On aggregated owner reviews, Simba scores higher: 4.8 against 4.6 out of 5.

Head to head

Simba has 9 of its 10 mattresses sprung; Harrison Spinks has sprung throughout, with pocket springs or a hybrid build in every model. Only Simba offers latex, in 1 model. Simba runs from medium to medium-firm, and Harrison Spinks runs from soft to firm. Harrison Spinks covers more of the firmness scale, which helps if two sleepers need different feels. Simba is the cheaper way in, though not by much. But at the top end Simba goes further, so it also has the more premium options. Simba's owner score rests on far more reviews (12,329 against 237), so treat Harrison Spinks's number as the less settled of the two.

Simba

Simba have been around for a long time originally founding in 1979, however, they have only been in the bed-in-a-box industry a few years at this point. 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.

Harrison Spinks

Harrison Spinks is a generational family business that has captured the spirit of the entire hand-made portion of the industry thanks to their traditional materials and handcrafting excellence. The range is of a much higher quality than many competing brands and as a result the price point is typically found within the higher-end but the result is a bespoke nights sleep that will ooze excellence.

Feedback initially looks like the standard lead time has returned across much of the lineup with the majority of the range made-to-order and on 6 week delivery schedules.

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 market leading 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.

Harrison Spinks owner satisfaction

Owners are mostly very happy with this brand which is quite impressive given the price point. Typically we find that when the price of mattresses starts to lead toward the high-end, customers' expectations can sometimes be distorted which results in a less-favourable experience. Thankfully that is mostly not the case here. Owners who bring up the price more often accept it than not, "A bit pricey but the quality reflects the price" as one wrote, though a few didn't think it was worth it, one calling theirs "nothing special for the price I paid". The natural fillings are a reason several give for buying. They can smell at first. That faded within days or weeks for some, but one owner said theirs "smells like a barn". Back pain gets mentioned both ways, with more owners saying theirs has eased than saying the mattress left them aching.

Harrison Spinks supportiveness

The support materials utilised in all Harrison Spinks products is a reliable pocket spring base layer. Pocket springs continue to be the best option for support, offering measured and reliable body contouring across the entire mattress and featuring edge to edge even support and roll together prevention.

Firmness within the range varies but has a pivot toward medium and medium firm tension mattresses all of which are made from luxurious materials and hand made in the UK. Interestingly, Harrison Spinks is the partner of choice for many of the sub-brands sold throughout the popular retailer. The result of this is a Flaxby & Feather and Black sub-division of quality mattresses that will be of equal interest to those looking for a good quality and highly rewarding nights sleep.

Harrison Spinks durability

I think the most important stat when it comes to durability is around the warranty and guarantee periods. After all, if the manufacturer doesn’t believe in their product, why would you? Thankfully you get a 5 year guarantee at minimum across the majority of products on show which comes fairly close to the average replacement period of 7 years for the industry as a whole.

Durability generally doesn’t look to be a concern going by the compounds used. In the reviews, several owners are repeat buyers, one writing “Had a Harrison before and very good for years hence why bought again”, while a small number say theirs softened or dipped within weeks or months.

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.

I have had this mattress for 5 weeks now. When I first unpacked it, there was a slight smell for a day, but since then it hasn't smelt at all. (It smelt of canvas which I found quite pleasant actually!) It feels nice and soft each night when you first get on it, but then can feel it supporting you. I guess this is what is meant by a medium-firm mattress. (My old mattress was over 20 yrs old; if anything it would have been rated as very firm!) I have had no problem sleeping with this mattress, no aches or pains when waking up. It is recommended to rotate the mattress once per week for 12 weeks, so I am still doing that. It is easy to do using the handles on the side of the mattress. No depressions in the mattress have appeared, and it still feels just like new. Although we have already had both hot nights and cold ones, I have never felt too hot or cold due to the mattress (obviously the duvet used is also going to make a difference). Overall I am extremely satisfied with the mattress, and with mattressonline.

To be perfectly honest, I'm not convinced but I think the problem is me, not the product. The mattress is clearly very good quality, but it's a lot firmer than I was hoping for and expecting from the soft/medium description. On the spare bed, which is a fully sprung base, it works reasonably well, which is why I haven't yet engaged the 60 day return option, but on the bed I ordered it for originally, which is a solid Ottoman base, it is way too hard. I'm sure that with use it will soften up, but it's still way too hard for me personally to sleep on comfortably and I doubt it will ever be that soft. Indeed, in desperation I ended up going to a shop and buying a much cheaper (and far inferior quality), softer mattress because I simply couldn't do 30 days sleeping on that mattress. I am going to contact Mattress Online today and enquire about swapping it for something softer.

4 Dave

Good Points: Quality is obvious. If we hadn't had a tempur for over ten years, I would say this is a really comfy bed and would be happy for its life time use. Albeit, only five years gauranteed! Having had a tempur though, I would probably revert back. Mainly due to spouse requiring that extra softness and a complete awareness removal from any turn/roll movement by partner. While this is a fantastic make and constructed with the Best Materials, we have been served well with the tempur and too be honest, can say, there aren't any regrets with the purchase. Improvement Points: Comparing this to our tempur, it would be difficult to separate, based on the very different structures. That said, a longer guarantee period would be an advantage. Price for price - this would be a distinct advantage.

We tried the mattress in the shop and picked it over the medium/firm version. However when the mattress was delivered it was so firm it caused my partner hip pain. We contacted mattress inline via the 60 day sleep guarantee and they swapped it next day. The service was 5* and reason we buy all our mattresses via them. The new mattress is the medium firm and is super comfy even after the first night. Makes me think the first was faulty it was that hard and nothing like the shop one we tried.

1 Nigel K

The mattress smells like a farmyard, not natural, and has made our bedding smell as well as the bedroom. This is not the natural smell the company claims, there is something wrong with the mattress. We cannot have the mattress removed from our home or changed for another month as the company wants to send somebody to check the mattress, but they cannot visit us for the next four weeks. Do not ever buy a mattress from Harrison Spinks unless you enjoy your bedroom and bed linen smelling like you are sleeping in a barn on a farm.
