Some of us like a duvet that gently drapes over the body and others like a heavier duvet that creates more a cocoon-like, enveloping feeling. Both effects can be achieved with natural and synthetic duvets but allergies and natural body temperature need to be considered when buying the perfect duvet.
Natural or synthetic?
If you are prone to allergies, synthetic fillings should be your preferred option and natural feather fillings avoided. Man-made fillings such as hollowfibre and microfibre are non-allergenic by design and tend to be lighter in weight. They also offer a practicial alternative to natural fillings, as they can be laundered quickly and easily.
Feather and down filled duvets tend to be heavier than synthetic-filled duvets, particularly those with a higher feather content. Natural duvets have great thermal properties and are naturally breathable, so are often preferred by those who feel the cold and like to create a tucked up feeling at night. If you suffer from allergies or have a naturally warm body temperature, lighter synthetic duvets would be a better option.
High or low tog?
Tog is often mistaken for weight. A high tog does not necessarily mean that the duvet is heavy, it simply means it will be more thermally efficient and keep your body at a warmer temperature.
Lower togs such as 3.0 and 4.5 are ideal for summer or those who have naturally warmer body temperatures; an extra warm tog such as 13.5 is intended for winter use or those who tend to feel the cold more than most.
The table below is a useful reference when deciding on the tog that is best for you but also consider how warm your bedroom is and if you share a bed, as these factors will also impact on how warm you feel.
