Overall score4.7/5

On aggregated owner reviews the two are level at 4.7 out of 5, so the choice comes down to price, trial and guarantee.

Head to head

Tempur has all foam, with no springs anywhere in the range; Sealy has 20 of its 54 mattresses sprung and 8 all memory foam. Only Sealy offers latex, in 10 models. Tempur runs from soft to firm, and Sealy runs from soft-medium to extra firm. Sealy is clearly the cheaper way in; Tempur's range starts well above it. But at the top end Sealy goes further, so it also has the more premium options. Sealy's owner score rests on far more reviews (10,081 against 3,039), so treat Tempur's number as the less settled of the two.

Tempur

Tempur was first born in the 1980’s to relatively lukewarm acclaim, see, it was the memory foam that really got Tempur finding it’s stride and this didn’t happen until 1991, becoming one of the first companies in the world to see the commercial benefits of what is now known today as memory foam.

Today Tempur is one of the largest mattress companies in the UK and serves thousands of customers yearly with its high quality no-compromise foam filled mattresses. The Tempur brand carries huge weight and is available in many bedding and chain retailers throughout. The standout features of Tempur have kept owners coming back for decades, and those replacing one often say the old mattress lasted far beyond the traditional 7-year buying cycle. One wrote that “my last Tempur mattress lasted nearly 20 years”. A few report a new one going soft or sagging within months.

With competitive pricing and unique memory foam bounce-back comfort, it’s not hard to see why Tempur are leading the way some 40 years after inception.

Sealy

Sealy has formerly separated from Silentnight, who once managed the UK arm of the popular retailer and will now be re-acquired by Tempur Sealy International. For those who don’t know, Sealy is the world's biggest bed brand that’s not down to luck, Sealy mattresses are highly regarded and at a price point that is achievable for the vast majority of people. What’s more, the company produces handmade beds right here in the UK using some of the finest fillings and upholstery.

Sealy’s Posturepedic technology makes it ideal for those with back and neck pain looking for that additional bit of support, becoming the only partner to be approved under the Orthopaedic Advisory Board

Tempur owner satisfaction

Tempur owner satisfaction is one of the main reasons why people go on to buy another Tempur when the time eventually comes to replace. See, Tempur mattresses are almost seen as part of a ‘cult’, once you’ve slept on one, the idea of moving to an alternate brand no longer makes sense. Reviews for Tempur mattresses mostly talk of comfort and a better night’s sleep, and owners with a bad back often say the aches have eased. A minority regret it. Some wake with aches they didn’t have before, some find theirs too firm or too warm, and one called it “the most uncomfortable mattress we have ever slept on”.

Price points may serve as an issue for those looking for something a little cheaper, however, the reputation for improving the quality of people’s sleep cannot be overstated.

Tempur supportiveness

When it comes to supportiveness you could be forgiven for looking beyond Tempur mattresses. After all, the memory foam comfort layer that is unique to Tempur is, as the name suggests, for comfort and not reflective of the support systems on offer. Fortunately Tempur mattresses now feature TEMPUR® Support Material for an outstanding support layer that is unique to the brand and not available on competing products. What’s more, the company has created a small but pointed range of mattresses to ensure that whatever your support preference of soft, medium or firm, there is something for everyone.

My personal preference continues to be the medium firmness tension which offers enough support with enough “give” to ensure you will sink deep into the mattress which makes it ideal for the average person sleeping on their side.

Tempur durability

Different Tempur products have different guarantees but I do think it is particularly telling of the Tempur durability that their mattress lineup will most frequently come with a 10 year guarantee. This guarantee is a testament to the confidence the manufacturer has in their products. After all, each Tempur mattress takes around 60 hours to make (according to Tempur themselves), and in that time they go through up to 67 different quality and assurance tests to ensure that you get the right product that is built to last.

So much of the competition features 1 year guarantees which make it harder to justify the case that their durability is of a primary concern.

Sealy owner satisfaction

Satisfaction is at the heart of what Sealy offers. Since their inception Sealy has offered numerous different base and comfort layers to try and appease all areas of the market. The company has largely remained successful in their plight thanks to their strong support within the mid-tier market. Owners are mostly happy with what they bought, and comfort is the thing they mention most often. Back pain easing comes up as well, with one owner writing "my backache has virtually disappeared now". The complaints are far fewer, and firmness is the main one: some owners found theirs harder than expected and a smaller number softer, with one calling it "Harder than the model we tried in the shop". Dips forming where people sleep are the other complaint that recurs.

Sealy supportiveness

The Sealy lineup includes everything from soft through to firm tensions. The most popular in the range are the mediums which give the best overall support for most people, pairing well with the pocket spring support layer to offer full body contouring for all-round support without feeling too-firm.

For those looking for a bit more support, Sealy has firmness grades exceeding firm and entering extra-firm territory. We would personally recommend these only for specific circumstances as comfort is reduced slightly to better aid support.

Sealy durability

When it comes to durability Sealy performs in line with expectation. We do see a bit of fallout from some of the cheaper in the range, particularly the open coil sprung models which, combined with a single sided comfort layer often do not have long-lasting properties and may not afford as good value as initially perceived due to their reduced operating lifespan. Contrary to this is the excellent pocket sprung options on offer from Sealy, particularly when paired with a double sided comfort layer. A combination of these will ensure you get a long standing mattress that will last far better and in-line with the average expectancy where people typically look at replacing their mattress (7 years)

I’ve been sleeping on the Tempur Pro Air SmartCool Plus medium-firm 25cm mattress for a while now, and it has genuinely transformed my sleep quality. The first thing I noticed was how supportive it feels—it has that classic Tempur contouring, but with a more modern, responsive feel that doesn’t leave you “sinking” too much. The medium-firm level strikes a perfect balance: soft enough to relieve pressure on my shoulders and hips, but firm enough to keep my spine aligned. The SmartCool cover is a standout feature. It has a noticeably cool touch from the moment you lie down, and it actually maintains that effect throughout the night. I tend to overheat, but this mattress has made a real difference—no more waking up warm or needing to flip the covers off. Motion isolation is excellent too. Whether someone gets in, gets out, or turns over, the movement barely carries, which is ideal for light sleepers. The 25cm height feels substantial and premium without being overly bulky, and the build quality is exactly what you’d expect from Tempur—solid, well-crafted, and luxurious. Overall: A fantastic upgrade if you want pressure relief, cooling, and high-end comfort in one mattress. It’s definitely an investment, but one that pays off every single night.

4 Disabled and unhappy

Hi I have an adjustable bed. brought my last Tempur mattress designed for adjustable beds about 8 years ago. I was sleeping less than an hour a night for 18 months and even scared to go to bed due to chronic pain. Being disabled you get VAT relief on items to help with your condition. When I purchased my first Tempur mattress I got VAT taken off when I purchased it. Due to not being able to sleep flat from 4 major spine and spinal cord surgeries all leaving me in more pain and worse off from surgery. We could not afford a new Tempur mattress really the only silver lining was we would get the VAT taken off went to same store, we live in same home. Staff said they don’t do it when you purchase in store anymore and it would be down by customer services. I gave them evidence and they sent that off when we brought the new mattress that is specifically designed for adjustable beds. I phoned after delivery to check about how much the payments would be with the VAT removed. But was very unhelpful and said it was a luxury purchase and not due VAT off. I explained that we confirmed before we brought it with the guys in the shop and they said it would be deducted through customer services. The mattress has work wonders and I’m now getting 3 hours sleep a night. Which is nearly four fold. The woman I spoke to probably 2 wks ago said a manager whom could deal with this was going to phone me at some point but still haven’t heard anything. We did everything right to ask and check.

Bought this mattress from Dreams almost one year ago. As with every new thing, you’re excited and see only the good parts, in this case, how confy the mattress is, how you don't feel when your partner moves, etc. But there's something really wrong with this mattress and this is not only my opinion, my wife strongly agrees with me. As long as you are alone in bed, Yes, it's amazing, you are floating, no pressure points, great sleep. But, and this is a big BUT: The mattress slowly sinks under your weight, taking the shape of your body ????. But what happens when two bodies are next to each other? The mattress obviously sinks, obviously in the middle of the bed, creating a massive "valley" and your bodies will be dragged at the bottom of that valley. You'll wake up in the night, like sitting in a hammock, glued to your partner. The sides of mattress are staying high and firm and the centre of the mattress will be at it's lowest. You will climb towards the side, trying to get out from the valley, and you'll find yourself back in again and again. You might think we are heavy people! Yeah right, I'm 72Kg and 1.87m that something like 11 stones and just over 6ft, and my Mrs is 62Kg, so I don't think we are overwhelming the mattress in any way. If you sleep alone in your bed, Yes, best thing the money can buy. If you are a couple, big NO! We've bought the tallest one, paid a lot of money, and not even one year later we are 100% it has to go, reason why I've decided to leave this review. Best of luck.

It does support most of your body rather well overall but if you are a man with wider shoulders you will wake up with shoulder and pain in your ribs without getting a good night's sleep. After spending a lot of money to upgrade to this bed I am left very disappointed as I have done nothing but toss and turn all night in discomfort. I will probably have to try and find a zoned mattress topper to cushion my shoulders which are like hen's teeth in the UK. For the sheer price of this mattress I would have thought the comfort layers would have been slightly thicker and I am a bit annoyed I will have to shop for more items to get a good night's sleep on it. We were sold this mattress believing that it would reduce pressure points but it's barely done that and compared to the old one and has put a lot of pressure on my spine and rib cage. This was after using the sleep match feature in-store so I am really hoping this mattress softens up a bit here in the problem areas. The whole gimmick about it being having cooling features is complete nonsense too, If anything it's a lot warmer than any bed I have had previously, but I sleep with a fan on so that's not the end of the world. Overall not all that impressed considering the price of it, considering I had to take finance out to pay for it too. If these mattresses had zoned support they would be top notch but I don't think they are built for men with wider shoulders.

I’ve been sleeping on this mattress for a few nights now and I’m pleased to say it’s making a positive difference. I was hoping for something supportive and comfortable, and this mattress delivers on both fronts. What I like The medium-firm feel hits a nice balance: not so hard that you feel like you’re lying on a plank, yet firm enough to feel properly supported. The product’s description calls it “medium-firm” and highlights the balance between support and plushness. The cooling feature is visible: the mattress uses INFUSE™ Black Diamond Graphite foam (which I must admit sounded fancy to me) to help with temperature regulation. According to the spec it “keeps you cool while cushioning your hips and back”. On warmer nights I’ve noticed I’m less restless. Excellent support for back and hips: I wake up without the usual niggles around the lower back and shoulders that I used to get with older mattresses. The “AlignSupport® coils” and plant-based ComfortCore layer appear to be doing their job. Good edge support: the mattress doesn’t feel as though you’ll roll off when you get close to the edge, and the usable surface feels generous. That’s helpful when two of us are sharing it. Quality and build: the cover feels robust, the stitching seems neat, and while I won’t pretend to have dismantled it, it gives a sense of quality rather than a bargain compromise. Where there’s room for improvement (or things to know) It’s a bit heavier/setup-intensive than my old one: rotating or manoeuvring it takes a bit of effort. If you prefer a super soft, sinking-in feel (the “body-hug” kind) this mattress might feel a little firm. Some reviews of the same family of mattresses note that side-sleepers (especially lightweight ones) might find medium-firm less contouring than they’d like. As with many new mattresses, there was a short adjustment period for my body clock and sleep-muscles to adapt. The first two nights felt slightly unfamiliar; by night three I was into it. Cooling is better than my previous mattress, but if you’re a very hot sleeper I wouldn’t say it’s magic. The spec claims better temperature control but some users of related models still noted some heat retention. Verdict In my view this is a strong pick if you want a mattress that blends support with comfort, especially if you’ve got a back that lets you know when the mattress is doing a poor job. For someone like me (part-time mystic, allotment keeper, old bones) it feels like a good investment in sleep rather than just a piece of furniture. I’d say I’m waking up more rested, and that alone makes the change worthwhile.

Lying on a bed in a shop fully clothed for a few minutes is one thing. Lying on it for 8 hours in thin nightwear is something else. I tried the Newton bed in the shop and it seemed comfortable, although it may have been there years and hundreds of customers may have bounced on it. Once delivered (and Bensons were totally professional in that regard) I got backache after one night. Others have remarked their bed seemed firmer than in the shop. Dreams sell the same mattress but they call it Hagen and rate it very firm which it certainly is. I found I could get my hands behind the small of my back and exactly the same when I lay on the floor !! I also got cubital tunnel syndrome (hard bed pressed on shoulder and elbow causing pain down arm and little finger went numb !) A topper improved things a bit but if you need a topper to make your bed comfy you're probably lying on the wrong bed ! After a week of pain I decided to switch to a medium Newton which you wouldn't know existed if you only went in the store and didn't look online. I zoom called Bensons HQ who confirmed none of their shops displayed it. So why didn't I order a medium in the first place ? I didn't like the idea of buying a bed I hadn't tried first (if that is any guide) but in the end I was forced to ! Now medium doesn't mean soft. It just means slightly less firm !! I phoned Sealy HQ who explained the only difference is Newton Medium has firm and medium foam, not extra firm foam like their firm version. I'd give Newton firm a 9/10 rating for firmness and Newton Medium 7/10 although that may ease to a 6 in a few months. Incidentally I did consider the Bronte too. I had a pillow top but found it got frayed and torn after 6 years (I'm a restless sleeper), was heavier to turn, higher and the sheets didn't fit. As others have mentioned I found it warm to lie on after just 10 minutes so wondered how hot it would be after 8 hours. To be brutally honest I didn't think it worth an extra £400 which is a lot for a pensioner ! If you want a soft top buy a mattress topper for the Newton Medium and save yourself the extra expense. A final point, I found the Newton Medium somewhat lighter than the firm, probably due to the lack of hard heavy-duty foam.

Absolutely horrible. This is a completely unbiased review after owning it for almost 4 months now, and rotating it around as per instructions. After trying out a few beds in various stores and doing some research into the kind of bed I wanted in an Extra Firm, this was one was the best *when I tried laying down on it in store*. However, when I received this, it felt like a completely different mattress - soft, pudgy, sinks down in the middle (what Central zoning PowerPack/lumbar support technology? Is this a scam?) and downright uncomfortable. I got this to help with a back injury I suffered a while back, so that means solid support that keeps that back held up firm, but this was the opposite, and the softness of it actually caused me more pain and discomfort in the long run. EdgeGuard - newsflash: it has no EdgeGuard support or technology in it. You roll off the edge just like on a standard mattress. Extra Firm rating: Nothing more than a lie. There is nothing about this that could classify it as extra firm. Other than its bad quality, the firmness rating would be medium to firm. Definitely not Extra Firm, and it was definitely not the same mattress I tried in store. The only positives were the delivery crew were amazing. Top lads. I really regret not going with my initial option from mattressonline, which had the same specs and was cheaper too. I would not even pay £200 for this rubbish.

In the store this was the most comfortable mattress. We tried nearly every mattress in the shop. The selling point was the construction of the mattress and the salespersons insistence this was one of the most popular and highly rated mattress in the U.K. We bought the mattress and the delivery was arranged. First class service. Once the mattress has been delivered and the packaging removed, the smell was overpowering in the room. This was described to us as the mattress "off gassing" and the smell would dissipate within 48 hours. Luckily we have extra bedroom so it was left to vent its gasses. Two weeks later I decided to make up the bed even though the "off gassing" was still there.We have slept in it once, my wife who suffers from asthma now sleeps in the spare room. She awoke in the night in a coughing fit. I am trying to use the bed myself but I wake up with this smell wafting from the bed. This smell was not evident in the showroom. The current advice is to place it in the garage to air properly. I am so angry about this mattress. It's a shame because we have used bensonforbeds regularly and never had any issue before. This mattress will be withdrawn from sale if they want loyal custom.
