cooler than a mattress?
Yes, if the topper uses cooling materials like gel or latex. Many toppers are designed with better airflow than the foam layers in mattresses, and they can be replaced if they wear out.
How do I clean a cooling memory foam topper?
Most toppers have removable covers that can be machine washed. Spot clean the foam with mild detergent and water, then air dry. Avoid soaking foam to prevent mold or loss of cooling properties.
What certifications should I look for in a cooling topper?
Look for CertiPUR-US (safe foam) and OEKO-TEX (non-toxic). For natural toppers, USDA Organic and Greenguard Gold indicate low chemical emissions.
