A duvet is essentially a comforter that is meant to have a cover.  Originally, the term duvet, was defined as a “Down filled quilt, often with a removable cover.” The duvet is inserted into the cover, thus the term duvet insert.

The word duvet comes from the French and refers to down or bird feathers which is what early comforters were made from. In our modern marketplace, duvets are made from all kinds of different materials that include down, but also include wool, cotton, and down alternative. You can technically use a duvet without the cover, but for ease of care, the cover is a great asset. Check out our top picks for best duvet inserts.

What is a Duvet Insert?

A duvet insert is a blanket you use on the bed similar to a comforter but it is flatter and typically filled with synthetic fibers, down, feathers, or wool. Duvets themselves are a type of insert that you use with a duvet cover. The style of these alternatives to comforters allow you to easily maintain the cleaning on your bedding. You simply remove the duvet cover and wash it, much easier than washing a large, bulky comforter.

Pros of a duvet

  • Easy cleaning
  • Cheaper than a comforter
  • Easily change styles by switching out the cover

Cons of a duvet

  • Changing covers can be tricky
  • Can shift in the cover and get lumpy
  • Yet another bedding piece to purchase (but it’s cheaper)

How to Choose the Best Duvet Insert

  • Fill Material: Consider which fill material is best for you. Popular options include goose down, duck down, down alternative, wool, cotton, and silk. Down options are softer, cotton is very breathable, wool will keep you warm in cool weather, and silk is great for summer months.
  • Fill Power: Fill power measures the amount of space that one ounce of filling takes up. Higher fill power duvets are more thick and insulating, meaning they provide more warmth, durability, and loft. Lower fill power duvets are more lightweight. Generally fill power ranges between 400-800.
  • Design of the stitch: The stitching of your duvet can help you understand how well it will stay in place. Common stitching types include box-stitch, channel stitching, gusset stitching, and baffle-box stitching. Baffle-stitched and gusset-stitched duvets have more loft. Channel stitching does not keep a duvet in place as well. Box-stitching keeps a duvet secure, but does not retain as much loft as other types of stitching.
  • Size: What size is your bed? Duvets are typically available in the same sizes as beds, ranging from twin to California king sizes.
  • Price: What’s your budget? Duvets can be anywhere between $100 to $1,000, so be sure you define your budget before shopping.

How to Care for Your Duvet Insert

The first thing to note about care is that duvet inserts are meant to be covered. This allows you to remove and wash the cover on a regular basis and only clean the insert periodically. Recommendations can be from every 6 months to every 5 years depending on conditions. Duvets are large items that can require commercial size washers or dry cleaning, so the cover makes maintaining them far easier. 

  1. Start by Reading the Instructions: Your duvet insert will have specific instructions that will include washing or dry cleaning, types of detergent, dry settings and more. If you follow the instructions, it should keep your insert in good shape. 
  2. Have a Schedule: You may only need to wash your comforter every year, but you may want to do it more often or less often depending on how much work it is and if it really needs it. It helps to keep track of when you last washed it, so times don’t get away from you. If you have a good cover, you can wash that every couple of weeks, and the duvet will remain protected. 
  3. Washer Size: Most at home machines will easily hold a queen-size duvet. For larger sizes or if you have a small washer, you may need to find a commercial machine, take it to the cleaners, or wash in the tub. 
  4. Detergent: Especially if you bought an organic comforter, but even if you didn’t, you may want to buy some kind of natural soap. Chemical or synthetic laundry soaps shorten the life of the duvet and add in toxins that many manufacturers are working to keep out of their products. Natural soaps are better for the environment and safer for you to breathe while sleeping. 
  5. Dryer Balls: These are especially helpful for down and down alternative to keep the feather or fibers from drying in clumps. The dryer balls bounce around in the dryer and break up the clumps that occurred from washing. Try clean tennis balls or purchase dryer balls which come in felted wool, plastic, and other assorted materials.
