Silentnight

Silentnight is one of the most recognised and established mattress retailers within the UK. That’s not all they do though, they also sell all-things bedding meaning you can get bed frames, sheets, duvets and pillows too. For those unaware, Silentnight is one of the more long-standing manufacturers, first entering the market back in 1946 and providing a good nights sleep ever since.

Silentnight are truly dynamic in their desire to provide good sleep for everyone and in doing so there is a wide range of different mattress types available. Ranging from bed-in-a-box to traditional mattresses, soft to firm and gel to eco comfort fibres, there really is something to fit every budget and comfort market. Read on to see how Silentnight mattresses stack up against the competition.

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.

Silentnight Owner Satisfaction

Satisfaction is at the core of everything Silentnight does and it’s evident through their tight relationships with both the consumers and retailers they work with. With the wide range of different products there’s something for everyone and thanks to advancements in technology surrounding edge support, roll-together prevention and better comfort layers that are both durable and luxurious, satisfaction has never been higher. Customer feedback is strong with many of the mattresses in the line-up being some of our highest and most well-reviewed. People particularly love the body contouring ability of the pocket springs, while the eco comfort fibres provide a sustainable and comfortable top layer.

Silentnight Supportiveness

Supportiveness is where Silentnight really shines. They’ve adjusted their offering over the years to focus more toward medium and firm tensions which naturally contour to the body better and help to alleviate back and neck pain. Silentnight also deployed an array of different support systems to further assist with adequate tension with the Mirapocket base layer proving the most popular and suitable if you are looking for additional support.

For those that suffer from back pain you may find the models within the range that feature hand tufting to give an additional bit of support.

Silentnight Durability

The average mattress is replaced at around the 7 year mark, that’s why it is so important for the durability of the mattress to hold up over time as the price point regardless of model is also going to be a considered purchase. With Silentnight, we have decades of proof that the mattresses truly stand the test of time and while our preference will always be that mirapocket layer over miracoil for increased lifespan, either should generally be suitable.

Another consideration in Silentnight’s favour is that the primarily spring based support layers are typically more breathable than their foam counterparts. Breathability means you are cooler and the mattress absorbs less moisture over time. Moisture over a long period of time can affect lifespan, performance and health.

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.

This is the first mattress I've ever bought. That's not to say I've never had a mattress in my possession before, it's just that, at the age of 32, this is the first one I have actually purchased myself. To an inexperienced customer, the world of mattress shopping is a daunting and complex domain, populated by a practically endless set of variables which one might never have previously considered, including 'pocket springs', 'coils' and 'memory foam', on top of the standard 'three amigos' of retail: price, brand and size. A visit to John Lewis with my girlfriend (a mattress-buying veteran who provided a welcome guiding hand) one evening after work provided an opportunity for us to get to grips with some of the many options first-hand. This was an investment of time I recommend to anyone in advance of considering making such a life-defining purchase online. I learned from this trip that the upper limit of what one can spend on a mattress is practically (but crucially, not literally) infinite. This was also the point at which the inherent gamble involved in the endeavour of mattress-purchasing was laid bare to me, with the stark realisation that no amount of casual testing of a mattress in-store could ever be sufficient to know what it would actually *be like* to sleep on one, let alone spend hundreds - and probably thousands - of nights cuddled up in (hopefully) restful slumber. After literally minutes of consideration, we left the store with a reasonably-priced, reliably-branded double 1200 pocket sprung memory foam option in mind and gainfully treated ourselves to dinner at an American BBQ restaurant as reward for our evening's work (which was, as it happens, dimly-lit and somewhat disappointing, though this is not our concern here). In the end, we went to Mattresses Online and bought what looked like a similar option, except with 1000 not 1200 pocket springs. Our experience thus far has been positive. We have not felt at all poorer for the 200 less pocket springs, and the memory foam element provides welcomingly soft cushioning, like laying down into the warm embrace of soft, yet firm, human flesh. I fully endorse this mattress.

I bought this 2 weeks ago and it’s been amazing so far, the pocket springs combined with the memory foam pillow top makes this bed very comfy and a dream to sleep on! Far better than my old simba hybrid mattress as that one was all memory foam, Good pocket springs from a reputable company like silent night are the way to go! And the fact this bed has a pillow top to make it that lil bit comfier is great, the pillow top is lowkey essential.. The bed come a bit firmer than I’d have liked took 3 nights to break it in, then it was perfect and it’s been very comfy ever since! I didn’t see this bed in store as it’s online only but I’m so glad I went with this one absolute dream! Only negative I do have is the fact it took 2-3 weeks to arrive which meant I had to sleep on my neighbours 10 year old mattress while I waited for it to come, defo worth it though. Positives • Very comfortable • Pocket springs provide adequate support without reducing any comfort • It looks like a well built mattress that will last a long time • 8 year guarantee for a extra fee but wasn’t too expensive for the peace of mind provided • Look for excuses to get to bed earlier now • Perfect size (little bit smaller than my simba double but works well with my bed frame) • Good height mattress! • Mirapocket zoned springs are a great help to provide support & comfort Negatives • Took what felt like a month for the item to arrive • Can’t see the item in any store in the Uk for some reason it’s online only which is annoying • No handles on the sides so turning the bed round is a ball ache!! Overall I’d give it 5 stars so far I may do another review 6 months in and let you all know how I get on with it as I’m aware mattresses can change from 2 weeks - 6 months hopefully this one stays comfortable and supportive it looks well built so I’ve got a feeling this will be the case..

This is a REALLY firm mattress, like sleeping on a floor. That is just what I wanted.I have a genetic condition called Ehlers Danlos Syndrome, which means my skeleton is not held in place properly due to my connective tissue being 'floppy'. This is the best mattress I have ever owned (far better than 'luxury' brands costing upwards of £1,000) and supports my skeleton perfectly. At last, I can have a comfortable night's sleep and not wake up with dislocated joints (yes, that does happen) and severe pain all over my body.So, for me, this mattress is heaven itself.However, you have to realise that this is like sleeping on a breeze block for most of your body. If your current mattress is saggy, it is probably because it's old or worn or hasn't been turned properly. Do not buy a 'very firm' mattress to replace it unless you want a really HARD bed! Pretty much any new mattress will be firmer than an old one. This mattress is designed for people who are obese or disabled or have an extremely bad back that is permanent. I would imagine that for other people it would be way too firm. So beware of that before you buy.But if you know you want a very firm mattress, then believe me, you can't do better than this for the price. So long as you rotate it every week initially as recommended (after two months you can rotate it once a month), it does not sag. I have had mine about six weeks now and there is no sag whatsoever.

Bought the super king size online. I can not fault this bed, however it is a VERY FIRM mattress - after 2 weeks sleeping on it it is now beginning to soften slightly, my husband who is over 6ft and weighs around 15 stone thinks it is wonderful, it is a bit hard for me though (but is getting there!) I was told in store to avoid this Miracoil mattress as it was not pocket sprung (which is why they don't have them in store to try out) but I think it is absolutely fine, we didn't have thousands to spend on a bed and bought this hoping it would last for a few years - it seems very well constructed and looks like it is built to last, I'm glad I didn't listen to the instore sales pitch for the pocket springs! There is absolutely no roll together, in fact I tend to fling myself as I swap from my side onto my back and then onto my side again and hubby doesn't even notice I'm moving now! The drawers are on the small side but are sturdy and well built, and the dark grey fabric of the base is a good neutral colour. Fab delivery team, very curteous and clean - even put shoe covers on, and came within the 2 hour delivery slot I was given. Definitely recommend this bed.

Highly recommend. My wife has struggled for years with back pain, due to her having HEDS. The pain she got from sleeping in bed, caused stiffness and pain throughout the day. After some research we discovered we needed a firm spring mattress to solve this, to fully support her spine. We went into our local store, and tried every single bed.. and this one, was the one. Bought it, and had it delivered. It took a good 6 months for our backs to become adjusted to the firmness of this mattress, as the ones in the store are softer from being tried so much. We bought the tempur waterproof cover, as it is breathable and has the highest reviews. We also bought the John Lewis dual layer mattress topper to help us while we was getting used to the firmness. 6m on and we are fully adjusted to the mattress, every night we sleep peacefully, and most importantly no more pain in my wifes back. I can't recommend this item enough, its a complete gamechanger. I feel so well rested every morning, it brings a smile to my face everyday to wake up, and to get in at night!.

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.

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.
