The 8 best mattress toppers - tested for comfier, more supportive sleep

If your sleep hasn’t been quite what it used to be, thanks to night sweats, aches and pains, or that restless feeling of tossing and turning, you’re not alone. As our bodies change, so do our sleep needs, and sometimes even the best mattress can start to feel a little less supportive than it once did. That’s where a good mattress topper comes in, offering an instant comfort boost without the expense of replacing your whole bed.

In an ideal sleep setup, you’d have the best mattress for your body, topped with a supportive mattress topper, dressed in the best sheets to keep things fresh. But life happens, hormonal changes, injuries, or simply the passing of time can throw things off, and that’s when a mattress topper can be a total sleep saviour. These clever layers can add extra cushioning, support, or even cooling technology to bring comfort back to your nights.

I’ve tested some of the best mattress toppers on the market, from trusted brands like Simba, Woolroom, Eight Sleep, and Dreams, to find out which ones really help when your sleep needs shift. Whether you’re going through menopause, trying to soften a too-firm bed, or simply looking to breathe new life into your existing setup, these are my expert-approved favourites for every sleep style and season of life.

The best mattress toppers, for every kind of sleeper

Image 1 of 9

Quick summary: For reliable comfort and support across all sleep styles, with subtle cooling that feels fair for the price.

It’s highly likely you’ve already come across Simba, one of the disruptive sleep brands that emerged alongside Emma and Nectar Sleep over the past decade. Given the brand’s reputation for some of the best mattresses and pillows in the category, I expected its topper to follow suit.

After speaking with the brand’s experts, I tested the Hybrid Mattress Topper, their most popular option, designed to suit all sleep styles with layered support that keeps back and side sleepers aligned through the night.

Over several months of testing, it lived up to those comfort and support promises: I rotate between front, side, and back sleeping, and each position felt natural on the Simba Hybrid. The cooling features were noticeably subtler than the active water-cooling in the Eight Sleep Pod, but considering this topper costs around 5% of the price, it’s a very reasonable compromise for most sleepers.

Most affordable mattress topper

Image 1 of 9

Quick summary: Great value and reliably breathable, this delivers cool, cotton comfort without the premium price tag.

This isn't just any old mattress topper. This is an M&S mattress topper and for me it strikes the ideal balance between price and performance. While plenty of specialist sleep brands compete for the best budget spot, the roughly £70 price tag here hits a real sweet spot.

Having tested toppers ranging from £30 to £3,000, I’ve found that going much cheaper usually means sacrificing breathable materials for synthetics like polyester, which can trap heat and irritate skin. After sleeping on the M&S Comfortably Cool Mattress Topper, I found it lived up to its name: the cotton cover felt soft and breathable, keeping me comfortable overnight.

It’s like adding a light duvet layer than a structured support system, so it won’t dramatically change a mattress, but it does take the edge off firmer beds. While it doesn’t actively cool (and won’t cure night sweats), it feels noticeably fresher than memory foam and cheaper toppers I’ve tested. If you want a simple, breathable layer with good eco-credentials, including UK manufacturing, this is an affordable option that performs well, even if some pricier toppers offer more advanced support.

Best cooling mattress topper

Image 1 of 7

Quick Summary: Luxurious, breathable, and beautifully natural, this is a dream buy for hot sleepers who want chemical-free comfort.

This is easily one of the most luxurious natural mattress toppers I’ve ever tested, both in how it feels to sleep on and in the craftsmanship behind it. The wool filling, sourced entirely from the Chatsworth Estate in England, is naturally breathable, making it an excellent option for hot sleepers, and you can even trace the sustainable production process. Once collected, the wool is wrapped in an unbleached organic cotton cover, which gives the topper a soft off-stone colour rather than a bright white finish (something I actually liked).

It’s also certified by the Allergy UK Seal of Approval, meaning it’s been tested for dust mites, allergens, bacteria, and fungus, ideal if you have sensitive skin or want to avoid adhesives and chemicals. Sleeping on the topper feels like lying on a very thick duvet: beautifully cushioning and cosy, though not the most structured, so it works best paired with a firmer mattress to maintain spinal alignment. You’ll also want to re-plump it regularly to keep the loft. I currently have this topper on my own bed, which says plenty.

You can find out more in Emily's full Woolroom Washable Mattress Topper review. I also have this on my bed at the moment, which speaks for itself, I think.

Best mattress topper for back pain

Image 1 of 7

Quick Summary: Cushioning, pressure-relieving, and surprisingly fresh, this is a brilliant choice for easing everyday aches without overheating.

No mattress topper can claim to cure back pain, that’s a job for a specialist, but if your mattress leaves you with sore joints or pressure points, memory foam can make a big difference. The Panda Memory Foam Mattress Topper stood out during testing for exactly that reason.

As a keen runner, my knees, hips, and spine often feel the strain, but the sink-in softness here was instantly soothing and delivered some of the best sleep I’ve had in years. Unlike many memory foam toppers, which can feel overly warm and clingy, this one stayed relatively fresh overnight. I wouldn’t call it actively “cooling”, but I never woke up hot and paired with bamboo sheets it actually felt chilly enough that I swapped them out in September.

Sustainability is another highlight: the topper comes with a removable, washable bamboo cover and the foam itself is bamboo-infused, helping reduce reliance on harsher chemicals. Even the elastic corner straps are thoughtfully made and do a great job of keeping the topper secure without distorting its shape. Thicker memory foam toppers exist, including options from brands like Tempur sold at Dreams, so if your mattress is extremely firm you might want more depth, but for most sleepers this eco-minded, pressure-relieving layer is a fantastic upgrade.

Best cooling mattress topper

Image 1 of 4

Quick Summary: High-tech and seriously effective, this actively cools (or warms) your bed to optimise sleep, but it comes with a luxury price tag.

When researching cooling mattress toppers for hot sleepers, particularly those dealing with menopause, I found plenty of breathable options, but nothing quite like the Eight Sleep Pod 3 from Eight Sleep. It’s in a completely different league. The system tracks key biometrics including heart rate, body temperature, and VO2 max, then automatically adjusts the temperature of water circulating through the topper to keep you at an optimal sleep temperature.

You can control the settings manually, but I eventually let the system take over, and it would subtly intervene overnight, cooling the bed to help keep me in deeper sleep stages. Beyond temperature control, it can gently wake you using vibration or warmth instead of a harsh alarm and generally nudges you towards healthier sleep habits. In testing, it improved my sleep more than anything else in this guide, to the point that it’s spoiled other beds, even in luxury hotels.

The downside, of course, is the price: it costs ten or even twenty times more than most toppers here, and full access to the features requires a subscription. Still, despite the steep investment, it’s easily the best mattress topper I’ve ever slept on.

Best mattress topper for side sleepers

Image 1 of 4

Quick Summary: Plush, pressure-relieving, and quietly temperature-stable, this is a great pick for side sleepers who want memory foam without the usual heat build-up.

The TheraPur ActiGel Cool Mattress Topper from TheraPur ticks plenty of appealing boxes: gel, cooling, and therapeutic comfort. In practice, that translates to a thick, gel-infused memory foam topper designed to cushion pressure points, particularly for side sleepers.

Since I can usually control the position I sleep in, I committed to side sleeping throughout testing. Normally, that would leave me with hip, shoulder, and back pain (especially on my firm mattress and with all the running I do), but the deep, soft foam here created a supportive cushion that kept me comfortable all night.

Memory foam can often feel overly warm, but this topper stayed fairly temperature neutral: I didn’t wake up sweaty, yet I wasn’t actively cooled either, my body temperature simply stayed stable, which is impressive for memory foam, even if it can’t compete with the active cooling of the Eight Sleep Pod 3. It was also easy to fit, didn’t require time to expand like some toppers, and stayed securely in place with minimal motion transfer overnight. If it had stronger sustainability credentials it would rank higher, but even so, it’s still a solid contender in the guide.

Best natural mattress topper

You can see the Floks reaches all four corners of the bed perfectly

This is the texture of the Floks Topper. It's really soft and comfortable to lie on.

The elastic straps on the bottom of the topper hold it firmly in place

This looks slim on the bed, but it feels like a full, luxurious layer added on top of the mattress

Quick Summary: luxurious, naturally temperature-regulating, and beautifully plush, this is an investment in your sleep. It's worth it if you want to avoid the chemicals and stay cool.

You spend one third of your life asleep and I've always lived (and slept) by the principle that you should keep chemicals as far away from you as possible. That's why the Floks Wool Mattress Topper is one of my favourites from a cooling, comfort, and eco-conscious perspective.

Crafted from traceable British wool and unbleached Egyptian cotton, the Floks Mattress Topper certainly ticks a lot of boxes for sustainability. The B Corp brand has managed to create an ultra-natural mattress that smells a little 'earthy' at first, but that enhances its credibility. I have been sleeping on this for months and it's brilliant.

To add to the Floks many, many impressive credentials, the combination of wool and cotton is really effective at naturally keeping you cool at night. I am a hot sleeper and I found myself getting longer, deeper nights of sleep when I put this on my bed. I even had someone going through menopausal night sweats test it out and she gave it a thumbs up saying "my skin felt fresher and clearer when I woke up. I didn't think a topper could make that much difference for me."

Best hypoallergenic mattress topper

Image 1 of 6

Here's what the Hypoallergenic Comfort Topper looks like rolled up on a bed. It's surprisingly compact.

The elastic straps that hold The White Company's Hypoallergenic Topper are easy to slide around the mattress and they keep it in place too.

You can see that this is a good fit on the bed, even when it's fresh out of the packaging.

This is the delicate texture of The White Company's Topper.

You can see it offers 6cm of sink-in softness.

Here's another angle of the topper's texture. It looks good enough to sleep on.

Quick Summary: If you have sensitive skin and you a topper that's gentle, low maintenance, and super soft. It's not natural, but ticks a lot of boxes.

If I told you that The White Company's Mattress Topper is one of the most comfortable models on the market, you won't be surprised. You also wouldn't be surprised to know that it's one of the best quality toppers too. What you might find surprising is that it's also affordable too.

With fistfuls of sleep credentials, this had to have a place in our buying guide. It's 6cm deep, adding a gorgeous layer of plushness to your bed. It's soft and comfortable to sink into, perfect if you've ended up sleeping on a mattress that's a little too firm for your liking. Where this really shines is that it's certified as hypoallergenic and really easy to keep clean, so if you have sensitive skin, you can run this through as many washes as you need to.

As one of The White Company's more affordable offering, the Hypoallergenic Comfort Topper comes with a few compromises. It's filled with polyester, which isn't as helpful for temperature regulation as wool. However, the luxurious cotton casing helps to balance this out, offering a breathable layer under your skin.

What we're currently testing

To stay on top of the game (and the bed), I'm still working on reviewing other mattress toppers. There are three exciting ones that will be strong contenders for this list. Here are my initial thoughts on them.

How we test mattress toppers

At woman&home, every review you read is based on real, in-person testing. Louise, Emily and I have spent years testing mattress toppers from a wide range of brands to create this list. Here’s how we do it.

As a sleep-obsessed writer, I keep a close eye on what’s happening in the world of sleep. If a mattress topper is being talked about, whether it’s a long-standing favourite or a new disruptor, I research it thoroughly before testing begins.

Once shortlisted, one of us sleeps on the topper for 4 weeks (sometimes months). We assess everything from unboxing and setup, including vacuum-packed designs, breathable foams, or sustainable packaging, to how easy it is to get on the bed.

Fit matters, so I note whether it uses straps, elasticated corners, or a grippy underside, and whether it stays put overnight. I also test motion transfer using a glass of water or a weight to see how much movement the topper adds or absorbs.

Then comes the real test: sleeping. I track my sleep over a month, comparing nights with and without the topper. I rotate sleep positions and pay close attention to comfort, support, temperature, and any standout features. Nothing goes untested.

Finally, I compare the topper with similar options on the market, often at a similar price, to assess value for money. I finish by explaining who it suits best, who it doesn’t, and suggesting alternatives where needed, so you can choose with confidence.

You can visit our dedicated page for how we test mattress toppers if you want to find out more.

How to choose the best mattress topper

• Sleep style and firmness: The position you sleep in is the biggest thing to consider when choosing a mattress topper. For example, if you sleep on your side, you'll need a mattress topper that has a cushioned pillow-top so that the hard points of your joints can sink into the surface. Front and back sleepers however will need a firmer surface so your spine does not sag out of shape.
• Material: The material you choose depends on whether you'd prefer a soft or firm bed. If you want something cushioning for joints (side sleepers - we're talking to you), a memory foam mattress topper will be better. If you'd prefer a firmer bed, hybrid and latex mattress toppers are best.
  You should also consider any additional sleep needs like whether you have allergies or tend to sleep hot. Wool and synthetic mattress toppers are more breathable and better for those with allergies. Look for gel or charcoal infused foam toppers and those with cooling bamboo or cotton casing if you suffer from night sweats.
• Size: Selecting the right size for your bed is essential to its performance. If you're unsure about what size your mattress is, it's worth measuring to see make sure your topper will fit correctly and cover all surface area.
• Price: Dr Deborah Lee partner of Get Laid Beds explains that a good mattress topper should 'strike a balance between quality and affordability. While it's crucial to invest in a mattress topper that meets your comfort needs, it's sensible to explore options within your budget to find the best value.' You should also consider the state of your current mattress. Are you looking to buy a topper to prolong it's life, or simply add some extra cushioning as your wear your new one-in? Compare how much money you'll save with a topper vs how much it would be to purchase a brand new mattress.

FAQs

Why use a mattress topper? 

Mattress toppers up comfort-levels on any bed to help you sleep better. Whether the bed you sleep on each night simply isn't as comfortable as you like, you have a spare room, with an old mattress that needs sprucing up for when guests come to stay, or you're going on holiday and can't sleep without your 'creature comforts'. They can alter firmness, offer support to alleviate joint pain and give an old, uncomfortable bed a new lease on life.

Mattresses themselves are built to last a long time, which often explains their high price point. But your sleep-preferences may change sooner than you're due an upgrade. Mattress toppers are a cost-effective way to tailor your bed to what you need now, without having to pay for a brand new bed.

Maybe you're wanting to try out the feel of foam, or wool, or feather. Buying a new mattress is a big investment, and you'll pay the price if you get it wrong - literally. Getting a mattress topper is a great way to try out whether a change in mattress material would work for you.

Should your mattress topper go under or over a mattress protector? 

As Rhiannon Johns, interior designer and head of brand at Piglet in Bed explains, 'when using both a mattress topper and protector, you should put your mattress topper on top of your mattress, followed by the mattress protector. This ensures that not only your mattress is protected, but the topper too, keeping dust mites and bacteria at bay.'

How deep should my mattress protector be?

There isn't a one-number-fits-all recommendation for how thick your topper should be, because every sleep style requires different depths. Most experts will recommend starting with 3-inch mattress toppers and then adjusting depending on how you find it. If your mattress is older, less supportive, and more uncomfortable to sleep on, a thicker topper will be more helpful. A thinner topper will make smaller changes to your mattress, such as temperature regulation. Depending on what you need, your topper will deliver different results.

Can a mattress topper help to revive an old bed?

Experts recommend changing your mattress every ten years, so if yours is past its expiry date, you'll need to invest in a new mattress. However, Mark Temlett, Founder of Naturalmat, says, "if you are struggling to achieve a comfortable night's sleep, consider investing in a high-quality mattress topper. This addition to your mattress will provide extra comfort and support precisely where it's needed. At a fraction of the cost of a new mattress, a high-quality topper can make a remarkable difference, especially when made from natural and organic materials. Allowing you to experience ultimate comfort, breathability and temperature control with every night's sleep."

Can a mattress protector actually help with joint or back pain?

Whilst you should always see a medical professional for back and joint pain, our experts speak from experience when we all say that, yes, toppers can really help. Memory foam can help to provide comfort and cushioning around joints, whilst latex mattresses can help with spinal alignment for back ache. I personally get a lot of joint pain and find that my bamboo topper makes a huge difference.

Are mattress toppers any good for side sleepers?

Mattress toppers can be invaluable for side sleepers. When you don't lie flat, you can create poor spinal alignment, adding unnecessary pressure to your hip, back, and shoulders. Chosen correctly, a topper can help to restore your alignment, redistributing weight more evenly across your body.

Put simply, we only recommend mattress toppers we’d genuinely sleep on ourselves. Whether you’re looking to soften a firm mattress, add extra support, or stay cooler at night, this guide is designed to help you find the right fit for your sleep, backed by real testing, expert insight, and honest advice.
