Simba Hybrid 3-in-1 Duvet review: Design 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. 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. 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

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. 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. 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. First up, it's synthetic fillings. These duvets are filled with manmade fibres, like polyester and polymide that are made from petroleum-based plastics.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.

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. Each All Seasons duvet consists of a lighter summer duvet and a warmer winter duvet. Use one on its own in summer, spring & autumn and when the temperature falls you can fasten them together for a super warm winter duvet. All seasons duvets can be clipped together either with press studs or buttons, depending on which all seasons option you decide on.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. 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. Then there are the more traditional, natural fillingsto consider. These range from all types of feathers and down to wool filling. The covers on both duvets are made with cooling cotton, with Simba being part of the Better Cotton Initiative (BCI), which makes cotton production better for the people who produce it and the environment it grows in. The top of the cover is 100% cotton with Stratos cooling technology, while the bottom of the cover is 55% cotton and 45% modal. 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.
