18 Tog Extra Warm Duvets FAQs

What is the warmest tog duvet?

An 18 tog duvet is our highest tog rating, making it an extra warm duvet. It is ideal for cold homes and very chilly weather, no wonder some people call an 18 tog duvet an Arctic duvet!

What happens when it gets too warm in the summer?

Our 18 tog duvet is designed to be comfortable all year-round. When the weather warms up, the duvet separates into two lighter parts - a 4.5 tog and a 13.5 tog. The 4.5 tog layer is perfect for summer nights, while the 13.5 tog provides warmth during cooler months. When it turns really cold again, you can easily clip them back together for the full 18 tog cosiness.

How do I decide whether I need an 18 tog duvet for the winter?

The right tog duvet for winter depends on how warm you want to stay, how cold the weather is and how cold your bedroom gets in the winter. A Soak&Sleep 18 tog duvet consists of a 13.5 tog duvet and a 4.5 tog duvet joined together with a cufflink fastener.

Because our 18 tog duvet is made with a combination of two separate duvets, you can remove the lighter 4.5 tog duvet for a lighter – but still warm – 13.5 tog duvet if you find you are getting too hot at night.

You can then store the 4.5 tog duvet and use it during the summer if you find your 13.5 tog duvet too heavy during the warmer summer months. Find out more about storing your duvets in our duvet care guide.

What is an 18 tog duvet?

An 18 tog duvet is the our warmest duvet rating, designed for the coldest winter nights. Made by combining a 4.5 tog duvet with a 13.5 tog duvet, it can be used as an extra warm duvet in winter or separated into lighter duvets for use throughout the rest of the year.

Who is an 18 tog duvet best suited to?

An 18 tog duvet is ideal for those who feel the cold at night, sleep in cooler bedrooms or enjoy a particularly cosy sleeping environment. It’s a popular choice during winter and in homes where extra warmth and comfort are needed.

Can I use an 18 tog duvet all year round?

Yes. Because an 18 tog duvet combines a 4.5 tog and 13.5 tog duvet, it offers year-round versatility. Use the 4.5 tog duvet on warmer nights, the 13.5 tog duvet in spring and autumn, and fasten both together for exceptional warmth during winter.

What sizes do your 18 tog duvets come in?

Our 18 tog duvets are available in single, double, king and super king sizes, making it easy to find the right fit for your bed.

How do I look after my 18 tog duvet?

Always check the care label on your specific duvet before cleaning. Many of our duvets can be professionally cleaned, while some are suitable for home laundering. Regular airing and using a duvet protector can help keep your duvet clean, fresh and comfortable for longer.
