What Makes It Great

I have a chronic back problems, due to a spinal condition, so it was important to get the right mattress. After plenty of research, and helped by generous credit arrangements, I was able to go for one a little more expensive than my initial budget - and, boy, was it worth it! I absolutely love this mattress! It took a week or two to get bedded in (so to speak), but once it had, it has been supremely comfortable ever since, and I've had it 2 months now. The springs are nice and firm, but with that extra bit of foam topping, it gives a soft, luxurious feel. Highly recommended!

If you find yourself suffering from back pain then you may want to look at an orthopaedic (fancy word for firm) mattress like this one here. Firmer surfaces put less stress on muscles while sleeping which might be exactly what you need to help your back

These are made and manufactured in the UK, meaning that they all meet the same exceptional quality and durability that we expect from genuine UK manufacturing.

Individual response springs are basically pocket springs. Pocket Springs are a very common spring system that is featured in many hjigher-end mattresses. The level of comfort and support in a pocket sprung mattress will offer a great nights sleep for many years to come

This just means that springs and their supportive cage will go all the way to the edge of the product. Often handy for those that sit on the edge of the bed, since it doesn't do that weird collapse thing that other mattresses are prone to. Other benefits are that the risk of falling off the mattress in the middle of the night becomes mitigated which is always nice.

A decent height for padding material representing a barrier between you and the springs that make up the core of the mattress. This type of mattress should be comfortable as a result of the depth of this soft and comfortable material

Better than average amount of springs. Might be slightly firmer as a result but don't let this put you off. Firmer mattresses can still offer tons of comfort, the only difference is you get a better level of support as well. Ideal for those suffering from a bit of back or joint pain

Transformed my night's sleep

I bought this mattress just over 2 weeks ago and at first I thought it was going to be too firm. But after a couple of night's it quickly felt amazing and so comfortable to sleep on. Definitely not too firm after 'breaking in'. It has got rid of a lot of tension/ aches which I get from working a desk job. Amazing. When there is two people led on it you do not roll into one another, and neither do you feel like you are going to fall off the edge (as some mattresses have a curved edge). Excellent product, well done Silentnight. This mattress is worth every penny.

Great mattress

I bought this last month because I was having problems with a one year old mattress that started to dip in the middle. So pleased with this purchase. We no longer have back pains and our sleep has improved massively. I simply will now stick with dreams mattresses. This is a good investment and quality mattress that will last. Starts off firm and then the memory foam kicks in making your body as comfortable as possible. I would recommend this mattress to anyone who experiences back pain and can honestly say that we look forward to going to bed now.

Silentnight Ashridge Mirapocket Mattress

I'm going to be perfectly honest and say that neither of us had a great sleep for about 3 nights as we couldn't get used to the firmness of the mattress ... but having said that, the following nights, (and weeks) to date have been really comfortable and we've both been having really relaxing and restful sleep. I must comment here while I have the chance, the staff at the Talbot Green branch of Dreams were extremely helpful in helping us with our purchase and delivery.


I went into the rugby branch and bought this mattress three weeks ago, it was the best decision I have ever made. I can’t begin to tell you the difference it has made to my nights sleep and how comfortable and supportive it is which considering I have a bad back is fantastic. The staff in the shop were really helpful and knowledgeable regarding the different mattresses. They gave me time and space to lie on every single one before making my decision. I love it!

Delivery drivers were amamzing

Smooth and quick process ordering and applying for finance. Your delivery drivers are a credit to you!!! They called me in the morning to give delivery slot of two hours and also estimated when in that slot they are likely to arrive. When they arrived they were polite and helpful. The mattress is simply amazing. I suffer from restless legs and I have rheumatoid arthritis- this mattress supports me really well. We don’t want to leave our bed.

Much better nights sleep!

I have now owned this mattress for a few weeks and already I can start to see and feel the difference with my lower back. I am suffering from lower back pain where there is no quick fix and sleeping with previous mattresses gave me pain waking up in the morning, however now using a firm Silentnight Osterley Mirapocket mattress has helped me by giving me the support in the right areas that I need, whilst being comfortable for me and my partner.


I would say it is worth paying that little bit more for a good quality product. My previous mattress had lasted me at least fifteen years and I paid a good price for that mattress at the time. The new mattress made by Silentnight is very well made. It is taking me a while to adjust but I can safely say that my back feels a lot less achy in the morning. I just need to purchase the pillows that I tried out in the shop when testing the beds out.

Luxury matress

I spent time trying out various mattresses in bed shops and always felt the most comfort while laying on this one. I purchased the mattress and now that I have slept on it for over a week, I know that it was a great choice. It gives me a comfortable nights sleep and I am noticing fewer aches and pains all over my body in the day time. It is firm and supportive yet the gel top provides subtle softness for a little 'hug' on the pressure points.

Quality mattress

I purchased this mattress about 2weeks ago, was delighted with the service provided by the staff and their honesty for the product. It was a hard choice as there were two to consider, but I wasn't worried as I knew there was a 40days to decide if this was the one for me. It's a firm mattress which I usually don't like but because it also gas memory foam too it's firm but comfy. You don't feel you're other half move and it's very supportive.

Very Firm but comfortable mattress

I have problems with my back so require a firm mattress for support. The Price was a little steep but I truly believe you get what you pay for and this mattress is of excellent quality and will stand the test of time. My sleep has been excellent! The memory foam topping makes it comfortable and even though some have reported this can make it hot or uncomfortable I haven’t experienced this issue. Would definately recommend this mattress.

Great Service

I bought the bed a month ago and received very good service in the store with a good explanation of the products. We were very pleased with the service and finance option. Delivery was efficient and good communication from the logistics department. The mattress looks and feels great and the new pillows were worth the extra money. All in all a great end to end service and will go back when we need to get a new mattress.

Great quality sleep!

We first bought this mattress 3 years ago in double size. We are so happy with the quality of the mattress and of our sleep, so when we moved to super king size - there was no question - we went for the same mattress again. Both times we went for zero interest finance, which was quick and easy to apply online. Delivery time was reasonable, just over two weeks, given that mattress is produced after the order is placed.

Superb comfort

Tired of my Ikea mattress that only lasted 6 months, I decided to give it a shot at dreams. My partner and I did the simulator and this was one of the mattresses recommended. Big thanks to Grace from the store in woolwich. She was superb and recommended us this one. This is REAL comfort, don't spend your money on something cheap as it won't last. Delivery team was 5 star and I couldn't be happier with my choice!

Great mattress

I’ve had a memory foam mattress for over 10 years so which was the most comfortable bed I’ve ever had so was a little apprehensive about this mattress, apart from the fact that my feet don’t touch the floor when I’m sat on it. Lol. I am really pleased with it. I was recommended to buy this particular one by one of your staff because I mostly sleep on my side and she was absolutely right. Very comfortable.

Long awaited replacement

Went into chested store to try out mattresses and was taken with it and because it was what I wanted and no other would do I waited until it was on a special offer of 20% off as could not afford it at normal price of £999.99 that is the good thing about dreams that they have such achievable offers to enable you to purchase those big tag items and could not be happier with the new mattress

So Comfortable

I bought this a month ago and I can honestly say it’s fantastic. If myselfmor my husband move in bed we hardly feel it as a pose to my previous mattress I felt like I was in bed with zeberdee. I also suffered from a bad back and I feel that this has also been a lot better since the purchase of this mattress. The whole transaction from selection to purchase to delivery was just brillinant

Best sleep I've had in long time

I bought this mattress few months ago. I wanted a firm mattress that doesn't collapse or sink under my weight and honestly speaking when I first got it I thought it's way too firm it felt like sleeping on the floor, but after few nights it adjusted and wore in a little bit. Now It feels perfect and I find it hard to get out of bed in the morning that's how comfortable it is! I recommend.

Can't beat a nice firm one

Well we went and tried what seemed like a million different mattresses and after speaking to the chap in our local dreams he suggested this one. The misses has a bad back and is extremely fussy about he mattresses. Best night sleep we've both had in years extremely happy with the a purchase especially when we bought it online £200 cheaper than it was in the shop a week after we saw it.

Very comfy!

We bought this a couple of months ago and I am still so pleased with it! It is firm but the memory foam layer on top makes it so comfy. Aches and pains I'd always get in bed have disappeared and I am able to sleep on my back pain free for the first time in years. Also great as partner moving around next to me doesn't disturb me anymore. Very happy and much more rested!

A Superbly Silentnight!!

Having recently purchased the 'Silentnight Osterley' mattress. My husband and myself have thoroughly enjoyed some really comfortable night's sleep.The mattress is very firm, but offers excellent support. We would highly recommend it!!. Also we would like to say a 'big thank you' to Jaswant at the Wednesbury store for his help in choosing such a high quality product.

I love my new mattress

After being ill with a connective tissue disorder and months of troubled sleep, i can finally sleep with a new found comfort. After the sales rep in the Corby store walked me through all the different types and brands available, we narrowed it down to two. I chose one after spending time going back and forth trying them out. Equals the best sleep in months

Perfect comfort

The mattress is perfect and provides the level of support and comfort we had hoped. The entire transaction has been very impressive, despite the wrong mattress being delivered first time. The recovery of this mistake made up for the mishap in the delivery process. We are delighted with our new mattress and would recommend Dreams. Their staff were amazing!

Proper comfy!!

Had this mattress delivered last week after trying a couple of times in-store. Had a back op last year & since getting this mattress, I've had no sleepless nights & 2 lay ins! Cannot recommend this mattress enough. Firm but soft & proper comfy at the same time. This is one mattress that will not be returned! Even the cat loves it! :-

A comfortable and supportive matress

We have had this matress for 3 weeks now. We find it supportive and comfortable. We like the firmness of the matress to lie on but also how soft it feels. Dislike the weight of the matress. I am not very fit and to rotate the matress every week is quite a chore. Its heavy although there are handles of the sides which helps.

Amazing value

I bought this three weeks ago and was delivered two weeks ago. I cannot believe how comfortable it is. I have had some of the best nights sleep for a long time. It is as well that I am retired as I have had 'difficulty' getting up in the mornings. I am now questioning myself, why did I keep putting off buying a new mattress.

Very comfortable!

We bought our new mattress over a month ago and are extremely happy with it. We tried all the medium and firm mattresses in the showroom but found this one to be the most comfortable. Although firm, your body moulds into the mattress giving a great nights sleep. I wish we'd bought this a long time ago... luxury!

Extremely comfortable

Very comfortable mattress, delivery was seamless and delivery drivers were extremely helpful and courteous. Big shout out also to the dreams customer service team who ensured i made the right decision. Mattress has done wonders for my bad back, I am feeling the benefits already after only 2 weeks!

comfortable sleep

best mattress I have ever had well worth the price tag. I have suffered from a bad neck for years, the guys in dreams at clydbank took me around the shop testing the beds in till I found the right one and pillow. I have never looked back a good night comfortable sleep means everything to me. wow

Oh So Very Comfortable

I bought this mattress just before the start of 2017 and I truly love the comfort it gives. It also seems to have a wonderful feeling of warmth, which is wonderful for me. I thought it would take a little time to get used to it but it did not and I just love to snuggle into it every evening

Very good mattress

Thought I’d write a review after sleeping on this new mattress for a least a couple weeks. So far so good. It’s quite firm so exactly what I needed. I do need to change my pillows as they were also on the firm side and have been causing me a bit of neck pain because the mattress is also firm.

Great support and very comfortable.

Having had a foam mattress for many years I was a bit wary of buying this mattress. However, I needn't have worried. After the first couple of nights getting used to the change, I've experienced a much better quality of sleep than for some time. I would certainly recommend this mattress.

So comfortable

We have had our mattress for 2 weeks now. I had expected it to take a few weeks to get used to it, but that was not the case. The first night it did seem a bit strange but we both had a great night's sleep. The only problem is getting up when that alarm goes off in the morning.

Excellent mattress and service

I have had my mattress now for a few weeks and it's really so comfortable! Top notch. Great for us and baby too. The service was incredible. We had a 2 hour time slot as the day neared and they lay us know when they were due. Such efficient and fast at the job too!

Great Night's Sleep

This bed was purchased via Dreams' comfort guarantee. Originally ordered a firm bed and realised quite quickly it was too firm. Dreams replaced it with this one that I requested and am I so glad that that was possible. Getting the best nights sleep i've had in ages!

Excellent service

From start to finish off the order and till delivery it was perfect, Vini give me outstanding service and made sure the process was perfect and it was. I'd defiently shop with dreams again due to service from Vini and also delivery guys Many thanks Alan

Relaxing healthy sleep

Had this a couple of weeks now. Hassle free delivery,but the mattress has been brilliant. After six months off struggling after a injury at gym I have struggled. But decided to get a decent mattress and I'm actually sleeping right through night with no pain.

TV bed

I bought a TV bed from Dreams at the beginning of the year. The sales team couldn't have been more helpful and the bed was delivered on time. Everything worked and my sleeping has improved significantly. I would recommend Dreams as my first choice for beds.

Best mattress ever!

We love this mattress. Perfect firmness, all over until the edges. I used to have back pain, all gone now. Can't be happier!! Amazing delivery. They arrived at 9am, with the smile on their face and super kind, took shoes off, really amazing team!

A firm friend!

This mattress made our bed appear a little higher, and the firm touch was very reassuring. The indents are quite deep but do not affect your comfort, and the memory foam is not so deep that you are sinking into it. Altogether a comfy sleep!

Great service in store.

I know I paid quite a lot for my silent night mattress but the quality of the mattress sells itself, also the in store service in St Helens was exceptional all questions asked was answered accurately and informative about all products.

Brilliant mattress

Brought this some time ago and have now had a chance to bed it in (no pun intended) but i can't priase this mattress any higher than that. I certainly would recommend it to anyone who needs a firm mattress. It the one to go for

Wonderful comfortable sleep!

We bought this mattress on the spur of the moment having had superb service from the Dreams very knowledgeable sales assistant. The mattress certainly didn't disappoint, a wonderful good nights sleep and no more back aches!

Best Nights Sleep Ever

I had never had such a wonderful nights sleep until I bought this mattress, I was always jealous of people or disbelieved them when they said they feel refreshed and rested after a nights sleep, now I can say I do too !!!

Sleeping better!!

We have been struggling to sleep for quite a while! We were advised when we bought our new mattress that it would take about a week to get used to it - they were absolutely right! But now we are sleeping much better

Very comfortable

The mattress is very comfortable to sleep, I used to get back pain in older mattress. In this mattress I get sound sleep. No back pain after getting up. I am very satisfied with my purchase, thank you.

Best mattress ever!

My partner & I did the sleep test & this was one of the mattresses Dreams recommended. I prefer a firm mattress & my partner likes a medium mattress - this suits us both perfectly! Super comfortable!

my Ashridge

I didn't know what to choose as so many to tryout, but this is just the best I have ever had so comfortable and relaxing now I don't worry that I won't sleep at night it is like a dream come true.

Well worth the money

We've been using it for 2 months now and it's superb. Comfortable, soft feeling, quiet and extremely supportive. We've slept well every night since it arrived, even through the heatwave!

Fabulous Mattress

I’ve been sleeping on this for two weeks now and it is fabulous. I’m so comfortable, my sleep is now less disturbed. I wish I had changed my mattress a few years earlier . Well worth the money.

A soft top to firm support

Overall, sleep has improved on replacing the mattress. The soft topper over the firm and individual sprung base is perfect. The material combinations also manage roll and heat extremely well.

Great mattress

I bought this mattress a month ago after my partner having really bad sciatica, best thing we ever done . Have both slept so well, really hard getting up in the morning. Well done Silentnight

Comfiest mattress ever!

I bought the Silentnight Osterley mattress a month ago after it was recommended as a match for me and my boyfriend by the Sleepmatch machine. We’ve never slept better and no more back ache.

Very comfortable

We have had this mattress for about a month now and both me and my Mrs are very happy with it. I haven't had such a good nights sleep in a long time. Highly recommended

Extremely Comfortable

This bed is extremely comfortable with the right mix of supportive and then soft enough at the top level to contour your body without the feeling of being in a hammock.

Perfect level of firm vs soft

First week on this new mattress and I have never had sleep quality like it! It's perfect. Very pleased with it - actually look forward to getting into bed at night!

comfort indeed

We bought this mattress for our 'spare room' and have found it a good investment, the comfort is just what we had hoped from our showroom testing.

firm and comfortable

We bought this about 3 weeks ago and after a couple of nights getting used to the firmness of it we are sleeping better and waking up refreshed.

Have just recently purchased this item and we could not be more content with the outstanding quality and comfort for an excellent nights sleep.

Amazing, took me and my partner a few days to adjust to a firmer mattress. The quality of sleep is priceless.
