Best Orthopaedic Support

Sealy Steeple Ortho Plus Mattress

The Sealy Steeple Ortho Plus Mattress is designed to offer extra-firm orthopaedic support.

With its coil spring core and mesh edges, this firm mattress keeps air flowing so heat doesn't become trapped.

Crafted in the UK, the Sealy Steeple Ortho Plus has an extra-firm feel.

The orthopaedic mattress features postureTech Core Support Springs, designed to offer dynamic lumbar support, becoming firmer as more pressure is applied. 💪

Its spring core works with the mesh edge of the mattress to enhance breathability for a cooler sleep.

The 29 cm (11.5 inches) mattress also boasts EdgeGuard foam for consistent edge-to-edge support, while the hand-tufted top increases durability and firmness.

Sealy extra firm steeple ortho mattress
The mesh edge and coil spring core allow air to flow freely, helping you stay comfortably cool.

The mattress is double-sided with 4 handles on its damask cover, designed so that you can easily flip the mattress.

Sealy recommends turning the mattress every 3 months to extend its lifespan.

While most Sealy Steeple Ortho Plus mattress reviews point to the mattress being comfortable, it's not for everyone.

It is less suitable for couples as it doesn't offer great motion isolation, meaning you can feel when your partner moves during the night. 😧

Luckily, the mattress comes with a reassuring 60-night trial through Mattress Online, so you can swap it if you don't love it.

It also comes with a 5-year guarantee and the eco-friendly bonus of being 100% recyclable.

Composition: Coil spring core, EdgeGuard foam, damask cover 
Firmness level: Extra-firm
Height: 29 cm (11.5 inches)
Trial period: 60 nights

Luxury Option

Sealy Winslow Geltex 2400 Pillow Top Mattress

The Sealy Winslow Geltex 2400 Pillow Top Mattress is luxuriously thick, supportive, and breathable.

Layers of pocket springs and Geltex offer customised support and pressure relief where needed.

The Sealy Winslow Geltex Enhance 2400 Pocket Pillow Top is a luxurious 31 cm (12.2 inch) thick mattress.

Exclusive to Mattress Online, it offers a balanced medium-firm rating.

Its construction boasts a two-tier core, with 1000 primary pocket springs and an additional 1400 mini pocket springs.

Since pocket springs are individually wrapped, they can move independently to offer tailored support and prevent the 'roll-together' effect you get with some mattresses. 🛌

Topping off the pocket spring core is a Geltex layer.

Geltex provides excellent pressure relief with better breathability and a quicker rebound than traditional memory foam.

The pocket spring and Geltex combination provides enhanced temperature regulation, though some customers said it wasn't enough to keep them cool.

Sealy winslow geltex mattress
The Sealy Winslow Enhance 2400 Mattress features a soft pillow top, adding to the comfort of the mattress.

While breathability is central to the Sealy Winslow mattress, it also features a pillow top layer and soft knit fabric cover to achieve a soft-to-the-touch feel.

Although single-sided, the mattress is built with convenience in mind, sporting four handles for easy rotation.

Customer feedback is generally positive, praising its robust build and quality. 👏

However, it's not for everyone, and some customers noted it felt firmer than its medium feel label.

It's also disappointing that a mattress at this price only comes with a 5-year guarantee.

Made in the UK, the Sealy Winslow Geltex 2400 Pillow Top Mattress also comes with a 60-night trial through Mattress Online.

Value For Money

Sealy Mellbreak Ortho Plus Mattress

The Sealy Mellbreak Ortho Plus Mattress has a firm feel and a unique open coil core, ideal for back sleepers.

This double-sided mattress also features edge-to-edge support and tufting, making it a highly durable and long-lasting choice.

Manufactured in the UK, the Sealy Mellbreak Ortho Plus is a firm-feeling mattress.

The PostureTech Core Support spring system is unique in that its coils are engineered to respond to pressure, becoming firmer in places the body requires enhanced support. 👍

It is also fitted with what Sealy calls 'PowerPack' comfort, an area of more densely packed springs in the centre of the mattress designed to enhance lumbar support.

The spring core and firm feel make the Sealy Mellbreak Ortho Plus Mattress well-suited to back sleepers

While the Sealy Mellbreak Ortho Plus Mattress offers the right support for back sleepers, it is too firm for most side sleepers.

The tufted surface, double-sided design, and EdgeGuard technology, which promotes edge-to-edge support, work together to create a firmer feeling and more durable product.

If you are concerned about the environment, you'll be pleased to know that the mattress is 100% recyclable.

While the majority of Sealy Mellbreak Ortho Plus reviews praise its accurate description and value for money, a few customers have reported premature sagging. ⚖️

Thankfully, such issues are rare and are covered under the mattress guarantee.

The Sealy Mellbreak mattress has a 60-night trial and a 5-year guarantee, both ensuring peace of mind, critical for buying online.

Crafted in the UK, this mattress is well-made and long-lasting.

The Sealy Claremont Memory Advantage Mattress has a balanced, medium-firm feel.

Standing at 27 cm (10.6 inches) thick, it might not be the tallest mattress, but it promises a supportive night's sleep.

It is crafted with PostureTech Core Support Springs, a special feature that gets firmer when more pressure is applied, ensuring targeted support. 🎯

The mattress is topped off with memory foam fillings, excellent for pressure relief and reducing restless nights.

It is also a greener option since it is 100% recyclable and highly durable due to its quality craftsmanship and Edge Guard technology. 🌱

You'll want to regularly rotate the mattress, using the attached side handles, to further prolong its lifespan.

It's worth noting that some customer reviews suggest it feels slightly softer than described, leaning more towards medium than medium-firm. 🤔

A few also mentioned a tendency to roll towards the centre or off the edges.

Fortunately, Mattress Online offers a 60-night trial and a 5-year guarantee, so you have some time to decide if it's the right fit for you.

Who is Sealy?

Sealy began in 1881 in Texas, USA.

Over the years, this brand evolved to claim the title of the world's biggest bed brand. 🏆

Although an American original, every Sealy mattress destined for a UK home is manufactured in the UK.

While it was owned and managed by Silentnight for 47 years, the Sealy beds brand now operates under Tempur-Sealy after merging with Tempur in 2012.

Sealy has continued to grow over the years, placing increasing importance on enhancing its products.

Experts doing research
Sealy is proving their dedication to helping customers sleep better with a newly opened research and development facility and partnerships with Orthopaedic specialists.

In 2021, Sealy revealed its new Australian research and development facility, where it explores new mattress technologies. 🔍

The brand also consults the International Orthopaedic Advisory Board [1] during product development.

Given these facts, it’s no wonder most customers speak highly of Sealy mattress quality!

Now we know a bit about the brand, let’s learn more about their mattresses. 👇

Sealy mattress selection

When it comes to the Sealy UK mattress collection, it makes sense to start at the source - the Sealy website [2].

Here, Sealy offers two core options.

These include:

  • Sealy Posturepedic mattresses.
  • Sealy Classic mattresses.

Of course, these names aren't necessarily self-explanatory, so let's take a closer look. 🕵️

Sealy Posturepedic mattresses

First, let's talk about the most popular and often considered best Sealy mattress UK collection - the Sealy Posturepedic range.

What is a Sealy Posturepedic mattress?

In a nutshell, this mattress aims to help your spine stay neutral during sleep.

Optimal spinal alignment
A mattress should help align your spine, ensuring you don't wake up plagued by back pain.

The Sealy Posturepedic mattresses also aim to reduce muscular tension and pain by providing better support. 🛌

But how do they do that?

Well, the AlignSupport Coils offer responsive and deep support, ensuring weight is evenly spread over the mattress surface.

They are also twice-tempered to improve the coil's resilience! 💪

It also has reinforced 'UniCased XT' edges, designed to combat the sensation of rolling off the mattress and help maximise every inch of your mattress.

Edge support
The edge support offered by Sealy Posturepedic mattresses means your mattress shouldn't sag even if you're resting by the edge.

The core coils and edge support are further strengthened by the robust BasePlank, which provides a firmer foundation. 🤝

Finally, Sealy Posturepedic mattresses are topped off with comfort layers to ensure you're well-supported and comfortable.

If you suffer from back pain, this range is well-suited to you.


What's included in the Sealy Posturepedic mattress range?

The Sealy Posturepedic range is divided into the Elevate and Elevate Ultra collections. ✌️

Both collections are similar and make use of Sealy's Posturepedic technology.

Sealy Posturepedic Elevate mattresses combine Posturepedic technology with foam for a less bouncy and more pressure-relieving finish.

Meanwhile, Sealy Posturepedic Elevate Ultra mattresses also feature a MemorySense Comfort Core and a cooling gel-infused layer. ❄️

Gel mattress
Mattresses with gel layers sleep cooler are ideal for a hot sleeper.

Sealy Posturepedic mattresses come in soft, medium, or firm options.

This selection of mattress firmness is beneficial since different people need different levels.

For instance, side sleepers need a much softer mattress, which allows their hips and shoulders to sink in to keep a neutral spinal alignment. 🤗

Back sleepers need something firmer, and stomach sleepers need the firmest mattress.

Best mattress firmness for different sleep positions
Your sleeping position affects the level of mattress firmness you'll need.

Furthermore, smaller and lighter sleepers need a softer surface than larger and heavier individuals, who need something firmer that stops them from sinking through it.

Sealy classic mattresses

Beyond the famous Posturepedic mattresses are the various Sealy Classic mattresses.

Sealy Classic mattresses (and their standout features):

  • Sealy Hybrid mattresses: Combining reinforced edges and a gel-infused comfort layer.
  • Sealy Enhance mattresses: Focusing on a pressure-relieving gel-infused layer.
  • Sealy Advantage mattresses: PostureTech Core Support, where coils get firmer as pressure is applied.
  • Sealy Advantage Deluxe mattresses: PostureTech Core coils, gel-infused comfort layer, plush top layer.
  • Sealy Ortho Plus mattresses: Firmer feeling mattresses with PostureTech Core and PowerPack centre for additional lumbar support.

The Sealy Advantage mattresses and Ortho Plus mattresses are among the brand's best sellers. 🥇

Most of these mattresses are available in at least two different firmness options, ranging from medium-soft to firm.

Sealy Ortho Plus mattresses also come in extra firm.


Where to buy Sealy mattresses

Sealy manufactures an impressive range of mattresses.

Unfortunately, it can be pretty confusing trying to navigate what’s on offer. 😵‍💫

Lucky for you, we’re here to demystify things!

Firstly, Sealy UK doesn’t sell its mattresses directly (in stores or online).

So, to purchase one of the best Sealy mattresses in the UK, you’ll need to look at one of their approved retailers.

These include:

While this isn’t uncommon, it does lead to some complexities.

For instance, while some Sealy beds are exclusively sold through one retailer, many of their best-selling mattresses can be found with various retailers.

Frustrated and confused woman
Finding a Sealy mattress can be confusing, especially if you have a particular Sealy mattress in mind.

Additionally, retailers sometimes use different names.

Fortunately, while the names vary, they will still include the essential information such as whether they are a Posturepedic or Ortho mattress. 😀

If you want to try your mattress before you buy it, check out a physical retailer like Dreams.

Alternatively, you can enjoy a 60-night trial and (at least) a 5-year guarantee if you buy a Sealy mattress from Mattress Online.


What materials do Sealy mattresses use?

Sealy uses a variety of materials to create their mattresses.

Some of the most common materials used in Sealy mattresses include open coils, pocket springs, foam, and gel-infused foam.

Each of these materials offers specific benefits.

Let's investigate these in more detail to see which mattress materials will help you get the best night's sleep. 🤔

Sealy open coil mattresses

Traditional coil mattresses offer firm support but don't usually have great point elasticity or pressure relief. 🌀

While Sealy beds use open coils, they have adapted the design to improve the support and pressure relief offered.

At Sealy, there are two standout patented open coil systems.

These include:

  • AlignSupport Coil system.
  • PostureTech Core Support.

These coils promise firm support at the centre and from edge to edge! 🛌

Sealy also pairs their coils with comfort layers to enhance comfort and ensure customers don't feel the coils in their mattresses.

One of the most popular mattresses is the Sealy Blackwood Elevate Posturepedic mattress, which combines AlignSupport coils and Reflex foam for a more supportive, firm, yet pressure-relieving feel.


Sealy pocket sprung mattresses

With pocket spring mattresses, each spring is nestled in its own pocket.

This means they move independently, giving tailored support and improving pressure relief. 🕺

Sealy often blends these springs with other materials.

Pocket spring mattress
Pocket springs move independently, meaning you are supported as and where you need it most.

The renowned Sealy Winslow Geltex Enhance 2400 Pocket Pillow Top Mattress is a prime example of combining materials for the ultimate sleep experience. 🛏️

It layers 1000 pocket springs with an additional 1400 mini pocket springs.

This Sealy pillow top mattress tops it off with a breathable Geltex layer, delivering a cool, responsive and pressure-relieving sleep experience.


Sealy foam mattresses

You may be disappointed if you're looking for a 100% Sealy memory foam mattress.

Sealy doesn't sell any pure foam mattresses.

However, they do use foam layers in several of their mattresses.

Foam vs spring mattress temperature
Foam mattresses tend to sleep warmer, affecting sleep for some people, especially warmer sleepers.

Foam tends to be highly responsive, hugging your body and relieving pressure points, but retains heat, making it less suitable for hot sleepers.

To combat this, Sealy often uses temperature-regulating gel-infused foam in combination with open coil and pocket spring cores, which promote airflow.

Gel mattresses typically have better heat-diffusing properties than traditional foam or memory foam mattresses.

However, it is worth noting that some customers have said gel mattresses like the Winslow Sealy Geltex mattress don't sleep as cool as they'd like.

How comfortable are Sealy mattresses?

Mattress comfort is very personal, and what's cosy for one might not be for another. 🤷‍♂️

Having said that, Sealy collaborates with orthopaedic experts and invests in some top-tier tech for their mattresses.

Their primary goal is to ensure your spine remains aligned while you dream.

Happy woman sleeping
Sealy mattresses are developed with the help of experts and with added comfort layers for a more padded and comfortable feel.

Most Sealy UK mattresses include 'comfort layers' to add a cosy touch to your sleep experience.

Many folks praise how comfy their new Sealy mattress is, and some even comment that it helped reduce (or eradicate) their back pain. 🎉

But it can take a week or two to adjust to a new mattress, and not all Sealy mattress reviews are sunshine and rainbows.

Some customers have reported sagging, lumps, or springs poking through their Sealy mattress.

Luckily, these issues are due to product faults and are, therefore, covered under the Sealy guarantee.

Sealy mattress firmness

Mattress firmness is a critical consideration when talking about comfort.

While Sealy has a small selection of medium-soft and softer options, most Sealy mattresses tip towards the firmer side, especially those within the Ortho Plus collection.

For side sleepers, especially the more petite, Sealy mattresses may feel a touch too firm. 🧱

If you want a softer mattress, you may prefer to shop outside the Sealy range.

The Emma Original Plus is an excellent option for those wanting something softer that will still help keep your spine aligned so you can sleep comfortably.


It’s also worth noting that there’s some debate among sleepers about how true-to-description Sealy's firmness ratings are. 🌙

Among Sealy mattress reviews for the same product, for instance, the Sealy Mellbreak mattress, some customers say it feels too soft, while others argue it’s firmer than expected.

Different degrees of firmness
Understanding how firm a mattress is without trying it can be difficult, and not everyone agrees with Sealy’s firmness ratings.

Having said that, it’s worth remembering that weight plays a sneaky role here. ⚖️

Smaller individuals tend to find the same mattress feels firmer than someone heavier would.

We suggest checking Sealy mattress reviews for your desired product before purchasing it to ensure it’s generally well-rated and fits your personal preferences. 🤔

If you’re looking for a firmer mattress, we’ll say that most customers love the Sealy Steeple Ortho Plus Mattress for its comfort, support, and quality.


Who are Sealy mattresses most suitable for?

Sealy mattresses are generally well-rated, but they’re better suited to some individuals than others.

So, who should consider getting a Sealy mattress? 🤔

People seeking firmer support

Generally, Sealy leans towards the firmer end of the spectrum.

Their Ortho Plus collection, in particular, ranges from medium-firm to extra firm.

This makes Sealy Ortho Plus mattresses ideal for people who prefer a more robust and supportive mattress feel. 💪

The Sealy Steeple Ortho Plus mattress, a top contender for the title of best Sealy mattress in the UK, is one of the firmest in the Sealy collection.

With its PowerPack design, this Sealy extra-firm mattress gives additional lumbar support and is ideal for those seeking orthopaedic excellence.


Individuals with back pain

Individuals with back pain can find relief with Sealy's emphasis on posture-supportive technology.

Woman with back pain
Both Sealy Posturepedic mattresses and Sealy Ortho Plus mattresses are especially well-suited to those who suffer from back pain or other related problems.

Sealy mattresses are developed with the help of orthopaedic experts.

Customers have mentioned reduced back issues after switching to a Sealy mattress. 🌟

A recent study revealed that medium-firm mattresses improved sleep quality and spinal alignment [5], particularly for those struggling with lower back pain.

In particular, the Sealy Posturepedic Elevate Blackwood Mattress has worked wonders for many people with back pain.


People with allergies

While not all Sealy beds are the same, some have features designed to help those with allergies get better sleep.

Woman with allergies
If you have allergies, it’s worth investing in a mattress that uses hypoallergenic materials or treatments to ensure you’re not left sneezing the night away.

For instance, the hypoallergenic ProShield® fabric treatment used on the Sealy Blackwood Elevate Posturepedic Mattress helps reduce the chance of an allergic reaction. 🤧

This mattress is an excellent pick for those who have allergies or are sensitive to common irritants.

Those with small to large budgets

There's a Sealy mattress for you, no matter if you’re working with limited funds or want to splash a little more cash to get the best night’s sleep.

The Sealy Mellbreak Ortho Plus Mattress is one of the brand’s most affordable. 💷

It is ideal for back sleepers on a budget, particularly those who want a firmer-feeling mattress that offers dependable, deep support.


Who are Sealy mattresses not ideal for?

While Sealy mattresses are generally considered a safe bet, it’s important to note that not everyone loves them.

So, who should avoid Sealy mattresses?

People who need a more flexible trial

Sealy's mattress trials aren't the longest. ⏳

While retailers like Mattress Online offer a decent 60-day trial, allowing you to test a Sealy mattress at home, not all retailers offer this.

Additionally, these trials usually only allow you to swap your Sealy mattress for an alternative rather than get a full refund. 😒

Those wanting more flexibility should look elsewhere.

Other sleep brands offer much better trials.

For instance, DreamCloud provides customers with a revolutionary year-long trial, during which customers can return their mattress for a full refund if they don’t love it. ❣️


Those who want a longer-lasting mattress

Most Sealy mattresses only come with a 5-year guarantee.

While some Sealy mattresses will last much longer, this relatively short guarantee doesn’t inspire much faith in their longevity. 😞

If you want a mattress you know will last, we suggest looking for one with at least a 10-year guarantee.

If you want a truly luxurious feeling and long-lasting mattress, it may be worth shopping with a brand that offers longer, reliable guarantees.
The industry standard for mattress warranties is 10 years, but you can find mattresses that are protected for even longer!

One brand that goes above and beyond when it comes to warranties is Nectar Sleep, which is so confident about its mattress longevity that it offers customers a lifetime guarantee.

People who prefer a softer mattress

Sealy mattresses lean towards the firmer side. 🛏️

While they do have a few softer mattresses in the Sealy Posturepedic range, these options are limited.

If you prefer a softer sleeping surface, you may want to look at our article on the best soft mattresses in the UK.

Alternatively, a mattress topper might be the quick fix you need.

Mattress toppers
Mattress toppers can help change the feel of your mattress.

The dual-sided Emma Flip Mattress Topper lets you flip between a softer and firmer side - perfect if you're undecided about your comfort preference. 🔄


Sealy mattress sizes

Sealy offers a variety of sizes to cater to everyone's sleeping needs.

These include:

  • Sealy single mattresses - 90 x 190 cm (3' x 6'3").
  • Sealy small double mattresses - 120 x 190 cm (4' x 6'3").
  • Sealy double mattresses - 135 x 190 cm (4'6" x 6'3").
  • Sealy king-size mattresses - 150 x 200 cm (5’ x 6’6”).
  • Sealy super king mattresses - 180 x 200 cm (6' x 6'6").

Retailers like Mattress Online, Mattress Next Day, and Dreams stock everything from single Sealy Ortho Plus mattresses to Sealy Posturepedic mattress king-size versions.

Just be warned that not all Sealy mattresses come in the small double size.

If you're scratching your head over what size mattress to get, our handy guide on how to choose the right mattress size may help.

Generally, taller adults and couples will want at least a double bed.

UK mattress sizes
Sealy mattresses come in most standard UK sizes, meaning it should be easy to find one that fits your home and needs.

But if you enjoy spreading out and have the space, you may prefer a roomier king-size or super-king mattress from Sealy. 👑


Sealy mattress prices

You can find basic Sealy models for just a few hundred pounds, while premium options can run into the thousands.

Sealy's extensive collection makes it easy to find something that fits your budget. 💷

However, a heads-up: Sealy trials and guarantees are pretty short, particularly considering the high price of some of their mattresses.

You may still find a Sealy mattress is worth it for you, given that the brand partners with orthopaedic specialists, and their mattresses are imbued with this knowledge and the aim to help people sleep better. 👩‍⚕️

People celebrate savings
You can save money if you wait until the next Sealy mattress clearance rolls around to find Sealy beds for sale.

Mattress Online runs regular deals, including Sealy mattress sales, so you shouldn’t have too much trouble finding a bargain.

We’ll always keep our page up-to-date with the latest price reductions, so keep an eye out! 👁️


What else does Sealy sell?

While Sealy is renowned for their mattresses, that's not all they bring to the table.

They also sell bedroom essentials, including:

  • Sealy divan bases
  • Sealy headboards

Currently, Sealy doesn’t sell Sealy mattress toppers, pillows, or other accessories.

Sealy divan bases can be bought with or without drawers.

You can also switch up the look of your Sealy divan with the selection of Sealy headboards. 🛌

Unfortunately, while these items are displayed on the Sealy website, direct purchases aren't possible.

Bensons for Beds is a good bet for those keen on a Sealy headboard or divan bed.

They boast the most impressive range of Sealy beds we’ve seen. 🛍️


Sealy mattress delivery services

It's easy to have a Sealy mattress delivered, though exact delivery options will depend on where you shop.

For free next-day delivery, check out Mattress Online, one of the most popular Sealy retailers in the UK. 🚚

With this service, you can have your Sealy mattress delivered to your front door at no additional cost.

Order and delivery process
Ordering and having your Sealy mattress delivered is easy with sites like Mattress Online.

You may need to pay a little more for a weekend delivery date.

The ‘room of choice’ delivery also costs extra but means your new mattress will be taken straight to your bedroom. 🙂

Just bear in mind that Mattress Online is only insured to carry items up to the third floor, though they can deliver to higher floors if there is a service lift.

You can also have your old mattress removed and recycled for a fee. ♻️


Sealy mattress trials and guarantees

Sealy's mattress trials and guarantees change depending on where you buy your mattress.

If you buy a Sealy mattress from Mattress Online, they offer a 60-night trial.

This trial allows you to try your mattress and swap it out for a different Sealy mattress if you don’t like it. 🔄

Trial period product exchanges
Unfortunately, Mattress Online Sealy trial periods don't allow customers to swap a Sealy mattress for a different brand or return it for a full refund.

On the guarantee front, Sealy is more conservative.

The longest guarantee is 7 years, but many of their mattresses only have a 5-year guarantee. 📅

It's underwhelming, especially considering that many brands offer a 10-year guarantee as standard and brands like Nectar offer a seriously impressive lifetime guarantee.

We’d certainly like to see Sealy improve their mattress guarantees in the future.

Should you buy a Sealy mattress?

The Sealy range offers something for almost every budget.

While Sealy trials and guarantees might not be the industry's longest, their collaboration with orthopaedic experts and commitment to research set them apart. 🛌

So, if you value expert-backed design, Sealy could be perfect for you. 😴

  • How long does a sealy mattress last?

    Sealy claims its mattresses are built for durability

    While a Sealy mattress UK typically comes with a guarantee that ranges between 5 and 7 years, with proper care, it may last longer.

    According to Sealy, their mattresses can last for more than a decade

    However, it’s worth noting that multiple Sealy mattress reviews UK on platforms like Trustpilot have stated that their Sealy mattress began sagging after as little as a year.

    Sagging should be covered under the Sealy guarantee, but some customers have had their claim rejected if the dip was within the few centimetres deemed as normal.

    If your primary concern is to buy a mattress that lasts, you may prefer to check out mattresses from brands with longer (even lifetime) guarantees, such as Nectar or DreamCloud.
