5 Important Factors to Consider When Choosing a Duvet

Ooh, it is hot, but it is also freezing. It is either too hefty or too light. Too fluffy, too flat…

Choosing the ideal duvet is a bit like the Goldilocks myth! However, finding the “perfect” duvet can make a huge difference in the quality of your sleep. So, it is worthwhile to spend some time determining which duvet is best for you.

There are numerous elements to consider to ensure that you can sleep soundly night after night.

So, here is a simple purchase guide for you to follow, and you may narrow down your options step by step to select a duvet that is perfect for you.


Natural (down, silk, bamboo, wool) or synthetic (down, silk, bamboo, wool) fillings are commonly used in duvets (microgel, microfiber, hollowfiber).

Down is the delicate feather layer found at the roots of a bird’s bigger, more stiff feathers. Down occurs in a variety of colors and qualities, based on factors such as the bird’s maturity and species. Duck or goose down are the most common fillings for duvets. Duck down is often cooler and lighter, whereas goose down is warmer and more insulating due to its bigger size.

Duvets packed with silk and bamboo are completely hypoallergenic, making them suitable for persons with sensitive skin and allergies. These natural fibres are great insulators and drain moisture away from sleepers, keeping them cool and dry. They are also a fantastic alternative for warmer sleepers because of this.

Wool fill may wick moisture up to a third of its weight! This contributes to a fresh, dry sleeping environment. Wool is also a sustainable textile because it is made from a renewable, animal-friendly resource. Wool is a little heavier and denser material that works well as a year-round or winter duvet.

Finally, synthetic fillers that mimic down, such as microgel, are available. Microgel is hypoallergenic and easy to care for because it is comprised entirely of polyester. A microgel duvet could be the perfect solution for individuals looking for a low-cost, high-value choice. But it is worth noting, to equal the warmth of a down duvet, a microgel duvet requires roughly three times the amount of filling. So synthetic duvets can be a bit heavier on the body.

Duvet size

This may sound like a no-brainer, but you might not want to match your duvet size to your mattress size, so it is something to think about.

Many individuals choose a duvet that is one size larger than their bed frame so that it drapes well over the mattress’s end, giving a lovely drape effect. It also eliminates the nighttime tug of war for the duvet cover!

Duvets are available in single, double, king, super king size duvet, and emperor sizes, so once you’ve decided on your filling and tog, you’ll have lots of options.

Fill power

Fill type is only one factor to consider. Another important element is fill power! The weight and warmth of your duvet are determined by the combination of fill type and fill power. So, what exactly is “fill power”? Simply put, the volume of filling in your duvet is what this term refers to.

Fill power, in the case of non-down duvets, equals the amount of filling utilized and defines the weight of the duvet. As a result, the heavier the fill, the warmer the4 duvet!

With down, things get a little trickier…

The volume or “loft” created by down is referred to as “fill power.” As a result, with a higher fill power and less filling, you can attain a higher fill power with less filling. It all comes down to how much space the down takes up, not how much down there is ounce for ounce.

Tog rating

The essential word to look for when it comes to warmth is ‘tog.’ Once you have decided on the filling, you’ll need to choose a tog rating for your duvet.

Consider the temperature of your room, how warm you are when you sleep, and how the temperature of your room varies from season to season.

Summer 2.5-4.5

Spring 6-9

Autumn 10.5-13.5

Winter 15-18

Keep in mind that all-season duvets are also available. These are made up of two separate duvets that are clipped together to make them warmer or lighter depending on the season.

All seasons 4.5+9=13.5

All seasons 4.5+10.5=15

Outer shell

The ticking is the duvet’s outer shell or casing. The thread count of a duvet is usually used to determine its ticking. Anything with a thread count of more than 220 is considered “down proof”. So, a cloth with a higher thread count is not necessarily more down proof!

The higher the thread count, however, the softer and lighter the exterior cloth. This permits the down filling to have more loft and a smoother hand-feel.

Alternative fibers, such as bamboo, can also be used for ticking. The temperature-regulating characteristics of a bamboo shell make it a perfect choice for warm sleepers.


The creation of duvets can be done in a variety of ways. However, one of the most effective approaches is known as the “baffle box”! In a nutshell, this entails stitching a grid of boxes into a duvet. These boxes allow the down to loft and stay properly distributed, ensuring that there are no cold areas.

The “stitched box” is another popular method. A grid is stitched directly through both layers of ticking with this method. Cold areas might form along the sew lines when down is scarce and compacted, which is a downside of this method. However, your duvet will have a more sculpted appearance, and if you are hot, having some cool patches may be beneficial.


Overall, selecting the ideal duvet is a matter of personal preference and requirements. Begin by determining what level of warmth you require, and then narrow down your options by considering factors such as filling, ticking, and construction.

Finally, a quality duvet is an investment that can last up to 20 years. That is a total of 20 years of better sleep (and a better quality of life).
