Most people spend more time choosing sheets than choosing the quilt that goes inside them. Yet the quilt has more influence over sleep comfort than almost any other element of the bed. It determines how warm you sleep, how well heat escapes, and whether you wake in the night feeling too hot, too cold, or just right.
The difficulty is that there is no single best quilt. The right one depends on how your body regulates temperature, where you sleep, what time of year it is, and whether you prefer a light, airy feel or a heavier, more enveloping weight. What works well for one person can genuinely fail another — and both people might be sleeping in the same room.
This guide covers the four main filling types — goose down, Australian wool, cotton, and microfibre — what each one does well, and how to match your choice to how you actually sleep.
Why the Quilt Matters More Than You Think
The quilt's job is not simply to provide warmth. It is to manage the thermal environment between your body and the bedding — holding enough warmth to keep you comfortable while allowing excess heat to escape. When this balance is right, sleep tends to be deep and uninterrupted. When it's wrong, the signs are familiar: waking at 2am feeling too hot, pushing the quilt off and then pulling it back, or waking feeling less rested than the hours of sleep would suggest.
The material the quilt is filled with determines how well it manages this balance. Different fillings behave differently when it comes to heat retention, breathability, moisture management, and how the weight feels against the body. Understanding these differences is the clearest path to a better night's sleep.
Before you choose: three questions worth asking
Do you sleep warm or cool?
Warm sleepers need high breathability. Cool sleepers can tolerate more insulation. Most people don't know the answer until they've slept badly a few times.
Do you run hot at different points in the night?
Some people sleep fine initially but wake warm around 3am. This usually points to a breathability issue rather than an insulation one.
Do you prefer light or weighted?
This is personal preference rather than performance. Some people sleep better under a heavier quilt; others find lighter is more comfortable regardless of temperature.
Goose Down: Light, Warm, and Insulating
Down quilts are the most well-known premium option, and the reason is simple: the natural cluster structure of down traps air exceptionally well, creating significant warmth from very little weight. A high-quality down quilt can be noticeably warmer than alternatives without feeling heavy on the body.
The trade-off is breathability. Down's strength is its ability to hold warm air in — which is also what can make it less ideal for warm sleepers. In a cool room with good ventilation, down performs well. In a warmer room or for someone who generates significant body heat, it can trap heat rather than releasing it.
Down is best suited to people who want warmth without weight, sleep in cooler environments, and don't have issues with nighttime overheating. Browse the Chamonix collection if this sounds like your sleep style.
Australian Wool: Temperature-Regulating and Breathable
Wool quilts work differently from down. Rather than simply insulating, wool fibres actively respond to body temperature — absorbing excess heat and moisture when the body produces them, and releasing both back as conditions change. The result is a more consistent thermal environment throughout the night than most other filling types provide.
This makes wool particularly well suited to people who experience temperature fluctuations during sleep — warm in the early part of the night and cooler toward morning, or the reverse. Wool handles both directions, which is why it is often described as suitable year-round. It's also a strong option for people who wake in the night feeling warm but don't want to sacrifice warmth in cooler conditions.
The feel is slightly denser than down — more substantive, less cloud-like. For some sleepers this is preferable; for others, the lighter feel of down is the priority. Explore the Holborn wool quilt collection to find the right warmth rating for your climate.

| Natural fibre | Yes | Yes | Yes | No |
Cotton: Light Coverage and Easy Layering
Cotton quilts sit at the lighter end of the warmth spectrum, making them well suited to warmer climates, warmer sleepers, or use during the warmer months in variable climates. They are breathable, familiar, and easy to care for — and they layer well, meaning a cotton quilt can be combined with a lighter blanket as temperatures drop rather than needing to be swapped out entirely.
The practical appeal is flexibility. For households where bedding needs to adapt across seasons without significant upheaval, a cotton quilt as the base layer allows seasonal variation to be handled through what goes on top of it rather than underneath. See the Willow collection for cotton quilt options.
Microfibre: Consistent and Low Maintenance
Microfibre quilts are the most practical and lowest-maintenance option — easy to wash, consistent in structure, and typically the lowest cost entry point. They provide a reasonable level of warmth with a smooth, even feel, and they hold their shape well over time.
The significant limitation is breathability. Synthetic fibres do not respond to changes in body temperature, and they tend to trap moisture rather than releasing it. For sleepers who are prone to waking warm or who perspire during the night, microfibre will compound the problem. As a primary quilt for most people, it underperforms natural alternatives in ways that become more apparent over time.
Where microfibre works well is as an additional layer in genuinely cold conditions, or as a transitional option while trialling a different primary quilt. Browse the Cosybrooke collection for microfibre options.
How to Choose What's Right for You
If you often wake warm or push the quilt off during the night — prioritise breathability over warmth. Our Holborn wool quilt is the strongest performer here, followed by a cotton option. A lighter tog rating in wool will outperform a heavier microfibre quilt for most warm sleepers.
If you feel cold when you first get into bed but warm up significantly through the night — wool's ability to regulate in both directions makes it the most practical choice. The Holborn collection will keep you warm at the start and manage excess heat as it builds.
If you sleep in a consistently cool room and want maximum warmth for minimal weight — down is the strongest option. The warmth-to-weight ratio is unmatched, and in a cool, well-ventilated room, the breathability trade-off is less significant. See the Chamonix collection.
If you live in a warmer climate or sleep warm year-round — a lightweight cotton quilt from the Willow range used alone in summer and combined with a blanket in cooler months is a practical approach that avoids the need to own multiple full quilts.
Building a Balanced Bed
A quilt performs best when the bedding around it supports rather than works against it. The sheets and pillowcases in direct contact with your body have a significant effect on the overall thermal experience — synthetic or poorly breathable sheets can negate the benefits of a more breathable quilt, while natural fibres allow the quilt to do its job more effectively.

Stonewashed Cotton in Blush. Pre-washed softness with natural breathability. Shop Stonewashed Cotton →
Our Pure Linen range provides the highest breathability at the sheet level — the hollow-fibre weave allows air to circulate continuously, supporting temperature regulation regardless of which quilt you choose. It pairs naturally with both wool and down quilts without adding thermal resistance.
For those who prefer a softer starting texture, our Stonewashed Cotton range in Blush or Slate offers pre-washed softness with good breathability — a comfortable match for cotton or lighter wool quilts, particularly in moderate climates.
What the Right Quilt Actually Feels Like
The right quilt is not particularly noticeable. It does not call attention to itself by feeling too warm or too cool. It simply allows sleep to happen — and to continue happening, through the night and across seasons, without needing adjustment.
When the quilt is wrong, sleep is lighter, waking more frequent, and mornings feel less recovered. The cause is often the last thing considered, because the quilt has been in place long enough that it no longer registers as a variable. Reconsidering it is often one of the clearest sleep improvements available — at no cost to routine.
Explore our full quilt range — Chamonix for goose down, Holborn for Australian wool, Willow for cotton, and Cosybrooke for microfibre — or pair any quilt with our Pure Linen or Stonewashed Cotton sheets for a bed built to work with your body rather than against it.
