Becky’s take

By Becky Reeve

Checked against current models and prices in October 2026

I'd buy a Flaxby over a Silentnight, because everything Flaxby makes is pocket sprung with natural fillings. Silentnight sells more of the Vilana and the Ortho Dream Star than anything else, and both are Miracoil, Silentnight's trademarked continuous coil, which behaves much like open coil. The springs are wired to each other, so the bed sags where two people meet. Both brands are sold at Dreams, so lie on the Silentnight first and then the Flaxby.

Silentnight does make pocket-sprung mattresses. The Air Plus 800 at medium-firm and the Air Plus 1000 Mirapocket at firm are the honest end of its range, though the names are clumsy, and Flaxby's are no better. The 16150 is a spring count, and a spring count in the tens of thousands is a boast. Silentnight is the bigger name by a long way, but it's bland, and I'd rather point you at a plainer label with springs and natural fibre behind it.

Buy the Silentnight if you want medium-firm, because Flaxby has nothing at that tension and the Air Plus 800 does. Everyone else should buy the Flaxby, the 16150 for medium or the 8450 for firm.

Head to head

Silentnight has 53 of its 70 mattresses sprung and 3 all memory foam; Flaxby has sprung throughout, with pocket springs or a hybrid build in every model. Only Silentnight offers latex, in 6 models. Silentnight runs from soft-medium to extra firm, and Flaxby runs from soft to extra firm. Silentnight is the budget choice of the two: Flaxby's cheapest mattress costs several times as much. Silentnight's owner score rests on far more reviews (30,352 against 1,543), so treat Flaxby's number as the less settled of the two.

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.

Flaxby

Flaxby mattresses are sold exclusively by the popular retailer, Dreams. The collection is a more up-market premium brand within the lineup and uses an impressive array of comfortable and soft materials in the upper layers of their mattresses to ensure a natural and comfortable sleeping surface. Flaxby are focussed toward ensuring a greener and fresher sleep that is more environmentally friendly. That’s why they utilise 100% recyclable spring systems and natural fibres to help safeguard the environment for future generations.

A feature unique to Flaxby includes their new all-seasons lineup which sees a two sided mattress which has different comfort layers on each side, giving a “warmer” side and a “cooler” side.

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. Customer feedback is strong. Comfort and support are what owners bring up most, and a good price comes up often too. Where owners are unhappy, firmness is the most common reason. A mattress harder than they expected is the commonest complaint, a smaller group found theirs too soft, and one owner wrote “Too firm for us”.

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.

Flaxby owner satisfaction

Comfort and support are what Flaxby owners praise most. One owner wrote “I have found it extremely comfortable and I get a good sleep”, another that it “Feels so supportive”. The edges get a mention too, with one owner noting that “the edges are very firmly sprung so if you sit on the bed to put your socks on, you don't slip off”.

The lower scores are mostly about two things. Some owners of the pillow top models, the 4450 in particular, say the surface softened or dipped early: “after 6 months it dipped massively and became unbearably uncomfortable”, and “after less than a year much softer and big indents where we lie”. Others found the delivered mattress was not the one they remembered from the store: “The bed in the showroom was so comfortable, this one is not”. A few also mention the natural-fibre smell. One owner found it “a bit ‘sheepy’” and quite liked it, another said “The smell it exudes is reminiscent of farmyards”.

Flaxby supportiveness

Flaxby mattresses have a great deal of supportiveness thanks to the Cortec™ and DNAir pocket spring systems on offer within the lineup. The Flaxby range is what we consider to be a traditional lineup with typical high quality manufacturing processes that result in luxurious and supportive mattresses. Pocket springs have generally remained unrivalled over the years and are my own personal favourite support layer when it comes to offering good tension for back and neck support. Many of the products on offer are available with multiple tension options which means you have a choice around how firm you would like the product to be. Depending on how you sleep (front, back, side) to how much you weigh are all determinations when choosing the right supportiveness.

Flaxby durability

Flaxby mattresses will typically perform better in terms of true longevity than many other mattress suppliers due to their large investment in good quality pocket spring support layers combined with tried and tested comfort layers of wool and hemp. The combination of these materials gives customers confidence but also the retailer, Dreams. This is evident in their backing of this product lineup with the 7 year guarantee that ensures long standing support in the event of any manufacturing defects. The price point for Flaxby may often price certain people out of the market who are looking for something a little cheaper, however, when you consider the lifespan and the cost per night of sleep as a result, the Flaxby offers a fantastic opportunity for sleepers thanks to its durability and comfort.

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..

Good Points: 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. Improvement Points: Why oh why are there no turning handles? Especially when this mattress is for people with bad backs etc? Come on manufacturers, this is so silly - just put handles on the mattress! If you are slim, please read the 'good points' - this mattress will probably leave you covered in bruises as it is so firm, so beware!

I have been sleeping on the Silentnight 1400 Ultra spring mattress in Super King size for a few weeks now and I think I have got a pretty good sense of it. It's a firm mattress definitely not soft or squishy but that's exactly what I was after. It feels properly supportive especially for my back. Since switching to it I have noticed I sleep better with less tossing and turning and no more waking up with back aches. Hubby is especially happy.One thing to note is the height. This mattress is thick and if you've got it on an ottoman bed like I do it sits pretty high. It's not a dealbreaker but depending on your room setup or how tall you are it might feel a bit too raised. In smaller rooms or with lower ceilings it can feel a bit oversized.Moving it into place was a bit of a mission. It is really heavyaround 50kg and the size makes it awkward to handle up the stairs into the bedroom. Took two men to get it upstairs and onto the bed frame. If you've got tight stairs or narrow hallways make sure to plan ahead. It's not something you want to do solo.The mattress is single-sided so you can't flip it but only rotate it. That's fine for me but if you're used to flipping your mattress every so often just keep in mind that this one isn't designed for that.The mattress came with a couple of pillows too which was a nice touch. Summing up it is a firm comfortable mattress with gel for orthopedicsupport and it feels like it is built to last. My back feels better and I'm sleeping more soundly. If you want something supportive and don't mind the height or the heavy lifting during setup i would say the Silentnight 1400 Ultra is a solid pick. Just make sure your room and bed frame can handle the size and maybe have someone around to help you get it into place.

Good Points: Extremely light, one adult can pick it up for king size. Delivery is on time. Nothing else. Improvement Points: Extremely regrets to purchase it by below reason 1. It is not 'extra firm' as it states from our experience, and my family member got back pain experience next day morning when sleep on it. 2. Extremely light, one adult can easily pick it up alone for king size, not sure the material is strong enough or not inside the mattress. Since my previous mattress of other brand is extremely heavy and even two adult need hard to pick it up 3. If partners sleep and move the body on the mattress, I will feel the mattress is moving so if sleep on it better not move often otherwise partner hard get to sleep. 4. Edge is not strong than center, so even sit on it the edge, it will collapse and not balanced on whole. If sleep on it, it's better don't sleep near the edge, and you will feel it is a little bit collapsed and feel uncomfortable. 5. This mattress not supporting people steps on it from CS reply and it is claims as misuse and no warranty will be provided. Indeed, the mattress is not damage just very soft when step or push it by hands. It will collapsed easily. So, if anyone have the same case with us that have cabinet on top of our bed, than you should consider seriously since you need to step on the mattress for put in or remove things from the cabinet. Its the first time I heard mattress not support people step on it and it will void the warranty. From our previous experience, it is normal usage since mattress should be a strong product. Indeed, the mattress not got any worsen condition when we step on it to test the mattress firm level, it just not feel extra firm and comfortable in our mind. 6. When i ordered the mattress, I did not take any picture, and CS replied that when we placed the order on Oct 2022, it don't provide 60 days trial period. I was very surprised since CS reply trial sleep is new promotion after we placed the order. I did not take any evidence so I can only believe and accept it. 7. CS are not able to provide any help on my purchase. Only said that we misused since it don't support people step on it and it is misused even it is not damaged. After few email conversation, CS replied that we don't have 60 days trial sleeping on the mattress when we placed the order. We are very disappointing on it since we have mentioned our purchase date and provide order no from the beginning of email conversation. 8. Even it is a cheap model , but not actually cheap in the market that can found in other shops with other brands. Next time I will considered more carefully when placing order. 9. For anyone reference, I am around 65 KG and my husband is around 85KG. So we are not heavy weight person in general. 10. Most people give high marks of the mattress quality, only little give low marks. We should believe in low marks person rather than high mark person review and we are regretting on it.

1 Scam

Ordered a different mattress which was clearly not a new mattress, it had felt missing and marks on it, so I made a complaint and was told they would exchange it but when they came to exchange it, they wouldn't because of the marks on the mattress which they were already aware of as I'd sent pictures, then when I contacted the consumers rights website, they said they had to exchange it and they were liable for the delivery charges but they wouldn't pay the delivery and we had to pay another £49 to exchange this damaged item, if you purchase from an online store, the consumer's website states that by law the company are liable for the delivery fees!!! t They wouldn't budge on that but exchanged the mattress, only this time they brought the wrong one being an extra firm mattress when we had ordered and paid for a firm mattress. We contacted Dream's again to explain and was basically told we were stuck with it. I'm a disabled lady and this mattress is absolutely crippling for both me and my partner whom isn't disabled. I would never use Dreams again. The delivery lad's confirmed that half of the mattresses that people are getting have already been previously returned from other customers which would explain why they are all so bad in the first place. A disgrace of a company. I don't expect to purchase a new item that has already been used and sent back god only knows how many times previously? So we're £400 out of pocket and have had to throw this mattress away because I wouldn't give it to my worst enemy because it's so bad! Go and look at the real review websites and not the one's like trust pilot who remove bad reviews or don't let you post them!

Owner reviews of Flaxby mattresses

5 Martin & Anna

We purchased the Flaxby 14450 pillow top mattress from Dreams after trying out the range of Flaxby mattresses in store. We opted for the Superking size with the split medium/soft support and the zipped option (essentially two singles joined together). I prefer the medium support whereas my partner likes the softer feel. Bear in mind, these are heavy mattresses and having the split mattress option makes it far easier to turn them, which you will need to do weekly for the first 3 months (then monthly thereafter). It has taken a long time for the mattress to fully bed in and feel comfortable to sleep on. If you're considering this mattress, be prepared for a full 6-8 weeks break in period to allow the materials to loosen up and conform to your body. When new, it felt very stiff with the sensation you're lying on top of the mattress, with not much give and with minimal support. My partner quickly got used to sleeping on her softer mattress, whereas with my medium feel mattress, I experienced lower back pain on and off for the first 4-5 weeks. The Dreams staff advised that the Flaxby mattresses do take a while to break in and conform to your body. Here's some tips that have worked well for us and are worth considering: Mattress support - this mattress really does deserve a quality bed base, preferably a pocket spring divan base. We initially used our old Superking bed frame with sprung slats. However, although the 14450 mattress is a deep mattress and should in theory work well on any bed base, we found that it not gel that well with the sprung slats, as the mattress tended to sag slightly. We have now switched to a sprung divan base and it's made a big difference to the feel, comfort and support of the mattress. Pillows - we initially used our Tempur cloud pillows with the Flaxby but we have since switched to Levitex sleep posture pillows (we opted for the small size). This has made a world of difference - no more neck and back pain! Duvets - we've always liked having our own single duvets rather than sharing a larger duvet so we can better control our body temperatures. My partner uses a weighted duvet whereas I switched to a wool filled duvet. The Flaxby mattresses do offer better temperature control compared to our old Tempur mattress. It is still worth investing in a quality duvet to really get the best sleeping experience.

WAOW. I’ve been using the dreamcloud mattress for the past 3 and a half years which was fine for the most part but I wasn’t liking the memory foam feel of the sink in the mattress so decided to try this pocket spring mattress. After ONE night I’m already loving it. The comfort is absolutely phenomenal. Firm but still pure luxurious comfort and you can tell the materials are high quality. This is the sort of comfort you get in 5 star hotels. Personally I’d never go back to memory foam or combo memory foam type mattresses like dreamcloud, Simba and tempur because in most cases the mattress will develop a dip or sink where you lie after a few months or couple of years and that doesn’t properly support your body whether you sleep on your back or side, and with this Flaxby mattress I feel I can just lie in pure comfort and not have to move around all the time trying to get comfy with the memory foam type feel of my previous mattress. This Flaxby mattress is extremely comfortable on your back and side and all the other 5 star reviews back that up. The simple truth of the matter is if you want a high quality hotel like feeling mattress you’re going to need to invest the money. You’re investing in your sleep, health, mood and comfort for every day life and when you consider how long mattresses last it’s absolutely worth it. The delivery team were also fast and fantastic two helpful gentlemen who took away my old mattress with no problem. I’d recommend this mattress or any other pocket spring mattress over this price range will he just as good I’m sure. I got this at 15% off in a sale so if you want a discount then wait until the next sale. I also picked the “firm” option not “extra firm” but I’m sure extra firm is supremely comfortable as well. Happy sleeping!

5 Ayup

I was extremely dubious about purchasing this mattress and had been looking at the reviews for a good couple of months before taking the plunge. I went in Dreams several times to lay on it and make sure I wasn't making any bad decisions. It felt like the mattress was just hugging you right back when you laid on it! Good support in the lower back area too as I have a permanent slipped disc and spinal arthritis so I had to be 110% certain I was getting the right mattress. I have now had this mattress for over two months. My patter goes like this: sleep on one side for 7 days, then sleep on the other side. Then rotate the mattress and repeat the first steps. It is quite heavy to rotate but I'm just relieved I have finally found the perfect mattress again after 13 years of agony and going through about 5 different mattresses! There is no dipping as I rotate the mattress regularly - I am only 9st just over so not really big enough to be making the bed dip. I have a mattress protector on the bed, and use medium pillows. I am sleeping like a dream. I now manage to have nights where I sleep right through without waking for the loo or with pain! I no longer wake up with back pain anymore. I really am one happy lady! Would definitely recommend this mattress to others BUT if you are on the larger side, go for a firm it will soften over time, as seen other reviews saying this mattress dips so I guess if your on the heavy side you may or may not have an issue. Have attached pictures of when I first got the mattress compared with 3 months later and as you can see, no dips and looks just as good. I also bought the bed frame from dreams too.

I have had this mattress for about 5 months now and how miserable I am. I suffer from back ache and have had operations on both shoulders. So my husband and I decided we need a new mattress that was softer and less painful for me to sleep on. On his advice I returned to the store numerous times over maybe a couple of months to test this mattress out. So I maybe lay on the mattress for at least half an hour turning and trying both sides of my body. I thought at last I have found the mattress for me and it would give me some much needed relief. After having little or no sleep for many years I thought I had finally found the answer. How wrong was I! I contacted dreams customer service and they agreed to send out an assessor. Very friendly guy who proceeded to use some kind of measuring method & calculation I think like a ruler, he measured the pillow top part of the mattress. According to him they do not consider its a fault if the measurement of thickness does not go below 3cm if my recollection is correct! So that was that and I had to accept that I was stuck with this very expensive mattress and as we had also purchased a new base, a very expensive mistake indeed! Like one of the other reviews I had read, I too wondered how the product from the showroom could be so different from the one I received! I feel that maybe the ones in the showrooms are to draw you in and then are all made the same in a factory somewhere. However, I was told these particular mattresses are made by hand in the Flaxby factory somewhere? This whole episode has left me feeling very depressed indeed! All I wanted was relief from pain and a good night's sleep. I feel I am actually sleeping worse than I was on the previous mattress. I don't know what the answer is as I have already gone way over 100 days trial, however did not think after just over 5 months I would be facing this problem! One other point I must make is that, under this '3cm' pillowtop the rest of the mattress underneath has a very firm feel. So all that is supposed to give you this soft, comfortable sleep is the 3cm pillow top.

1 Unhappy sleeper54321

Ok, so I have had this mattress a year or so now and I'm still wishing I hadn't bought it. From the off it sunk where I slept. The label said not to worry as 'it's just the mattress getting to know you'. I have a double mattress but sleep on my own so I tend to sleep in the middle of the mattress. My mattress quickly started to dip in the middle and I was finding this uncomfortable and disappointing, especially as it was very expensive. I left a review saying I wasn't happy and Dreams contacted me. They sent a furniture surveyor who reported that the settlement of the mattress was within their normal range. I have persevered with it but it is so sunken in the middle now that you can literally see it even with the duvet over it. I honestly would not recommend this mattress. If you are at all worried that you will end up with a ditch to sleep in, don't buy it! I was drawn in by the natural fillings and it was comfy in the shop, to lie on for a few minutes. But I probably wouldn't have even tried it if it weren't for Dreams computer 'matching' me to it. Well, what a surprise that two of the mattresses it recommended for me were two of the most expensive in the shop! I feel tricked and I now have aches and pains from sleeping in it. If you don't want to be fleeced for a grand and a half in return for sheer disappointment then don't buy this! And don't fall for their returns guarantee. They will only exchange it for one of the same value, and there is only one other mattress in the shop that costs a similar amount so there is little choice. They do not give refunds in part exchange for something cheaper!
