Becky’s take

By Becky Reeve

Checked against current models and prices in October 2026

I'd buy a SleepSoul over any Sealy that isn't latex, and most Sealys aren't. Sealy's biggest sellers are open coil in firm and extra-firm, the Steeple Ortho Plus and the Mellbreak among them. On open coil a turn on one side travels across the whole bed, and the middle sags first. SleepSoul rolls pocket springs into a box with foam on top, and pocket springs beat tied coils at any budget, because each one takes your weight on its own.

Sealy is a huge, bland catalogue and I'd buy something better than most of it. The exceptions are the Newton in firm and the Bronte in medium. Both are latex, bouncy and cool, and latex keeps its bounce for years. If you sleep hot, or you want a bed for the long haul, buy Sealy's latex. Sealy is the dearer brand, with several times as many reviews.

Everyone else should buy SleepSoul's Balance 800 or the firm Space 4000. The Space 4000 has Orthopaedic printed on it too, and on both labels that word means firm and nothing more. Steer clear of SleepSoul's pillow tops and Sealy's open coil.

Head to head

SleepSoul has 10 of its 11 mattresses sprung; Sealy has 20 of its 57 mattresses sprung and 8 all memory foam. Only Sealy offers latex, in 11 models. SleepSoul runs from soft-medium to firm, and Sealy runs from soft-medium to extra firm. SleepSoul is the budget choice of the two: Sealy's cheapest mattress costs several times as much. At the top end Sealy goes further still. Sealy's owner score rests on far more reviews (10,380 against 2,837), so treat SleepSoul's number as the less settled of the two.

SleepSoul

SleepSoul is one of the newest manufacturers to make a splash in the last few years, entering the arena at the start of the first lockdown and rapidly expanding through its use of existing supply chains provided by its parent company, Birlea. Since inception SleepSoul has rapidly gained a strong market position in the bed in the box space, competing directly with other popular manufacturers like Eve, Simba and Nectar.

SleepSoul are not sold directly and are instead sold through a host of retailers up and down the country in both online and offline capacity where the price of these mid-tier priced products tend to get carved up down to the lowest pound as everyone reaches to capture the sale.

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

SleepSoul owner satisfaction

Owners are mostly happy with the SleepSoul range, and the praise is much the same across it: comfort, value and a box that is easy to unpack. One Bliss 800 owner called it “Good quality and excellent for the price”. Another found it “very easy to manage, open and soon plumped up”.

Firmness is the recurring complaint, and it runs both ways on the same model: one Bliss 800 owner wrote that it was “not medium as advertised. It's soft.” Another found the same mattress “Far more firm than the description suggests”. A few owners find them warm at night. The other complaint that keeps coming up is edge support, mostly on the Comfort 800 and Heaven 1000, and a few owners across the range say they can feel the springs. One Comfort 800 owner wrote that “the unsupported edges are annoying”.

SleepSoul supportiveness

Supportiveness is at the forefront of SleepSoul design, with pocket spring support structure taking centre position in the lineup and offering a great variety of tensions ranging from medium to firm in their more popular offerings. The open coil variants perform less well however, do feature at a price point making them a great option for those on a budget,

The support layer in much of the range is able to be compacted and rolled, giving you a tighter package come delivery that saves on logistical and delivery costs that can be passed on to you.

SleepSoul durability

Owner reviews of the range go back years, and those that mention wear are split. One owner bought a second SleepSoul about five years after the first and said the original was “STILL as good and cosy as new”. A small number report a dip or sag forming within the first few months.

To offset this concern, SleepSoul has developed a 10 year warranty to accompany the purchase of mattresses in the range. This warranty should go a considerable way to alleviating the worry over sagging and will help establish SleepSoul as a leader in the industry.

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)

This is a really comfortable, good quality mattress. When it arrived (in an amazingly small box), the mattress was well wrapped up in plastic and there was a little tool to slice the plastic open without slicing the mattress, plus instructions for the mattress. It was simple and straightforward and the mattress was ready to sleep on in just an hour or so. There was no obvious chemical smell, just a slight whiff if I put my nose right on it as soon as it came out of the wrapping. I haven't been bothered by any smell when sleeping on it. I bought it as an urgent need because the old one was giving me back pain. After two nights on this mattress, the pain was gone and i've had a couple of weeks of very comfortable nights with much better sleep so far. The only thing i'm not so pleased with is the edges squish down when you sit on them. I guess they have to in order to fit inside the small box but I prefer the edge of a mattress to keep its shape when I sit on it. It's not a major problem as I sleep alone but if I shared it and had to sleep near the edge, i'd feel as if I was going to roll out of bed. I'd want a king size if I was to share it. I will also get a mattress topper just to increase the comfort factor even more (and to fulfil the conditions of the guarantee). Overall, I am very happy with this mattress, it's great to feel comfortable and well supported. With the discount, it's amazing quality for the price. So glad I bought it; my back thanks me every morning.

Good Points: It's the first new mattress I have had in years and its quite a difference but theres lots I like about the change: - The mattress is very supportive of my body, I'm 5'11 and weigh nearly 100kg's, support matters! - It feels stable and doesn't make me roll to any low spots - The mattress is far lighter than I anticipated so rotation by myself is really easy, especially with the handles - It keeps me warmer which during the late heat was a bit of an issue but I think I'll appreciate it during the winter - It arrived rolled and it was easy to remove and set up in no time Improvement Points: There are a couple of things but these are very minor, and they are just my views: - The handles, despite the low overall mattress weight dont feel very sturdy and I worry I'll rip them clean off - The measurements indicate the mattress depth, and was made very clear on the website, but depite my measurements it was still a shock to see such a deep mattress having been used to very thin one for years - I think I remember seeing it mentioned as being on the firmer side of things but compared to my previous mattress this is much softer (not necessarily a bad thing, just didnt expect it is all) Thats it really. As you can see the negatives for me are very minor and I would overall highly recommend the product.

The product itself is as expected, it was delivered vacuum packed in a box as tall as the mattress is wide and rolled up, so it doesn't take up too much space and is just small enough for the average male to handle. It is of cause a bit on the heavy side so probably be a good idea to get help if moving up stairs but is easy enough to slide up the stairs on its side. The box contains the mattress along with a handy safety knife to open the vacuum sealed bag and some documents. After removing the mattress from the box take care with the unrolling as it is a bit weighty and king of suddenly springs/flops the last 2 or 3 foot so have no breakables near the end if unrolling on the bead frame. When cutting the plastic try not to cut a large hole, doing this will allow the air to gradually enter the mattress and the mattress will safely spring back to it intended shape, then you can remove the plastic with the provided safety knife. The mattress boasts a 1000 pocket springs topped with memory foam so no need for a mattress topper as there's plenty of padding on top of the springs. I found the medium firmness of the mattress to be just right for me and after having the mattress for a month now I can confirm that I sleep better. The price was very competitive the quality it right for the price but the delivery let down experience a bit, the guy was unbelievably miserable didn't say a word to me, didn't smile (giving off couldn't care any less vibes) attitude was disgusting.

Improvement Points: I ordered the 120cm wide 'small double' mattress. Once unwrapped, it was clearly far too wide and would not fit on my bed frame, being around 125 cm wide. I know that foam mattresses take a while to regain their proper shape, however this has not been as quick as anticipated. As a the spare bed mattress, it has slowly change shape, and after about 4 weeks of resting and not being slept on, it is now about 122cm wide. It just about fits onto the frame.

1 Trusted Customer

Good Points: In the first year or so resonably comfortable but then it goes wrong... Improvement Points: After about 2 years the mattress has developed 2 distinct dips, about 3cm deep (after ~4 hours after getting about of bed. They are worse first thing) so at night you keep rolling back into them. I'm told : 'Over a period of time the body will create a natural impression on the mattress. This is known as settlement and is perfectly normal.' I dont beleive a dip that is deep enough to affect your sleeping position is normal and i didn't have this in a previous memory foam mattress. We only changed as we went up in bed size. So after 2 years use of a mattress that has a 10 year warranty I am having to buy a new one as this is unbearable to sleep on. Spend a bit more and get something better with reviews after a few years, not a few days.

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.
