What’s your favourite bedding for staying cool? Sheets, pillows & duvets!

If you’ve ever woken up in the middle of the night feeling like you’ve slept inside a greenhouse, you’re not alone. At Linen Bay, this is exactly where our story began, not in a showroom, but in that slightly desperate, 3am moment when nothing feels comfortable and sleep slips away.

We’re a small team, and everything we make comes from real experience. So rather than a list of trends or “cooling technology”, this is our honest answer to the question we hear all the time:

What bedding actually keeps you cool at night?

A very real 2:47am moment

We remember one July night vividly. Waking up at 2:47am, not because of noise or light, but because the bed felt unbearable.

The duvet felt damp.
The sheets were clinging.
The air felt still and heavy.

The only solution? Standing by an open window, half-asleep, hoping for a breeze. The rest of the night was spent lying on top of the duvet, starfish-style. Not exactly restful.

That moment was a turning point. Because it made one thing very clear:

Not all bedding is created equal, and some of it actively makes your sleep worse.

What actually changed everything

The shift didn’t come from gadgets or “cooling” claims. It came from something much simpler: choosing the right natural fibres and weaves.

Linen: the first “wow” moment

Linen was the first time we noticed a real difference.

• It doesn’t cling to your skin
• It allows air to move freely
• It stays comfortable even when the room is warm

Instead of waking up overheated, we simply… slept through.

Cotton percale: the quiet hero

Then came cotton percale.

• Crisp, matte finish
• Light and breathable
• Consistent, year-round comfort

It’s not flashy, but it’s incredibly reliable, especially if you tend to run warm.

If you’re still working out what suits you best, we’ve gone into more detail in our guide to choosing the right bedding for your sleep style.

Our current bedding setup (and why it works)

After years of testing (and many uncomfortable nights), this is what we now sleep on:

• Sheets: Linen fitted sheet + cotton percale flat sheet
• Duvet: 4.5 tog in summer, 9 tog in winter
• Pillows: Medium-firm down alternative
• Topper: Breathable cotton (no foam)

It’s a combination that allows airflow, avoids heat traps, and adapts to the seasons without overcomplicating things.

What doesn’t work (our honest take)

There’s a lot of noise in the bedding world. Here’s what we’ve found doesn’t live up to the promise:

• Memory foam (pillows, toppers, mattresses)
  Holds heat. Great for support, not for cooling.
• Polyester “cooling” sheets
  Feel cool for about 10 seconds… then trap heat.
• Sateen cotton
  Beautiful and smooth, but the tighter weave runs warmer.
• Cheap bamboo blends
  Often more marketing than substance.

And perhaps most importantly:

Soft doesn’t always mean cool.

Why we focus on linen and cotton

At Linen Bay, we didn’t choose our materials because they’re trendy. We chose them because they’re the only ones we consistently sleep well in.

• They’re naturally breathable
• They don’t rely on synthetic coatings or gimmicks
• They age beautifully, getting softer over time
• They’re better for both comfort and longevity

If you want to keep them feeling their best for years, we’ve shared simple tips in our guide to how to care for linen and cotton bedding.

The real turning point for us was realising:

• Cooling bedding isn’t a feature, it’s a result of the right fibre and weave.

And yes we sleep on our own products every night. Because we wouldn’t offer anything we wouldn’t happily use ourselves.

What our customers tell us

The most meaningful feedback we hear isn’t about thread count or fabric specs, it’s about sleep.

One customer told us:

“I stopped waking up drenched at 3am, I didn’t think bedding could fix that.”

Another said:

“My partner finally stopped kicking the duvet off every night.”

Those are the moments that matter.

The real-world ranking (no fluff)

If staying cool is your priority, here’s our honest order:

1. Linen – unmatched airflow, never clingy
2. Cotton percale – crisp, breathable, dependable
3. Bamboo – can feel cool, but varies widely
4. Cotton sateen – smoother, but warmer
5. Polyester/blends – heat-trapping

And one myth worth clearing up:

Higher thread count doesn’t mean cooler.
In fact, it usually means the opposite.

For breathability, the sweet spot is typically 200–300 thread count percale.

Pillows and duvets matter more than you think

Pillows

Your pillow can quietly hold a lot of heat.

We prefer:

• Down alternative (light, breathable, supportive)

We avoid:

• Memory foam
• Gel-infused foams
• Dense latex

Duvets & layers

• 4.5 tog is ideal for warm sleepers
• Switch seasonally if you can
• During heatwaves? Skip the duvet entirely and use a linen flat sheet

A flat sheet isn't the only option, though. Many people now choose to sleep without one altogether, using a breathable duvet cover as the layer directly against their skin. We've looked at what people use instead of a top sheet and the different options that work across the seasons.

Sometimes less really is more.

Simple ways to sleep cooler tonight

You don’t need to replace everything to feel a difference.

Try this tonight:

• Let your feet stick out of the covers
• Take a lukewarm shower before bed
• Keep curtains closed during the day
• Use a fan facing out the window to pull hot air out

One small upgrade:

Switch your pillowcase to linen or percale.
It’s a small change, but you feel it immediately.

If you’re ready to go a step further, exploring our range of breathable cotton bedding sets can make a noticeable difference to how cool and comfortable your bed feels.

A few unexpected tricks:

• Chill your top sheet in the freezer for 10 minutes
• Lightly mist sheets with water + eucalyptus
• Flip your pillow, there’s always a cooler side

Final thoughts

If there’s one thing we’ve learned, it’s this:

Good sleep doesn’t come from complexity, it comes from simplicity done well.

Natural fibres. Breathable weaves. Thoughtful choices.

At Linen Bay, we’re not trying to reinvent bedding. We’re simply trying to make it feel right, cool, comfortable, and quietly dependable, night after night.

And if you’ve ever found yourself standing by an open window at 2:47am, we hope this helps you sleep a little easier.
