Duvet Guide - the Handbook
Snuggly, warm, fluffy, cozy, lightweight, and long-lasting - these are just some things we all love about (or hope to get from) our duvet.
It can sometimes be a little daunting trying to understand the specification and terminology used. For example, the difference between down and synthetic fillings, tog ratings, and the correct size are just some of the questions you may have! Read on for some insightful information to help you make our decision.
Finding the right duvet
A great overview of what you should be looking for when trying to find the perfect duvet for you; scroll down for more detailed information.
Filling: This refers to the fill used for the duvet. This can be goose or duck down (light and fluffy), feather (warm and chunky), a synthetic fill such as micro- or hollow-fibre (affordable), or a natural fill such as silk or wool.
Casing: the cover (or 'shell') that your duvet is made of, and that keeps your filling in place. This is usually made of cotton, though budget duvets often feature synthetic covers such as microfibre. Pure cotton casings are usually soft and supple, and make for a breathable duvet.
Construction: should high-quality duvets usually feature 'baffle boxes' to keep the filling in place and prevent clumping and cold spots.
Size and Tog: sizing is of course important to make sure if fits on your bed properly! Tog refers to the warmth and level of insulation that the duvet provides.
All about your duvet
You now hopefully have a preliminary overview of what makes a duvet - read on for some more detailed information.
Fillings - the lowdown
The duvet filling plays the most important role in determining warmth and insulation; so (whilst tog is a great indicator) a down duvet will offer superior insulation than an equivalent tog microfibre duvet.
Feather and Down - which comes from duck or goose - is considered some of the finest insulation available. It's both warm and lightweight, offers great longevity and easy to maintain. There are a wide range of variations and origins of the filling, and a range of blends such as pure down, feather and down blends, or feather. Pure goose (or duck) down is the finest of the fillings, and offers superior warmth, lightweight and loft. Feather and down blends contain varying ratios of down and feather, which provide a heavier feel than pure down duvets.
Down (and feather) is sourced from various regions across the globes, with each region having their own distinct qualities and difference in specification. Canadian (Hutterite) goose down is sought ofter thanks to its relative scarcity and consistency; Hungarian down is widely available, and in a wide range of qualities - for our Edelweiss range we've sourced some of the finest goose down filling available. The combination of light-weight, breathability and superior insulation makes goose down some of the most sought after fill - the perfect choice for a winters night, as well as for warmer seasons.
There are a range of ways in how the quality of down is measured, with the most widely used metric being 'fill-power'. Fill power, a volumetric specification measured in cubic inches is a calculation of the amount of space an ounce of down occupies when allowed to reach its maximum loft; larger clusters of down have higher fill-power. For example, one ounce of 800 fill-power down will occupy 800 cubic inches when compressed. This means that the filling is fluffier and loftier, offers better insulation (and thus allows for a lighter duvet as less filling is required to achieve the same or better warmth and insulation than lower quality down). Fill power ranges from 500 to circa 800 - the higher the better.
Sourcing is an important factor when considering a down duvet, and we're pleased that our feather and down is ethically sourced - you can read more on our welfare policy here ➞
Synthetic and natural fillings are becoming increasingly popular thanks to their affordability and improvements in quality. We have a range of 'down-alternative' duvets, which feature fibre fills for an affordable and comfortable duvet. Silk, a complete natural fibre, is another down-alternative fill for a luxury natural option.
Casing - your duvets cover
The casing (sometimes referred to as the 'shell' or 'cover') is another important component of the duvet. Superior duvets feature pure cotton casing, and high thread-count casing ensures a supple and soft fabric (which doesn't make any 'rustling' noises). As an alternative to pure cotton, some budget duvets may feature casings made of synthetic materials.
Our down duvets boast double stitched edges and baffle box construction. Baffle box is a technique of stitching internal squares in the duvet to ensure filling remains evenly distributed in its place to prevent clumping and cold spots in the duvet.
*Please note, the norm for 4.5 tog duvets are to be stitched through (as opposed to internal walls) due to the lower amount of filling used in the duvet.
Warmth and sizing
In simple terms, tog indicates the warmth the duvet will provide; the higher the tog (and thus usually weight of duvet), the greater the level of insulation provided by the duvet. Choosing a duvet of course depends on your needs and the weather. Following is an indicator of warmth recommended for the seasons.
Summer - 4.5 tog // Spring & Autumn - 10.5 tog // Winter - 13.5 tog // All-seasons (9 + 4.5 tog ) - duvets that fasten together (using button along sides and edges) to form one duvet (13.5 tog equivalent), or can be separated and used individually.
Our duvets are available is various sizes to fit your bed, as follows (in cm):
Single - 135 x 200 // Double - 200 x 200 // King - 230 x 220 // Superking - 260 x 220
Caring for your duvet
It's important to take care of your duvet to keep it in tip-top shape for (many) years. Taking good care is rather easy and will maintain the state of your duvets and increase its longevity.
Down (and Feather) Filling
- Fluff up your duvet by giving it a good shake every morning. It's also a good idea to leave it out and allow to air out when changing your bedding.
- Professional laundering is recommended - most competent launderettes offer a 'feather/down duvet' cleaning service.
- These duvets can be machine washed; ensure your washer and dryer has ample space. Use gentle detergent (no softeners, or harsh cleaning agents), and run on a 30/40°C delicate cycle. Should be thoroughly dried on low heat (use drying balls to aid drying process, and remove occasionally to fluff up). Remove promptly when dry.
