What our reviewers found

Pros

  • The UltraGel™ foam layer provides excellent pressure relief, aiding with aches and pains and supporting free movement during sleep.
  • Its unique open-cell structure design enhances breathability, making it great for hot sleepers who need a cooler mattress.
  • The presence of 2000 Mirapocket® springs offers a highly tailored and personalised support experience, catering to the body's heavier zones effectively.
  • Robust edge support ensures a stable and secure sleeping surface, reducing partner disturbance and allowing for the maximisation of sleep space.
  • The mattress is crafted by Silentnight, a brand with 70+ years of experience, offering reassurance of its quality, durability and commitment to safety standards.

Cons

  • The Silentnight UltraGel 2000 Mirapocket Box Top Mattress, while making use of UltraGel™ foam for pressure relief and breathability, could potentially fail to deliver the firm support desired by sleepers with specific spinal or alignment requirements due to its medium firmness.
  • The lack of a cooling technology, aside from the touted breathability of the gel foam, might cause discomfort to hot sleepers who can encounter heat retention issues typically associated with memory foam mattresses.
  • Though the mattress offers edge-to-edge support, the stability provided could be compromised over time, considering the medium firmness and single-sided design of the mattress, potentially resulting in sagging and lessening the lifespan of the product.

There's no denying the crucial role that a good mattress plays when it comes to quality sleep. Polls have it that one of the most significant impediments to a good night's rest is discomfort, and having the right mattress is integral in addressing that. Today, we look into the intricacies of the Silentnight UltraGel 2000 Mirapocket Box Top Mattress, a product that's garnered a fair deal of attention in the mattress realm. It has a medium-soft feel, an UltraGel box top and a noticeable 2000 Mirapocket springs, amongst other intriguing features, all of which we'll evaluate. Owners don't agree on how that medium-soft top feels: one calls it "comfortable and firm", while another had it down as far too soft and sent it back. Still, we're confident that our analysis will provide you with valuable insights to help you make an informed purchasing decision.

How we assessed it

Most of what you'll feel here is the top. A 3cm layer of UltraGel foam and mini pocket springs are finished as a box top over the 2000 Mirapocket springs. The whole mattress is 33cm deep and single-sided. I'd expect that to feel cushioned at the shoulder and hip, and I'd expect a soft top you can't flip to keep softening with use. Most owners are happy with the comfort, one finding it "firm enough to feel supported but still soft enough to be cosy", though another woke with painful hips and says it needs an extra topper. It's deep enough that one owner had to buy new sheets. On heat, the owner who returned it found it very hot, but others say they didn't overheat.

Design and features

The Silentnight UltraGel 2000 Mirapocket Box Top Mattress is an assortment of several carefully conceived designs and features that aim to provide its user with an unmatched sleeping experience. It has a medium-soft feel, endowed by the UltraGel box top design that features a 3cm layer of the resilient foam. This design facilitates pressure relief for aches and pains whilst promoting adaptive support that enables your muscles to relax throughout the night. The open-cell structure of the UltraGel foam allows for improved air circulation, thus curbing overheating which can be detrimental to the quality of sleep. With 2000 Mirapocket springs, the mattress provides personalised support that matches the shape of your body, ensuring that you're effectively supported where you need it most. This offers a knee up in ensuring spinal alignment, crucial for a good night's rest.1 It also comes with a robust edge support achieved by a rod edge frame along the top and bottom of the spring system.

Comfort

Comfort is no doubt the Silentnight UltraGel 2000 Mirapocket Box Top Mattress's strong suit. Its medium-soft feel delivers a level of comfort that's suited for every sleeper but does an exceptional job for those who sleep on their side. However, back sleepers and individuals with a larger body mass may find the mattress's support somewhat lacking, and thus might want to consider a product with a slightly firmer feel for better contouring and support. Regardless of these singular downsides, the mattress still manages to offer a reasonable level of comfort, owing to its adaptive UltraGel foam and the support from the Mirapocket springs that ensure your body is well-supported throughout the night.

Suitability

The Silentnight UltraGel 2000 Mirapocket Box Top Mattress offers a solid performance across the board but truly shines for side sleepers and individuals of average weight. The zoned support of the mattress aligns well with the contours of a side sleeper with noticeable hug around the contact points ensuring reduced pressure on the hips and shoulders. This level of contouring and deliberate zoning also provides support for back sleepers, with the only reservation being that a firmer product might offer slightly more support. Nonetheless, the mattress is a good fit for most sleepers and assures a comfortable sleep experience.

What customers thought

One owner gave the build full credit, calling it an "Extremely well made mattress and very thick", but sent it back because it was "too uncomfortable". Heat and softness were their main complaints: "It's very, very hot and way too soft." Despite being "quite a light person", they were rolling towards their partner from the first night. They also found it hard to turn over on the gel top, and said the smell was "extremely strong".

The verdict

After our close scrutiny of the Silentnight UltraGel 2000 Mirapocket Box Top Mattress, we can confidently say that it's a respectable player in the mattress market. It presents a thoughtful blend of comfort, support, and well-balanced features that indeed make it worth considering. However, it's essential to bear in mind that the mattress falls short in a few fronts; heavier users or back sleepers might find it less supportive. One owner also found it very hot, which could potentially be a put off if cooling is a crucial factor in your decision making. Despite these few misgivings, with its 2000 Mirapocket springs and UltraGel box top design, this product offers fair value for its price. If you appreciate the added comfort of a medium-soft feel and you're not overly concerned about the cooling aspect, then the Silentnight UltraGel 2000 Mirapocket Box Top Mattress could be a worthy addition to your bedroom.

Suitability

  • Back Sleepers 4/5
  • The amount of support offered from a mattress will vary depending on the firmness of the tension and the type of support layer used. Based on a person of average build.
  • Side Sleepers 5/5
  • If you sleep on your side you typically need a supportive tension that is not too firm, nor too soft. This is because your hips and shoulders need adequate sinkage.
  • Stomach Sleepers 4/5
  • Stomach sleepers need a reasonable amount of tension in the base support layer to adequately offer body contouring and help prevent aches and pains. Results will vary based on your build.

Performance

  • Breathability 4/5
  • Mattresses that feature breathable materials help promote airflow and keep you cool making for a more hygienic night's sleep.
  • Turning on mattress 5/5
  • Certain materials like memory foam can make it difficult to move about on the mattress while you toss and turn. Same too for pillow tops which can create a cloud like sensation which can make manoeuvrability challenging.
  • Stability 4/5
  • Depending on the type of support layer in place can have an impact on stability, edge to edge support and roll together prevention. Pocket springs of a firmer tension will have better stability than open coil soft tension, for example.

Ease of Use

  • Turning handles 5/5
  • Mattresses typically need to be rotated frequently and having turning handles can be massively beneficial, particularly in larger sizes which can become fairly heavy.

Odour

  • Initial Odour 4.5/5
  • Materials in mattresses, particularly memory foam and rolled bed-in-a-box mattresses can have an initial odour, this is typically short term and reduces considerably within 24 hours.
  • Long Standing Odour 5/5
  • Certain materials inside different mattresses can produce a small odour. Typically this is short term rather than long standing but there are minor exceptions.

Brand Rating

  • Overall Brand Rating 4.5/5
  • This is based on community driven customer reviews tied to product reviews and grouped together at a brand level to produce a score.

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!

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.

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.

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.

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

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!
