Best cooling pillows for hot weather and night sweats 2026

Hailed by many as being ‘the best pillow they’ve ever had’, the Simba Hybrid Pillow, whilst costly, is praised for its ability to keep you cool during the night while providing adequate support and cushioning for your neck and shoulders.

This versatile pillow comes full and firm (and is a snug fit in most standard-sized pillowcases). Offering complete flexibility to suit all sleepers, it’s filled with sustainable foam ‘nano cubes’ that can easily be removed to adjust the loft and firmness, making it softer or reducing the height to suit your preference.

The space-inspired ‘Stratos Active’ temperature regulation absorbs heat from your body and stores it, releasing it back to you if you cool down or the temperature drops during the night. The breathable cotton outer layer feels soft and smooth against skin with fibres to dissipate heat, while the open mesh border ensures maximum airflow, preventing overheating and keeping you cool and comfortable all night long.

Cooling pillows can be expensive, so if you’re looking for a more affordable choice, the Slumberdown Memory Cooling Pillow is a popular option retailing at under £20.

Best suited to side sleepers and with firm support and a memory foam wrap, the Slumberdown provides excellent comfort and support around your head and neck, ensuring good spine alignment and helping keep unwelcome aches and pains at bay.

The knitted ‘Cool Max’ cover is cooler to the touch than traditional foam, hypoallergenic and comfortable on the skin. It’s also moisture-wicking, ensuring your generated body heat doesn’t lead to sweat or discomfort, even on warmer nights after you’ve turned your pedestal fan off.

Due to the cover, this pillow is sponge clean only, so you may wish to purchase a pillow protector to keep it fresh and hygienic and expand its life span.

Another affordable option from a trusted brand, Silentnight have over 75 years of experience in creating sleep solutions suitable for all sleep positions, whether you’re a back sleeper, side sleeper or prefer to sleep on your stomach.

This innovative pillow is made from 65% microfibre and 35% gel, with a cooling pressure-activated gel pad that responds to your movements and prevents overheating during the night.

There’s no need to flip this pillow to find the cool side, the gel pad actively absorbs your generated body heat and provides a cool, calming sensation that can soothe you back to sleep.

If you’re prone to waking up with neck or back pain, you may need to opt for a firmer pillow to offer extra support and ensure good alignment during the night.

This CoolMax Contour Pillow has an extra supportive, slightly curved design, with three different heights that can be easily adjusted to suit your preferred sleeping position.

With Coolmax™ technology, the luxurious cover works to disperse heat away from your body, wick moisture and keep you cooler during the night. For those used to a very bouncy cushioned pillow, it may take a little while to adjust, but if you’re experiencing discomfort, a more supportive pillow can certainly enhance your overall sleep and wellbeing.

If you’re a front or side sleeper or tend to move around during the night, you may find firm pillows a little too restrictive and struggle to get comfortable as a result.

This medium support pillow from TheraPur comes with a choice of two sides - allowing you to choose between supportive memory foam that moulds to your movements or luxurious ‘down-like’ microfibre, even alternating between the two depending on your mood or sleeping position.

The hypoallergenic AntiCool cover absorbs your body heat, helping regulate your body temperature and prevent overheating or night sweats during the early hours. It’s a higher price point than some however, and as it’s spot clean only, we recommend getting a cover or protector.

Tried and tested by Mumsnet tester Katy: read her review of the Otty Deluxe Pure pillow.

This is one of those pillows that’s brilliant if you’re the right sort of sleeper – and maddening if you’re not. During testing, Katy (a hot sleeper who normally prefers a very flat pillow) found the Otty Deluxe Pure properly cooling, and that’s the headline. For anyone who overheats at night, it’s a rare memory foam pillow that doesn’t turn into a radiator by 3am.

The trade-off is the feel. This is structured and medium-firm, with basically zero “scrunchability”. Katy rated comfort and support as fine-but-not-life-changing, and said her sleep was “slightly worse” than with her usual flatter pillow – mostly because it’s firm and changes your position a bit. She did say it “moulded to my head nicely”, but it still won’t suit people who toss, turn, fold, punch or generally wrestle their pillow into submission.

So: if you’re a back sleeper (or a side sleeper who likes a firmer, shaped pillow) and you run hot, it’s well worth a look. If you want something adjustable, soft, or pancake-flat, you’ll probably end up annoyed – and wide awake.

With its bright yellow piping matched with a firm and supportive design, the Eve Sleep Memory Foam Pillow is a popular pick for side and back sleepers, offering significant support to keep your neck and spine in a comfortable position overnight.

Unlike some memory foam pillows which can feel a bit stuffy during summer, the Eve pillow features hundreds of tiny air holes, improving air circulation and allowing body heat to escape back into your surroundings. The removable cover is breathable and soft to the touch, with the option to remove it and pop it into the machine when it’s time for a clean or a refresh.

Whilst the Eve Memory Foam Pillow is not as soft or cushioned as plush pillows, it’s still soft and bouncy, regaining its shape easily to prevent those unsightly head hollows when you make your bed in the morning.

If you’re happy with your current pillows, but are looking for a cheap and simple way to prevent sweating or overheating at night, the Chillmax Pillow may be a handy solution to use on top of your pillow or inside of your pillowcase.

Filled with heat-activated gel, the Chillmax responds to your body temperature and absorbs the excess heat, drawing warmth away from your head and face. Whilst it won’t last the whole night, it can certainly help you drift off more comfortably, with cooling benefits lasting for up to three hours at a time.

Its small and portable nature makes it ideal for travel. During heatwaves and warm summer nights, you can pop it in the fridge for some instant cooling effects, whether that’s to sit on, lie on or place across your lap.

Tested by Mumsnet user, Christine: Read our full Coolflex Cool Gel Memory Foam Pillow review

If overheating is your biggest sleep disruptor, this is where the Coolflex impressed most. We tested it with Christine, a self-confessed hot sleeper, and she genuinely noticed the difference. She said she could “feel the coolness” when lifting her head and that it stayed cool around her neck during the night. Crucially, she didn’t feel it trapped heat -something that often lets memory foam down.

It’s a firm, structured pillow that holds its shape extremely well. As a side sleeper who moves around, Christine liked that it didn’t flatten, go lumpy or need constant plumping. The build quality feels solid too, with good stitching and materials, and it looks neat and supportive on the bed.

The catch is comfort. Christine usually prefers a medium feel and found this one too firm over a full night, eventually noticing some neck ache. It’s not adjustable either, so there’s no way to tweak the height or softness - what you buy is what you sleep on.

At £39 on sale, it’s far cheaper than premium cooling memory foam options like Tempur, and for the right sleeper it could be a great buy. If you like a firm, supportive pillow that stays put and runs cool, it delivers. If you prefer more give, it may feel too unyielding.

Tested by retiree, Christine: Read our full Tempur Prima SmartCool Pillow review

Tested by Christine, a retiree and predominantly side sleeper who favours a medium-firm pillow, the Tempur Prima SmartCool Pillow delivered the level of structured support she looks for. “I liked how firm it was, medium, and how my head just sank into it,” she says.

That balance of structure with a little sink is often the sweet spot for side sleepers looking for the ideal pillow. Christine moves position frequently, (6+ times a night), yet still reported that it “significantly reduced discomfort”, scoring both head and neck support an impressive 8 out of 10. Crucially, she “slept on it comfortably straight away”, with no awkward breaking-in period or midnight second-guessing.

Compared to her usual rebound pillows (which she says “never last very long”), the Tempur Prima felt thicker, more substantial and noticeably more comfortable. It didn’t dramatically transform her overall sleep - she reported “no difference” in sleep quality compared to her usual pillow, but in terms of pressure relief and comfort, it was a clear step up.

As for the SmartCool™ technology, Christine, a self-confessed hot sleeper, found the temperature performance steady rather than dramatic. She didn’t report a noticeable cooling boost but equally didn’t experience heat build-up or discomfort. In her words, there was “no difference” in how hot she felt overnight. For those looking for a pillow that maintains a consistent, comfortable temperature rather than delivering an obvious cooling sensation, that may well be enough. The cover does, in fact, feel slightly cool to the touch.

Where it falls slightly short is shape retention. Christine found she had to “reshape the pillow every morning as the filling had moved to the outer edges” and admitted to “constantly adjusting it”.

Build quality, however, is reassuring. She rated the stitching as “excellent”, found the materials good, and appreciated the removable, washable cover for easy care. No chemical smell, no fuss - just open and use.

Tried and loved by Mumsnet Senior Content Editor, Rebecca: read her review of the Ava Innes pillow.

If you want a cooling pillow but you’re not that fussed about “space-age gel technology”, this is a very grown-up alternative. It’s wool-filled (so naturally breathable), and during review Rebecca found it didn’t feel clammy or heat-trappy - more “comfortable and fresh” than “ice pack for your face”.

The big selling point is the adjustability. You can add or remove wool filling depending on whether you like your pillow lofty and supportive or a bit lower and squishier, which is handy if you’re a side/back combo sleeper, or you’re just bored of trying to make one pillow do every job.

A couple of real-world warnings: there’s a definite wool smell when you first open it (it fades, but it’s a Moment), and it’s not cheap. Rebecca also flagged that it will settle over time, so you may need to top it up, rather than expecting it to stay forever-plump with zero effort.
