For the highest standards of quality and safety
Drift into an undisturbed slumber with the Silentnight UltraGel 2000 Mirapocket Box Top Mattress. Featuring specially designed elements to elevate your sleep experience.
Pressure-relieving foam
At the heart of this sumptuous box top is a 3cm layer of UltraGel™ foam. Experience blissful pressure relief for aches and pains with this adaptive foam. Its strong bounce-back supports free movement, helping your muscles relax throughout the night.
Increased breathability
With an open-cell structure, the UltraGel™ foam allows for improved air circulation, minimising overheating during the night, compared to standard memory foam. Tested in their in-house lab, the Silentnight’s gel foam is proven to allow 5 times more airflow through the foam than regular memory foam.
Paired with soft white fibres, which also allow for increased airflow, you'll enjoy a fresher feel. These soft fibres add additional plushness to the mattress, enhancing the comfort for a deep, restorative rest.
Zoned support
The supportive core is made up of 2000 Mirapocket® springs. Exclusive to Silentnight, these springs boast a unique design that tailors support precisely to your body. Held within individual pockets, these springs react independently to each other, providing personalised support where you need it most. The zoned design targets the heaviest parts of your body and is scientifically proven to improve spinal alignment.
Strong edge
Along the spring system is a sturdy rod edge. Securing and stabilising the springs, this framed unit provides a durable border. Diminishing a ‘roll-off’ feel and maximising your sleep space, giving you maximum sleep space to reduce partner disturbance.
Finishing touches
The mattress is finished with a soft knitted cover and a breathable mesh border. The mesh border enhances airflow through the mattress. Working with the UltraGel foam and soft white fibres for a breathable sleep surface.

Extremely well made mattress and very thick, but I had to send it back as it was too uncomfortable. It's very, very hot and way too soft. I'm quite a light person, and was rolling into my husband from the first night. It's also really hard to turn over as I think the gel topper is too soft. The smell is extremely strong too

This mattress is very deep had to buy new sheets for it. I would have expected the comfort to be better than it is. As it has a built in topper and is medium to soft. I have woken with painful hips for the bed so I need to put an extra topper on it. Which I would have not expected. I did not get too hot due to the breath ability of the mattress.

a very good and very comfortable mattress. I have problems with my spine. A disc is touching a nerve and the mattress I had before I always woke up with back pain. Since I have this mattress I wake up like a normal person without back pain. At night I can say that I fall asleep faster because it is more comfortable and it doesn't heat you up very badly in the summer. The mattress is very thick and has several layers of sponge or whatever it is called. It is really very heavy I recommend that you have 2 strong people so you can move it where you want. I am very happy with this mattress and I recommend it with confidence

Really impressed with this mattress so far it looks and feels like something you'd find in a luxury hotel. The stitching and finish are really tidy and the depth makes it look super plush on the bed. As for comfort it's that perfect in-between: firm enough to feel supported but still soft enough to be cosy. I've had noticeably better sleep since switching and I'm not waking up with the usual aches and pains. It also stays cool through the night which is a massive bonus for me. No annoying noises when turning over either. Honestly I'd buy it again without thinking twice—it's made such a difference.

The thickness and comfort of the mattress really surprised me. The quality is great! I can't remember when I last slept so well and most importantly my back finally doesn't hurt. I regret waiting so long to change the mattress. I definitely recommend it!

So happy with this mattress i've not been disturbed by my husband at all since so my sleep has improved immensely! I wish I'd have had a new mattress sooner but this has been worth the wait. 100000/10!

Already so impressed with my new mattress I wanted comfort and support and this one has delivered on both. The structure and quality of the fabrics make it super cosy and the overall depth is dreamy. The finishing touches of the trim tufting and labelling all add to the luxurious and premium feel. Loving my new mattress and it has already delivered extra zzzzz's.

Upgrading my mattress felt like a big decision and one fraught with risk.. but with Silentnight being the most trusted sleep brand I put my trust in them and boy did they deliver! With the extra boxtop layer this is one chunky mattress and has real presence who knew a mattress could look so good?! Soft fabric sumptuous cloud like tufts and a stylish blue highlight colour. After never owning a super deep mattress before it feels like a real treat to now 'climb' into bed at night and despite the size we had no problem getting it up my terrace stairs and into position also my standard fitted sheets do manage to fit it.. just about! Now more importantly onto how it feels and what a treat it is.. I can be a restless sleeper and could easily wake up on my old memory mattress as it felt like a bit of an effort to shift over to a new position but the UltraGel seems to make turning in my sleep much easier and I can go all night without waking once. I'd say the medium soft firmness rating is accurate it has a little give and just enough sink in comfort that in that it means I cant move freely and I feel like my back is fully supported must be those 2000 Mirapocket springs working their magic! I am more than pleased with this mattress and expect to have many happy years of undisturbed sleep in it!
