Product Information

Emily Attwood, founder of sleep-brand scooms agrees, ''We’d always advise a 9 tog to 13.5 tog for the winter months as this is ideal and will keep you warm. If your house is always on the warmer side, then a 9 tog duvet would probably suit you better throughout the winter months, and you wouldn’t want to go any higher. This will prevent you from overheating which can disrupt your sleep.' 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.

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. 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. 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.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. Buy it if: you're looking for the very best duvet for a great night's sleep. This wool-filled duvet is an investment, but we've tried and tested some of the best winter duvets on the market, and in our opinion, this is the cream of the crop. It's the warmest we've come across, keeping our testers warm and toasty throughout the night without any of the overheating or night sweats that occurred with other high tog options. That's thanks to the naturally thermoregulating properties of wool that allow moisture to escape whilst still providing insulation. Handmade in Yorkshire using 100% traceable British Cheviot wool and certified organic cotton this is also a great eco-friendly option, with wool completely biodegradable. 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.

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.

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.

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.

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.
