Getting those fingers and toes at just the right temperature is a key component of promoting good sleep. Experts recommend an ambient room temperature of 16-18°C to help you sleep well. But what part does your duvet play in keeping you cosy or cool?

Ever wondered what those numbers on your duvet’s care tag mean? Today we’re talking togs, thermal insulation and seasonal duvet swaps…


Duvet togs – how low can you go?


The ‘tog’ is a measurement of thermal insulation based on how good your duvet should be at trapping air to keep you warm. Because some fillings are naturally better at trapping air, you don’t necessarily need a heavier duvet to be more insulated.

So, where does the tog scale of warmth start and end? Quilt togs start at a light and airy 4.5 and go up to a super snuggly 13.5. There are lots of options in between to help you find the perfect tog rating for you.


A duvet for all seasons


Being too hot or too cold is a recipe for a rough night's sleep. When transitioning between the seasons, this can take some forward planning.

  • During warm weather, reach for duvets with a 4.5 tog. For spring and autumn, something in the middle around 10.5 should do the trick.
  • When the cold weather closes in, a tog of 13.5 or above will see you’re kept cosy as can be.
  • If you don’t have the space to store duvets out of season, try and stick with a midway tog (around 10.5). Then add extra bedclothes when the weather demands, or strip off a layer if you need to.

Children’s duvets


Duvets and pillows aren’t suitable for babies and infants under the age of one. They should sleep with blankets, tucked in for safety, or specially designed infant sleeping bags.

Even after their first birthday, you’ll need to stick to a lower tog rating until children reach around the age of ten. This is because air is more easily trapped around their smaller frames, causing them to warm up and potentially become uncomfortable.

Always be mindful of this wherever you travel as you may need to take lighter bed linen or blankets with you.


Other duvet comfort factors

Don’t forget, it’s not all about togs when it comes to duvet comfort. How your duvet is filled will also be a factor in whether it suits you and your sleep style. Natural fillings such as down tend to be lighter weight because you don’t need as much filling to trap the air. So, if you like to be able to fling your duvet off easily, something like this may be for you.

While some can prove to be heavier, synthetic duvet fillings are likely to be a better choice if you suffer from allergies and are generally lower priced too.

If you find you feel the winter chill, you could consider an electric blanket to avoid swapping your duvet each season. With three heat settings, a heated blanket is great for pre-warming your bed or warming up once your central heating has been turned off for the night.

What’s your duvet tog rating of choice? Do you have one duvet that sees you through the seasons or do you swap yours round when the cold spell starts?
