Becky's Thoughts On The Silentnight Osterley 1000 Pocket Memory Mattress

The Silentnight Osterley mattress is one to impress, with 1400 pocket springs (Silentnight call this the Advanced Mirapocket Springs with Zoned Support) and a firmer tension this mattress is ideal for those looking for additional support, or, with back and neck related pains from an existing mattress. We have found through our own tests that pocket springs perform better than the equivalent open coil springs often included in cheaper more budget-oriented mattresses and the more springs, the better.

Further to this, the Osterley mattress by Silentnight features an impressive 8-year guarantee, something we find fairly rare in the industry and a welcome change, along with a wide array of other features including genuine UK production, air vents for additional breathability and handles that allow for quick and easy rotation (useful for helping prevent uneven settlement of fillings).

Finally, this mattress features generous amounts of memory foam via the “Silentnight responsive Memory Foam comfort layer” which is an innovative NASA-produced material specially designed to allow the user to sink into, moulding to you and releasing pressure across the entire body.

What Makes The Silentnight Osterley 1000 Pocket Memory Mattress Great?

Comfort Grade - Firm

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

Individual responsive springs to provide tailored support

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

Edge-to-edge springs for maximum sleep space

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.

Scientifically proven to provide superior spinal alignment and posture

4 Handles

Handles make it easier to flip and rotate a mattress. Mattresses should be rotated and/or flipped every 3 months, without handles this can become cumbersome and so consider this a plus point for saving hassle down the line.

Metal Air vents

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

Rotate head to toe weekly for the first 3 months, then every month thereafter

Spread evenly any wear that develops over time by rotating the mattress every week for 3 months then every month thereafter. Not only will this increase the life span of the mattress it will diminish indentations that build up over time. Indentations which could otherwise cause discomfort, back pain or poor-quality sleep.

Advanced Mirapocket zoned support to provide superior spinal alignment and posture

1400 Pocket Springs (King)

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

Customer Reviews For The Silentnight Osterley 1000 Pocket Memory Mattress

Based on 100 review

Best mattress we’ve ever owned!

We went into store to pick a new mattress as our previous super comfy Sealy finally needed to be replaced. We used the Dreams Sleepmatch tool and Miles helped us to understand the best matches for us. The first mattress we tried was this one and it was absolutely perfect, and though we did try the others recommended, nothing came close. Delivery was super quick - within a week- and we have slept so soundly ever since. My sciatica is subsiding and our sleep is no longer interrupted. It’s so supportive- the memory foam top gives a bit of comfort but the mattress is firm and fully supportive. It’s just as comfy to sleep on your front as your side or back, but I fidget so much less now because I’d the added support it gives. I’m just sad I didn’t switch sooner- this mattress is genuinely the best mattress we’ve ever owned and I’m so glad we chose it over a number of the online competitors who were offering great deals at the time.


Great Sleep!

Excellent service when we bought this mattress. It was one of the recommendations for us on the machine (cant remember the name of it sorry) but was the last one we tried. Bought it in black friday sales as at full price it was outwoth our budget. Delivery team were excellent, calling me with a 2 hour window then 15 mins before so i could nip home from work to receive. Hubby and I both sleep really well on it. No aches and pains, fantastic item. A bit heavy to rotate top to toe but then it does have over 1400 springs in it!


osterley mirapocket mattress

i have found dreams beds very good to deal with, found the relevant mattress on line,at a very good price i spoke to an agent on the telephone, enquiring about the various qualities of the mattress, sorted out the details and ordered our mattress, the two young men who delivered the new mattress also picked up our old mattress for recycling and took the new one to the designated bedroom, these two young men were very efficient in delivering our new mattress and taking away our old mattress, all in all a very good experience.


Silentnight Osterley Mirapocket Mattress- Amazing!

This mattress was one of the ones recommended to me after trying it out in store using the matching technology. By far the BEST decision/ purchase I have made in a while. It's still early days but I no longer wake up feeling stiff with back pain. I can't remember the last time I slept so well. The perfect blend of firmness, support and comfort with the added layer of memory foam which makes all the difference. Would 100% recommend spending that bit extra for the quality of this product as it really is worth every penny.


Amazing comfortable mattress

I wasn’t sure at first when the store suggested a firm mattress as I was always used to a medium firm mattress but I was pleasantly surprised. As a side sleeper it provides adequate support to the back and is very comfortable. I was taken aback with the price but it was definitely worth every penny as it’s something you will be using every night so you want to ensure it’s suitable for you even if it costs a little more than you expected. Very happy with this purchase!


Got what I expected.

I didn't want an ortho mattress but at the same time I was looking for a comfortable mattress which can provide reasonable back support which it did. I have tried multiple mattresses even by silentnight but they have truly outdone themselves with the osterley series. Dreams Grimsby Team was spectacular. They helped us select the right mattress and I am really glad they listened to our requirements and were able to guide us towards making the right choice.


So comfortable!

This was the first time that I was choosing a mattress just for myself. After receiving this as a recommendation by the Dreams in-house assessment computer, I chose it as the most comfortable of those offered but was nervous that it might not be as comfortable as the mattress I was replacing (which I've loved for 12 years). It is absolutely perfect and so, so comfortable - I look forward to sleeping on it every night. Great product!


Extremely comfy, great quality.

We chose this mattress based on the match process in store. I didn't know what to expect with this process and was slightly dubious but it minimised the amount of mattresses we looked at, as there are so many, and really helped us decide on the firmness level. It suited both of us and after sleeping on it for around a month now, I can say it is extremely comfy and helped with some sleeping issues.


Very comfortable

Having had a bad experience with a boxed mattress, we went to Dreams. We were assessed by the machine in store and it suggested some options - the Osterley Mirapocket was one. We haven't slept so well since it arrived. A good, firm, mattress which supports both of us well (despite being different weights and one of us having joint hypermobility). Would highly recommend.


Silent night Osterley mirapocket mattress

Great quality, comfortable from first night. Wake up refreshed without aches and pains. It was a considered purchase and more expensive than I’d normally pay BUT well worth the extra money, no edge sagging. Would recommend spending the money. I bought one for my daughter as well, she has had spinal surgery and it’s made a huge difference to her, sleeping comfortably.



I have found Dreams to have great service, both Instore and online. Ordered mattress online and only took 3 days, managed to get Black Friday discount which was a bonus. Really firm mattress but soft top covering - making for a great sleep as I have arthritis in my spine, this mattress has enabled me to have restful sleep that I haven’t experienced in 5 years !


Brillant Sleep

Brought Silentnight Osterley Mirapocket Mattress in August 2020 and over the months me and my husband have been getting use to sleeping on a very comfortable mattress. We should have brought one years ago as the mattress is very soft and warm. Don't seem to need the electric blanket on for so long with the new mattress as it retains the heat very well.


Truly Silent night sleep

We decided to change our mattress and were looking for a firm mattress. The Silentnight Osterley Mirapocket is absolutely fantastic and have since enjoyed our nights sleep. Ordered in local Dreams store, delivered efficiently and advice given as to the care of the mattress. Excellent product and excellent service. Thank you to all.


Good night’s sleep & pain free mornings.

This is a sturdy, but incredibly comfortable mattress. It allows us to fidget and movie without disturbing each other. My husband says that his shoulder and back pain has reduced considerably since getting this mattress. And I have slept much more soundly. Highly recommend and worth paying that bit extra for.


Excellent nights sleep

Really needed a new mattress I would not go anywhere other than dreams, even though we were shopping under COVID conditions the gentlemen was a true salesman told us what different mattresses we could have and explained the difference between the ones we wanted it was excellent customer service thank you


Hotel kind of sleep

I received this mattress yesterday and had my first night sleep. What a difference it made. I feel so rested, had a deep sleep, very comfortable for a firm mattress. I feel my back muscles being supported as I do suffer with back problems. Really happy with my investment.


Worth every pennie!

We bought the mattress 2 weeks ago and me and my girlfriend have had no complaints about it! Its very comfy ! You usually take a month or so to get used to the mattress but with this one we didn’t need that long to get used to it, perfect nights sleep we are having!


Good firm comfortable mattress

We bought this a month ago and have been really happy with it. My husband prefers a nice firm mattress, so I wasn’t sure about getting this one. However I really like it now. It’s comfortable and I am not aware of my husband turning in his sleep which is good


Brilliant mattress

It’s a silent night mattress. That should say it all. Never had a bad one, this is super comfy. It weights and absolute tonne as it’s a king size so you might want two people when moving it about, that’s the only downside.


Good new mattress

Great help instore choosing the mattress and the matttess has been comfortable and provided a good nights sleep after our old one. It is supportive yet soft enough to provide a good soft comfortable night's sleep.


Mega in every way !!!

Well what can I say , this mattress is mega !! Like having a hotel comfort in your own home . Perfect in every way .. no more bad nights sleep, no more back ache .. my only wish is that I had bought it sooner ..


A good night’s sleep

It’s is what it says a very comfortable bed that holds your body at let’s you get comfortable in any position you sleep in A good night sleep has been had since getting my new mattress Thank you Dreams


The best sleep

I bought this mattress a month ago..and believe me..I have felt a major difference in my sleep..and it's all positive... So, go ahead..visit dreams and check what best suits your need and buy the product..


The best mattress ever

Best mattress I’ve ever owned, I’ve not slept this well in years. Sleeping on this mattress hasn’t caused any back pains. Perfect level of firmness (for me and my partner), no dips in the mattress so far.


Amazing Mattress 10/10 from me.

Fantastic mattress. Been suffering with back issues for over 4 years and within weeks this has helped me get back to exercising again. Firm with a thin sheet of magic softness on top. I highly Recommend.


very good

I brought this a couple of weeks ago as my husbands back was hurting due to our old mattress and every since we have started to use this mattress the pain had gone and he is having a better night sleep


No pain No stiffness in back

I used to have bath ache and stiffness every morning, and thought that it is because of my posture But once i started on this new mattress no pain no stiffness Amazing Best investment Great quality


A perfect nights sleep

After being a little sceptical over the dream sleep machine in store i have to say we are having great nights sleep now, couldnt ask for better, definitely worth changing to a new mattress from dreams


Silentnight Osterley Mirapocket Mattress review

Excellent product. Very supportive whilst extremely comfortable. Anyone with back problems will see immediate improvements in the quality of sleep and reduced stiffness and discomfort in the morning.


Great Mattress

Found this mattress using the machine in Dreams. It was the first on the list and after trying every other mattress in the shop we came back to this one. It’s fantastic and ticks all boxes.


Firm ortho mattress

Love the firm feel of the mattress however did also purchase a mattress topper to give a little bounce. Fantastic service received from the gentleman in the Dreams store Reading.


Like sleeping on a cloud

Quality firm matress

I bought this last month and I am so glad I invested in this mattress. Well made, it gave me the best nights sleep in ages. And Dreams delivery service was excellent.


Good firm mattress.

Good firm mattress. Still early days, but very happy with the balance between firmness and comfort. Not a cheap mattress, but quality and build seem worth the price.


Service of the company and quality of the mattress

Amazing quality mattress with an amazing service. A huge thanks for Lana and Kevin (Delivery team) that work effortlessly during those times and provide top service!


Dream come true

I bought this three weeks ago, I want to say one thing only " I am waiting disparately to my bed time " it is the best mattress in the UK if you like firm ones


Nicely firm and comfy

Our new mattress suits us wonderfully! Feeling so much more rested after a good night sleep, with less tossing and turning due to a better lower back support.


This is the best buy ever.

Before this mattress I was having a hard time sleeping. Not now I ain't. I thought sleep on the clouds was a figure so speech until I bought this mattress.
