Duvet Insert Ultimate Buyer’s Guide

Duvet Insert Ultimate Buyers GuideIn this section, our Team of Experts have put together the most comprehensive guide to help you find the best duvet insert for your bed.

Before you go out and spend your money on a duvet insert, there are several important points you Must Keep in Mind!

To start, you should know what you need to buy! Do you need a Duvet Insert or should you get a Duvet Cover?

Since this is the most common question people have when shopping online for a duvet, we will start by explaining what each one is.

What is a Duvet Insert?:

A “Duvet Insert” is the main part of the comforter and contains the stuffing (Down Filling). You should buy the best-quality duvet insert for your needs and think of it as an investment.

There are several different types of duvet (Comforters). I’ll explain below what you should look for to help you decide which duvet insert will be best for you.

What is a Duvet Cover?:

A “Duvet Cover” is exactly what it sounds like, a beautiful cover for your precious duvet. Owning several duvet covers allows you to change the style of your duvets by switching covers according to your mood.

The main reason for buying a duvet cover, also known as a comforter cover, is that it protects your comforter.

Down bedding is an investment! The highest-quality comforter or duvet can last for more than a decade. However, down bedding is very heavy and doesn’t wash easily.

A duvet cover will protect your bedding from spills, stains and normal wear and tear. Also if you want a different look of your bedding, changing your duvet cover is cheaper than buying a new Duvet Insert.

Different Types of Duvet Fillings

The best duvet inserts are filled with down. But not everyone wants to invest in a down comforter and some might be allergic to “Down”.

The types of filling you’ll find in duvet inserts are:

  • Natural Filling (Down Filling)
  • Synthetic (Down Alternative) Filling
  • Blended Filling

Natural Filling (Down Filling): Down-filled duvets are made from the soft under-feathers of geese or ducks. The filling is actual Down (under-feathers) from Ducks, Geese or a blend of both.  Down feathers provide the best insulation and padding while being softer than synthetic-filled duvets or comforters.

The down feathers in bedding help trap small air pockets. This provides a thermal barrier for great insulation and warmth without added weight. For the highest quality and best insulation, look for a comforter (Duvet) made with a natural All-Down Filling (Pure Down).

Hypoallergenic Down Filling: If you want the comfort of “Down Duvets” but are allergic to down, you should consider a Hypoallergenic Down filling:

  • Some hypoallergenic down bedding, features down that has been specially cleaned to eliminate allergy causing agents.
  • Other hypoallergenic down bedding contains down-alternative fills, which can range from normal synthetic fills to natural filaments taken from milkweed plants.

If these options still don’t fit your needs, you should consider buying a Synthetic-filled duvet instead.

Synthetic (Down Alternative) Filling: As the name suggests, it is the alternative to the natural down. It is man made with synthetic or polyester fibers. These are widely preferred because these are hypoallergenic which means while some people might be allergic to the natural down from duck or geese, these duvets don’t have those allergens to irritate your hypersensitivity.

There are some more variants to these which come in cotton or wool-filled duvets. These alternatives are cheaper than pure down but are bit on heavier side. Also, insulation of pure down duvet inserts is much more than that of down alternatives duvet inserts.

Fill power of Duvet Inserts

The Fill power tells you how much Down coves the “cubic-inch” area in the duvet insert. Down quality, expressed in terms of fill power, which is the volume of one ounce of down, varies between different down comforters.

Down comforters containing high fill-power down aren’t necessarily warmer than other duvets, but they are often lighter and fluffier because high fill-power down expands more than low fill-power down.

Fill Weight of Duvet Inserts

The “Quantity and Density” of down that’s inside the duvet insert is considered the “Fill Weight”. The measurement of the fill weight is always in ounces.

Duvet inserts with higher fill power will have less fill weight. It will be considered warm and light. Higher fill-weight doesn’t refer to the actual weight of down in the duvet,it’s just the opposite.

Box Stitch vs Channel Construction

Box-Construction- It’s basically the sewing of the fabric in large grid patterns that keep the filling in place and prevent it from bunching up in the corners.

(Box Stitch) duvets have seams that run in straight lines that form a criss-cross pattern. This makes your duvet insert look like a checkerboard of down-filled pockets.

Channel Construction- Duvets with channel construction have seams that run in straight lines to each other from the top of the duvet to the bottom.

These channels allow the “Down Filling” to move to different parts of the duvet. If your feet get extra cold or if you prefer different amounts of fill, channel construction lets you shift more down to the bottom of the comforter or to one side or the other.

Box construction is the most common construction because it keeps the fill firmly in place. However, some people like the versatility offered by channel construction.

“Gusset” Duvet Insert

Gusset is a more advanced way constructing your duvet insert. The walls inside the duvet are made of fabric making it thicker and fluffier.

Gusset duvets take more time and material to construct, making them more expensive than the previous duvet types.

Thread Count

We all know that fabric is made of threads. So it becomes a misconception that the more is thread count the better is material. But, that is not true. The quality of thread and the kind of weave used are more reliable factors to assess its quality. The weave are also of different kinds like plain, twill, oxford etc. but we don’t need to get into that discussion.

Based on the type of filling inside the duvet, the duvets can be classified as down duvet inserts and down alternative duvets. Let’s see what they are in detail.

Consider everything and then you can easily pick from our top choices given below.

Shopping for a single duvet may not seem like a complex matter as when you’re shopping for a new car or even the clothes that you wear. With cars and clothes, you probably take time to make sure that they feel right for you and what you need to do in case they don’t.

Shopping for the best duvet insert or any other kind of bedding should never be an exception to common sense. Don’t treat it as just as item you’ll plop on the top of your bed and not caring whether it will suit you or not. When shopping for a single duvet, you should at the very least tell yourself, “I want the best duvet that will be comfortable for me and at the best price I can possibly get.”

Duvet Insert Buying Tips

Tips to Finding the Best Duvet Insert

The main feature of duvet inserts is the flexibility of style. You only need to buy the very best duvet insert and use “Duvet Covers” to easily change its look. With a duvet cover, you won’t even need a bed sheet on top of it.

Duvet inserts (Comforters) should “Only be professionally dry-cleaned”. Using a cover for your duvet, allows you to simply wash the cover at home avoid taking the complete duvet to a dry cleaner.

Keep in mind that not all duvet inserts (Comforters) serve the same purpose. Some are meant for colder weather while other duvets are best for warmer nights.

There are many different terms when it comes to buying duvets. You should take a few minutes and get familiar with these terms to help you find the right duvet for your needs.

The first thing you should do is do some comparison shopping online. This doesn’t mean that you are bound to buy the single duvet online. Many prefer to buy it from a bedding department in a store. However, this shouldn’t deter you from still shopping online, comparing items from one store to the other and looking for the best price. A good place to start looking is Here, you’ll be offered a wealth of resources where you can compare the inventory and price between one place and another.

Furthermore, many sites you’ll be referred to include customer reviews which can help you decide if it’s worth investing your money at a particular site that may not be rated well. The reviews are not only about the items themselves but also about their experiences with the vendor. This leads to the next matter to keep in mind when shopping.

The reputation of the vendor is very important. First and foremost, you want to make sure that you are getting what you want to get and not be misled. If, for example, you come across an item at a store that tells you “Complete duvet set at 50% off”, you should always make sure that you’re going to get the duvet included in the set. It may only include a duvet cover and some bedding such as shams and linens, but no duvet.

If you are shopping at the store, check inside the package if you need to or have a salesperson open it for you to check if what you need is in there. If purchasing online, check with their customer service department if the single duvet you want is what you’re expecting if it’s not noted on the website itself.

Finally, check and make sure the store (online or in-person) has a return policy where you can return the item for cash or store credit if the single duvet is not up to your standards.Duvet Insert FAQ

Frequently Asked Questions

We get asked many questions regarding all types of bedding. However, in this section we will only focus on the most common questions related to comforters and duvet inserts. Feel free to leave a comment below with any questions you may have as well, we’d love to hear from you!

What is the Difference Between a Comforter and Duvet Insert?

Comforters and duvets are actually the same, except for a couple of differences.

Difference #1: Comforters come inside a stylish cover while most duvets are uncovered and just plain-white. In this case, you will need a seperate duvet-cover to protect it or change it’s look.

Difference #2: Comforters come in “multi-piece sets”, which include pillowcases and fitted-sheets, while duvet-inserts are sold separately.

What’s the Best Fill Power for a Duvet Insert?

An average duvet uses 600 to 700 fill-power down, with luxury duvets featuring fill powers up to 900 and low-end duvets using fills that are below 600.

If you’re looking for the best duvet insert for summer, a “Fill Power” below 400 will be perfect. Duvets with a fill power above 400 are best for cooler climates.

For maximum warmth, you’ll want to buy a duvet insert with a “Fill Power” that ranges from 600 and above.

While high fill-power means high price, 800 fill-power down isn’t necessarily better than 550 fill-power down. If you like duvets that feel dense, then you’ll probably enjoy a duvet filled with low fill-power down.
