Becky’s take

By Becky Reeve

Checked against current models and prices in October 2026

If you've settled on latex, buy the Dunlopillo. Both brands sell it, and that is the only question here. Every Dunlopillo we list is latex, medium to firm and expensive. The Latex Superior models have a solid latex core, and the Meya, the Kareena and the Elite Luxury put latex over pocket springs. Sealy's latex is a layer on top of a sprung base, on the Newton, the Bronte and the PostureLux models.

So decide how much latex you want under you. A whole core gives you the most of it. It gives under your hip, pushes straight back when you turn, lets heat out and keeps doing so for years. That's the Dunlopillo. A latex layer over springs gets you most of that feel, and that's the Sealy, which has been bought and reviewed far more often than every Dunlopillo put together.

Sealy's best sellers, the Mellbreak Ortho Plus, the Steeple Ortho Plus and the Alford Advantage, are open coil, a far cheaper build, so ignore them. I'm a Dunlopillo convert. A Dunlopillo pillow has been mine for years and I've never wanted to replace it.

Head to head

Sealy has 20 of its 61 mattresses sprung and 8 all memory foam; Dunlopillo has 5 of its 9 mattresses sprung. Sealy runs from soft-medium to extra firm, and Dunlopillo runs from soft-medium to firm. Sealy is clearly the cheaper way in; Dunlopillo's range starts well above it. Sealy's owner score rests on far more reviews (10,172 against 85), so treat Dunlopillo's number as the less settled of the two.

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

Dunlopillo

Dunlopillo have been in the mattress “game” for nearly a century, dating back to 1929 when a scientist created what we know today as Dunlopillo Latex. The latex would form the backbone of all future mattresses and a staple of the industry as a whole.

The company has since gone under new ownership and sees itself as part of the Relyon group where it enjoys an enviable position as one of the market leaders in latex mattresses around the UK and worldwide. If you are looking for a mattress that possesses many of the qualities of memory foam without the downsides of heat build up, latex could be for you.

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-medium 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)

Dunlopillo owner satisfaction

Owner satisfaction is high across the lineup. The striking thing in the reviews is the repeat buyers, owners replacing a Dunlopillo they had slept on for 16 or 20 years with the same again. Comfort and support draw most of the praise, and the complaint that comes up most is the lack of turning handles, with the weight and the price behind it. This does create a minor inconvenience when it comes to rotations but does help highlight just how impressive the lineup is when the largest vocal problem is around handles.

When you consider the life expectancy of a Dunlopillo mattress on average and look at the cost per night of sleep as a result, the entire range makes for incredible value for money.

Dunlopillo supportiveness

Owners are largely happy with the support, and “very supportive and comfortable” is about the typical verdict. Featuring a wide array of tensions from soft through to firm it means that there is always a Dunlopillo mattress suitable for you, regardless of body type and sleeping preference. The tension and supportiveness of these mattresses is offset by the top layer of the product being latex, which will offer a degree of softness and comfort within the upper layer of the mattress, helping to create a unique experience with the support layer below.

Dunlopillo mattresses also feature an impressive amount of edge support which allows you to make full use of the product. Many cheaper brands do not have this feature which means you do not have the confidence while sleeping close to the edge of the mattress where it feels like it would otherwise be “giving way”

Dunlopillo durability

As mentioned within customer satisfaction, owners talk about Dunlopillo mattresses that lasted them the best part of 20 years before they bought the same again. That alone tells you all you need to know about durability. Handcrafted within the UK and featuring hypoallergenic materials with a rugged yet soft cover, these mattresses are durable and well reviewed.

Dunlopillo mattresses tend to be a little more expensive than competing products but the latex upper layer brings a unique feature that many other brands have failed to emulate. Personally, we find the latex to be long lasting and have many benefits over competing memory foam products.

Owner reviews of Sealy mattresses

5 T Phillips

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.

Owner reviews of Dunlopillo mattresses

5 Trusted Customer

Good Points: For someone with a weak back and a tendency for sore joints this provides a good balance between back support and comfort. It is soft to the touch but supports well when you lie down. It needs a slatted base for ventilation. Improvement Points: It is heavy and has no handles, so it is difficult to carry. Our old Dunlopillo mattress had a proper upholstered cover with handles. Even with the best discount it is expensive.

5 Jess H

Love this mattress. It gives plenty of support and we don't disturb each other moving. We have a tripod cat and even she's comfortable walking on it and she is extremely wary of surfaces that aren't stable so that's a definite seal of approval. I have no back pain anymore and actually want to spend time in bed just watching T.V or reading whereas before I could not stay in bed at all without my back killing me. Very happy.

5 Trusted Customer

Good Points: Love my new mattress, tried several Dunlopillo mattresses in shops and like the gentle support of this one. For me it offers the support with out being too hard. Tries a few orthopaedic mattresses and just found them uncomfortable. It's a bit more than I planned to spend but have no regrets. Decided to buy online as it was in stock so received next day and they took my old one away which was a God send.

2 Trusted Customer

Good Points: Looks good. Improvement Points: Far too firm and gives off strange odour. Gave it three weeks then bought a mattress topper. If I could I'd change it.

2 Gaynor L

Not happy, only had it a few weeks and its already sagging , its supposed to be a firm mattress, very dissapointed.
