Thereโ€™s nothing better than sinking into bed after a long day and burrowing under a duvet so deliciously soft and comfortable, that you fall immediately into blissful, uninterrupted sleep. To that end, not all duvet inserts are created equal. Some are plush, some are cooling, and some are crafted in luxurious fabrics. One thingโ€™s for certain, thoughโ€”finding the right duvet insert can definitely help you drift off to dreamland.

First things first: Whatโ€™s the difference between a duvet insert and a comforter, anyway? The real answer is, not much. โ€œA duvet insert is typically thinner than a comforter and is placed into a duvet cover to create the top bedding piece,โ€ says sleep coach Kelly Murray of Kelly Murray Adult Sleep Consulting. The biggest thing to keep in mind is what you want your duvet insert to do for you. Do you want it to keep you cool, warm you up, be used year-round, or be changed out seasonally?

The best duvet inserts, at a glance:

What is the purpose of a duvet insert?

Above all, a duvet insert should keep you comfortable while you sleep. You may sleep hot or cold, you may like a heavy comforter or one with a lighter weight. The choice is really up to you. โ€œThe main function of a duvet insert is to provide extra warmth while allowing for customization in material and versatility in washing and drying options,โ€ Murray says.

What to look for in a duvet insert

โ€œDuvet inserts are great for sleepers who prefer customization,โ€ says Murray. This is becauseโ€”as the name suggestsโ€”you place them inside a duvet cover, so you can change them out with the seasons or your other design whims. Before shopping for a duvet insert, consider the following:


Duvet insert shells tend to be made of wool, cotton, synthetic fibers (like polyester), and silk. Like the outer cover, the fill can also vary. You may find duvet inserts with any of the following fills:

  • Wool. โ€œItโ€™s naturally moisture-wicking, fire-resistant, mold-resistant, and dust-mite resistant,โ€ Murray says.
  • Long-strand mulberry silk. In addition to being moisture-wicking and both mold- and mite-resistant, itโ€™s also hypoallergenic and breathable.
  • Cotton. This lighter-weight fill is also breathable and hypoallergenic.
  • Down feathers. โ€œThey expand, allowing air to circulate, which helps with thermoregulation,โ€ Murray says. โ€œItโ€™s also very cozy and comfy.โ€

The fill can often be down or down alternativeโ€”so if youโ€™re allergic to down or want a more ethical optionโ€”there are still options out there for you.

Your body temperature

โ€œChoose a natural fiber fill that errs on the cool side to ensure your body doesnโ€™t get too hot in the night, as overheating causes sleep disruptions,โ€ she recommends. This is because natural fibers (vs synthetic fibers) are more breathable and thermoregulating, perfect for hot and sweaty sleepers. โ€œNo matter how breathable the outside cover is, if the filling traps heat, the whole piece of bedding is going to keep you hot.โ€ She recommends looking for fills in wool, long-strand mulberry silk, or kapok fiber since these natural fibers tend to be the most thermoregulating and breathable.


Duvet inserts tend to be crafted one of two waysโ€”with box stitching, which helps keep the fill evenly distributed, or baffle box construction, which connects the outer layers and keeps the down from shifting. โ€œBaffle box construction is ideal for higher fill power duvets, as it maximizes warmth and maintains an even distribution of down,โ€ Murray says.

Whatโ€™s the difference between a comforter and a duvet insert?

It really boils down to whether you want to put one inside a duvet cover or not. Many duvet inserts can actually double as comforters if youโ€™d prefer to use them on their own. However, duvet inserts may also be thinner than comforters and stuffed with different fills. โ€œComforters only offer possible customization of the filling and outer shell material,โ€ says Murray. โ€œIt can be much harder to nail down the perfect combination for sleepers this way.โ€

Can you wash a duvet insert?

Yes. However, the material of your duvet insert will determine exactly how it can be washed. Some materials, like wool, can be washed but not put in the dryer, so itโ€™s important to read the care labels carefully. If youโ€™re placing a duvet insert inside a duvet cover, you can also go longer without washing, since it wonโ€™t be touching your skin directly while you sleep.

Does the fill power of a duvet insert matter?

If youโ€™re shopping for a duvet insert with real down fill, youโ€™ll notice that it has a fill powerโ€”which translates to how much it fills up until reaching its maximum loft. A higher fill power means more warmth with less weight. โ€œItโ€™s an important aspect to consider because it directly impacts the warmth and quality,โ€ Murray says. โ€œLook for a range of 500-700, as this typically results in a good balance of warmth and comfort.โ€

You may also find that higher fill powers translate to more expensive duvet insertsโ€”so if youโ€™re budget-conscious, thatโ€™s something to look out for.
