Comforters don’t receive the attention that they deserve. Most customers shopping for beddings usually only care about a queen mattress, bed pillows, or weighted blankets and forget that comforters are also an essential element if you want to have a comfy bed.

And the quality of a high-quality comforter goes beyond the outer comforter cover or the bedding brand.

It’s the comforter fill that determines the comfort, fluffiness, and the level of coolness or warmth you get from your bed. So it’s a must that you should pay close attention to the inside fabric too, like the best comforter materials below.

Best Materials for Comforters

Cotton – The Most Breathable

It should come to no one’s surprise that cotton is the first material listed here.

It’s one of the popular types of fill for bedding comforters, especially for those who want to stay cool. If you’re in search of a summer comforter or where you live has a hot climate, or you’re prone to sweating or overheating at night, there is easily the best option for you.

Made from breathable natural fiber, cotton is a comfortable material and can absorb moisture from your body and stay cool against your skin. This is also a versatile material that you can use in the winter as well when it can keep you warm and cozy at night.

Unlike other filling materials, its quality doesn’t drop as it ages. In fact, cotton-filled comforters will become softer overtime. It also doesn’t require much time and effort from you to take care of cotton as washing or removing stains are simple to do at home.

Cotton comforters come in a wide range of prices – suitable for both budget-conscious customers and those who want high-quality products.

But if you don’t know much about cotton and comforters, it’s almost impossible to tell whether a product has good quality or not. So it’s a bit ironic that this advantage of cotton sometimes puts off a lot of new customers too.

The biggest issue with cotton comforters is that when they aren’t washed and dried properly, wrinkles are likely to happen. They also wear out and shrink more easily than those made from polyester.


  • More moisture and heat resistant than other materials
  • More comfortable and softer than synthetic fabrics in general
  • Become softer after several washes
  • Easy to clean dirt and stains
  • Cotton comforters pill less than those made from synthetic materials.


  • High-grade cotton is more expensive than synthetic materials
  • Tend to tear and fade after a few washes
  • Machine washable
  • Not compatible with all detergents
  • Have wrinkles easily

Polyester – For Budget Choice

If your budget is limited, polyester fill is not a bad alternative comforter choice to get a good night’s sleep. It provides a great value for your money: it doesn’t easily lose its shape, is easy to maintain, and lasts longer than other materials.

A polyester comforter works great with a duvet cover if you want to stay warm in the winter or a cold climate as it traps a lot of heat and moisture. But this also means you can feel uncomfortable if it gets warmer.

Unlike cotton, polyester doesn’t develop wrinkles. You can take care of your polyester comforters at home easily with your washing machine and dryer. But they absorb more moisture and oil while you can’t remove stains as easily as cotton comforters.

On top of that, beddings with polyester fill tend to pill when after a few washes – a day-and-night difference between it and natural materials. People with allergies or skin problems may don’t like it either as polyester is more irritating to the skin than other fabrics.


  • Low price
  • Easy to wash and dry
  • Great for cold weather
  • Durable and lightweight
  • Wrinkle- and water-resistant


  • Low durability
  • Prone to static and pilling
  • May soak up grease and oil, causing stains
  • Not suitable for sensitive skin

Wool – High-grade & Warmest Material for Cold Weather

Like cotton, wool is also a natural fiber that has a high degree of breathability, which helps you moderate your body temperature. It doesn’t trap moisture and humidity like other unbreathable fabrics.

Wool filling is also hypoallergenic and resists dust mites pretty well, making it an ideal choice for those with sensitive skin.

Wool is soft and fluffy with a high level of fill power. Although you can totally use it in the summer, wool is mainly material for cold weather. It can keep you warm while absorbing moisture, so you don’t feel uncomfortable and sweaty. On top of that, it’s even flame retardant.

But you usually must pay a higher price to get silk comforters made from a reputable bedding brand.

They are also fragile and not easy to wash at home like those made from polyester and cotton. To take care of wool comforters, you must use warm water with gentle detergent and avoid harsh chemicals as much as possible.


  • Durable
  • Naturally hypoallergenic
  • Extremely breathable, drawing moisture away from your skin
  • Can keep you warm in the winter
  • Fire-resistant


  • Expensive
  • Difficult to wash
  • Not a good choice for hot sleepers

Silk – Top Choice for All Seasons

Silk, often found on luxurious beds, is one of the lightest and most comfortable bedding materials with a low number of thread counts.

Like wool, silk filling is also a popular choice for sensitive skin thanks to the natural hypoallergenic capability. Plus, silk comforters are breathable and help maintain your body temperature.

But unlike wool, you can use these lightweight comforters all year round without worrying about overheating. In fact, they can keep you cool during the summer. And this is without a doubt the coolest comforter material in all of four.

Silk shares the same weak points of wool: beddings made from silk are more expensive and harder to take care of than other fabrics. You can’t machine-wash it to deal with dirt and stains. Instead, you can only wipe them down with a cloth.


  • Lightweight
  • Can be used as an all-season comforter
  • Highly breathable
  • Hypoallergenic and resistant to dust mites


  • Expensive
  • Too delicate to wash normally at home

Final words

The filling material inside plays a larger role in comfy bedding than you might realize, but there is no one-size-fits-all option here. The best material for comforters depends on how much you can spend, the climate, and what kind of sleeper you are. As long as you figure out what is needed, finding the right comforter will be a lot easier.
