What Makes a Mattress Protector “Cooling”? (Reddit’s Education Thread)

Before diving into specific products, let’s understand what Reddit users have learned about cooling technology. A common misconception is that “cooling” simply means “breathable.” While breathability is important, true cooling protectors go beyond.

According to multiple Reddit threads, effective cooling protectors typically feature:

• Phase-change materials that actively absorb and dissipate body heat
• GlacioTex or similar technologies that create a cool-to-the-touch surface
• Specialized weave patterns that enhance airflow without compromising waterproofing
• Moisture-wicking properties that draw sweat away from the body

One popular Reddit user in r/Mattress explained: “A good cooling protector doesn’t just feel cool at first touch—it maintains temperature regulation throughout the night. That’s the difference between gimmicks and genuine cooling technology.”

Many Reddit users report disappointment with bamboo-only protectors, which feel cool initially but trap heat as the night progresses. Instead, they recommend products that combine multiple cooling technologies.
