Duvet Fillings and Complete Tog Guide


How To Choose Most Suitable Tog For You

A Good Nights’ Sleep Starts Under The Right Duvet


You can make your bedroom the heaven of comfort choosing ideal bedding for you and ensuring that you drift off under the best possible covers. Experts recommend that the bedroom temperature is set to 16 - 18*C (60.8 – 64.4F), and your body temperature is regulated with a duvet instead, to help you sleep well, wake up rested and with a clear head. 

Our bodies are all very different and finding the perfect duvet “partner” is a very personal matter.

There is definitely no one tog fits all. To help you find the perfect duvet for your body, our resident Sleep Expert, Christabel has put together a simple guide below to help you decide starting by learning what tog actually is!

What Is A Tog?

Duvets come with their own scale of warmth, called the “tog” rating, however thicker doesn’t necessarily mean warmer. Natural filling duvets can feel lighter than their synthetic equals, but they are able to trap air better and therefore provide more warmth!

The tog is simply a measure of thermal insulance, meaning how well the material inside a defined area (duvet) is protecting you against outside thermal factors like heat or cold. The scale goes from 1 tog (the coolest) to 15 (the warmest – ideal for double-digit subzero temperatures). There are many duvets on the market to suit all sorts of tastes and changing climates, as well as budgets and health conditions. Generally, bedding industry experts recommend for summer you would want 1 - 7 tog rating, whereas between 9 - 10.5 tog rating or above should keep you warm in the winter, depending on your climate, however, this is merely guidance.

Choosing A Tog Rating For You

Being too hot or too cold at night is a recipe for bed sleep. If you live in a climate where seasons are well defined, it can take some forward planning to transition between them. If the climate you live in doesn’t change all the much seasonally, an all-year-round duvet is probably the best option for you.

Tog rating should never be considered in isolation, as you also need to think about how warm does your bedroom normally get? What climate do you live in? Will you be sharing a duvet with your partner or sleeping under it alone? What is your budget for bedding? How well does your body naturally regulate heat?

At Naturalmat, we handmake duvets from white goose down and our organic lambswool; the same lambswool we use in all our mattresses. To help you decide, below is a simple chart of the different togs you will find in our shop.


It is worth noting that out Organic Lambswool duvets come with cotton ties around the edges, so if you want an extra warm duvet (of up to 13 tog) you can tie our 300g and 500g duvet together, or to achieve the equivalent of 10 tog rating (for that all year-round cosiness) you could tie two of 300g duvets together.

Does Duvet Lose Their Tog Value

Having settled on the perfect duvet for you, you may wonder if that will decrease over time, and how long you have to enjoy your duvet before you need to replace it… well, like most things in life, duvet don’t last forever. Just like pillows and all other bedding, duvets will show signs of wear and tear over time. Choosing wisely to start with and opting for duvets made with natural fibres will ensure you get to enjoy your duvet for longer. According to the Sleep Council, you should consider changing your duvet every 5 years, however with proper care and regular cleaning you can keep your natural fibre duvets longer. All Naturalmat duvets are strictly dry clean only.

Natural Duvet Fillings

After you have worked out how warm you like your bed, it’s time to think about what to fill that duvet with. There are many reasons to go for natural duvet fillings. Natural fillings like white goose down, feathers and organic lambswool, which are used in our duvets, have no chemicals, so you can rest assured you are not sleeping under anything toxic. Due to the ability of the natural fibres to trap air better and provide more warmth less filling is needed. It’s simply an irresistibly luxurious feeling to be sleeping under a soft and fluffy feather and down duvet. Natural fillings are also very breathable, meaning your skin is breathing through the night and generally it feels lighter around your body, so don’t be fooled into thinking that heavier duvet means warmer – it doesn’t.

To make things even simpler, we offer only two types of duvets.

Goose Down Duvetsnaturalmat-goose-down-duvet

Our white goose down duvets are luxurious, soft and fluffy and made by cleverly combining 70% of white goose down with 30% of feathers. Feathers give the duvet loft and structure with the down adding plump cosiness and comfort.

Our goose down duvets are all completely chemical free, encased in 100% cotton cambric casing and come in two ratings, one for winter 9 tog and one for summer 4.5 tog.

Organic Lambswool Duvetsnaturalmat-lambswool-duvet

Perfect for those with allergies, our organic lambswool duvets offer a slick and slender profile and are somewhat different from the traditional and plush down duvets. However, these quilted duvets are simply amazing at regulating temperature, due to wool’s natural properties.

The organic wool filling in our 300g (approx. 3-5 tog) and 500g (approx. 6-8 tog) duvets is incased in 100% cotton cambric casing and is expertly made to order by hand in Devon.

Togs for all the family

Picking a duvet for yourself is hard enough, but picking it for your child can be a whole different level of complicated! Check out our tips by our Sleep Expert, Christabel about choosing a duvet for your child.

It is not recommended that children have a duvet under the age of one. Young children tend to be warmer than adults, so when they get a bit bigger you can start them off on a smaller tog duvet, like our Organic Lambswool duvet 300g (which is roughly tog 3-5), and as they grow you can add another 300g duvet by tying them two together.

After all, happily sleeping child is a happily sleeping parent too!
