quilt or duvet filling: the question that settles everything else

Let’s start here, because everything that follows depends on this answer. When someone searches for how to choose the right quilt they usually have one of these two things in mind, and they are quite different.

A quilt is a padded piece that is placed directly on top of the bed, without a cover. It is the visible piece, the one that dresses the bedroom. And it is worth clearing up a common misunderstanding here: not all quilts are printed. We have both printed and plain, so you can choose a simple, understated colour or a design with character; in both cases it is still a quilt, because what defines it is that it goes on top.

A duvet filling is the piece that goes inside a duvet cover. You never see it, because the duvet cover provides the design. Its only job is to keep you warm, which is why it comes in different filling weights and in a plain colour: there is no point printing something that stays covered.

The difference is not the print. The quilt goes on top; the duvet filling goes inside.

So, which one should I choose?

If you want the simplest option, choose the quilt: one piece, no fuss, and you can pick plain or printed to suit your bedroom. If being able to adjust the warmth matters to you, or you like changing the design each season, a duvet filling with a duvet cover is the system for you. The quick rule: want to control the warmth and change the look often? Duvet filling. Want to make the bed in a minute? Quilt.

filling weight: the difference between sleeping well and throwing the covers off all night

The quilt filling weight is measured in grams per square metre and simply tells you how much fibre is inside. More grams means more warmth. It sounds obvious, but this is where the most common mistake happens: assuming you need the highest weight to avoid feeling cold. A duvet filling that is too warm for your room will have you waking up uncovered at three in the morning, which disrupts sleep just as much as being cold.

The right figure does not depend only on the season: it depends on the actual temperature of your bedroom. A centrally heated bedroom at 21°C does not need the same filling weight as an uninsulated bedroom in an older flat. Before choosing, think about how you sleep: if you are always sticking one foot out, go for the lighter option.

The three filling weights of our duvet fillings

The 250 g is the mid-season option: spring and autumn, or all winter if your bedroom is well heated. The 450 g is for genuinely cold nights, when you appreciate a warmer bed. And the 4 Seasons is actually two separate fillings, 120 and 250 grams, which you can use separately or fastened together: the lighter one on its own in summer, the 250 g one in mid-season and both together —370 grams— when winter really sets in. If you do not want to store two different fillings, this is the answer.

And what filling weight does the quilt have?

Our quilt comes in 300 grams, a single filling weight designed precisely for the colder months. It strikes the right balance between warmth and lightness, keeping you cosy without feeling oppressive and working well for everyday use in almost any bedroom. Because there is only one weight, there is nothing to decide here: choose the design —plain or printed— and the size, and you’re done.

materials: microfibre outside, hollow fibre inside

The quilt material is what determines whether warmth turns into clammy, uncomfortable heat or a dry, comfortable night. Our duvet fillings have a microfibre outer y siliconised hollow-fibre filling, and it is worth understanding what that means, because it is not just marketing.

Hollow fibre is exactly what it sounds like: each filament contains air. That air provides the insulation, not the weight, so you get warmth without a heavy load on top of you. The siliconised treatment allows the fibres to glide over one another instead of tangling, which gives you two benefits you notice every night: it stays fluffy instead of clumping in the corners, and it is fully breathable, so body moisture can escape instead of becoming trapped between you and the bedding.

Fluffy and lightweight

Hollow fibre keeps you warm thanks to the air inside it, not through weight. Comfort without feeling weighed down.

Breathable

It allows body moisture to escape, helping the bed stay dry throughout the night.

Hypoallergenic

As a synthetic fibre, it is hypoallergenic. A reassuring option for sensitive skin and airways.

Why fibre instead of down

It is the comparison that always comes up, so let’s address it. Natural down is very warm and very light, that is true. But it has three drawbacks that matter in everyday use: it is difficult to wash at home, can be problematic for allergy sufferers and costs considerably more. Modern siliconised hollow fibre comes surprisingly close in feel and wins on practicality. That is why we use it: you can wash it in your washing machine, it is suitable for allergy sufferers and stands up well to life in a home with children or pets.

what size you need for your bed

Here is the other classic mistake: buying the size that matches the width of the mattress. It does not work like that. Both the quilt and the duvet filling need to be wider than the bed so they can fall down the sides and keep you covered when you move. If the size is too tight, you will spend the night pulling the bedding back over yourself.

Duvet filling sizes

Eight sizes, for beds from 80 to 200 cm wide. Note that there are two options for 180/200 cm beds: the 260×240 size gives you more drop, and it is the one I would choose if your mattress is deep or two people share the bed.

Quilt sizes

Three sizes, each covering several bed widths, and the same measurements for both plain and printed designs. Because this is the visible piece, the drop also matters aesthetically: the 260 cm length is designed to sit well at both the foot and the head of the bed.

One tip that can save a return: if you are between two sizes, always choose the larger one. A little extra fabric falls elegantly and keeps you better covered; a little too little is noticeable every night. And if you use a mattress topper or your mattress is more than 30 cm deep, there is no question: choose the larger size. You can find the full details in our size guide.

how to build your winter bed

You have the pieces. Now here are the two combinations that genuinely work, depending on what you are looking for.

If you choose option B, remember that the cover should match the size of the filling, not the size of your mattress. And do not worry about the filling moving around inside: our covers have a fastening and the fillings hold their shape thanks to the siliconised treatment.
