Sleep Is Big Business Now. Your Duvet Isn't.

Sleep used to be pretty much free.

You went to bed. You got up. If the sleep was poor you had a bad day, and nobody sold you anything about how to improve it.

Then somewhere around 2015 sleep became an industry. Apps and rings that score your night out of a hundred. Apps that play brown noise at you. Mattresses that cost more than a decent second-hand car (and a few that cost 10x that). A whole genre of advice that has managed to convince perfectly well-rested people they are doing it wrong.

We sell wool duvets. You'd expect us to join in.

We're not going to.

The Trouble With Sleep Optimisation

Most of what's sold as sleep optimisation is noise. And the tiresome thing about noise is that it often drowns out whats worth hearing about.

One of those things is lying on top of you for eight hours a night.

Almost nobody talks about it, because a duvet is a dull product you buy a few times in your adult life. There's no subscription in it. No app. Nothing to score. Nobody has ever posted their duvet on Instagram (have they?)

That's rather the point.

What's Actually Going On Under There

Your body already knows how to do this.

Core temperature drops as you fall asleep and stays low through the night. Your body manages that drop itself — with sweat (yes, we all do it), with blood flow to the skin, with a system that has had a very long time to get good at it.

It doesn't need help. It needs not to be interfered with.

Which makes a duvet's job much narrower than the marketing suggests. Not to warm you. Not to cool you. To sit there and let your body get on with regulating itself, while keeping hold of the heat you do want.

A duvet that traps moisture against your skin is interfering. A duvet that holds heat when you've turned over and stopped needing it is interfering. Polyester wadding does both. That's the three-in-the-morning leg out of the covers.

Why Wool, Specifically

Wool fibres are crimped. Not smooth like a synthetic filament — kinked, springy, tangled. Those kinks hold pockets of still air, and still air is insulation.

It's the same reason a natural wool fleece keeps a ewe alive on a Scots mountain (or Bodmin Moor) in February.

That ewe keeps the same fleece through much of the summer. One coat, both jobs, all year . This which tells you wool isn't insulation so much as regulation: still air held in the crimp, moisture moving out through the fibre, in either direction as required.

A ewe wearing a polyester fleece would manage February well enough, but in August it would kill her.

Wool is also hygroscopic, which is a long word for a simple habit: it takes moisture into the fibre itself rather than letting it sit on your skin. You lose a surprising amount of water overnight, through perspiration and breathing, even when you're cold. Wool absorbs it and releases it again as conditions change. Synthetics don't. The moisture has nowhere to go but back onto you.

Which is why people describe wool bedding as feeling dry rather than feeling warm.

Warm is easy. Dry is the difficult bit.

The Unglamorous Advantages

Wool is naturally dirt and dust resistant. It doesn't hold on to smells — it repels them rather than storing them. So a wool duvet needs mostly only airing. And very rarely does it need cleaning. A couple of hours over a line on a decent day and it's done.

That sounds like a small convenience. It's actually the whole economic argument.

A duvet you rarely wash is a duvet that doesn't degrade. A duvet that doesn't degrade is one you're not replacing every four years. Buy once and buy well isn't a slogan we  use to justify a price — it's the only version of sustainability that survives contact with maths. You can learn about the Life Cycle Assessment (LCA) of wool here

And when a wool duvet finally reaches the end, decades on, it goes into the ground and disappears naturally. Nothing in nature was designed to be disposable. Everything does its work and then returns. We didn't come up with that idea. We've just noticed that the fibre industry spent seventy years pretending it didn't apply to them.

The Bit That Matters To Us

There's a kind of sustainability that rarely gets mentioned, because it's hard to put on a swing tag: whether the industry itself survives.

We're on the edge of Bodmin Moor, among farms where the clip has, in some years, been worth less than the cost of shearing. That is an absurd situation. Especially for a valuable natural product. It isn't fixed by a certification scheme. It's fixed by people buying wool.

So our new duvets are British through and through. British wool, certified traceable back to the Scottish farms it came off, and made up at a mill in Yorkshire that holds the British Wool Crook Mark. 

We are proud of the product. It took us years to arrange: superb quality, and genuinely made in the UK. It is not the cheapest way to make a duvet, but we think it is the best one, and the only honest one. It also lets us sleep at night, which is after all the business we are in.

We're Not Pretending

No duvet will give you a perfect night's sleep.

You may get one of those because you had some fresh air and went to bed at a sensible hour, didn't drink four coffees after lunch or finish on whisky. You may not.

But of everything sold as a sleep improvement, the duvet is the one with the least nonsense attached, and the longest life. Choose it once choose it well. It costs less than the mattress and about what you'd pay for the ring. Then don't think about it again for twenty years.

We spend something like twenty-six years of our lives asleep.

Worth getting the boring bit right.
