If you wake up sweating in the middle of the night, your mattress might be trapping heat. A cooling mattress topper can drop your sleep temperature by several degrees — without buying a new mattress.
Here are the best cooling mattress toppers on Amazon right now.
Why Sleep Temperature Matters
Your core body temperature needs to drop 1-2 degrees to initiate and maintain deep sleep. If your mattress retains heat, this process is disrupted — causing you to wake up hot, sweaty, and unrested.
This is especially common with:
- Memory foam mattresses (notorious heat trappers)
- Hot climates
- People who naturally sleep hot
- Couples sharing a bed
What to Look for in a Cooling Mattress Topper
- Material: Gel-infused foam, latex, or wool cool better than regular foam
- Breathability: Open-cell foam and copper-infused options allow airflow
- Thickness: 2-3 inches is ideal for most people
- Cover: Look for Tencel, bamboo, or other moisture-wicking fabrics
- Size: Make sure it matches your mattress size
