Although it will mean spending a little more, and may depend on your bed frame height and style, we'd generally advise sizing up with your duvet, especially if you sleep with a partner. Obviously, it isn't always convenient to have a different duvet for each season, so the middle ground of the 10.5 tog duvet is one of the most popular options.

Buy it if: you're looking for luxury as well as warmth. No duvet fill feels quite as sumptuous as down, and this Soak & Sleep Hungarian goose-down option is one of the best quality we've come across. It's super warm yet lightweight, drapes beautifully on the bed, and feels super luxurious – you'll instantly feel like your bedding has levelled up. The all-seasons option also offers brilliant versatility; use the 4.5 and 9.0 duvets separately in warmer seasons and combine to create 13.5 togs of winter warmth. Whether you want a warmer winter duvet to keep you snug as temperatures plummet, you're fed up with overheating during the night and are looking for a more breathable duvet, or your budget buy is past its best and you're looking to invest in a duvet that will add some real luxury to bedtime, we've rounded up the best duvets to shop in this guide. Best winter duvets Although you can get duvets in almost any tog rating, the most common togs are 4.5 tog which makes a great summer duvet weight, 10.5 tog which tends to be the best bet for autumn and spring, and 13.5 tog which offers good winter warmth. ALL SEASONS - Our duvets are made with a soft hollowfibre filling coupled with a soft touch cover giving you that cosy comfy feeling so you can enjoy great night’s sleep all night long.Don't buy it if: you're on a tight budget as this luxury duvet has a luxury price tag. If you're a hot sleeper or suffer from night sweats then you might find down too warm; opt for a more breathable wool-filled duvet instead to avoid overheating. And, if you're vegan, then the feather and down fill won't be for you. 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. Don't buy it if: the price makes your eyes water. As well as being the softest duvet fill, down is also the most expensive fill, and 90% Hungarian goose-down is pretty much the best quality you can get. If you're a hot sleeper or suffer from night sweats then you might find down too warm; opt for a more breathable wool-filled duvet instead to avoid overheating. And, if you're vegan, then the feather and down fill won't be for you. Don't buy it if: your priority right now is affordability or ease of care. Although we think it's well worth investing in the great night's sleep it offers, there's no denying the price is prohibitive, and this duvet is dry clean only.

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. A BETTER TOMORROW: Our products help save the equivalent of 750 Million plastic bottles from landfill each year To help you get to grips with the basics, we've broken down the pros and cons of most common duvet fillings below.An all-season duvet is made up of two separate duvets of differing togs – one lightweight and one midweight – that can be attached together into one single heavyweight duvet or used separately. The idea being that you can mix and match to ensure you have the perfect weight duvet for spring, summer, autumn, and winter. 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. The highest tog duvet you can buy is usually 15 tog, although we have seen some all-season duvets (where two separate duvets of differing togs are combined into one warmer duvet) offering a combined warmth of up to 18 tog.

After much testing, we think 13.5 tog is best tog duvet for winter, with most of our testers finding 15 tog can retain heat a little too much during the night and lead to overheating.

CHILLY NIGHTS - Our duvets are made with a soft hollow fibre filling coupled with a soft touch cover giving you that cosy comfy feeling so you can enjoy great night’s sleep all night long. Microfibre– the 'luxury' version of hollowfibre, a microfibre fill is made of much finer strands of polyester resulting in a very lightweight duvet with a, yes, more luxurious feel. Some compare microfibre to the feel of down, but it has the upside of not running the risk of animal cruelty. However, again, being made of synthetics, the environmental impact of production and disposal is a concern. Like hollowfibre, microfibre can also cause overheating. 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.
