When it comes to the best soft mattresses in the UK, Brook and Wilde is a tough nut. The brand’s soft Lux mattress has generated quite the hype and has received praise from experts, with leading reviews on the most reliable websites.
This ‘bed-in-a-box’ mattress expands all by itself and has 1,000 bigger pocket springs along with 2,000 small ones giving plenty of support to ensure a good night’s sleep.
The construction itself is quite sturdy and reliable, with six different layers ensuring that your rest is comfortable and uninterrupted. First comes a breathable cover, then the cooling memory foam. The third layer has the 2,000 small springs that move as you turn, reducing pressure points. The fourth is another support foam made with Brook and Wilde’s Wave technology. The fifth layer sports the additional 1,000 larger pocket springs, and lastly, you have the specialized support base foam. Together, these make this the best soft pocket-sprung mattress on the market.
The mattress comes with a 10-year warranty and a 100-day sleep trial, and it’s available in four UK sizes: super king, king, double, and single.
When looking at customer reviews, you’ll be hard-pressed to find anything negative about this product. While it all boils down to personal preference and budget, some people found the medium mattress way too soft for a medium. Then again, if that applies to you too, you can easily swap it with a firmer option.

- Trial: 14 nights
- Price: £1274.95–£1,859.95

The Shine Advanced Softer Mattress from Mammoth might just be your best choice if you’re in the market for soft mattresses for back pain relief. Focused on giving users a bit of a health and energy boost, the Shine collection delivers exclusive comfort via advanced sleep technologies, alongside quality fabrics and fillings.
The Softer Mattress is made with Mammoth’s well-known Medical Grade Foam, and it also sports the brand’s PostureCell technology, with its seven different support zones.
NHS-endorsed Mammoth is the only brand that uses this Medical Grade Foam tech, so it’s one of the go-to choices in the world of sports. This foam block combined with the brand’s PostureCell technology ensures even weight distribution on the mattress and relieves tension on high-stress areas, making it one of the best soft mattresses in the UK.
The depth of the mattress is almost 12 inches, and of that, over 6 inches is the Medical Grade Foam, with the remainder being the brand’s soft-touch SkyFoam. The mattress also comes with a lovely quilted cover and ergonomic handles for easy transport.
The only possible disadvantage of this highly capable soft mattress? Well, the price tag even of the smallest sizes may be off-putting for most. However, as they say, it’s an elite mattress with an elite price ta
3. REM-Fit 400 Sleep Mattress Review

The mattress is also infused with cool gel to keep you from overheating, and the added pocket springs provide great support and comfort.
The mattress itself is 12 inches with three distinctive foam layers to ensure a good night’s sleep. The top is a 2″ comfort layer of adaptive memory foam designed to ensure cooling and provide comfort. The second is a 2.5″ support layer made of the company’s Response Foam. It gives support and helps transition motion between layers. Lastly, there’s a 7.5″ support layer which serves as a base, providing deep compression and support for the user’s body.
All in all, if you’re looking for the best soft mattress under £1,000, the REM-Fit Sleep 400 might do the trick. It’s a fine mixture of softness and firmness, providing the right amount of contouring without letting you sink into the mattress.
The Rem-Fit Sleep 400 is a medium to firm mattress, it comes in five different sizes, and it causes no discomfort or numbness after sleeping, even though it needs a little time to ‘soften up’.
On the other hand, things can get smelly after receiving the package because the model has a moderate amount of off-gassing when taken out of the box. But since the odour usually dissipates after a night, this could be the best inexpensive soft mattress for you.
4. Studio by Silentnight Mattress Review
- Type: Memory foam
- Warranty: 5 years
- Trial: 60 days
- Free delivery
- Price: £399.00–£699.00
- Soft-touch, anti-allergy cover
- Responsive and supportive foam layers
- Quite breathable
- Might be slightly firmer for some than a regular foam mattress
Silentnight is probably one of the best-known mattress brands in the British market. Its products were always thought of as solid choices for people looking for comfort and quality in an affordable package.
Silentnight has also become known for its soft, springy mattress designs. However, the company has also come up with its own soft design to offer customers an even wider variety of choices.
That being said, the Studio is a great contender on the soft foam mattress market, giving buyers the chance to choose between soft, medium, and firm mattress options. Meanwhile, most competitors do not offer this feature.
With its Active Response technology, this mattress is capable of creating a ‘bounce-back feeling’ which helps users move easily over the mattress’s surface throughout the night. It also helps them maintain an undisturbed sleep so they wake up energized.
This soft-to-medium mattress also helps you spread your body weight out evenly, and it will give you support where it’s needed, reducing unnecessary pressure.
The Studio Flex foam core provides support tailored to your body shape. The cover is Allergy UK approved, and it provides a clean, fresh, and healthy sleeping surface. Furthermore, the Geltex inside provides the breathability that’s often missing from memory foam mattresses.
Unpacking it is also easy since it arrives rolled up and boxed. When you receive it, all you need to do is to simply remove the packaging and wait for it to reach its full size.
Lastly, the free 60-night trial enables you to swap your mattress for any other design from the Studio collection if you’re unsatisfied with your current product. That’s a soft foam mattress deal that’s hard to beat.
5. Relyon Classic Natural Supreme Mattress Review
- Type: Pocket-sprung roll-up mattress
- Warranty: 5-year guarantee
- Free delivery
- £471.00–£864.00
- High-quality, durable materials
- Conforms to your body shape
- Excellent edge support
- Slight off-gassing in the beginning
If you’re looking for the best soft-to-medium mattress on the market at a fair price, Relyon’s Classic Natural Supreme pocket-sprung mattress might just be your best option – the 6-foot super king-size model costs just £489.
This particular model sports 1,390 pocket springs, all of them nested individually and moving independently within the mattress. This feature ensures that your mattress is supportive and responsive to your body shape, posture, and size.
Relyon’s Classic Natural Supreme line has a 5-year guarantee, with hydrofresh microclimate control fabric that absorbs the moisture during sleep. The mattress also comes with wool tufts (hand-tufted), providing a nice finish to the overall product.
The Classic Natural Supreme might be the best soft king-size mattress. The cashmere, silk, and wool layers do a tremendous job complementing the pocket springs to ensure high comfort levels and adequate support during sleep.
Also, the mattress comes with rolled-up packaging, making transportation a breeze when walking upstairs or into crowded rooms.
All in all, with a wide variety of options, all sleepers can find a suitable mattress in Reylon’s Classic Natural Supreme Line at a budget-friendly package.
On the other hand, a few users had durability concerns with the product and found it a bit firm for a medium-soft mattress.
6. Sealy Posturepedic Nostromo Latex 1400 Pocket Pillow Top Mattress Review
- Luxury pillow top for more comfort
- Soft, temperature-regulating Tencel cover
- Multi-zoned support
- Might be too firm in the beginning
There are buyers out there looking for things that simply work well. At a reasonable price, Sealy’s Posturpedic 1400 mattress might be the best soft mattress to buy because of the copious amounts of praise it received from expert testers throughout the years.
The mattress comes with 1,400 multi-zoned pocket springs and a latex layer, which adds even more softness and comfort to the overall picture.
The mattress is dubbed ‘Posturepedic’, which basically means that the middle of the mattress is reinforced to give your core and back more support. This makes it one of the greatest picks for people looking for the best soft mattress for back pain. As we already mentioned, this 11.8″ deep mattress also comes with a layer of Innergetic Latex for enhanced pressure relief.
Some reviewers have criticized the fact that the mattress can’t be turned over due to the topper. However, expert testers weren’t concerned about this. What they did mention was that larger individuals might need to get a firmer mattress if they’re looking for more support.
At the same time, some have also mentioned a bit of an inconsistency when it comes to mattress firmness. The website rates the product as ‘soft’ – however, some experts consider it more of a soft-medium mattress.
7. Rest Assured Memory 800 Mattress Review
- Type: Pocket-sprung, memory foam mattress
- Warranty: 5 years
- Free delivery
- Price: £264.95–£464.95
- Body contouring comfort layer
- Very supportive
- Good motion isolation
- No trial period or firmness options
If you’re in the market for a medium-soft pocket-sprung mattress, then the Memory 800 from Rest Assured is definitely worth considering. It’s a price-friendly mattress with all the bells and whistles.
The mattress comes with a memory foam layer for comfort that relieves pressure and also has temperature-responsive features. In addition, the support system comes with 800 independently working pocket springs – all of them zoned to provide stable back, joint, and hip support.
The 10.5″ deep mattress model is single-sided – so there’s no need for flipping – and comes with a micro-quilted finish.
When looking at all other medium-soft mattress reviews in this respective price range, it’s hard to find a similar brand that has received so much praise from users on the internet. The potential downside of this mattress is that it doesn’t feature a trial period, so it might be best to see and test the item before you see it.
It’s also worth noting that it only comes in a medium firmness option. However, most users were very pleased with its comfort and bounciness.
Finally, some have also complained about the packaging and missing buttons.
8. Tempur Cloud Mattress Review
- Type: Foam mattress
- Warranty: 10-year guarantee
- Trial: 100 nights
- Price: £1,379.00–£3,899.00
- Nice level of cushioning
- Washable cover
- Lots of options regarding thickness and size
- Too warm for some sleepers
What’s the best soft memory foam mattress according to astronauts? Tempur is a highly prestigious name in the market, having developed materials for NASA. Being on the richer end of the mattress scene, Tempur claims that its products differ from standard memory foam mattresses. These mattresses distribute and absorb pressure, with minimal motion transfer.
Coming with a 100-night trial, 3 different thicknesses, and 10 different sizes, the Tempur Cloud selection is easy to tailor to your needs and sleeping habits.
Like other foam mattresses, a soft surface and even weight distribution are a must for the Cloud line too. This gives users a weightless, cool feel during their sleep thanks to the mattress’s top-notch technology and temperature-sensitive covers.
The basic Supreme model comes with three distinctive layers, with an extra-soft material on top and two thicker layers underneath for reinforced support and comfort. According to the mattress aficionados, Tempur mattresses are a particularly great option for those who suffer from back pain – the soft surface helps keep the spine aligned perfectly.
Tempur may be a fine choice for those who don’t have budget restrictions. However, buyers should know that the cooling technology for these models costs extra.
On the other hand, when looking at soft mattresses, reviews of this product on the internet mention that the models are either too firm or too hot with the cooling system not being effective enough. These problems question the price tag, and thus, we gave it a noticeably lower rating.
9. Bed Butler Emperor Mattress Review
- Type: Foam mattress
- Warranty: 10-year guarantee
- Trial: 100 nights
- Price: £899.00–£1099.00
- Quality wool, cotton, and horsehair for enhanced comfort
- Exceptional support
- Minimal motion transfer
- Might not be right for those who prefer foam mattresses
Looking for soft mattresses in the UK can be a real hassle, especially if you’re new to the market and don’t know where to start. Luckily, there are quite a few reliable quality brands out there, like Bed Butler.
This brand wants to deliver only the best for its customers at acceptable prices. Enter the Bed Butler Emperor luxury soft mattress with its 2,000 pocket springs carefully sewn into their cotton pockets. The independent pockets give an undisturbed night’s sleep along with great body support and excellent comfort.
The mattress is upholstered with 500 grams of lamb wool and 1,250 gsm of cotton with a layer of teased horsehair and additional cotton and silk layers.
The mattress is 10 inches deep and comes with triple-row, hand-stitched sides.
As far as the best soft mattress in the UK goes, Bed Butler’s Emperor might not be an ideal choice for those who need more modern features. On the other hand, the 10″ depth can also be a letdown compared to other, thicker foam mattresses in this price range.
However, at this price, the king-size option is clearly worth considering.
10. Happy Beds Star Spring Quilted Fabric Soft Mattress Review
- Great value for the money
- Soft mattress with a classic feel
- Quality cover
- Inadequate packaging
If you’re looking for a super soft mattress with a classic feel and a touch of open-spring bounciness, the Star Spring Quilted Fabric Soft Mattress from Happy Beds might be your ideal choice.
The mattress itself is only around 7.8 inches deep – so definitely not the thickest option in this comparison. However, at this price point, anyone in the market for a new and comfortable mattress that doesn’t cost a large amount of money should consider it.
This handmade soft-medium mattress comes in six different sizes and comes deep-quilted with quality upholstered damask fabric covers. As such, the mattress should be rotated and flipped regularly to ensure its longevity.
The product comes with traditional Bonnell springs and classic filling, making it one of the best super-soft mattresses on the British market in the more affordable category.
User reviews are also highly favourable regarding this Happy Beds model, with purchasers praising it for its comfort and quality considering its price range. Some, however, may find it too soft, and the simple polybag packaging might damage the mattress during transport.
How We Chose the Best Soft Mattresses
– Our Ranking Methodology –
How did we choose the best soft mattresses for those looking to make their good night’s sleep even better?
We’ve narrowed down your choices by assessing these mattresses in seven different categories to give you only the best of the best:
Comfort
Comfort should be the backbone of every mattress manufacturer’s business philosophy. Your sleep should be a revitalizing, energizing activity, something you do to recharge your batteries and face the day’s challenges head-on and refreshed.
A comfortable mattress that supports your weight evenly will relieve tension in your body’s pressure points. A good mattress shouldn’t add additional stress during sleep – instead, it should leave your night’s sleep uninterrupted.
With that in mind, we were looking for those types of soft mattresses that encompass everything we listed above to give you the most comfort. Some of these mattresses even go one step further with medical grade memory foam layers to make sure you perform at your best each and every day.
Quality
In our book, quality and comfort go hand in hand. While researching, we focused on brands renowned for using only the best materials without cutting corners.
Low-quality materials are definitely a huge no in our book. Nobody wants to make a pricey purchase and only a few months later end up with a mattress that’s saggy and uncomfortable. That’s why we highlighted only top-quality brands in our best soft mattress reviews.
We made sure that all of the mattresses listed here are made with top-grade foam, come with the best pocket springs or traditional springs, and have excellent cover materials.
Cooling Properties
A hot mattress that makes you sweat and won’t cool you down in the summer heat is a mattress you’d best avoid, especially when you’re one of those hot sleepers who can’t catch a break during the hotter months.
As such, we wanted to make sure that when you’re shopping for the best-quality soft mattress you exactly know what to look for.
Most of the products listed here come with toppers made of materials that absorb extra heat and help regulate your body temperature.
Certificates
Certificates are certainly not a must, but they can ultimately help tip the scale when it comes to choosing between two options.
That being said, we aimed to list a few brands that are known to deliver only the best quality both in terms of construction and materials.
Tempur mattresses, for instance, come with a Space Technology Certificate – being the only pillows and mattresses certified by the Space Foundation. This might not mean much for most, but for some, it could aid in choosing among top-of-the-line soft memory foam mattresses.
Trial Period and Return Policy
When hunting for the best bang for the buck, return policies and trial periods can often make or break a deal.
Most of the brands listed here offer a trial period of up to 100 days (in this case, nights), which is great since it lets you fully test out your purchase. In the end, you can still return your mattress if you’re dissatisfied with it.
Apart from looking at the trial periods, we’ve also scrutinized these brands’ return policies. In our book, the best medium or soft mattress manufacturers should have a reasonable return policy. However, based on the customer reviews online, the process can sometimes be a hassle – so whichever mattress you choose in the end, make sure to carefully read the small print.
Warranty
A solid warranty should be a must-have feature. Unfortunately, defects do happen, and sometimes we end up buying brand new items that are faulty. On the other hand, the warranty should give you peace of mind, ensuring a peaceful night’s sleep for a few years ahead.
As such, we focused on brands that offer at least a five-year warranty period, along with a lengthy trial period.
Price
As you can see, we aimed to include different prices in our list of the top 10 soft mattresses to cater to all kinds of budgets. We’re aware that not everyone wants to spend more than £1,000 on a mattress, so we aimed to list products across a broader budget range.
Our goal was to highlight the best of the best from a broader spectrum. However, as you can see, the more renowned brands sport more sophisticated materials, comfort, and cooling technologies, meaning you should be prepared to pay a bit more if you really want to get a good-quality mattress.
How to Choose Among the Best Soft Mattress
– Buyer’s Guide –
With a myriad of choices, finding the right soft mattress can be a daunting task. There are many things to assess and a lot of questions to ask. How soft should it be? Is it right for me? Can there be such a thing as too soft? Will it support my body weight? Will it be comfortable? Will it ease my aches and pains?
With so many questions, let’s get started right away.
First of all, there’s a common myth out there stating that softer mattresses don’t give enough support because they can’t provide proper pressure relief and spinal support. As you can see from our list, all of the mattresses here debunk that myth and use advanced technology to support one’s weight evenly. As such, they provide proper spinal alignment during sleep.
Types of Soft Mattresses
Even the softest mattresses come in different types, and in this section, we’ll guide you through each of them.
Foam
Foam mattresses are probably among the most popular options if you want a soft mattress. They’re usually made of memory foam, polyurethane foam, or a mix of the two.
Traditionally, foam mattresses give users a more ‘sinking’ feeling. They aren’t necessarily plush, but they’re very responsive, and they can have a wider range of firmness – from soft to medium-firm profiles.
Latex
These mattresses are a combination of all-natural foam and latex to form a supportive surface. Regarding softness, they offer the least plush or soft feeling. Their softness will usually depend on the top layer’s firmness.
Innerspring
These soft mattresses are best described as traditional mattresses. The inner coils deliver that bouncy feeling most of us know so well. These models have better edge support most of the time, so they may be a better choice for couples who are on the market for a new mattress.
Just like their latex counterparts, innerspring mattresses aren’t that soft by default. Nevertheless, manufacturers are adding different comfort layers to them to give a softer feeling.
Hybrid
Hybrids combine the bounciness and support of traditional coils and the comfort and softness of memory foam. These features make them an ideal choice for those who suffer from pains and aches but like softness and contouring.
With different comfort layer options on top of the coil base, a hybrid mattress comes with different firmness levels, making it the best soft mattress for side sleepers looking for plushness, comfort, and support at the same time.
How to Choose Depending on Your Sleep Position
Seeing the word ‘soft’, most buyers instantly think of sleeping comfortably and soundly in the clouds. However, there are shoppers who find certain mattresses to be too soft, without providing enough support.
As such, here are the sleepers who should consider investing in a soft mattress:
Lightweight Sleepers
Soft memory foam mattress reviews often state that those who have a lower body weight and are looking for comfort can benefit greatly from a soft mattress since they can’t really sink into traditional and firmer mattresses. A really soft mattress provides the pressure relief, the soft feeling, and the comfort they’re looking for.
Side Sleepers
Sleeping on your side impacts different pressure points around the shoulders and hips, and as such, a softer mattress can help fight the resulting pain. A soft mattress can also help fight the numbness and tingling sensations that come from one’s arms or hands getting tucked under the body. With this in mind, we’ve put together a great list for those looking for the best soft mattress for side sleepers in the UK.
Sizes
A soft mattress can come in any traditional size, like single, double, king size and even super king size. Some makers even offer custom sizes out of the box.
Soft Mattresses – Pros and Cons
Pros:
- The level of softness and comfort these mattresses provide makes them really inviting, convincing you to curl up in bed every night. High-quality models tend to have a rather luxurious feel to them, making them even more desirable.
- The best soft mattress tackles side sleeper problems with ease by aligning the spine. The top layers usually have enough give to allow the shoulders and hips to get enough support without putting pressure on them.
- They can help with general back pain and joint problems. However, you need to find a mattress with enough support to keep the spine in the right position and enough plushness to keep you comfortable.
Cons:
- If the mattress is too soft, it can lack the support that people with regular neck, hip, and back pain need. They should consider a firmer soft mattress if they opt for buying. There has been an ongoing debate about whether soft mattresses are bad for back pain or not, but it will mostly depend on the severity of the pain. Those who have chronic back pain would benefit more from a medium or firm option.
- Some of the softest mattresses can lack edge support and make moving around difficult for couples. Just like in the case of those who suffer from back pain, a firmer option might be more suitable.
- Large and tall sleepers should also avoid a super soft mattress because they might end up feeling unsupported and generally ‘swallowed’. Because of their frame, they’ll benefit from a firmer mattress because they need more support.
Wrapping Up
All in all, this is everything you need to know about buying a soft mattress. We particularly focused on the different types and sizes, as well as their pros and cons. Hopefully, this article covering the best soft mattresses UK sleepers want will help you reach an educated decision before making a purchase. More than anything, we want to help you improve not just your sleep but your overall quality of life.
FAQs
What is the best medium-soft mattress?
In our book, hybrids might just be the best of both worlds. They’re ideal for those who want the contouring, comfort, and soft feel of a foam bed but still want the proper support of a more traditional mattress with springs.
Are soft mattresses better for side sleepers?
As already discussed above, a soft mattress can help alleviate pain and pressure in the hips and shoulders for those who are used to sleeping on their sides on a firmer mattress. They can also ease any numbness for sleepers who tuck their hands under their body during sleep.
What is the best soft mattress to buy?
This answer mostly boils down to personal preference. For most people, it will be memory foam mattresses. Meanwhile, those looking for more support will either opt for hybrids or latex mattresses. Price is also a determining factor, so those who are on a tighter budget will likely look for traditional innerspring options with a soft top layer.
