What to Look for in a Cooling Comforter

1. Cooling Technology

The best cooling comforter uses signature technology — which consists of a blend of fibers and materials, such as polyester, Tencel, and cotton — to regulate body temperature.

So how does cooling technology work exactly? Well, when your skin's temperature increases, the material absorbs the excess heat to prevent you from overheating. When you get cold, the material restores heat back to your body.

2. Materials and Breathability

When you're on the hunt for a cooling comforter, it's best to "avoid too bulky or heavy comforters," which can trap heat, Dr. Vyas says.

Cooling comforters are usually made of breathable materials and fibers, such as polyester, Tencel and cotton. These are known for absorbing heat, which can help decrease your overall body temperature.

Additionally, if you have sensitive skin or are prone to breakouts, Dr. Vyas says to "look for fills without too many synthetic ingredients." (Think: polyester.)

If a comforter is synthetic and chemical-free, it will be labeled Oeko-Tex 100 certified.

3. Weight

The best cooling comforters are usually lightweight, which varies by brand. If your comforter is weighted, it will weigh between 10 and 25 pounds. Follow the brand's instructions for choosing a blanket weight.

4. Size

Cooling comforters come in many sizes, often from twin all the way to California king, so make sure to choose one that fits your bed's size. For example, if you have a queen bed, choose a queen-sized cooling comforter.

5. Price

The majority of quality-made cooling comforters cost between $100 and $200. If cost is a concern, there are some affordable options under $100, including the COHOME King 2100 Series Cooling Comforter and the Luna Cooling Bamboo Weighted Blanket.
