What are Comforters Made of?

A comforter is a popular bed covering similar to a thick, fluffy blanket. It is a single-piece unit composed of a fabric shell surrounding soft, warm fill. Comforters usually lie on top of a flat sheet or blanket. They are often included in bedding sets and come in a variety of styles. Multiple layers make comforters warmer than traditional blankets.
Their outer shells typically consist of breathable material with a smooth, soft surface. Fuzzy and other textured options are also widely available. The inner fill can be a natural or synthetic material designed to insulate the sleeper. Patterned stitching helps hold the fill in place and prevent clumping.
Comforter Materials, Care, and Benefits
A comforter’s shell and fill materials affect its performance and longevity. While natural materials tend to be more effective temperature regulators, synthetic alternatives may be easier to clean and maintain. People who enjoy warm, fluffy bedding generally prefer a comforter over a thinner covering, such as a quilt.
Comforters are an easy way to add warmth and style to create your ideal bedroom. When used with a top sheet, they don’t need to be washed as often as a duvet cover. Care requirements vary widely depending on the materials, so it’s essential to check the manufacturer’s instructions.
Comforter Shells: What Are They, and Why Do They Matter?
Comforter shells are the fabric pouches that surround the fill, determining the outward appearance and feel. Understanding the specific kinds of shells can help you decide which is best for you.
Cotton Shells
Cotton is a natural plant fiber. It may be categorized as short-staple, long-staple, or extra-long staple depending on the length of the fibers.
-
How it feels: Shells that use longer-staple cotton varieties tend to be smooth, soft, and breathable. Feel also varies depending on the fabric’s weave. A percale shell is usually crisper and cooler, while a sateen shell is silkier and cozier.
-
How it performs: A cotton shell can improve the comforter’s airflow and simplify cleaning.
Silk Shells
Silk is a natural fiber made from the cocoons of silkworms and other insects. The fine silk threads are woven tightly together to form a fabric.
-
How it feels: This material is luxuriously smooth and cool to the touch. It can also feel slippery compared to other fabrics.
-
How it performs: Silk excels in temperature regulation, but its delicate nature requires extra care and attention. Due to the material’s slippery texture, preventing overnight shifting may be more challenging.
Wool Shells
Wool is a natural, hair-like fiber that comes primarily from sheep.
-
How it feels: Comforters with wool shells can feel soft or rough depending on their quality and construction. They often feel similar to a hefty blanket.
-
How it performs: Although warm in winter, wool also wicks away moisture for good year-round temperature regulation. You must maintain it carefully to prevent shrinkage and matting.
Eucalyptus Shells
Fabrics labeled as eucalyptus or bamboo typically consist of rayon or lyocell, which are made from processed wood pulp fibers.
-
How it feels: Eucalyptus- and bamboo-derived shells feel soft and silky, especially when paired with a sateen weave.
-
How it performs: Shells made from eucalyptus- or bamboo-derived fabrics are generally breathable, cool, and moisture-wicking, making them ideal for warmer climates. The smooth surface shouldn’t irritate sensitive skin.
Comforter Fills: What Are They, and Why Do They Matter?
A comforter’s fill material serves as insulation, playing a significant role in its overall quality and performance. Because each type of fill is unique, we’ll take a closer look at the most popular options.
Down Fills
Down is the soft, fluffy underlayer of feathers that insulates the bodies of waterfowl. Most comes from ducks or geese.
-
How it feels: Down comforters with a lower fill power tend to be light and breathable. Higher fill powers create warmer and heavier comforters.
-
How it performs: Because down is especially fluffy, it makes lighter and loftier comforters. Cleaning a down comforter requires extra care.
Down Alternative Fills
Down alternative is a synthetic material often made from polyester that imitates the fluffiness of down.
-
How it feels: While down alternative is often soft and warm, it generally doesn’t match the insulating capabilities of down. The fill quality and volume determine the breathability and warmth.
-
How it performs: While down alternative is not as durable as down, it is easy to clean and resistant to allergens.
Eucalyptus Fills
Eucalyptus fill consists of rayon or lyocell made from cellulose fibers derived from eucalyptus trees. Tencel is one of the most common brand names for this material.
-
How it feels: Comforters filled with rayon or lyocell derived from eucalyptus have a plush, down-like feel. The fill is an effective temperature regulator, wicking away moisture and heat.
-
How it performs: Eucalyptus-based rayon or lyocell comforters regulate temperatures to provide year-round comfort. They’re typically machine-washable.
Cotton Fills
Cotton is a natural plant fiber that is soft, breathable, and gentle on the skin.
-
How it feels: Cotton-filled comforters tend to be soft, light, and breathable. They work well for hot sleepers and individuals living in warm climates.
-
How it performs: Cotton isn’t as warm as many fill options, but it’s easy to clean and unlikely to trigger allergies.
Wool Fills
Wool is a natural fiber that is usually sheared from sheep. It acts as a natural insulator.
-
How it feels: Comforters with wool fill tend to be heavier and warmer, like a thick blanket. The material’s moisture-wicking and temperature-regulating properties help prevent overheating.
-
How it performs: Wool fill performs well in any climate, making it a popular choice for sleepers who want extra weight without excessive heat. While comforters with wool fill are often machine-washable, it is essential to take care to avoid damage.
What Is a Hypoallergenic Comforter?
If you have allergies or asthma, hypoallergenic comforters may be an excellent choice. Hypoallergenic bedding is designed to resist allergens such as mold, dust mites, and pollen.
Comforters that are labeled as “hypoallergenic” have usually been treated to reduce allergens or are made with materials that naturally repel these common triggers. Switching to hypoallergenic bedding can help reduce allergy symptoms and make it easier to breathe at night, leading to a more restful sleep.
Why Choose a Hypoallergenic Comforter?
Allergy sufferers can significantly benefit from hypoallergenic comforters, but they’re also a wise choice for anyone. Dust mites, mold, and other allergens can accumulate in bedding over time, regardless of whether you have allergies or not.
Choosing hypoallergenic comforters can help reduce common sleep environment triggers, leading to a more restful night’s sleep. If you’re looking for a bedding option that’s clean and free of allergens, a hypoallergenic comforter is a great choice.

What Is the Difference Between a Comforter and vs. Duvet?

When it comes to bedding, the differences between duvets and comforters aren't just cosmetic. This guide will help you understand how these bed coverings differ in structure, use, and maintenance so you can choose the right one for your home.
Structure: What's the Difference?
A duvet is defined by its removable cover. While comforters are designed with durable shells that don’t require an additional cover for protection, a duvet is typically filled with down or a synthetic alternative and encased in a duvet cover. This cover acts as an easy-to-clean, protective layer, allowing users to wash their duvet less frequently.
Warmth and Usage: When to Choose One Over the Other
Warmth is one of the most significant differences between comforters and duvets. Duvets tend to be thicker, fluffier, and warmer than comforters, making them more suitable for colder climates. These bed coverings are often filled with lofty materials, such as down, wool, or synthetic alternatives, that trap heat and insulate sleepers from the cold.
While some comforters are thicker and warmer than others, they tend to be cooler and less insulating. Therefore, they are more suitable for year-round use. Many sleepers find that comforters are best for warmer months and need to use an additional blanket for warmth in the winter.
Cleaning and Maintenance: How to Care for Duvets and Comforters
Both duvets and comforters are machine-washable, but the cleaning process can vary significantly. Comforters can be bulky and difficult to launder at home, and their care instructions depend on the materials used. Some owners prefer to use a washable duvet cover with their comforter for easier cleaning.
Duvets, on the other hand, are typically composed of two parts, the cover and the insert. The removable cover is generally machine-washable, which can reduce the need to clean the duvet itself. Depending on the materials and construction, some duvets are also machine washable, while others require dry cleaning or spot treatment.
Quick Comparison: Duvets vs. Comforters

Durability |
A comforter’s durability depends on its materials and the care it receives. Without a separate cover, it is more likely to get stained or wear out from repeated washing. |
A duvet’s cover can prolong its life by preventing damage and reducing the need for regular cleaning. Therefore, a duvet’s durability depends primarily on its materials and construction. |
Warmth & Loft |
Comforters tend to be thinner and cooler than duvets, making them more suitable for year-round use. Some people may need to use an additional blanket for warmth in the winter. |
Duvets are typically thicker and warmer than comforters. Their loft depends on the fill materials and maintenance. Over time, a duvet could flatten. You can restore the loft with occasional fluffing. |

What to Consider When Buying a Comforter?

When it comes to comforters, the fabric and stuffing have a significant impact on comfort, breathability, and overall performance. Most comforters on the market today are filled with either synthetic or natural materials. Natural materials include cotton, wool, and down, while synthetic options are typically made from polyester.
Natural vs. Synthetic Comforters
Both categories have their unique characteristics and advantages, so it’s worth considering your preferences before making a purchase. For example, down alternatives have a reputation for being very affordable and low-maintenance.
Natural materials like cotton and wool, on the other hand, tend to be more breathable and moisture-wicking, making them ideal for hot sleepers. Additionally, comforters filled with natural materials or organic fabrics are often more environmentally friendly and better suited for individuals with allergies.
Fill Power: The Comforter Quality Indicator
Fill power is a crucial measurement for any down-filled item. This term refers to the fluffiness of the down fill. More specifically, fill power indicates the amount of space one ounce of down occupies in the comforter.
Higher fill powers indicate more warmth, insulation, and fluffiness. You can get the right fill power for your needs by using the following recommendations:
-
400 or below: For summer use or for individuals who tend to overheat while sleeping.
-
400-600: A versatile fill power that can be used for comforters of all types and seasons.
-
600-800: A cozy down comforter that’s suitable for winter use or for those who tend to get cold at night.
-
800 and up: A comforter that’s extremely warm for chilly weather.
Size Matters: Choosing the Right Comforter Dimensions
There’s nothing like the feeling of being completely enveloped by your comforter as you settle into bed at night. Unfortunately, that sensation is ruined if your comforter isn’t quite big enough and you end up with a foot or hand jutting out.
Comforter size is a crucial factor to consider when purchasing a suitable comforter. To ensure that your comforter hangs adequately over the sides and foot of your bed, select one that is at least two inches larger than your mattress.
Budgeting for Your Comfort Needs
Comforters can become quite pricey quickly, so it’s essential to know your budget and the factors that affect comforter prices. A comforter’s price does not necessarily reflect its quality, even if it is more expensive.
It’s crucial to consider factors such as comforter materials, thread count, and other relevant details. Down substitute comforters are an excellent option for those seeking superior comfort on a tight budget. In addition to being much less expensive than down, down alternatives also require less maintenance.
Weather Considerations: Buying a Seasonal Comforter
Generally, summertime bedding should be made from lighter materials, such as cotton or silk, while wintertime comforters should be filled with heavier materials, like down or wool. Before selecting the material you want to purchase, you should consider the local weather and average temperature.
The comforter’s warmth is determined by its fill power, thickness, weight, and stuffing. The insulation is more effective the higher the fill power. If you reside in an area that experiences extreme cold, you may want to select comforters with high fill powers.
Thread Count: What It Means for Your Comforter
Thread count refers to the number of threads in a square inch of fabric. While a higher thread count does not always equate to better, the type of fiber is also significant, as well as the exact manner in which the fibers are woven. While textiles with a higher thread count are often of higher quality, they may feel stiff or heavy if the construction is subpar.
The thread count is a vital factor to take into account when buying a down comforter, but not so much for the fabric’s softness (unless you won’t be using a cover), but rather because greater thread counts efficiently trap down. A thread count of between 300 and 500 is good. To determine the thread count of the item you’re considering, check the label or product description.
Aesthetic Preferences: Personal Style and Comforters
In addition to performance characteristics, personal aesthetic preferences can also influence your satisfaction with a comforter. Comforters come in a variety of textures, patterns, and colors. With plenty of options available, you should be able to find a comforter that meets your needs and complements your decor.
