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.

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.

Let me start by saying that I've owned this mattress since 28/11/21 So I'm in a pretty good place to review after just about 4 years of owning one. We bought this mattress after popping into a brick and mortar Dreams store and after much testing around the showroom we found that this one was the best by a wide margin. We prefer medium firm between us and some of the feature we were looking for were: - Being able to move around in the night without disturbing the other - Quiet, so no creaking of springs or scrunching of fabrics - Soft, quilted feeling top fabrics - Firm supports that didn't make you feel like you were being swallowed - Body heat distribution so that you didn't get really warm and uncomfortable when trying to sleep - Durable. I'd bought a lot of relatively cheap mattresses before springing for the Bridgwater and was hoping to get more than a handful of years before it started to sag and develop dips etc. Well. 4 years in and the thing is still pretty much perfect. We love this mattress! There's hardly any wear on it at all in spite of almost nightly use since the day it arrived. When I sit down on it, it's still as medium firm as the day we bought it. I'm a tall, heavy bloke and my wife is around half my weight so it'd be easy to tell if the durability was poor because our old mattresses started to look a bit like a skate park ramp after 4 years but the Relyon hasn't so much as developed a dip where I sleep. How's that for durability? This is a high-quality, very comfortable, super durable mattress that's still going strong 4 years in. If you're looking for something comfortable, quiet, firm and doesn't feel like a bouncy castle when your partner gets up for a glass of water in the night, this is the one for you. Cheers Dreams and Relyon!

After trying the same mattress owned by a family member, I was keen to get one of my own. I've always preferred sprung mattresses but I'm not getting any younger, so hard to consider something a bit softer. However, I find memory foam extremely hot and it doesn't support the body. A natural latex-sprung matters seemed like a good compromise. I have not been disappointed. The mattress is firm enough to give good support, while being soft enough to avoid aches. Also I like that the mattress is quite thick, as it adds height to the overall bed, which keeps me away from the ground level cold air, and makes it easier to get in and out of bed. A big plus point about this a mattress is that it works well with my adjustable bed frame. The mattress, despite its thickness, adjusts with relative ease. Obviously a thinner mattress would be more suited to an adjustable bed frame, but I'm very happy with this combination and it works very well. So far, this has been the best matress I have ever purchased, and I plan to buy more for family members in the near future.

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

Generally appreciative of the superior back support offered by this piece although individual spring design occasionally falls short on expected comfort levels. Overall, exceptional orthopaedic advantages and satisfactory pressure relief makes it a worthwhile purchase.
