Tests & Verdict

Here we collect tests, guides and product reviews so that you can create a picture of what others think about the product. This analysis and review is based on my experience and 12+ years of industry insight.

Gel foam and pocket springs is a combination that will prove hard to beat, particularly with that medium tension offering mass market appeal.

Good for back, side and stomach sleepers alike in an average weighting.

Brand you can trust, backed by a strong guarantee.

All popular UK sizes available.

No euro size options despite recent news surrounding a growing market within the UK.

Gel foam can be quite a good cooling layer, ideal if you sleep hot but problematic if you already sleep cold.

Price point still quite high for some people, recent studies showed the sweet spot was just shy of £400 for a double.

Why our sleep experts loved it

Good evening sleep enthusiasts and have I got a treat for you today! I recently stumbled upon the Silentnight Just Bliss Gel Hybrid Mattress, and let me tell you, it's a game-changer in the world of sleep solutions. This mattress isn't just about providing a place to rest; it's about revolutionising the way we sleep with its gel-infused layer and a whopping 1000 zoned springs. It's like sleeping on a cloud that knows exactly how to cradle every inch of your body.

Who this configuration will suit

If you're someone who battles allergies every time the seasons change, this mattress might just be your new best friend. It's got the Allergy UK seal of approval, ensuring a sneeze-free, itch-free night. And for all my fellow back pain warriors out there, the enhanced spinal alignment provided by those 1000 zoned springs is like a gentle massage for your back. This means, in theory at least, that there will be no more waking up feeling like you've been wrestling all night! Plus, for those of us living in multi-story homes or flats, the convenience of this mattress being rolled up for easy transportation is a godsend as it means there will be no more awkward lugging a bulky mattress up narrow staircases!

Who it won’t suit

While I can personally see value and suitability in the mattress, that doesn’t mean it will suit everyone so if you're someone who's very particular about having a removable cover for easy washing, this might not be the one for you. Further, if your preference leans heavily towards a super soft or rock-hard mattress, the medium firmness of this one might take some getting used to. Ultimately the pocket springs in this configuration have fairly mass market appeal but will still not suit those with a heavier build or who require orthopaedic support.

Gel comfort layer benefits

The comfort layer of this mattress is where the magic happens. Imagine a layer that knows exactly where you need the most support and comfort. That's the gel-infused layer for you. It's like it reads your body and provides relief exactly where you need it, ensuring you wake up feeling refreshed and rejuvenated. This is achievable thanks to the gel foam, moulding to your body in much the same way as memory foam, but without the downsides of heat retention and movement difficulty.

1000 Pocket spring base layer

The support layer is nothing short of impressive. With 1000 individual pocket springs, it adjusts to your body weight, ensuring you can toss and turn (as we all do) without feeling trapped. And those Mirapocket® springs? They're not just there for show. They offer zoned support that's scientifically proven to improve your posture while you sleep. Ultimately pocket springs outperform open coil and reflex foam counterparts and are typically found in the more premium of ranges when it comes to what goes into a typical mattress.

Suitability for couples

For all the lovebirds out there, this mattress has got you covered regardless of whether you are looking to share intimate moments or just a regular night's sleep, the hybrid design ensures both comfort and adaptability. And if your partner is the tossing and turning type, fear not! The individual pocket springs minimise motion transfer, ensuring you sleep soundly. Plus, the gel-infused layer keeps things cool, making those warm summer nights a breeze. And let's not forget the edge-to-edge support, ensuring both of you can sprawl out without feeling like you're about to roll off.

Customer feedback

I always believe in hearing from real users, and the feedback on this mattress is overwhelmingly positive with many users having reported unparalleled comfort and support from the materials within. Back pain relief and improved sleep quality are common praises from a few long term reviews we found across the web. However, a few wished for firmer edges and a bit more support which might highlight further the unsuitability for heavier individuals and those who sleep dedicated on their back.

How much does it cost?

Quality often comes with a price tag, but the Silentnight Just Bliss Gel Hybrid Mattress is priced at £400-500 in a double. Considering the sleep experience it offers it likely offers quite good value with a premium gel layer replacing the tired and predictable memory foam layers of old.

*Assuming average weight, suitability will vary dependant on body type, use the quiz above for a more tailored guide.
  • Back Sleepers
  • 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
  • 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
  • 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.


  • Breathability
  • Mattresses that feature breathable materials help promote airflow and keep you cool making for a more hygienic night's sleep.
  • Turning on mattress
  • 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
  • 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.


  • Initial Odour
  • 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
  • Certain materials inside different mattresses can produce a small odour. Typically this is short term rather than long standing but there are minor exceptions.
