Best cooling mattress topper for a great night's sleep
Too hot to sleep but not ready to splurge on a whole new mattress? We’ve found the best cooling mattress toppers to help you stay cool and comfy, recommended by Mumsnet users.
By Zoe Griffin | Last updated Dec 30, 2025
If you find yourself throwing the duvet off at 3am or flipping your pillow to the “cold side” night after night, you might be due a cooling mattress topper. Designed to regulate body temperature and reduce overheating, these clever add-ons can transform your bed without the cost (or hassle) of replacing your mattress. Whether you’re dealing with a heatwave, a warm upstairs bedroom, or the delights of night sweats and perimenopause, the best cooling mattress toppers wick away heat and stop you from overheating.
Cooling mattress toppers are typically made with temperature-regulating materials like ventilated memory foam, wool, or other cooling fabrics that absorb and disperse heat. Some use open-cell construction for better airflow, while others feature moisture-wicking covers to keep you feeling fresh. While they don’t actively chill the bed like cooling pads, a good topper can still drop the temperature by a few degrees, which is enough to make a real difference to your sleep.
While investing in a cooling mattress is always an option, a cooling mattress topper is a wallet-friendly way to upgrade your sleep. Whether you’re searching for the best cooling mattress topper for night sweats, a super comfortable memory foam cooling mattress topper for a feeling of luxury, or just a budget-friendly option to keep your bed more breathable in summer, we’ve rounded up the most recommended picks from real Mumsnet users. If you're not sure whether a topper is right for you, check out our guide to the best mattress toppers to compare all types.

Tested by Mumsnet editor Poppy O'Neill: Read our full Panda London Mattress Topper review
The Panda topper gets loads of love on the Mumsnet forums. It’s made from breathable bamboo, which is naturally cooling and soft, with a layer of cooling gel Hydro Foam that helps relieve pressure while keeping things chill.
It stays in place thanks to handy straps, and the removable bamboo cover is machine washable, which is useful in case there are kid-related accidents (or sticky fingers) in bed.
At less than £100 for a double, it’s gentle on the wallet while still being effective at cooling hot sleepers. Added to that it has an impressive 10-year guarantee, effectively bringing the cost down to just £10 per year for a double.

If your budget’s tight but you still want a cooler, comfier night’s sleep, the BedStory topper is well worth a look. One Mumsnet user said it helped improve their sleep quality while they saved up for a new bed and sometimes that’s exactly what you need.
It’s filled with breathable microfibre that offers a soft, cloud-like feel without adding heat. The quilted stitching keeps the padding evenly spread, so you won’t get that annoying lumpy feel. It’s also light and easy to pop on and off the bed, and while it might not last you years, it’s a popular short-term fix.

What Mumsnet users say
Waking up drenched in sweat is no fun and if you’re dealing with hormonal changes or hot flushes, a temperature-regulating topper can be life-changing. The Floks wool topper is one of the most luxurious options on the list, and Mumsnetters say it’s totally worth the splurge. Made from natural, breathable materials, it cleverly regulates temperature - keeping you cool in summer, cosy in winter, and dry no matter the season. It’s naturally hypoallergenic and resistant to dust mites and mildew, so it’s a great choice for anyone with allergies or asthma.
Another bonus is that the Floks mattress topper is a more environmentally conscious choice than synthetic alternatives. It’s made using natural wool, a renewable and biodegradable material that breaks down harmlessly at the end of its life. Unlike memory foam, which is petroleum-based and difficult to recycle, wool is a sustainable resource that requires less energy to produce and has a much lower environmental impact.

What Mumsnet users say
This budget-friendly M&S cooling mattress topper is filled with polyester fibres that are designed to be breathable and paired with a 100% cotton cover that helps wick away moisture. It’s not going to give you the deep hug of memory foam, but if you prefer a more airy, cloud-like feel, this one’s great if you’re prone to getting too warm.
To reduce the temperature even more, you could also pair it with other M&S Comfortably Cool bedding items such as a cooling sheet or a cooling duvet, which also comes highly rated by Mumsnetters and featured in our Best cooling blankets guide.
A downside is that you can only wipe it clean as the care instructions recommend against both machine washing and tumble drying. We’d recommend investing in a decent waterproof mattress protector in case of accidents.

Memory foam gets a bad rap for trapping heat, but the Dormeo Octasmart seems to be the exception. It’s made with “Octasprings” – little foam springs with open sides to let air flow freely – and this clever structure helps stop that suffocating, sweaty feeling.
It also moulds to your body for pressure relief, making it ideal if you sleep on your side or have an older mattress that’s lost its bounce. It’s definitely on the firmer end of the comfort scale, which suits some better than others, but if you like supportive over sinking into the sides then it could be perfect. Multiple Mumsnetters said they “love” it. Just note that you can only spot wash it or wipe it clean so it wouldn’t suit children’s beds.

What Mumsnet users say
This budget-friendly wool topper from IKEA has been picked out as being helpful by Mumsnetters who struggle with overheating. It’s not thick or squishy like some of the other options, but that’s what makes it work so well in warm weather. The thin wool layer adds just enough softness while helping to regulate temperature and wick away moisture.
One user who had a memory foam mattress said this topper helped cool it down – and for £50, that’s impressive. The cotton outer is soft and breathable, and because it’s machine washable, it’s easy to keep fresh even through the hottest months. Being machine washable also means it should last longer, working out at great value per sleep.

Priced at over £210 for a double, the Devon Duvets wool topper isn’t cheap, but it should last. Handcrafted in Devon with meticulous care, each topper is individually made to order by a team of experienced seamstresses, bringing a level of craftsmanship and attention to detail you won’t find in mass-produced alternatives.
What really sets this topper apart is the quality and provenance of the wool. It’s fully traceable from farm to topper, sourced from a trusted group of British farmers who Devon Duvets has worked with for over 12 years. These farms uphold the highest standards of animal welfare, and the wool itself is certified by the British Wool organisation so you know exactly what you’re sleeping on. With over 1.2kg of wool per square metre, this topper offers a plush, breathable layer of support that’s designed to be both cushioning and temperature-regulating.

How do cooling mattress toppers work?
Cooling mattress toppers are designed to wick away heat and moisture from your body while you sleep. Some use open-cell memory foam or gel-infused foam to disperse heat, while others - like the best cooling gel mattress topper - contain cool-to-the-touch layers or airflow channels. Natural materials like wool or bamboo are also great at thermoregulating. While they won’t actively cool like electric mattress pads, a good topper can drop your sleep surface temp by several degrees.
What’s the best cooling mattress topper to buy?
If you want the best cooling mattress topper overall, the Panda Mattress Topper ticks all the boxes. Mums rave about how it transforms even the most tired mattress, with a layer of breathable bamboo that helps wick away moisture, plus supportive Hydro Foam™ that moulds to your shape without trapping heat. It’s soft, cool, sustainably made, and has a washable cover - ideal for family life.
But if you're after the best budget cooling mattress topper, the BedStory double topper is a brilliant affordable option. While it’s not packed with techy features, it offers great breathability, a soft finish, and enough padding to refresh a mattress that’s seen better days.
