Duvets Buying Guide
A good night’s sleep makes a huge difference to your day and the right type of duvet ensures you stay warm and comfortable in bed. We stock over 50 varieties of duvet, with both natural and synthetic fillings, in togs 1 to 15. As well as our own styles, you can also choose renowned bedding names such as Dorma, Hotel and Fogarty.

This buying guide will help you find the right duvet for you and your family. It’s important to remember that duvets aren’t suitable for babies under one year of age, so we sell a range of specialist cot beds to tuck them in safely..

What tog do I need?
Duvets come with their own scale of warmth called a 'tog' rating. This rating is about warmth, not thickness, so even if you find the fluffiest duvet ever, the tog is the part that makes the difference. The scale is simple, ranging from 1 to 4.5 tog for cooler options, to the extra-warming 15 tog. 

The tog rating tells you how good your duvet is at trapping air (which is basically what insulation is) and therefore provide more warmth. Natural filled duvets are often able to do with less materials than synthetic fibre duvets, which can mean they’re on the lighter side. We stock duvet togs of 1-15. Check out the table below to work out the best tog weight for you.

💡 DID YOU KNOW?
The term "tog" stands for "Thermal Overall Grade" and measures how well a duvet traps in heat. For example, a high tog duvet provides great heat retention while a low tog duvet is cooler and ideal for warmer weather. 

What tog is suitable for toddlers?
Toddlers need a lightweight 3–4.5 tog to avoid overheating, while children over 3 can use a 4.5–9 tog depending on the season. For winter, a 7.5 tog offers cozy warmth, and in summer, a 2.5–4 tog keeps things cool.

What size duvet do I need?
The size of your bed will usually dictate the size of your duvet, with single through to super king size duvets made to fit the standard dimensions of beds with the same name. Buy your bedding in the same size as your bed and your duvets will cover you comfortably, but if you like extra coverage try buying the next size up (e.g. a single bed with a double duvet).

Should I choose a natural or synthetic duvet filling?
For most people, the choice between natural or synthetic fibre duvets is matter of taste and budget, however, if allergies are an issue you’re probably better off with a synthetic filling duvet. They are available in all tog ratings and are non-allergenic by their nature, so are suitable for use by the whole family.

Generally thought of as a more luxurious way to sleep, the natural filings of down or feather duvets tend to feel warmer than synthetic duvets of the same thickness. Feather or down duvets can also feel heavier than their synthetic equivalents, so if you want a lighter feel synthetic could be the way to go.

How do cover fabrics differ?
While your duvet is likely to be encased in a separate duvet cover, choosing the right cover fabric is still important, when it comes to properties such as breathability, temperature regulation, washability and softness.

Should I own multiple duvets?
Whether you opt for an all-season duvet and stick with it all year or switch between a lighter and heavier duvet between summer and winter depends on your own preferences and requirements. Some people have ailments that mean they only ever need a lighter duvet but, for the average sleeper, it’s a good idea to have lighter duvets in summer and heavier ones in winter. An all-season duvet is a good option as it comes with a 10.5 tog and 4.5 tog duvet that clip together in winter and can be separated in summer.
