Free UK delivery and free UK returns
Elastic all the way round | Deep pockets that stay on
Almost sold out
See it on a real bed
Not a styled photoshoot. A made bed, a slept-in bed, and the corners in the morning.
Most cooling sheets are measured for one second. Q-Max records how cool a fabric feels the instant your skin touches it. Every decent fabric passes that test, which is why almost every brand prints the number and stops there.
The hour that matters is the fourth one. A fabric that only feels cold on contact stops doing anything once your body and the sheet have met in the middle. A fabric that keeps moving heat away carries on through the night.
And there is a second problem nobody mentions. Fabrics that move heat well are smooth, and smooth fabric slides. Read the two-star reviews on any cooling sheet and the same sentence comes back: it will not stay on the mattress. We kept the fabric and changed the fit instead.
1x fitted sheet with deep pockets and elastic all the way round
2x pillowcases in the same fabric
Available in Single, Double, King and Super King. No flat sheet, no duvet cover: this is the layer that actually touches you.
We tell you to measure your mattress, so here are the numbers to measure against. Ten seconds now saves a return later.
Single — fits a 90 x 190cm mattress
Double — fits a 135 x 190cm mattress
King — fits a 150 x 200cm mattress
Super King — fits a 180 x 200cm mattress
Pocket depth: [CONTROLEER — vul echte cm in]cm. That covers a standard mattress with a topper on it. If yours is deeper, measure before you order.
Pillowcases: [CONTROLEER — vul echte cm in]cm, standard UK.
Machine wash at 30°C on a gentle cycle, on its own or with similar colours.
Tumble dry on low or line dry. Avoid high heat, it shortens the life of the elastic.
No bleach and no fabric softener. Softener coats the fibres, and a coated fibre moves less heat.
Sleep on it for ninety nights. Most cooling bedding gives you thirty, which means you buy in June and have to decide in July, before the nights that actually test it.
If you are not sleeping cooler and drier, and if the corners do not stay on, send it back for a full refund. The returns label is already in the box.
Free UK delivery on every order, with tracking.
Processing: dispatched within 24 hours on working days.
Returns: free within the UK, ninety nights, label included. You will not be posting anything to America.
You are probably one of them. The fabric is the same in all three cases, what changes is which part of the night it fixes.
If you've bought a cooling sheet before
Cool for ten minutes, then nothing. Sound familiar?
You get into bed and it feels lovely. Twenty minutes later it is the same temperature as you are, and by two in the morning you are turning the pillow over again. That is not a faulty sheet, that is what contact cooling does: it works once, then it is finished. Every fabric passes the first-second test, including the twenty pound ones. Ours measured Q-Max 0.42 at an accredited lab and the report is further down this page, but the number that matters to you is what happens at hour four.
Cool the second you get in
Still moving heat at hour four
Q-Max 0.42, measured not claimed
If one of you is hot and the other is cold
She's in a hoodie. You're on top of the duvet.
Most cooling bedding solves it for one of you and starts a different argument. Anything designed to chill makes the cold one colder, which is how couples end up with two duvets, or two rooms. This does not add cold. It moves heat away from whoever is producing it, so if your partner is not running hot, they will not feel anything happening at all. One sheet, two body temperatures, no negotiation at bedtime.
Moves heat, does not chill
The cold one stays comfortable
One bed again, not two duvets
If you wake up damp rather than hot
The 3am change of clothes nobody talks about
You keep a spare top on the chair. You shift over to the cool side of the bed. You have stopped thinking either of those is unusual. Heat is only half of it: the other half is the damp you are still lying in once the heat has passed. Cotton absorbs that moisture and holds it against your skin. This moves it into the weave and away from the surface, so what you wake up on is dry.

THE SPECIAL BENEFITS
Three things you will notice, and one you will only notice in the morning
Cool on contact, still cool at hour four, and corners that are still on the mattress when you get up.
Cool the second you touch it

Elastic all the way round, not just four corners
Every fabric has a number. Most brands don't print theirs.
Q-Max measures how fast a fabric pulls heat off your skin. Higher is cooler.

HONESTLY
This isn't for everyone
We would rather sell you nothing than sell you the wrong thing. Read the left column honestly before you read the right one.
Skip this if...
You already sleep through the night without getting too warm.
You want the room cooled, not you. That is a job for air con, not a sheet.
You expect it to feel like an ice pack. It moves your heat away, it does not chill you.
You are after a full bedding set with a flat sheet and duvet cover. This is the fitted sheet and pillowcases only.
You are shopping for the cheapest sheet on the shelf. This is not that.
You want a sheet that chills you. This moves your heat away, which is a different thing.
This is for you if...
Your bed feels cool for ten minutes and then it is over.
You wake between two and four most nights and cannot work out why.
Your fitted sheet comes off the same corner every single morning.
You have already bought a cooling sheet once and it did not do what it said.
Your back is damp but your arms are cold, and you have stopped using a duvet in summer.
One of you sleeps hot and the other sleeps cold, and the duvet is on the floor by morning.
You keep a spare top on the chair, and you have stopped thinking that is unusual.
Recognise yourself on the right? Then you have ninety nights to find out, on us.

Still cool at 3am, which is new
I've had two cooling sheets before and both felt lovely for about ten minutes. This one is still cool when I turn over in the middle of the night. That's the whole difference.

They tell you to measure your mattress before ordering. I did, ordered the right size first time, no returns. More brands should say that.

WHAT SLEEPING COOL COSTS
You already spent it. Just not on one thing.
Almost nobody buys one solution. Most people buy four over two summers, and none of them are still working the following June.
OptionWhat it costsThe catch
Portable air conditioner£300 to £600A hose out of the window, roughly the noise of a hairdryer, and it has to sit in the room with you. Plus electricity every night it runs.
A fan, then a second fan£20 to £150Barely costs a thing to run. It also barely works: it moves warm air around instead of taking heat away from your body.
A cheap cooling sheet£15 to £25Cool for the first minute, then it matches your temperature. Read the two-star reviews before you buy one.
Velrest™ Cooling Sheet Set£69.95Nothing to install, nothing to plug in, nothing to run. A number you can check, and ninety nights to decide whether it holds up on your bed.
Prices based on typical UK retail, 2026. A portable air conditioner also uses electricity every night it runs.

Buy in June. Decide in September.
Cool to the touch, hour after hour, still moving heat when you turn over at 3am, and corners that are still on the mattress in the morning. Most cooling bedding gives you thirty nights to check that, which means you decide before the nights that actually test it. Ours is ninety. Buy a bamboo or cotton set alongside it and sleep on both if you like. If theirs wins, send ours back for a full refund, even used, with the label already in the box.

WHO YOU'RE BUYING FROM
About us
It is 3am and you are still awake, and the bed is warmer than you are.
We started with that hour. Not with a product line, not with a colour range, just the question of why bedding that says cooling on the label stops working before midnight.
The answer turned out to be that the whole category measures the first second and nothing after it. So we had ours measured properly, put the report on the page, and gave you ninety nights instead of thirty to check whether the number means anything on your own mattress.
Yes, all of them do, including the twenty pound ones. Q-Max measures the instant your skin touches the fabric, and every decent fabric passes that test. The question is what it feels like at two in the morning, once your body and the sheet have met in the middle. That is a different property, and it is the one we tested for.
Ask any brand two things: what their Q-Max number is, and what happens at hour four. Most will answer the first and go quiet on the second. Ours is 0.42 and the report is on this page.
No, and this is the difference between cooling and regulating. A sheet that chills makes the cold one colder, which is why most cooling bedding solves it for one person and starts a different argument. This one does not add cold, it moves heat away from whoever is producing it. If your partner is not producing excess heat, they will not feel anything happening.
Related but not identical, and most bedding only addresses the heat half. Cotton absorbs moisture and holds it against your skin, so you carry on lying in it after the heat has passed. This fabric moves moisture into the weave and away from the surface, so what you wake up on is dry. We are talking about comfort and laundry here, not treating anything medical. If night sweats are new, persistent or worrying you, that is a conversation for your GP, not a bedding company.
That is the most common complaint in this whole category, and it is not bad luck: fabrics that move heat well are smooth, and smooth fabric slides. Most fitted sheets have elastic in the four corners only. Ours runs all the way round the edge, and the pockets are deep enough for a mattress with a topper on it.
The pockets are cut deep, which covers a standard mattress with a topper on it. Measure yours before you order anything, from us or anyone else. It takes ten seconds and saves a return.
No. It does not chill you, it moves your own heat away. If there is no heat to move, nothing happens. You will not end up colder than the room.
You have ninety nights, not thirty. Send it back for a full refund, free returns within the UK, and the label is already in the box.
