Finding the perfect duvet is about more than just climbing into something cozy at the end of the day. The right duvet tog rating can be the difference between waking up feeling refreshed - or tossing, turning, and fighting your partner for extra covers at 3am.
At Piglet in Bed, we believe that restful sleep starts with the right layers. That’s why we’ve put together our ultimate guide to duvet togs, designed to help you choose the one that’s just right for you. And in honor of Wool Month this October, we’re shining a spotlight on wool’s natural comfort and breathability, and the many qualities that make it a classic choice for better sleep.
What Does a Duvet Tog Mean?
A duvet’s tog rating is a measure of how well it traps heat, ranging from 1 to 15. The higher the tog, the warmer the duvet feels. Choosing the right tog for the season is key to uninterrupted, restful sleep. Here’s a quick breakdown:
-
Low tog (1-4.5): Lightweight, airy and ideal for summer or naturally warm sleepers. We recommend our Lighter duvets, made from natural Merino wool or British wool, for breathable comfort.
-
Medium tog (4.5-8): A versatile choice for spring and autumn nights. Depending on whether you prefer a little more or a little less warmth, our Lighter or Warmer wool duvets are perfectly suited.
-
High tog (10-15): Snuggly, insulating and ideal for chilly winters or draughty bedrooms. Our heavier Warmer duvets, crafted from Merino wool or British wool, provide snug comfort throughout the coldest months.
How to Match Your Duvet to Your Bedroom Temperature
It’s not just the season you should think about - your bedroom environment plays a big role in how warm or cool you’ll feel under the covers.
-
Warm bedrooms (68°F+): Stick with a 1-4.5 tog duvet (our Lighter option) to avoid overheating.
-
Average bedrooms (64–68°F): A 7-10.5 tog duvet (Lighter or Warmer, depending on exact temperature and preference) will keep you comfortable through most of the year.
-
Cool bedrooms (61°F or lower): Opt for a 12–15 tog duvet (our Warmer option) for maximum warmth in winter.
Consider Your Sleep Style
No two sleepers are the same, which is why your habits matter as much as the tog:
-
Hot sleepers: Choose a lower tog year-round, even in winter.
-
Cold sleepers: Go for a higher tog to keep the chill at bay.
-
Night sweats or hormonal changes: A lower tog duvet made from breathable natural fibers helps regulate your temperature.
Why Natural Materials Make All the Difference
Not all duvets are created equal. At Piglet in Bed, our duvets are filled with Merino wool and British wool, chosen for their incredible thermal properties. Wool is a natural thermo-regulator, which means it works with your body to keep you warm in winter and cool in summer - without the bulk of synthetic alternatives.
Unlike synthetics, wool duvets aren’t rigidly defined by tog rating. Our duvets come in two options:
-
Lighter weight (200gsm): Equivalent to 4-6 tog, ideal for summer or warm sleepers.
-
Warmer weight (350gsm): Equivalent to 8-10 tog, perfect for fall, winter and cooler bedrooms.
Both are encased in soft, breathable cotton, making them beautifully lightweight yet snug.
The Benefits of Wool-Filled Duvets
-
Breathable & moisture-wicking: They help prevent overheating and keep night sweats at bay.
-
Naturally hypoallergenic: They’re resistant to dust mites, making them a healthier option for sensitive sleepers.
-
Sustainable & durable: Wool is renewable, biodegradable, and built to last - so you’ll enjoy cozy sleep for years to come.
Choosing the right duvet tog is about more than temperature - it’s about comfort, sustainability, and the way you like to sleep. Whether you run hot, run cold, or share a bed with someone who does the opposite, our collection of natural wool duvets has an option to suit every season and every sleeper.
