Sometimes confused with comforters and duvet covers, a duvet insert — or simply “duvet” — is a type of bedding designed to be protected by a removable cover, known as a duvet cover. By comparison, a comforter is a blanket that is typically meant to function as a single unit without requiring a separate casing.
However, both comforters and duvets ultimately perform the same function: to cover and keep you warm during the night.
In this guide, we will explore duvet inserts specifically. When choosing a duvet insert, there are a number of factors to consider, including filling and shell materials, construction, and size. Read on for expert guidance on how to choose the best duvet insert, including reviews on top models for 2020 and buying advice on selecting the duvet with the best features for your needs.
Our Editor’s Pick, the Brooklinen Down Comforter uses down that is ethically sourced from Hutterite farms Northwestern Canada.

Duvet inserts come with many benefits, including the ease of cleaning and style variety afforded by their removable cover. Duvets also come in a variety of warmths, allowing you to choose one that suits your climate and personal preferences. If you are considering purchasing a duvet insert for your bed, our buying guide will help you select the best duvet insert for your needs.
We’ll walk you through how to choose a duvet insert based on fill material, fill power, and shell material. Then, we’ll discuss the different types of stitching typically seen in duvet inserts, in addition to the different sizes and their pricing. Finally, we’ll touch on the process of cleaning your duvet insert before weighing the benefits of choosing a duvet insert over a comforter.
Frequently confused with comforters, duvet inserts feature slight — but important — differences from their comforter cousins. Originating in Europe, duvet inserts or simply “duvets” were traditionally stuffed with down. Today, you’ll find down duvet inserts stuffed with down along with those stuffed with feathers and synthetic fibers. Duvets are typically white or off white in color.
Comforters are also similarly often filled with down, feathers, and synthetic fibers. The key difference between the two types of bedding lies in the necessity — or lack thereof — for a protective cover. Duvets are designed to be used with a removable casing or “duvet cover” to protect them from body oil, spills, and damage.
Comforters, on the other hand, are designed to be used without a cover and may require a top sheet to act as a hygienic barrier between your body and the bedding. Even though it is not required, some sleepers may opt to use a duvet cover with their comforter to protect it as they would a duvet.
When it comes to choosing a duvet insert, there are several principal factors to consider, including fill material, fill power, shell material, and construction. The following sections will help you with selecting each one.
The fill material is the “stuffing” inside the duvet insert. Below, we explore the most common fill materials.
When searching for a duvet insert, you will likely encounter the term “fill power, or the measurement of the amount of space one ounce of filling will occupy. Fill power essentially tells you the duvet’s fluffiness; a higher fill power indicates a thicker and more insulating product with a higher loft. It’s also worth noting that in addition to providing more warmth, higher fill power means larger, more durable down clusters that tend to maintain their loft and firmness for longer.
We’ve included a general guide to duvet insert fill power options below:
Although duvet inserts are kept beneath protective covers, their shell material is still worth considering. Here are some of the most common shell materials and their benefits and drawbacks:
Construction or stitch design may play a part in your decision to choose a duvet insert. Read on to learn the pros and cons of common stitching:
Duvet inserts typically come in sizes that correspond to bed sizes, including Twin/Twin XL, Double/Full, Queen, King, California King. If you don’t have a bedskirt or prefer some overhang, however, consider ordering a duvet that is one size above your mattress size.
Duvet inserts should be washed every two to three months. Before washing, be sure to check the label: many materials, including down and feather, may require dry cleaning.
When machine-washing your duvet, treat stains first by shaking the filling away from the dirty spot and hand washing the stain. If you are having trouble fitting a larger duvet into a conventional machine, ensure there is sufficient room surrounding the drum, then fold the duvet in half before spreading it out in your machine. You may need to take your duvet to a laundromat with commercial-sized machines.
Let your duvet air dry if possible.
Duvets can vary vastly in pricing depending on material, design, and size. Pricing can start below $85 and exceed $1,000. Materials like humanely harvested goose down or wool tend to fetch a premium, as does silk. Meanwhile, down alternative and blended materials tend to be cheaper.
As with pricing, return policies and warranties on duvets can vary vastly depending on manufacturer. We’ve seen everything from 100-night sleep trials and lifetime warranties to no-return policies. Keep in mind that a reputable manufacturer should offer a multi-week return policy, at least a one year warranty, or both.
There are many benefits to both duvets and comforters. That said, the following are reasons why you may prefer a duvet insert for your home:
