Expert guide to duvets

With more than 20 varieties of natural filling duvets and synthetic fibre duvets on offer ranging from light 3 tog to extra warm 15 tog duvets, our expertise and extensive selection are a winning combination for the perfect night's sleep.

With a comprehensive collection of branded bedding from our very own Dunelm duvets to Fogarty, Slumberland and luxurious Dorma available online and in store we'll help you identify the size and filling that will help you drift off to sleep and stay perfectly cosy all night long.

Tog ratings

Duvets come with their own scale of warmth called a 'tog' rating, and thicker doesn't necessarily mean warmer. The tog rating refers to effectiveness of a material's thermal insulation, using an ascending scale ranging from cool and lightweight low tog duvets at 1.5 and 3 tog, up to the extra cosy 15 tog duvet.

Tog rating denotes the duvet filling's ability to trap air and therefore provide more warmth, which is something natural filled duvets are able to do with less materials than synthetic fibre duvets. This means natural filling duvets can feel lighter than their synthetic equals.

Duvet fillings come in different weights and warmths, from ultra lightweight 1 tog duvets moving up in cosiness to 15 tog duvets that will keep you super snug in winter. For convenience, we also offer all season duvets that combine a low and medium tog that can be used together as a thick high tog duvet on particularly cold nights, and separately for warmer evenings.

Duvet fillings: natural or synthetic?

For most people, the choice between natural or synthetic fibre duvets is merely a matter of taste and budget. However, if you or a member of your family suffer from allergies it's wise to steer clear of natural filings that can exacerbate problems. Synthetic duvets are available for 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 are able to give a higher level of warmth because feathers are naturally adept at trapping air for insulation. Feather or down duvets do this with less thickness than their synthetic counterparts, though synthetic duvets with the same tog rating tend to have a lighter feel.

Duvet sizes

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 their bed equivalent. Buy your bedding in the same size as your bed and your duvet 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).

Along with a full range of duvet sizes, we also stock a choice of bed linen to fit our bedding, including super king size duvets.

Children's duvets

Children should not sleep under anything warmer than a 10.5 tog duvet. An adult size duvet will trap more air around the smaller frame of your child, therefore they will be kept warmer at lower tog ratings and should not require anything heavier.

For babies we sell specialist cot quilts and blankets to tuck them in safely.

Duvets are not suitable for babies under 12 months.

Caring for your duvet

We recommend you use duvet protectors and pillow protectors on all of your bedding for an economical way to preserve the quality of your bedding.

Our bedding protectors are made from non-allergenic hollowfibre, making them suitable for the whole family. They help to reduce the need for washing and defend against dust mites.

We also offer a wide range of waterproof bedding protection for a hygienic way to defend against accidents.

  • Always follow the care instructions found on a label sewn into a seam or on the original packaging.
  • Dry and air your bedding thoroughly before returning it to your bed.
  • Please note, natural fibre bedding cannot be dry cleaned as chemicals will damage the fillings.
