Duvet Tog Guide

Even the comfiest mattress wouldn’t be complete without a cosy duvet to snuggle up under at night. But not all duvets are made equal, and the best weight and thickness for you will depend on the season, your home, and your personal preferences.

In this duvet tog guide, we’ll explain the tog system, how tog ratings work, and how it has an impact on your warmth and comfort, so you can work out which duvet is right for you. We’ll cover:

What does 'tog' mean?

You’ve probably already noticed that duvets are sold with a tog rating on the label and that quilts with a higher rating tend to be thicker. But what does ‘tog’ mean, exactly?

How tog works is it's essentially a measure of how effectively a duvet insulates heat. The higher the tog rating, the warmer the duvet will be, with 1 tog being very cool and lightweight, and 15 being the warmest. Typically, the thinnest, lightest duvet you’ll find on the market is 4.5 tog, while the thickest and heaviest is usually around 13.5 tog.

The right tog rating for you will depend on your personal preferences and certain environmental factors, including the temperature of your bedroom and the season.

What duvet tog is right for me?

Which duvet is right for you will depend on two key factors: the temperature in your bedroom, and your own preferences. As the temperature of your home will usually change according the season, it’s best to invest in two different duvets: one for summer, and one for winter. This will keep you cool on warm nights and snug and toasty when the mercury drops. In this duvet tog guide, we’ve shared what to look for in both types.

Best duvet tog for summer and spring

There’s nothing worse than being unable to sleep on a hot summer’s night, which is why you need to have a lightweight duvet that will keep you as cool as possible. A 4.5 tog summer duvet is perfect for the warmer months, and will keep you comfortably insulated without overheating. Some people also prefer the feel of a heavier duvet, even in warmer weather: if so, a 7.5 tog style might be a better option for you. Duvets made from synthetic fibres are usually better during this time of year, as they tend to be more breathable.

Best duvet tog for winter and autumn

During winter, you’ll need to swap your lightweight summer duvet for one with a higher tog rating that provides extra insulation on those chilly nights. A 13.5 tog winter duvet is perfect for the colder months, depending on how low the temperature drops in your bedroom overnight. Ideally you should try to keep your bedroom heated to between 18 and 21 degrees overnight but, if your home gets colder, then you could even go all the way up to 15 tog.

Your personal preference

Another key consideration is your own preferences. Every sleeper is different, and we all regulate heat slightly differently. Some people may like the snug, comforting feeling of a thicker duvet, while others could find these to be too heavy and cumbersome. If you’re ever in doubt, you can always opt for a duvet with a medium-warm tog rating — around 10.5 tog — and add a quilt or throw for those nights when you want a little extra warmth.

Adding a quilt is also a very handy solution if you share a bed with a partner who has slightly different duvet preferences from you, as you can adjust the weight and thickness on your side of the bed without disturbing them.

Your mattress

How warm you feel in bed may be affected by the type of mattress you sleep on. Many people find that memory foam mattresses retain more heat than traditional pocket sprung styles. So, if you have a memory foam mattress and you find it quite warm to sleep on, you may prefer to use a light summer duvet all year round, possibly switching to a slightly thicker 13.5 tog duvet in the winter months. This will help to stop you from getting too hot in bed.

Do babies need a duvet?

Babies under 12 months old shouldn’t have any kind of duvet at all, as this puts them at risk of suffocation. Infants of this age can also overheat very easily, so it’s much safer and more comfortable for them to have lightweight baby blankets and sleeping bags, instead. You can always tell if your little one is comfortable by feeling their tummy with the back of your hand to see if they’re very hot, and then adjust their blankets as needed.
