duvet buying guide

the sleep summary

• A duvet can be filled with two types of filling, either natural fillings such as feather or down, or synthetic fillings such as microfibre of hollowfibre.

• Down duvets are lightweight, breathable and help regulate body temperature, but are more expensive and can be harder to care for, whereas synthetic duvets are more affordable and easy to care for but not as breathable and can lose its fluffiness over time.

• A duvet tog refers to it’s warmth measurement, with a 1.5-4.5 tog being ideal for summer and hot sleepers, a 7-10 tog being the perfect middle ground and suitable all year round, and 10.5-15 tog perfect for cold sleepers and throughout the colder months.

• The best duvet is the one that suits your personal preferences, and when choosing a duvet you should consider whether you’re a hot or cold sleeper, if you suffer from allergies, the thickness you prefer and whether you prefer a heavier or lighter option.

• You should take care of your duvet and regularly clean it. Most duvets are machine washable so you should aim to do this at least once a year to keep it fresh, but always check the care label to make sure you can.

Choosing the right duvet can make all the difference to your sleep. While it might not get as much thought as your bed or mattress, the right duvet wraps you in comfort, keeps you cosy and helps create a breathable sleep environment. We’re here to help you find the perfect duvet for dreamy nights. From togs and fillings to the different types we offer, we’ll guide you through everything you need to know. Plus, we’ll share tips on how to care for your duvet, so it stays just as inviting as the first night you snuggled under it.

what is a duvet?

A duvet is a soft, quilted blanket filled with materials like feathers, microfibre or down. It’s designed to wrap you up in warmth and comfort as you drift off to sleep. You can easily change the look of your duvet with duvet cover sets to match your bedroom and create the perfect sleep sanctuary.

how to choose a duvet

When choosing a duvet, you need to consider more than just how warm you want to be at night. Things like tog ratings, the type of filling, size and care requirements will all affect how comfortable your duvet feels and matches your sleep style. Understanding these different choices will help inform your decision and get you on the road to a comfortable night’s sleep.

types of duvet filling

There are two types of duvet fillings you can opt for, so you can figure out the best duvet filling for your needs. Natural and synthetic both offer several pros and cons, depending on your preferences and budget. Let’s take a look into both:

natural fillings

Naturally filled duvets usually use down or feathers to maximise plumpness for the ultimate comfort.

• Feather duvets use the outer layer of feathers on a bird’s wings. These duvets are more budget-friendly and offer fantastic support while being more allergy-friendly.

• Down duvets use the undercoating of feathers found on a bird’s chest. Down duvets are more expensive, but they offer fantastic insulation and are lighter and more breathable.

You can also find wool and silk duvet options available, which are fantastic for their moisture-wicking properties, breathability and allergy-friendliness.

synthetic fillings

Synthetic fillings tend to be a lot more affordable and easier to maintain, but they’re unlikely to last as long as naturally filled duvets. Often, synthetic duvets use microfibre or hollowfibre as filling, which are made up of processed polyester to mimic the feeling of down or feather duvets.

• Microfibre uses extra fine polyester fibres, adding a lighter and more luxurious touch. You’ll also find that microfibre duvets are much more breathable than hollowfibre while offering a more aesthetically pleasing look when laid over the bed.

• Hollowfibre is a lot thicker and plumper, without being too heavy. These duvets tend to last longer and are hypoallergenic, making them ideal for sensitive and allergy-prone sleepers.

Don't forget, there are also eco-friendly alternatives available, like our sustainable duvets that use recycled fibres for planet friendliness. These are also a great hypoallergenic option.

down vs synthetic duvet pros and cons

what is a tog rating for duvets and which do you need?

What is a duvet tog and why does it matter? A duvet tog refers to the warmth measurement of a duvet; the higher the rating, the warmer it is. This is just as important as the filling when buying a duvet as it ensures proper temperature control all year long. Here’s our quick overview of duvet togs:

• 1.5–4.5 tog: Low tog ratings, ideal for summer and the best duvet for hot sleepers

• 7–10 tog: Medium tog ratings, suitable all year round

• 10.5–15 tog: High tog ratings, perfect for winter cosiness and the best duvet for cold sleepers

The most common tog rating in the UK is a 10.5 as it reduces the need to switch it out as each season hits. For another perfect middle ground, some duvets offer interchangeable layers, making them super versatile. Shop our seasonal duvets to stay extra comfy when the weather changes.

can I use the same duvet year-round?

Yes – one of these tog options may suit you year-round, especially our most popular 10.5 tog which is designed to be used throughout all seasons.

duvet sizes explained: the perfect fit matters

The size of your duvet matters just as much as its tog rating and filling. While most duvets are designed to match standard mattress sizes, there are instances where you may want to go bigger or smaller. Snuggling up with the right-sized duvet can make all the difference for a cosy, uninterrupted night’s sleep. Here’s a look at the UK standard duvet size guide:

• Single: 135 x 200 cm (53 x 79 inches) – ideal for standard single beds

• Double: 200 x 200 cm (79 x 79 inches) – fitting most double mattresses

• King: 225 x 220 cm (89 x 87 inches) – for king-size beds

• Super King: 260 x 220 cm (102 x 87 inches) – suited for larger, super king mattresses

Choosing a duvet that matches your mattress size means it's less likely to overhang or leave you feeling cold due to being too small. If your bed is uniquely shaped, a custom-sized duvet might be the way to go. For children, look for lightweight, smaller duvets to keep them safe and snug through the night.

Top tip: Upsizing your duvet can make your bed feel cosier and help you drift off without disruptions. If you share a bed, a king-size duvet on a double bed could be the key to avoiding those midnight tug-of-war games. Plus, the extra draping effect adds a touch of luxury, giving your bed that indulgent, hotel-style plush aesthetic.

what’s the difference between a duvet and a comforter?

A duvet is usually made up of two elements: the duvet and its cover. A comforter, on the other hand, usually sits on top of a duvet to be used as an extra layer of warmth; a much more popular addition to beds in America.

preference is everything

Don’t forget, your preference also plays a big role in what duvet you purchase. It’s not about the best duvet; it’s about the best duvet for you. Here’s what you should consider:

• Hot or cold sleepers: Finding the right material and tog rating will help you achieve that perfect temperature. Hot sleepers might prefer lightweight options, like a low or medium tog with microfibre or feather filling. If you’re always chilly, go for 10.5+ togs with cosy down or hollowfibre fillings to stay toasty.

• Allergy sufferers: If you’re allergy-prone, stick to hypoallergenic duvets and invest in dust mite treatments for added peace of mind. Materials like hollowfibre and feather fillings naturally repel dust mites, helping you breathe easier.

• Weighted options: Do you find weighted blankets calming? You’ll likely find a heavier duvet offers the same benefits. Not only may you feel a strong sense of comfort, but mimicking the likes of a hug can be very therapeutic.

• Thicknesses: The thickness of a duvet can contribute to your comfort levels too. Maybe you don’t like duvets bunching up near your face while snoozing, making thicker duvets of 10.5+ togs unsuitable.

making sustainable choices

Sustainable living is becoming more and more common, with many people making greener choices in everyday purchases, including one’s bed set-up. With that in mind, there are several eco-friendly duvet material options available. Eco-friendly duvet fillings include natural fibres like wool, down and bamboo. By choosing these natural fillings, you’re making an environmentally conscious choice without compromising on comfort. For extra confidence, look out for certifications such as OEKO-TEX (safe textiles) and GOTS (Global Organic Textile Standard).

time to budget

Once you know what type of duvet you’re looking for, it’s time to match it to your budget. How much you spend on a duvet comes down to personal preference; by investing, you’ll likely be given longer-lasting quality, whereas a budget-friendly option may need to be replaced after 1-2 years. Don’t worry, we always offer affordable and quality-assured duvet options at Silentnight, giving you extra peace of mind.

how to clean and care for your duvet

Now you have the ingredients for a duvet that ticks all your boxes, it’s time to focus on keeping your duvet fresh and clean for years to come. Below are some commonly asked questions to give you an idea of the level of maintenance for each type of duvet.

can you wash a duvet?

Yes – all duvets are machine washable, but the cycles may differ depending on the filling. Wash your duvet at least once a year to maintain its freshness and hygiene.

how do you wash a duvet in a washing machine?

Synthetically filled duvets can easily be popped into the washing machine on a gentle cycle at 40°C and using a mild detergent. Down or feather-filled duvets are also machine washable, you may just need a larger drum. For natural fillings, we recommend a delicate cycle at 30°C with a down-friendly detergent. Always check the label to make sure yours is compatible with a washing machine.

how do you dry a duvet?

Duvets can be dried in several ways – including on the washing line or in a tumble dryer on low heat. Always opt for air-drying if possible as this will prevent the filling from clumping. Please note, you should always check the care label of your duvet for instructions.

how often should you replace your duvet?

You should replace your duvet every 5-10 years, depending on how much it’s used and the type of filling it has. Synthetic versions tend to need replacing sooner than naturally filled duvets as they lose their shape much faster.

when should you replace your duvet?

You should replace your duvet when lumps or unevenness form within the filling, or if you experience loss of warmth, plumpness or persistent stains and odours.

how do you store a duvet

Do you own spare duvets for when the seasons change? Storing them in the right way will ensure they stay clean, fresh and ready to be used. We recommend:

• Using breathable storage bags to prevent unwanted odours and moisture build-up.

• Keeping duvets in a cool, dry place so that direct sunlight doesn’t impact their quality and dampness doesn’t cause mould.

• Ensuring your duvet is completely clean and dry before you store it to avoid mould or mildew build-up.

how do you put on a duvet cover?

There are plenty of ways to make this task easier, but a good hack is to turn the duvet cover inside-out, then slip your hands into the far corners. Grab the matching corners of your duvet, flip the cover over, and shake it gently into place. Once it’s all snug, fasten it up.

what tog duvet for winter?

For those chilly winter nights, a duvet with a tog rating of 10.5 to 15 is perfect for keeping you cosy without the risk of waking up shivering. It's the ideal layer for hibernation-worthy sleep.

what tog duvet for toddler?

The ideal tog rating for a toddler's duvet depends on their age, the temperature of their room, and the size of their bed. Usually, a toddler’s duvet should be light at a 3.5-4 tog rating, increasing to 7.5-9 as they grow.

what do you do with old duvets?

When it’s time for a duvet upgrade, think sustainably. Old duvets can be donated, upcycled into cushions or pet beds, or recycled at textile banks. Giving them a second life is as comforting as a good night’s sleep.
