Key takeaways
- The cheapest fix is a lightweight 4.5 tog summer duvet, usually under £25.
- Cool-touch and bamboo bedding move heat away from your skin. They do not refrigerate the bed, so the effect is real but gentle.
- Gel pads and cool-touch fabrics warm up after you have lain on them a while, so they work best alongside a fan or an open window.
- Bamboo and other viscose sheets tend to feel cooler than cotton because they wick sweat faster.
Britain has just been through one of its hottest spells on record, with 37.3°C logged at Santon Downham on 27 June and air conditioning units selling out across the country. When the bedroom will not cool down, the bed itself is the next place to look. Cooling bedding will not turn a stuffy room into a fridge, but the right duvet, topper, pillow and sheets can take the edge off a sweaty night for a lot less than an AC unit. Here is what is worth buying, and what each option will and will not do.
If the room itself is the problem, start with our guides to cooling a bedroom in a heatwave and how hot is too hot to sleep, then come back to sort the bed.
How we picked these
We looked for bedding that is sold in the UK, in stock on Amazon, and that targets heat rather than just claiming to be “luxury”. We weighted four things: how the material handles heat and sweat (bamboo viscose and cool-touch finishes score well), real customer ratings, price against what you actually get, and ease of washing, since summer bedding gets washed a lot. The Sleep Charity puts the ideal bedroom temperature at about 16 to 18°C, so the aim of everything below is to nudge you closer to that range, not to fight a 30°C room on its own.

The best cooling bedding to buy now
Slumberdown Cool Summer Nights 4.5 Tog Duvet
Best for the cheapest first fixA 4.5 tog duvet is the single easiest swap if you are still sleeping under a 10.5 tog all year. It is light and breathable, washes at 40°C and comes in single up to king, so it is the obvious place to start before you spend more.
The catch: 4.5 tog can feel too thin once autumn arrives, so you will want a warmer duvet to switch back to.
4.5 tog, machine washable, UK made · around £20
Check price on Amazon →Zinus Cooling Bamboo Mattress Topper
Best value topperA 5cm bamboo-cover topper that adds a cooler, softer layer on top of a hot mattress without the price of memory foam. Elastic corner straps keep it in place and the cover comes off for washing.
The catch: It is thin compared with a foam topper, so it smooths a firm mattress rather than transforming it.
5cm, bamboo cover, elastic straps · around £37
Check price on Amazon →Panda Gel Infused Memory Foam Bamboo Topper
Best for support plus coolingGel-infused memory foam under a bamboo cover, so you get proper pressure relief for your back and hips while the gel and bamboo help shift heat. The pick if a thin topper has not been enough and you want one upgrade that lasts.
The catch: Memory foam still traps some heat, and at around £140 it costs more than a budget mattress.
Gel memory foam, bamboo cover, straps · around £140
Check price on Amazon →BETU Cooling Shredded Memory Foam Pillow
Best for hot sleepers who keep flipping the pillowShredded memory foam you can add or remove to set the height, with a cool-touch cover so you are not chasing the cold side all night. Good for back and side sleepers who run warm.
The catch: The cool-touch cover warms up under your head after a while, so it is comfort rather than air conditioning.
Adjustable fill, cool-touch cover, king size · around £25
Check price on Amazon →Linenwalas Bamboo Sheet Set
Best for cooler sheetsBamboo viscose sheets wick sweat faster than cotton and feel cool and smooth against the skin, which is exactly what you want on a sticky night. This set includes a deep-pocket fitted sheet and two pillowcases.
The catch: Bamboo viscose needs a gentle cool wash and can crease, so it asks for a bit more care than poly-cotton.
100% bamboo viscose, deep elastic pocket · around £50
Check price on Amazon →Accurate Reusable Cooling Gel Pads
Best for an instant cold spotA pair of reusable gel pads you lay on the bed for a quick cold patch, handy for your back or behind your knees as you drop off. The cheapest way to try cooling bedding, and you can pop them in the fridge first.
The catch: The cold lasts maybe 20 to 30 minutes before body heat catches up, so this is a short-term hit, not all-night cooling.
2 pads, reusable, fridge friendly · around £13

Does cooling bedding actually work?
Yes, within limits. Bamboo and cool-touch fabrics move heat and sweat away from your skin so you feel less clammy, and a lighter duvet means less heat is trapped. None of it refrigerates the bed, so on a very hot night you will still want airflow from a fan or open window.
What tog duvet is best for summer in the UK?
A 4.5 tog duvet is the usual summer choice. If you really feel the heat, some people drop to a 1 tog or just a sheet during a heatwave, then move back up to 9 or 10.5 tog for the colder months.
Are bamboo sheets really cooler than cotton?
Most people find them cooler. Bamboo viscose is very good at wicking moisture, so sweat moves off your skin quicker and the sheet feels less damp. Cotton breathes well too, but it tends to hold sweat for longer.
What is the fastest way to cool the bed in a heatwave?
Strip back to a thin sheet or 4.5 tog duvet, put a cool-touch or bamboo layer next to your skin, and aim a fan across the bed. A chilled gel pad gives you a quick cold spot while you fall asleep. For the room itself, see our best tower fans guide.
