Buying Guide for the Best Duvet Inserts
If you’re shopping for a new duvet, you may be wondering what makes it different from a comforter. It’s a good question! Both add fluffy warmth to your bed, and both differ from blankets thanks to their construction, which includes some type of internal fill. However, duvet inserts are generally designed for use inside a duvet cover (though that’s not always the case).
Just as your pillow benefits from a case to keep it clean, so does your duvet. Plus, using a cover means you can customize the look of your bed, adding color and pattern. That’s a benefit, since many duvet inserts are typically available in white.
As you shop for a duvet, it’s important to consider your personal sleep needs and preferences. That will help you zero in on the materials that will serve you best.
Types of Duvet Inserts
Like comforters, duvet inserts come in standard sizes to accommodate beds of all sizes. And just like comforters, duvet inserts are also made with different fill materials. Choice of fill will dictate how a duvet feels and looks. Common fill materials for duvet inserts include:
- Goose down. If you love the idea of a lofty, airy, cozy duvet, goose down tends to be the best material. It’s important to look for certifications from the Responsible Down Standard (RDS), the International Down Standard, or Downmark, all of which indicate high quality and compliance with strict animal welfare principles. That way, you can be certain that the down in your duvet was harvested ethically and humanely.
- Down alternative, like microfiber and polyester. These materials are often more cost-effective than real down and are a good option if you have allergies.
Benefits of Duvet Inserts
Duvet inserts and comforters have many similarities. But one big advantage of the duvet insert is the fact that it’s often paired with a cover. Not only does that give you lots of flexibility in terms of aesthetics, it also offers an extra layer of protection to your duvet insert.
Duvet inserts also tend to be a little fluffier and warmer than comfort, because they’re generally made with high-quality materials. And while you will likely spend more money on a true duvet insert, you can expect a longer lifespan with proper care.
Considerations for Duvet Inserts
As you shop for a new duvet insert, remember to factor for your personal needs and preferences. Here’s what else to keep in mind.
- Construction. A well-made duvet insert is key, and construction styles like baffle box help ensure even distribution of the fill. That way, you can avoid a scenario in which all of the cozy warmth is bunched on one side. Look for corner loops as well—they help keep your duvet insert secured inside the cover.
- Price point. Duvet inserts can range in pricing, veering to the higher end for better materials and certifications. You don’t necessarily need to pay a premium for a great duvet insert, but keep in mind that you generally get what you pay for.
- Ease of care. If you use a duvet cover, you won’t need to wash your duvet insert itself very often. Still, it’s wise to double check the care instructions before you purchase just so you’re clear on whether or not machine washing is an option.
- Comfort. Depending on where you live, the time of year, and whether or not you usually sleep hot, you may want a lighter or heavier duvet. Pay attention to the weight of a particular duvet insert as you shop—that will tell you how warm it will feel.
FAQs about Duvet Inserts
What is a duvet insert?
As the name suggests, a duvet insert is inserted into a duvet cover. Together, these bedding basics add warmth and coziness to your bed.
What’s the difference between a duvet insert and a comforter?
Duvet inserts and comforters are often referred to interchangeably, as is the case in many of the options we listed above. But while both are a top layer designed for warmth, a comforter can be used by itself, while a duvet insert typically requires a cover.
What’s the best duvet insert filler?
This comes down to personal preferences and sleep needs. If you sleep warm, temperature-regulating materials are a better choice than down, which offers high insulating properties. If you like a cozy, lofty feel, down is a good option. In both cases, it’s best to opt for high-quality materials from a trusted brand to enjoy long-term performance from your duvet insert.
What kind of duvet insert do hotels use?
Many hotels use goose down duvet inserts. That’s what makes hotel bedding feel so fluffy, with a cloud-like softness. If you want the airy feel without actual down, down-alternative duvet inserts are designed to mimic the plushness.
