If you can’t afford to buy a glorious new mattress and already have a good pillow, the best mattress toppers offer a quick and relatively cheap way to improve the quality of your sleep. They’re also far more portable than a mattress, which is handy if you’re renting a furnished property. Recent years have seen huge technical advancements, with new types of springs to help with back pain and even graphite to regulate temperature.
Big names like Simba, and Emma, famous for making the best mattresses, all make mattress toppers too. Over the last few weeks I’ve tested all of them, including memory foam mattress toppers, wool mattress toppers and hybrid mattress toppers. You’ll find my full reviews further down this article along with answers to frequently asked questions, including how to clean them and stop them from sliding. But if you’re in a hurry, here’s a quick look at my top five:
Which is the best mattress topper? At a glance
- Best mattress topper overall - Emma Premium Mattress Topper
- Best value mattress topper - Silentnight Airmax Double Mattress Topper
- Best mattress topper for back pain - Simba Hybrid Topper
- Best soft mattress topper - The White Company Classic Mattress Topper

How to pick the best mattress topper for you
“A good mattress topper will be very firm and dense, usually 5lb and high-density latex foam,” says Penny Albright, founder of the Easy Sleep Guide. “These toppers help because they create a bit more surface pressure, supporting your body and back.”
Look out for material, firmness, thickness, size and durability, says BSM-certified sleep expert and consultant at Mattressive, Nicole Eichelberger. “A bad quality mattress topper may be made of inferior materials, have a poor level of firmness, be too thin or too thick, be the wrong size for your mattress, or be poorly made and prone to breaking down quickly. It is important to do your research and choose a topper from a reputable brand to ensure that you are getting a good quality product.”

How we chose the best mattress topper
The three main things I was looking for in a mattress topper were that it should be comfy, cosy and supportive. I wanted to feel like I was melting into the bed and to be able to move around in the night without feeling lumps or bumps. During the night, I wanted to wake up as little as possible and in the morning, not feel any back or neck pain from poor support.
I tested the mattress toppers below for two weeks each in winter and summer, so temperature regulation and breathability were important. The mattress toppers with more advanced temperature regulation technology like Emma’s graphite coating and Simba’s open cell foam technology performed better. Here is what I found, starting with my favourite.
Best mattress toppers
1. Emma Premium Topper
£279 for a double, Emma
Best foam mattress topper, 9/10
We like: the nine inches of height
We don’t like: it’s bulky to store
- Foam topper
- Single, small double, double, king, super king sizes available
- 9cm depth
- 10 year warranty
- Washable cover
Emma has nailed it with this supreme mattress topper, which really is Diamond Degree. It’s the best mattress topper for temperature regulation thanks to the graphite coating, which promises a longer deep sleep phase. The lower layers include an adaptable HRX foam layer for comfort and pressure relief in any position, and a breathable, elastic cover to keep everything in place.
As is the Emma way, this mattress topper arrives packed into a compact box, rolled as tight as possible for easy transportation and storage. As I unrolled it on my bed, it expanded straight away. No need to wait a couple of hours as you do with bed-in-a-box mattresses. To put its 9cm depth into context, it’s almost half the depth of my actual mattress.
Though the foam is firm, it doesn’t have the problem some memory foam toppers do, which to make it difficult to change positions in bed. Instead, it’s supportive and flexible. I would hesitate to pay the full price for this mattress topper (£500), not because I don’t think it’s a great product, but because I’m not sure any mattress topper should cost more than a mattress – and you can certainly get decent mattresses for £500. Thankfully, the Diamond Degree is sold at half price for much of the year.
2. Silentnight Airmax Double Mattress Topper
£31.24 for a double, Amazon
Best value mattress topper
We like: it’s well-priced for how comfortable it is
We don’t like: it’s thinner than more expensive mattress toppers
- Polyester topper
- Single, small double, double, king, super king sizes available
- 5cm depth
- Two year warranty
- Machine washable
This Silentnight topper refreshingly costs less than £50 but still provides the comfort needed to boost an old mattress. Instead of fancy materials like other brands, it relies on one simple concept: air.
The Airmax technology uses mesh sides to maximise airflow and prevent any trapping of heat. It creates pockets of air throughout the mattress topper to prevent any overheating. The rest of the topper is filled with hollowfibre for comfort.
I found the Silentnight to be slightly thinner than it looks online, but it’s still padded enough to be extremely comfortable. I tried it on an old mattress that I can usually feel the springs through and it took away any discomfort. It softens the surface, without adding so much extra height that you need a new fitted sheet.
If you’re looking to add a little softness to a hard mattress without blowing your budget, this is the one to try.
3. Simba Hybrid Topper
£289 for a double, Simba
Best mattress topper for back pain, 9/10
We like: it’s firm and supportive
We don’t like: it starts off too firm and needs breaking in
- Hybrid foam and spring topper
- Single, small double, double, king, super king sizes available
- 7cm depth
- 10 year guarantee
- Washable cover
Simba mattresses are widely considered the best on the market and their Hybrid Pro duly topped our list of the best mattresses. This mattress topper is the more pocket-friendly alternative. Like the mattress, it’s a firm option for maximum support, thanks to four layers and up to 2,500 ‘Aerocoil’ springs.
The layers include a soft, breathable sleep surface, a cooling foam layer for comfort, a spring support layer and a foam base that uses Simba’s patented open cell foam technology. It has a less dense structure than traditional memory foam and better regulates air flow.
The mattress topper arrived, tightly rolled up inside an upright cardboard box. I’ll admit the size of the box was pretty daunting at first but inside, the mattress is rolled to a compact size and kept in place using the same straps used to keep it on a mattress. After rolling it out on my bed, it took about 15 minutes to plump up to full size as the air seeped into the foam. The non-stick bottom is excellent.
The first night I slept on the topper, I found it a little firm, as is generally the way with memory foam mattresses. After that, it softened and adapted to my body. My daily routine would send an osteopath running scared – an hour each morning and evening on a train, with eight hours at a desk in between – but sleeping on such a supportive mattress topper has ironed out any aches and stiffness. It may come with a hefty price tag, but the forward-thinking technology, eco-friendly materials and pure support is unmatched.
4. The White Company Classic Mattress Topper
£120 for a double, The White Company
Best soft mattress topper, 8/10
We like: you literally sink into it
We don’t like: it gives very little support
- Feather and down topper
- Single, double, king, super king
- 5cm depth
- No warranty, but exchangeable if faulty
- Machine washable
The White Company’s Classic Mattress Topper really does enshroud you in a cloudlike surface when you lay down into it, with the quilted design embracing you like a warm hug. The inner layer is made of 100 per cent duck feathers and the top layer is an even softer mix of duck down and feathers. The casing is 233 thread-count cotton percale and all the materials are carefully sourced from cruelty-free suppliers.
This is definitely a soft mattress topper. Don’t lie on it expecting maximum support and for it to fix a sore back. What it does instead, is envelope you into the bed as the quilted surface tufts up around your body. I loved sleeping on it, though personally I do need a little support for my back.
Here’s where I let you in on a little tip. I’ve been sleeping on The White Company’s Comfort Mattress Topper, on top of the Simba Hybrid topper. It creates the perfect medium firmness, with the support from the Simba felt through, and The White Company taking the edge off the slight hardness.
5. Duvalay Comfort Mattress Topper
£189.95 for a double, Duvalay
Best topper for refreshing an old mattress
We like: the comparatively low price for a memory foam topper
We don’t like: it’s probably too thin for stomach sleepers
- Memory foam topper
- Single, small double, double, king, super king sizes available
- 5cm depth
- Machine washable cover
The Duvalay story actually started with a solution to sleeping uncomfortably in caravans. Husband-and-wife founders Liz and Alan Colleran were tired of waking up from sleeping on holidays with a bad back. In 2011, they took a memory foam sleeping bag to Dragon’s Den and secured funding from Hilary Devey.
These days, Duvalay produces bedding both for caravans and normal beds. This Comfort Mattress Topper is for regular bedding. Trust me - it’s so big, even rolled up, it would take up half a caravan.
It’s made out of memory foam mainly consisting of polyester and viscose. I actually think it’s very well priced for a foam mattress topper, compared to Emma and Simba options higher up this list.
Unlike other memory foam toppers, it doesn’t overheat. It’s also thinner than most other mattress toppers, at 5cm. But it still provides the immediate pressure-relieving, sinking feeling when you lie into it. It’s perfect for anyone wanting an upgrade without investing in a whole new mattress.
6. Dunelm Rebound Mattress Topper
Currently £36 for a double, Dunelm
Best budget mattress topper, 7/10
We like: low price for a very decent topper
We don’t like: it’s not the most sustainable option
- Polyester topper
- Single, small double, double, king, super king
- 5cm depth
- Machine washable
The Dunelm Rebound Mattress Topper takes the prize for the best budget mattress topper. For less than half the price of most others, it still adds 5cm of depth to a mattress and is surprisingly comfortable. I’d liken it to The White Company’s Comfort Mattress, but made of cheaper materials.
The Rebound is made from polyester and the inside is polyester hollowfibre, which is lower quality than the more high-tech materials of other toppers – but I’ve owned this Dunelm mattress topper for three years, sleeping on it most nights, and it still holds a spring and adds a crucial layer of comfort to the mattress in my rented flat.
It’s best suited to autumn or winter, because the material heats up and is less breathable than other fabrics. Yes, there are better mattress toppers above. But this is a decent choice for a spare bed, a University bed, or just someone looking for a cheaper option.
Mattress topper FAQ
What is a mattress topper?
A mattress topper sits over your mattress to add support and comfort. It can be made of different materials including foam, latex, down, feathers, wool and polyester. It can prolong the life of a tired mattress by taking pressure off its springs, and often costs far less than buying a new mattress.
What is the best mattress topper for back pain?
A firmer mattress topper, like the Simba Hybrid or Emma Diamond Degree will probably be best: the Easy Sleep Guide’s Penny Albright says that if you have back pain, you may have to sacrifice some comfort for support.
“It is recommended that people with back pain should sleep on something firm,” she says. “Products that are too soft can worsen already existing back pain and cause pressure points in other parts of your body. While you feel like you might be uncomfortable sleeping on a firmer topper, it could help your back pain in the long run.”
Sleep expert Nicole Eichelberger points out that this can go both ways. “A mattress topper that is too firm may not provide enough cushioning and may be uncomfortable for some people. It is important to find a mattress topper that provides the right balance of support and comfort for your individual needs.”
How do you clean a mattress topper?
Lots of mattress toppers these days have covers which can go straight in the washing machine. Alternatively, water and white vinegar in a spray bottle is a great disinfectant spray to clean a mattress topper, combined with a cloth to gently wipe down. For stains, try using baking soda mixed with water, or trusty Vanish.
How do you stop a mattress topper from sliding?
The vast majority of mattress toppers come with elasticated straps which loop under the mattress at each corner. Not all, though – including the Emma mattress at the top of this list, which relies on a grippy bottom. If you’re still struggling, try a tightly fitted sheet to secure it in place.
Which mattress toppers are made from sustainable materials?
Simba prides itself on its sustainability by using all biodegradable, renewable or recyclable materials for its mattress toppers which are made in zero waste factories in the UK. More specifically, the mattress topper in the above review is made from biodegradable, organic latex, recyclable springs and recycled hollow fibres.
If you want a sustainable mattress, the materials to look for are latex instead of foam, wool instead of polyfibre, and overall a high percentage of organic and natural ingredients.
