If you're a hot sleeper or suffer from night sweats then you might also find this high down-mix fill too warm; opt for a more breathable wool-filled duvet like Floks Luxury British All Seasons Wool Duvetinstead to avoid overheating. That said, personally, we think 13.5 tog remains one of the best winter duvet weights, with some finding 15 tog can retain heat a little too much during the night and lead to overheating. Spend some time looking for a new duvet and you'll soon realise there are a whole host of duvet fillings available. From hollow fibre to goose down, synthetic to natural, the array of terms and materials can fast become a little overwhelming. Long thought of as the Holy Grail of duvet fillings, down creates a plump, squishy and super soft duvet.However, that luxury feel comes with a luxury price tag to match. To help you get to grips with the basics, we've broken down the pros and cons of most common duvet fillings below.

Buy it if: you want an affordable winter duvet that still feels both warm and luxurious. This recycled polyester fill duvet has 10% silk mixed in, and whilst the proportion doesn't sound huge, it really makes a difference to the way this duvet feels, with a more luxurious touch and really nice drape on the bed, whilst still being lightweight. Even better it's a relatively budget buy, and made from certified recycled polyester from waste (like plastic bottles or manufacturing off-cuts) which helps the movement towards a more circular economy by reducing waste going to landfill. Compared with virgin polyester, recycled polyester helps conserve crude oil reserves during fibre production. Don't buy it if: you really want to layer on the warmth. This 13.5 tog duvet is plenty snuggly enough, but we think the wool and down options just pip it to the post in terms of cosiness. That said, this synthetic option is far easier to care for as it's machine washable and can be tumble dried on a low heat setting. Don't buy it if: you truly want to splash out on the best duvet for your boudoir. This option is very good for its price, but the higher feather mix does mean it feels more 'clumpy' than the 90% down alternatives on our list. That said, this is still a great buy, and the addition of feathers does make the duvet a little more breathable than a duvet with a higher down percentage, albeit not quite as warm.If you’re struggling to work out what the best tog duvet is to see you through summer heatwaves and plummeting winter temperatures then an all-season duvet could be the answer.
