Duvet vs. Comforter:
How To Spot the Differences


Written by David Rubin

Expert Tested

Duvets and comforters have similar functions, so people often assume they’re one and the same. Both are designed with coziness in mind, but they differ in feel, loft, and care. There’s even variation within each type depending on the manufacturer and materials.

What Is a Duvet?

Unlike a comforter, a duvet includes two components: a cover and an insert. The French word “duvet” literally translates to down, referencing the fine feathers that were originally used as fill. Today, inserts can contain any number of natural or synthetic fibers, including down, feathers, wool, cotton, and down alternative. A thin cotton or polyester shell usually encases the fill.

A duvet insert generally has a notable loft, giving it a plush, comfy feel. The insert is designed for use with a duvet cover, which helps protect it from stains and general wear. Covers come in a variety of designs and materials, including cotton, linen, flannel, and silk. A duvet cover typically attaches to the insert via zippers, buttons, or ties.

How Do You Use a Duvet Cover?

Because duvets have removable inserts, they are very versatile for regulating sleep temperature. Inserts come with different levels of loft and insulation, so you can change them depending on the season. Lightweight cotton inserts are popular during the summer months, while thicker down options help keep sleepers warm in colder seasons.

A duvet’s two-part system also simplifies cleaning. While most inserts can be spot-treated or dry-cleaned, duvet covers are usually machine-washable. Always refer to manufacturer guidelines before washing any part of your duvet.

What Is a Comforter?

A comforter is essentially the American counterpart to the European duvet. However, a comforter has a built-in cover. This simplicity appeals to many people. Similar to a duvet insert, most comforter fill consists of cotton, polyester, wool, down, feather, or down alternative. Comforters come in a range of price-points for varying budgets.

Can You Insert a Comforter Into a Duvet Cover?

Even though a comforter is designed as a standalone solution, some people use a duvet cover for extra protection. That said, comforters tend to be larger than duvet inserts, so inserting a comforter into a duvet cover isn’t always possible.

On the other hand, you should almost always protect your duvet insert with a cover to shield against stains and wear. However, a duvet insert that is advertised as a combination insert and comforter may not require a cover.

Are Duvets and Comforters Sized Differently?

Most comforters are larger than duvets, so they tend to hang over the sides of a bed more. Because of this, you should take your bed frame style and mattress thickness into consideration when deciding between a comforter and a duvet.

Bed Frame: Bed frames come in different styles, affecting the way a duvet or comforter fits. A large comforter might interfere with a taller footboard or side rails, in which case a smaller duvet might be more appropriate. On the other hand, a high-profile frame often pairs well with a comforter that generously covers all sides of the bed.

Mattress Thickness: Mattress thickness should also inform the type of bedding you choose. Most duvets comfortably accommodate low-profile models and those of average height. However, a comforter may be more appropriate for high-profile mattresses, especially if you want the coverage to extend beyond the edge of the bed.

Duvet vs. Comforter: Which Is Best for You?

As with most products, duvets and comforters both have potential strengths and weaknesses. We highlight important considerations so that you can determine the best option for your needs.

Breakdown of Duvets and Comforters

Bed Covering


A plush insert paired with a protective cover.

  • Extra plush and cozy feel
  • Adaptable to different climates and seasons by swapping out the insert
  • Convenient cleaning
  • Inserts may be tricky to change
  • Covers are usually sold separately
  • Insert may shift over time


A single piece consisting of insulating fill and a built-in cover.

  • Simple, one-piece design
  • Usually large enough to suit taller beds
  • Available in a range of designs and price-points
  • May be difficult to clean
  • Less versatile
  • May flatten over time depending on the fill material

How Do They Compare in Performance and Construction?

While duvets and comforters have similar functions, they vary in performance and construction:

Duvet vs. Comforter



A duvet’s durability ultimately comes down to its quality of materials, craftsmanship, and care. A shell with a minimum thread count of 300 is more likely to withstand normal wear and tear when protected by an appropriate cover. High-quality fill can also resist clumping, though it may require occasional fluffing.

A comforter’s longevity depends largely on the materials and maintenance. Staining and other visible signs of wear may be problematic since most comforters don’t have protective covers. Overwashing can also prematurely degrade the fill, resulting in a flatter comforter.

Ease of Use

Attaching the duvet cover to the insert can be finicky. Ties or snaps sometimes detach too easily, causing the insert to bunch. However, the benefits of easy cleaning usually outweigh any mild frustrations caused by the assembly.

Since a comforter is just one piece, no special setup or attachments are required. Sleepers don’t have to worry about interior components loosening from the cover.

Cleaning and Care

Cleaning guidelines depend on the duvet’s materials and construction. Most duvet covers are machine-washable. Some inserts can also be washed in a machine, but spot treating or dry cleaning generally helps protect the fill. Always follow the manufacturer’s care instructions for the best results.

Your Sense of Style

Duvets are very versatile since you can trade out the cover to change the look. Duvet covers come in countless colors and patterns, so shoppers should have no trouble finding an option to suit their preferred aesthetic.

Comforters come in a variety of colors and styles because they’re designed to be used without covers. Changing the look generally requires buying a new comforter, which typically costs more than replacing a cover.

Is Either a Budget-Friendly Option?

Duvets and comforters range in price from economical to luxurious. The cost usually increases with higher-quality materials and superior craftsmanship. Additionally, models made from natural materials are often pricier than those made from synthetic alternatives.

Most duvet inserts are between $50 and $300, while covers typically range from $30 to $150. Comforters generally start around $75 and reach upward of $150. However, you won’t need to purchase a separate cover if you opt for a comforter.

Which Option Is Warmer for the Winter Months?

Either a duvet or comforter can insulate well in winter depending on its fill and loft. For example, thinner cotton models are often intended for summer use. Down-filled duvets and comforters are typically warmer, making them popular for the fall or winter.

In general, duvets have an edge over comforters when it comes to temperature control since you can change the insert based on the season.
