Relyon

Relyon is the other Royal Warrant holder in the British mattress market, alongside Sleepeezee, and has been making beds in Wellington, Somerset since 1858. That gives it the longest continuous trading history of any mattress brand in the UK, and the company still operates from the same Somerset site today.

Relyon specialises in traditional pocket sprung mattresses with natural fillings, and the range is built around wool, cashmere, silk and horsehair used in different combinations depending on the model. The brand is sold through bed specialists and department stores rather than online direct, which puts it in a different category to the bed in a box brands but also means the quality control is tied to a factory that has been doing this for over a century and a half.

Coolflex

Coolflex is a value hybrid mattress range sold exclusively through MattressNextDay. The brand has grown from a single rolled mattress into a catalogue covering multiple construction types with a specific focus on cooling technology at accessible pricing. The range includes the Essentials Pocket Memory Hybrid, Premium Memory Hybrid, Hybrid Ice, Hybrid Chill and Lux Ortho Pocket, each targeting a different buyer profile.

What makes Coolflex worth looking at is the combination of proper pocket spring hybrid construction with cooling-focused materials at prices that undercut the major direct-to-consumer brands. For hot sleepers shopping on a budget, Coolflex is one of the first alternatives to consider.

Relyon Owner Satisfaction

Relyon scores strongly in owner reviews, averaging around 4.5 to 4.7 out of 5 depending on the model, with the Heritage and Aurora ranges leading the pack. The buyers who rate Relyon highest are the ones who know what they want from a traditional mattress: firm support, natural breathable fillings and the kind of long term value that only comes from a properly built bed.

The most common positive comment is about how the mattress feels the same in year three as it did in month one, which is the best possible advertisement for a mattress brand. On the flip side, Relyon is not the brand to pick if you want that slow sinking memory foam feel, because the range is almost entirely pocket sprung.

Relyon Supportiveness

Relyon's support comes from its pocket spring units, and spring counts in the main ranges start around 1,000 and go up to 2,200 in the higher end models. Above the springs, the natural fillings are layered by hand, tufted into place and finished with a damask cover that lets air move through the mattress rather than trapping body heat.

For back and stomach sleepers, the firmer models give the solid support that helps the lower back stay in line with the shoulders. Side sleepers will want to look at the softer and medium options, which use more generous layers of wool and cashmere on top to cushion the hip and shoulder. Because the mattresses are hand finished, the support is noticeably consistent across the whole surface, with no weak edges or sagging middle.

Relyon Durability

A Relyon mattress is built to last, and the brand has the Royal Warrant and a hundred and sixty year trading history to back that claim up. Hand tufting keeps the natural fillings in place instead of letting them shift over time, which is the single biggest factor in how long a traditional mattress stays comfortable.

Owners regularly report getting a decade or more out of a Relyon before they start thinking about replacement, and the underlying spring units are built to outlast the fillings above them. If you are looking for a mattress that works out cheaper per year than a budget model that needs replacing every four or five, Relyon is one of the few brands in the market that can genuinely deliver on that promise.

Coolflex Owner Satisfaction

Coolflex reviews are consistently strong on two specific points: the cooling performance is real rather than marketing decoration, and the value for money at this price tier is hard to beat from the mainstream alternatives. MattressNextDay handles delivery and returns reliably, which gives the buying experience a stable foundation that standalone budget brands often lack.

Hot sleepers are the buyer profile most likely to rate Coolflex highest, because the cooling technology in the Hybrid Ice and Hybrid Chill models delivers a measurable difference from standard foam alternatives. The main complaint pattern we see relates to edge support on the entry-tier models, which improves as you step up through the range.

Coolflex Supportiveness

The pocket spring cores across the Coolflex hybrid range provide genuine structural support that pure foam alternatives at similar prices typically lack. The Premium Memory Hybrid is the sweet spot for most buyers, with a spring count and foam layer depth that handles average weight sleepers across back and side positions comfortably. The Lux Ortho Pocket handles the firmer end for stomach sleepers and back pain sufferers.

The Hybrid Ice and Hybrid Chill add cooling layers on top of the pocket spring base and are the models to look at specifically for hot sleepers who want temperature regulation alongside the hybrid support structure.

Coolflex Durability

The pocket spring and foam hybrid construction that Coolflex uses across the range is the build type we generally expect to last longest at this price tier. Pocket springs provide structural longevity that all-foam alternatives cannot match, and the foam layers above use reasonable densities for the price point. MattressNextDay backing gives the brand a retail infrastructure that supports warranty claims.

As a newer brand, the long-term durability data is limited compared with heritage manufacturers like Silentnight or Sealy, but the construction approach is sound and the early-year review data is consistent with what you would expect from a well-made hybrid at this price.

Many, many, years ago, we purchased a Slumberland mattress and divan from Dreams in Reading and it gave us faultless service throughout. We recently decided to purchase a mattress of similar design, but how things have moved on since our last purchase. We were certainly impressed with our initial purchase from Dreams and that’s why we decided to visit Dreams in Reading again and were greeted by Jenny who was friendly and professional, but not intrusive, (as can be the case in certain sales type situations, experienced in other stores over the years). Jenny understood the situation and was spot on, professionally and friendly and I knew within a few minutes that we were probably going to purchase from her. Once she understood our needs, she explained that Dreams had this in store computer operated bed, which she encouraged us to lay on (after putting a paper sheet on top of the bed, to ensure and maintain cleanliness, (which is so important with the Covid situation) which in a few minutes, gave information as to probably the type of mattress we should be considering as a couple. After further information, we narrowed our decision down to two mattresses and then eventually the one we decided to purchase. We ended up purchasing a Somerton 1200 pocket sprung mattress featuring Dunlopillo latex, which is exclusive to Dreams and which was also an easy, no turn mattress!!! Delivery was quoted as one week and within a two hour window on the said day. It did get delivered on the agreed day i and at the steed arrival time. We were also amazed how professionally the delivery people were and also how helpful they were in keeping us informed as to what time they would arrive etc. Dreams provided a first class service from the moment we walked into the store, right through to the mattress was delivered and the old one removed. Top marks to Dreams and to their staff for a truly pleasant meeting including the delivery team. And now after 3 weeks of using our new mattress, we know we made the right choice. Thank you to Dreams for a very Special and Satisfying Experience.

A bit extreme perhaps but I've waited a full year before posting this review. When we were looking for a mattress, I read lots of reviews from people who were reviewing something they'd only slept on for a couple of days or perhaps weeks and I didn't find these especially helpful. This mattress wasn't our first choice, we'd originally bought a different one that unfortunately turned out to be faulty. As a side note, Dreams were absolutely brilliant over this - after I reported the issues, we had an engineer visit within a couple of days and it was quickly confirmed that our original purchase had been duff. After our initial bad experience, we didn't want to have a straight replacement, so we re-visited our local store (Chester) to have another look at the potential replacements they had on offer. The sales team there were fantastic, we saw the same advisor who'd helped us on our initial visit - we explained the situation so she knew she wasn't going to earn any commission from helping us but she was wonderful, she spent ages with us and really gave us fantastic service - huge thanks to her! So, at last to the point. I wouldn't have considered a soft mattress, if we hadn't been directed to it by the sleep match machine but our initial impression was excellent, the mattress felt sturdy and well made as well as being very comfortable, although not particularly 'soft'. A year on and we are so, so happy with our choice! My husband's back pain has gone, as has my neck and hip pain - I've packed away the knee pillow that I was having to use to reduce the aches I was feeling with our old mattress. After a few weeks, the pillow top did soften up - I'd been a bit nervous about this happening as I didn't really like the idea of a soft mattress but I needn't have worried, every night is like sleeping on a huge, incredibly supportive marshmallow, it's just lovely. I've never slept better and I wholeheartedly recommend the Highbridge.

My previous mattress was well well well over the recommended used by date, I have been saving to buy a new one for a while. So getting it right was so important- this mattress is perfect, I used the in store sleepmatch or “magic bed” as my daughter called it. It matched me to this mattress and it is divine. I needed a mattress on the firmer side and I don’t like a lot of memory foam on the top as it makes me too hot and I can’t sleep. This mattress has a cooling layer and it seems to working like a dream. Best of both now. I’m a single mum and with the help of the 4 handles it’s so easy to rotate all by my myself. The Sale gods were shining on me - as I did managed to get this mattress in the Sale. Pros - Best mattress I have ever slept on. Cons - My kids now want to sleep with me as it’s “soooooo comfortable”. So I best get saving again to buy them their own.

Used this pillow for just over a week now, previously my neck was very painful and I would wake up through the night with what felt like cramp in neck and lower head, but since I've been using this pillow it's all easing off now, I'm sleeping much better, feel a lot more comfortable and have less pain in my neck which I think will diminish over time. Highly recommend this pillow for anyone who suffers neck and head pain, I know it's expensive but it's better than constantly buying other pillows that don't help, I have quite a collection of different pillows now and this is the one I'll be sticking with for sure!

5 Nigel Shirley

From our first visit to Dreams in Aylesbury the entire process could not have been handled any better by Dreams staff, Sean was excellent, listened to our requirements and steered us in right direction and we are delighted with ourRelyon Mattress, very comfortable, we should have made the purchase earlier for did not realise how our old mattress needed replacing, will not make the same error again. Delivered exactly when promised by caring, careful delivery staff and taken direct to our bedroom and placed in position with old mattress removed, first class service throughout the process. Thank you Dreams

Very glad I didn't spend 900 on a mattress (as I was going to!), As this one is absolutely perfect and didn't break the bank (hurray!) Its soft on top, but firm and supportive... My partner and I do not roll into each other in the night as pre my previous mattress. We both sleep really soundly on this mattress which suprises me as he actually prefers really really firm memory firm mattresses that feel like concrete!! Doesnt give me back pains like my previous mattress, wake up refreshed. Something I was worried about for the low price tag! The edges are not reinforced so do sag if you sit on the edge of the bed - but its fine when you are asleep//roll onto the edge - ie, you dont end up falling off as with some mattress that are not reinforced!. It does get a bit hot with the memory foam, but after putting a bottom sheet on, it isnt as bad as it was on the first couple of nights.

4 Jillian Knight

Very good quality mattress! great support throughout and good degree of comfort. Mattress came rolled up so needed approx 24 hours to properly settle and for all the creases to disappear before I could use this. This time for the mattress to fully open was stated in the delivery note so I was not concerned about the wait. The only issue I noticed was the mattress is fairly heavy to move due to the number of springs inside, and there are no carrying handles on the sides that would have helped to assist with moving and positioning the mattress. Otherwise I am very happy with this product.

5 Eileen Smith

When I ordered 'next day delivery', I was sceptical. I need not have been. I received an email advising a next day delivery slot of 9.40 - 11.40 and the mattress was delivered at 11.15. The delivery guys were lovely carried it up to the bedroom. It was a great service. I only wish you did next day delivery black 5 drawer chest of drawers, as I have been badly let down by littlewoods and they had up to 15 days to deliver. Let me down badly and so I cancelled. I would recommend your company to friends and family. Thank you.

4 Nik Pringle

You need to ensure you have the mattress the right way up - indifferent nights sleep until I spotted it was upside down! getting used to it after a couple of nights, the edges of the bed are not as firm as our previous sprung one making it slightly uncomfortable to sit on the edge. There is also a tendency to roll together into the middle - hence 4 * as opposed to the full 5. I tend to find memory foam mattresses sleep "hotter" than normal ones - fine at the moment but may be a bit warm if we get a good summer.

5 Dawn

I was actually surprised with the quality and comfort of this mattress considering its very reasonable price. It was delivered rolled in several layers of polythene, which was necessary to contain it. It is a lovely deep mattress and so comfortable. I would recommend it to anyone, and am positive it has to be as good as any mattress considerably more expensive. Id been prone to back and hip aching problems on a mattress that wasnt right, this mattress solved that after first night.
