This is the fluffy sub-layer on the underside of the bird. It feels supremely light and lofty; the higher the down percentage, the softer and airier the duvet will feel.

One of the most popular fillings for duvets. Feathers and down from different locations and species can have different properties.

Goose is perceived as more premium than duck, as the clusters of down are larger and puff back up very quickly after being used.

The Icelandic eider duck grows extra-large and supremely fluffy down clusters, which farmers hand-pick from each nest once they have migrated, without disturbing the natural environment.

Micro-clusters of synthetic fibres are blown into the casing until perfectly even to mimic the down-like feel of a natural duvet.

Tiny micro fibres glazed with a silicone layer which allows them to slide over each other smoothly, resulting in a down-like feel.

Feels light and cooling to sleep beneath during warm summer nights.

Keeps you snug during milder spring temperatures, without overheating.

Warm when it’s cool and cool when it’s warm – ideal for all year round.

High warmth rate designed to feel cocooning and warm during cold winter nights.

Some of our duvets are designed to be joined together using cuff links or buttons, so you can customise your own tog rating.

A down-alternative or hypoallergenic filling is ideal, and easy to wash regularly. Some of our natural ranges are Nomite™ certified, meaning fillings are sealed in a tightly woven fabric cover which acts as a barrier against dust mites.

Sleeping with the window open, or in older homes, can necessitate a higher tog than you would usually choose, while you may want to go for a lower one if you tend to run hot.

Generally, choose the same size duvet as your mattress, however you could also try going a size up if you have a taller bed or are sharing the covers.
