On aggregated owner reviews the two are level at 4.8 out of 5, so the choice comes down to price, trial and guarantee.

Head to head

Simba has sprung throughout, with pocket springs or a hybrid build in every model; Dunlopillo has 5 of its 9 mattresses sprung. Simba runs from medium to medium-firm, and Dunlopillo runs from soft-medium to firm. Dunlopillo covers more of the firmness scale, which helps if two sleepers need different feels. Simba is clearly the cheaper way in; Dunlopillo's range starts well above it. Simba's owner score rests on far more reviews (12,329 against 85), so treat Dunlopillo's number as the less settled of the two.

Simba

Simba have been in the bed-in-a-box industry since 2015. Simba started its journey with one mattress before branching out to encompass an entire range. These aren’t just any mattresses though, and they have been tested using data from ten million sleepers’ body profiles and over 100 prototypes to help ensure that the mattress and its design will suit the vast majority of sleepers. To date the Simba lineup has become one of the most well-reviewed mattresses worldwide and with the new line-up, there's different models to suit different budgets.

Simba has an entire lineup dedicated to bed in box rolled mattresses. This avenue to market has become increasingly popular in recent years and has numerous benefits, namely that the cost of the product is typically lower due to savings within logistics warehousing and delivery.

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.

Simba owner satisfaction

Satisfaction for Simba is high on their priority list, offering an impressive comfort guarantee which means that if you are not 100% satisfied with your purchase you are able to organise a return for a full refund. The return process is one of the easiest we have come across and involves letting the company know and they will arrange collection at a time convenient to you. Additionally, there are no additional surcharges, costs or delivery fees associated with the returns process which means you get 200 nights risk free to try the mattress.

After this trial period you will also receive a 10 year guarantee that will further instil confidence and ensure your investment is protected long term.

Simba supportiveness

Simba have multiple mattresses in their range, however all offer roughly the same level of supportiveness coming in at a medium firm tension. The comfort that you derive from a mattress will generally come from the top layer that sits somewhat detached from the support layer. The support layer is what contours and fights against your body to give you pressure relief. Depending on how you sleep or how much you weigh are both factors in determining suitability of tension. With the medium firm support of the Simba lineup we find them most suitable for back sleepers and those of average or heavier build. That said, due to the inclusivity that Simba has aimed to achieve through its prototypes and extensive testing, we do have plenty of reports of side sleepers and those who are lighter getting maximum comfort out of the lineup.

Simba durability

People are increasingly expecting more from their mattresses with more comfort and more support on offer than ever before. It’s actually a really great time to buy a new mattress as companies new and old are changing the way they do business and produce mattresses with improvements and savings along the way. The same has become true for durability and while the average lifespan of a mattress before being replaced currently lies at around 7 years, the Simba goes above and beyond with a guarantee covering a full 10 years. The result of mattresses lasting longer is the cost of sleep actually decreases relative to cost and time meaning products like Simba may be cheaper in the long run due to that enhanced and increased durability.

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 Simba mattresses

5 Anna B.

We've been needing a new mattress for a long time, to replace our turn of the century Sealy memory foam mattress and divan bed, which we have had lots of use from (2nd hand from family when we got it). We wanted to invest in a really high quality, low environmental impact mattress (and bed) that also ticked all the boxes for comfort, support, no nasty off-gassing chemicals, made with natural materials and market leading durability. This was a huge outlay for us and we've been thinking about it for a few years. We're now in our mid 50's and know that a good night's sleep is crucial, particularly as I'm a light sleeper and have suffered from back and hip pain in the past. Our old mattress was smelly, well past its prime and I dread to think what might have been living in it (and on us!). So, we see this new Simba mattress as an investment for our future. Lots of really helpful info on the website and very enticing video of the mattress we were considering. Once we decided to go for it, we had a bit of trouble paying for the order on the website as I couldn't figure out how to set up the credit facility to spread the cost. In the end I had to message Simba about it and soon after was given the option of having a callback slot, at a time to suit me, to speak to a person. The customer service chap rang me at the allotted time and was very helpful and polite, who helped us resolve the issue, with the added bonus of a further code to use to get free collection of our old bed and mattress, which saved us £50, that really made us happy. We are very pleased with the promotional offer of free high quality Simba bedding as well (2 pillows, duvet and mattress cover), so felt that although it was a big expense, we were buying the best we could afford and were being treated very well as customers. Following the email confirmation of the order after purchase, a day or two later we received details of the VIP service delivery and the date suggested worked for us. So, within a week of placing the order we would get our new bed and mattress (we live in rural Wales, not that easy to get to). Two gentlemen from the delivery company arrived on time, carefully backed up their van on our narrow driveway, carried in the bed and mattress with care, they were really polite and quietly got on with the job of building the new bed. They would have removed the packaging too, but I asked if we could keep it, no problem at all! They removed our old bed and mattress and so within the hour of their arrival we were all set up with our new bed and mattress. Fab! The mattress is very different to our old memory foam one. It's much deeper, heavier and firmer. I'm a side sleeper, but occasionally sleep on my back. It did take me a few days to get used to the new firmer support, but it does have lovely soft cushioning in the top layer. After a few weeks we are now feeling much more comfortable on it than we did initially. I can feel it does give me much better support, as am not getting back pain from sleeping on it. My husband really loves it. According to our Fitbit watches, which we wear at night, we are generally getting a good quality night's sleep (we just need to get to bed earlier now to make the most of it!). For me, with a very sensitive sense of smell, there is also a slight scent of sheep wool, which was stronger to start with. I actually like this smell, and it reminded me what the mattress contains, natural fibres, not off-gassing of chemical VOCs. But, we do make sure we air the bed each day, which is good sleep hygiene, whatever mattress you're on. The mattress comes with helpful information about how to care for it. It definitely will need two of us to turn it every so often, way too heavy for me on my own. I do find changing the bedclothes harder work, as the mattress is heavy to lift to get the fitted sheet on it, especially at the head end. So bear this in mind if you live on your own and you order King Size! You also need to use extra deep fitted sheets. We hope that it'll remain this comfortable for the next 10 years, reassured by the guarantee and love the fact that the mattress was made only a couple of weeks before we bought it (the label on it states when it was made). Nice to think it's not been sitting very long in a warehouse somewhere before we received it. Lovely to know that its recyclable at end of life too and we're supporting a certified B Corp. Fingers crossed we'll both be still sweetly sleeping on it well into our 60's.

So, two weeks ago, I got a response from the supplier of my previous mattress (Emma) saying that due to some sort of restructure, they wouldn’t be able to deliver a new mattress for weeks. They gave me the option to get a refund, which I took. I needed the mattress by that Sunday at the latest as that’s when my temporary accommodation in the Airbnb that I was staying at came to an end and I needed to sleep at my new less-temporary, but unfurnished accommodation. My previous mattress had been damaged by the water ingress at Coniston House (google it for stories in the Standard and The Slice, Tower Hamlets if you're interested). The ongoing works on my building necessitated the move. Anyway, I found a roughly equivalent mattress sold by Simba, which is UK-based and B Corp certified. It is a bit more expensive, but hey, it was an emergency and they offered to deliver the next day if ordered before 1 p. m. This is when it all went horribly wrong. Simba sent the mattress by DPD and DPD’s tracking showed it was out for delivery. The delivery slot came and went and then the tracking said they were running late. Phoning DPD to find out what was going on, they reassured me that they would deliver it that day, but it appeared from the tracking that it had gone back to the depot. I waited in until 8 p. m. The same thing happened on Friday, the contact centre reassured me that it would be delivered, but tracking I could see showed that it was still at the depot. I eventually got a call back from the depot who said it wasn’t out for delivery after all and wouldn’t be delivered that day (despite what the call centre had said). DPD booked it in for a Saturday delivery. Saturday came, again, the same pattern and no delivery. The DPD contact centre doesn’t seem to have any way to contact people on the ground, and I won’t call it lying, but they make statements (e. g. that they will certainly deliver today) which they clearly don’t have the information to back up. On the Monday, I had an exchange with Simba, who arranged for the delivery with DPD to be cancelled. I had to go to the office on Tuesday (I had already spent several days trapped working from home by DPD), so Simba arranged to send out a replacement with ao. com’s logistics on Wednesday. On Wednesday, Garry from AO called me first thing to say he was delivering that morning, and he called again when he was on the way from his previous job. Delivered direct to my door, no fuss. It seems from other reviews of DPD that mattress delivery and other heavy/bulky items are a recurring problem for DPD. I would give Simba five stars, especially for fixing the mess as promptly as they could. However, it was their choice in the first place to use DPD where there appear to be known issues with their performance. If Simba turn to using AO for all their deliveries, I would give them an unqualified recommendation as the mattress is super comfortable and their customer service is helpful and responsive. Most importantly, over the last week, I've had the best night’s sleep I’ve had in over a year!

Despite Simba resolving delivery issues caused by a very dishonest courier, they were also very quick to treat me as though I was lying about not receiving my £1,800 order. Whilst I understand there will be some apprehension due to other dishonest customers, there was no need for the passive aggressive emails and chat messages I received. As soon as I said I lived within MOD barracks and there was no record of the delivery truck or drivers, they sent out a replacement order immediately without explanation. For the mattress itself, I must say that both my husband and I don’t feel it (or the pillows/duvet/mattress topper!) are worth the high prices. We’ve tried to give it time as they say it takes a while to get used to a new mattress, but I really expected to be wowed by a mattress that costs so much, and I’m just not. There are already significant flat areas where my husband and I sleep, despite rotating as advised, which only happened with our old mattress after around 8 years. The pillows come with extra foam cubes so you can fill them more and thus make them firmer, which is great in theory, but I can feel the bumpiness of the cubes under my face, despite distributing them and shaking the pillows etc. Not to mention the fact that the pillows cost so much and are literally just filled with cubed sponge. The quilt is fine, it’s neither here nor there, the buttons can be felt through your duvet cover in the corners which is mildly annoying but the best part is this retails at £399…! The mattress topper is, again, neither here nor there. We tested the mattress without it for a night and it felt exactly the same, so I’m not sure what it really adds. The only good thing I can state about the mattress is that it’s a great level of firm for us (we prefer a more firm one), but again, the cost is not worth this alone, and I’m fairly certain I’d be able to find another for half the price and that feels the same. Sorry, Simba. I will add that we also purchased two inter mattresses for our kids and these are lovely - kids have commented how much they love their new beds and how comfortable they are, which was really important for us while they’re still young and growing. Perhaps we’d be best returning the Luxe and getting an Inter.

Sadly, I cannot recommend Simba based on my experience. I ordered a mattress advertised as being 25 cm deep. The first mattress I received measured approximately 22 cm. It was only after raising this with Simba that the ±2 cm manufacturing tolerance became particularly relevant. This tolerance is contained within their Terms & Conditions, but in my opinion it is not made sufficiently clear alongside the advertised mattress dimensions when purchasing. A ±2 cm tolerance on a 25 cm mattress is actually quite significant — potentially anywhere between 23 cm and 27 cm — and I think this should be made much more obvious to customers before they buy. Even allowing for that fairly generous tolerance, my first mattress at approximately 22 cm was still outside Simba's own stated specification, so they agreed to replace it. Unfortunately, the replacement mattress measured approximately 22.5 cm — once again outside their own stated tolerance. Despite this, I was then told that the 22.5 cm depth was fine and would not affect the performance of the mattress. This completely misses the point. If a product is prominently advertised as being 25 cm deep, and the manufacturer already allows itself a ±2 cm tolerance, I don't think it's unreasonable to expect the product supplied to at least fall within that range. I specifically needed a 25 cm mattress, which was one of the reasons I chose this particular model in the first place. After receiving two mattresses outside even their own stated tolerance, Simba were unable to guarantee that another replacement would meet the advertised specification. I was therefore left with the only realistic option of returning it for a refund. My experience has left me with very little confidence in the accuracy of Simba's advertised dimensions or their manufacturing quality control. I own foam mattresses from other manufacturers that measure within just a few millimetres of their advertised dimensions. By comparison, receiving two Simba mattresses that were both outside even Simba's own ±2 cm tolerance suggests to me that their manufacturing and quality-control standards are simply not good enough. If a mattress is advertised as 25 cm deep, customers shouldn't have to search through Terms & Conditions to discover that it could actually be several centimetres different — and even then receive a product that falls outside that tolerance.

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.
