How we test products
Our mission is to take the guesswork out of finding the perfect sleep products.
We've dedicated hundreds of hours to testing mattresses and sleep accessories, and rely on a team of testers of differing weights, temperature preferences, and sleeping positions to evaluate each product.
Tested products are granted the Sleep Hero tested stamp of approval, a mark of our review's reliability.
If we haven't personally tested a product, please be assured that we invest significant time and energy into scouring the UK market and researching the best recommendations, and we work with a team of sleep experts who review our articles, ensuring that the insights we provide are not only relatable but also reliable.
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.
Sealy has continued to grow over the years, placing increasing importance on enhancing its products.
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 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. 👇
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.
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.
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.
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.
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.
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 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.
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.
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 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. 👩⚕️
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! 👁️
Sealy mattress delivery services
It's easy to have a Sealy mattress delivered, though exact delivery options will depend on where you shop.

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