Menopause affects more of the night than the heat
Menopause can disturb your sleep through more than temperature changes, so a cooler bed addresses only part of your comfort. The NHS describes hot flushes as your face, neck and chest suddenly feeling very hot or cold.2 You may sweat a lot, have palpitations or anxiety, or feel dizzy. They can last several minutes and happen during the day or night. The NHS calls them night sweats when they happen at night.
The NHS says sleep problems may be worse if you also have night sweats. The Gombert-Labedens 2025 narrative review describes nocturnal hot flushes as a significant source of sleep disruption.1 Separately, the NHS insomnia guidance lists menopause among conditions that can cause insomnia.5 It also lists rooms that are too hot or cold and uncomfortable beds among common causes.
Women's Health Concern explains that hormone changes narrow the temperature range tolerated by the brain's temperature control. Small changes in your temperature or the room can then set off a flush. That helps explain why the same bedroom can feel different from one night to the next.
According to the NHS, symptoms can happen during perimenopause, menopause and afterwards. They usually last seven to nine years, sometimes longer, and can change over time. Muscle aches and joint pains are among those symptoms, too. When you're considering a mattress, pay attention to pressure at your hips and shoulders as well as warmth. Both affect how comfortable you feel in bed.
Hot flushes at night: the room and your layers come first
Make the room comfortably cool and your clothing easy to remove before spending on a different mattress. The NHS suggests lightweight clothing and a cool bedroom, with a cool shower, a fan or a cold drink as things you can try. A fan within reach saves you getting out of bed to switch it on. This is one occasion when arranging everything within arm's reach counts as excellent planning.
For room temperature, around 18C suits my idea of a comfortable bedroom. In a lab study of post-menopausal women cited in the Gombert-Labedens review, lowering bedroom temperature to 18C reduced hot flushes in the first half of the night but not the second. The review says patterns across studies are not clear.
Cool should still feel comfortable. In cold weather, NHS winter health guidance says to heat rooms you regularly use, including your bedroom, to at least 18C if you can, particularly if you have a health condition.6 There's no need to audition for a polar expedition. Use enough heating to stay comfortable, then adjust your bed covers.
Women's Health Concern suggests light clothing layers that are easy to remove during a hot flush, plus loose clothes in natural, light fabrics such as cotton. The coordinated pyjama set can have a night off if it's too warm. Choose clothes you can loosen or take off easily, without tight cuffs or several awkward fastenings.
For bedding, Women's Health Concern suggests cotton sheets with a lower thread count and removing heavy, thick down duvets. It also suggests a towel in bed to absorb sweat before the sheets become drenched. When comparing sheets, look at the fabric and weave instead of assuming the highest thread count will suit a warm night.
Separate duvets let a partner who runs cold use more insulation while you keep lighter covers and a cool room. I love a heavy tog because the weight helps me settle, so I understand the duvet war from the well-insulated side. Compare duvets for each sleeper's comfort, with covers you can pull back easily when you feel hot.
The NHS also suggests avoiding or reducing potential triggers, including spicy food, caffeine, hot drinks, smoking and alcohol. Notice whether any of these coincide with your flushes, especially in the evening. Alcohol absolutely ruins my sleep, with my mind racing through repeated wake-ups. A nightcap is a poor bargain for me. Change an evening habit that seems to affect your nights before spending money on another bed accessory.
If the mattress needs replacing, choose one that doesn't hold heat against you
A mattress that feels less heat-holding, with some give beneath your hips and shoulders, is the sensible comfort choice when yours needs replacing. I favour pocket springs with natural fillings for this job. Wool and cotton fillings feel cooler to sleep on and wear well, and the springs provide support beneath them. Look through mattresses with natural fillings if you prefer a less enveloping surface.
Memory foam gives lovely cushioning around pressure points, but deep memory foam runs warm whatever the cooling claim says. It also lets you sink further into the bed, which some people love and others find restrictive when turning. For a broader comparison of heat-holding constructions, use our hot-sleeper mattress guide.
To my mind, latex is the best material most people overlook. It feels cool and bouncy, with cushioning that springs back when you move. The price is the awkward part, especially when you were hoping to have money left for something more exciting than bedtime. Compare how much latex is in the mattress and what supports it underneath.
If you love foam's cushioning, gel foam gets a more favourable look from me. I think it makes a worthwhile difference to the feel, though a deep foam mattress can still feel warm. I'm less convinced by cooling covers and phase-change fabrics. A cool touch when you first lie down matters less to me than whether you're comfortable later in the night.
For aching hips and shoulders, the NHS insomnia guidance advises making sure your mattress, pillows and covers are comfortable. Let your shoulder and hip settle into the surface without your middle sinking too far. The aim is a comfortable lying position with enough room to turn easily.
Build matters before sleeping position when I narrow down firmness. A heavier sleeper generally needs firmer support, while a lighter sleeper needs more give. Side sleeping usually calls for a softer surface than back sleeping. These are shopping judgements I use to narrow the options.
| Your build or sleeping position | What to look for in the feel |
|---|
| Lighter build | A softer surface that gives beneath you without needing much weight. |
| Heavier build | Firmer support beneath the cushioning, so your middle stays supported. |
| Mostly side sleeping | Extra give around your shoulder and hip. |
| Mostly back sleeping | Enough support beneath your hips, with comfortable cushioning on top. |
| Frequent position changes | A responsive surface that lets you turn without a deep sinking feeling. |
The firmness words beside a mattress help you narrow the selection, but check the construction and the feel you prefer as well. Read the return conditions before ordering, because a few minutes lying on a bed won't settle how you'll feel through a whole night. Download the terms and check any collection charges and conditions for getting your money back.
A topper can soften a too-firm mattress, but it won't fix a dip
A topper is useful when the mattress underneath is sound and you need a softer surface. It follows the shape beneath it, so a dipped mattress still leaves you lying in a dip. A thick memory-foam topper also adds a substantial layer of heat-holding foam. Check the mattress and its base before covering either with another layer.
For a warmer sleeper, a thinner latex or wool topper gets my vote over thick memory foam. Buying the deepest one available is an understandable enthusiasm, but depth alone isn't the goal. Compare mattress toppers for the amount of cushioning you need and the material you'll be lying on. For sweat-soaked sheets and questions about protectors, our night-sweats guide covers those bedding decisions.
What to avoid
Avoid adding insulation or buying equipment in the hope of treating hot flushes. I think the wellness market is far too good at selling to tired people. The least glamorous changes are often the cheapest ones to try, so check what's already on the bed and what happens in your evening before ordering anything.
- One heavy, thick duvet that's difficult to shed. Use lighter covers you can pull back and replace easily. Women's Health Concern specifically suggests removing heavy, thick down duvets.
- Evening triggers you've noticed affect you. The NHS suggests reducing or avoiding potential triggers such as spicy food, caffeine, hot drinks, smoking and alcohol.
- Heating the whole bedroom to suit the colder sleeper. Adjust insulation individually instead of raising the room temperature for both of you. In winter, follow the NHS advice to keep regularly used rooms at least 18C if you can.
- Deep memory foam or a thick foam topper when warmth wakes you. More cushioning can also mean more heat-holding material around you. Choose the amount of give you need without automatically choosing the deepest layer.
- Buying a cooling gadget or mattress as if it treats hot flushes, instead of talking to your GP about your options. A shopping basket is wonderfully easy to fill, but a mattress purchase belongs with your comfort decisions.
When to contact your GP
NHS guidance on menopause and perimenopause symptoms says to contact your GP if you think you have symptoms of menopause or perimenopause and want to know what your options are; you have symptoms like a fast heartbeat (palpitations); you still have periods but your bleeding pattern has changed and you're bleeding more, not less, than before; or you have not had a period for 12 months or more, and you have any vaginal bleeding. Early advice can help reduce the effects of menopause and perimenopause on your health, relationships and work.
The NHS also says to see a GP if you have postmenopausal bleeding, even if it's only happened once; there's only a small amount of blood, spotting, or pink or brown discharge; you do not have any other symptoms; or you're not sure if it's blood. Postmenopausal bleeding is not usually serious but can be a sign of cancer. Cancer may be easier to treat if it's found early.
Wool-filled mattresses on this list, and what else is inside them
The mattresses below are WantMattress's own picks, chosen from published specifications and retailer information.
Wool in a mattress name is only part of the filling list. These three examples show the differences to look for alongside it, from foam cushioning to cattle hair. Check the exact model's layers and whether the retailer takes a mattress back once you've slept on it.
British wool and foam cushioning over pocket springs make the Solace an option for someone who wants both materials. Dreams lists a natural viscose-cotton blend cover, followed by British wool, Platinum 3D foam, micro pocket springs and the main individually wrapped pocket springs. The layers are mirrored on the other side, with hand tufting on both faces. This is not an all-natural or foam-free build. I like having the layers spelt out, because choosing wool needn't mean excluding foam, provided you're happy with that combination.
Dreams grades the Solace medium firm and asks you to turn it regularly and rotate it head to toe. Clean-sheet day has acquired another job. Check whether that feel and both care tasks suit you before ordering. The cotton is in the cover, not the fillings, and Dreams doesn't identify the foam as memory foam. Anyone avoiding synthetic foam should examine the Blackwell, which Woolroom explicitly describes as free from it. Compare its full filling list with the materials you're willing to buy.
For someone who likes fibre cushioning and sits on the side of the bed, the Wool Luxe's reinforced border appeals to me. MattressOnline lists pocket springs including mini pocket springs, British wool blended with cashmere, and high-density polycotton layers. Sleepeezee describes a tufted damask cover and a calibre edge, which the retailer explains uses thicker-gauge outer springs to support the border. MattressOnline also describes side air vents. The combination of fibre comfort layers and extra support around the edge is what draws me to this build.
Both MattressOnline and Sleepeezee grade it medium, so check whether that feel suits your build. Neither lists foam, latex or gel, but Sleepeezee includes a high-density support layer without identifying its material. Ask what that layer contains if you're excluding foam. The mattress is double-sided, with turning handles and instructions to flip it every few months. Someone who needs a mattress that stays the same way up should look elsewhere. Before buying, check that you can safely flip it and keep up that routine.
White cattle hair is the distinctive filling in the Blackwell, alongside traceable British wool and cotton. Woolroom describes it as adding structure and lift, and lists hand-nested calico pocket springs with merino-rich ticking. The finish includes hand tufting and hand side-stitching at the edge. Woolroom states that the mattress is free from synthetic foams, glues and chemical fire retardants. This build appeals to me for someone who wants natural fillings instead of synthetic foam and is comfortable buying animal fibres beyond wool.
The Blackwell comes in Soft, Regular and Firm tensions. Pick the tension for your build, and read Woolroom's return terms before choosing. Anyone avoiding cattle hair should leave this mattress out, even if the wool and cotton are appealing. It is also double-sided, and Woolroom asks for regular turning during the early months, then every three months. A mattress that doesn't need flipping is a better fit when that care is impractical. Check that you can manage the turning safely before placing an order.
