This hybrid sprung/latex mattress is the real deal. Solid yet yielding, it's an excellent buy for both back and side sleepers. Motion transfer is almost negligible so it's great if you share a bed with a restless sleeper, plus it's suitable for allergy sufferers.

Recently launched, the Silentnight Lift Replenish hybrid mattress is one of three new ranges that the Lancashire-based sleep brand launched earlier this year.
Named 'Renew', 'Rejuvenate', and 'Replenish', these new hybrid mattresses have been designed for restless sleepers. Each of the three designs has varying features, but all combine springs with latex – a variation on the usual memory foam top layer. All designs are available in four standard mattress sizes – single, double, king, and super king – with each size offering a choice of different firmness levels.
We tested the top-of-the-range Silentnight Lift Replenish hybrid mattress which boasts 2000 Mirapocket springs and a 2cm thick layer of latex on top for extra cushioning, all wrapped in what the brand calls its “Intense™ sleep surface” which promises "deeper, undisturbed sleep”.
Read on to discover how it fared in our tests, and whether we think it deserves a place on our best mattress list.

Silentnight Lift Replenish Hybrid mattress: what the brand says
The Silentnight Lift Replenish is a hybrid mattress that's made up of 2000 pocket springs topped with a latex upper layer, and wrapped in fabric cover that Silentnight call an “Intense™ sleep surface” which promises "deeper, undisturbed sleep”.
While that sounds quite jargon-y, it means that the fabric has carbon woven into it in order to reduce static electricity which builds up in our bodies naturally throughout the day. The brand says that this static can limit the production of the sleep hormone, melatonin, which helps people get better sleep. So in theory, less static = deeper sleep.
An alternative to memory foam, the latex layer is designed to add cushioning and pressure relief. Memory foam mattresses have become hugely popular in recent years, mainly due to the way that memory foam slowly contours to the body as a sleeper's body heat warms it up, offering a cocooning sleep surface moulded to your exact dimensions. A latex-topped mattress offers similar cushioning properties but can be quicker to respond as it doesn't rely on body heat to activate its elasticity. It also provides a more general contour that some prefer to the 'hug' of memory foam.
Silentnight says this latex layer is also 'Oeko-tex® approved, anti-bacterial, anti-dust mite, resistant to mould & mildew and is FR chemical treatment free, offering a cleaner, fresher sleep'.
The brand also says that those 2000 Mirapocket® springs will 'adjust to your movements throughout the night, offering exceptional tailored support that’s personal to you. Delivering the best of both; pressure relief to help ease aches and pains and offer optimal spinal alignment'.'

Our reviewer, Ginevra, slept on the Silentnight Lift Replenish Hybrid mattress for four months to test out its performance. Usually a front sleeper, Ginevra is a fan of an early night and new to a latex sleep surface having previously slept on a pocket-spring mattress. Read on to find out her and her husband's thoughts on the Silentnight Lift Replenish Hybrid mattress.
Unboxing and delivery
When the mattress arrived at my door, the delivery men took my old mattress away to recycle. They offered to bring it through our house to our bedroom (this is the standard delivery option for this mattress) but we said we could manage it ourselves.
Let me be 100% clear – this was a total fail on our part. Having never had a latex or hybrid mattress before I didn't appreciate just how heavy these beasts can be. What we didn’t realise is that a super king-sized Lift Replenish hybrid mattress weighs – wait for it – 60kg. That’s basically the same weight as a human whose dimensions measure a rather cumbersome 180x200cm.
Suffice it to say that it wasn’t easy, but my husband and I eventually managed it after several abandoned attempts. Despite it being totally our fault for saying that we could manage without their help, I do feel that the delivery men could and should have alerted us to the fact that the mattress was so heavy, but hey ho... one learns from one’s mistakes.
It's also worth bearing in mind that because of the design of the springs, this mattress can’t be rolled, folded, or squeezed into a box as that would damage the construction. This means it is absolutely not for those with loft rooms or restricted access to their bedrooms. as you simply won't get it into your room.
Once we'd hauled the beast of a mattress upstairs, we lifted it onto the bed using the handles (luckily, two each side). Once on the bed, it's really quite deep – 30.5cm to be precise – so it did feel a lot more luxe than our last sprung mattress.
The mattress was completely covered in a layer of thick plastic on delivery which we removed once on the bed. That lingering plastic smell that you sometimes get on new mattresses wasn’t present either – in fact, it smelled of very little really, which was a relief.
Unlike other brands, the mattress doesn't come with a tool to unwrap the plastic, nor did it have any instructions included, but in fairness, these usually only come with ‘mattress in a box’ style designs as they require a certain amount of settling in. In comparison, the Lift Replenish hybrid mattress is effectively ready for use pretty much right away.
How comfortable is the Silentnight Lift Replenish Hybrid mattress?
Comfort: The Silentnight Lift Replenish Hybrid comes in a choice of two firmness options; medium-soft or medium-firm. We chose the medium-firm option as our previous mattress – a wool-filled sprung model from Rest Assured – had the same firmness level, although we found the latex top layer on the Lift Replenish makes the mattress feel firmer than expected.
I previously tended to sleep on my front or side, but since sleeping on the Lift Replenish I've noticed that I don’t sleep on my front as much anymore, mainly because it’s simply not that comfortable. There is very little ‘give’ in the mattress so it’s just not possible to relax fully when lying on my stomach. As a result, I tend to favour sleeping on my side or back more now.
On the upside, an osteopath once told me off years ago for front sleeping, saying it is hands down the worst position to sleep in for one’s spine alignment, so I guess I have Silentnight to thank for my recent lifestyle change.
Meanwhile, my husband – a back sleeper – finds the mattress to be very comfortable. He too wanted me to make it clear how it was definitely more on the firm side of medium firm, but this hasn’t affected his comfort levels or his ability to sleep soundly.
Motion transfer: The lack of motion transfer is noticeably different to our previous pocket spring mattress, probably due to the 'dampening' affect of the latex upper. If either of us turn about in bed in the middle of the night, it’s barely noticeable. This proves quite useful too when our early rising 7-year-old inevitably wakes one of us up (ahem, always me) at 6am each morning.
Edge support: As mentioned, we tested a medium-firm mattress. The firmness isn't hard as such – the surface material is super soft and there’s a little bit of give when you lie down – but it does feel really quite firm.
You can see from the pictures how firm the mattress is when lying in it and the 20kg weight also shows how little the mattress dips.
Edge support is pretty solid, too. There is very little loss of firmness around the edges when you perch on the side, so if you tend to sleep on the outer edge, you’ll still be very supported.
Temperature regulation: Having always slept on a standard sprung mattress, I did have concerns beforehand that a latex mattress might have the tendency to make me overheat at night but these were quickly dispelled. The mattress felts as cool as any mattress I had slept on previously.
Extra details: Sadly this mattress doesn't feature a removable cover. This is a bit of a shame as so many mattresses these days do have the option to remove and wash their covers, meaning you can clean it as and when you choose to.
The latex beneath it does however inhibit mould growth and is naturally antibacterial, so provided you invest in a washable mattress topper, you won't know any different. All these anti-nasty qualities are an obvious bonus for allergy sufferers, too.
Final verdict: Is the Silentnight Lift Replenish Hybrid mattress worth the money?
In my opinion, the Silentnight Lift Replenish Hybrid mattress is absolutely worth the money, especially if you're able to make some savings using Silentnight discount codes.
After the initial surprise of how firm the medium-firm mattress felt, and the subsequent adjustments to my sleeping position, I know that I'm always going to have a good night's sleep on this mattress.
If you’re a back or side sleeper and you’re looking for more support as you sleep, then you would definitely benefit from welcoming the Silentnight Lift Replenish hybrid mattress into your life.
There is very little motion transfer, so if you share a bed with a restless sleeper you’ll barely notice them tossing and turning, breathability and temperature regulation are both superb, and, although I can't say for sure that the anti-static 'Intense™ sleep surface' is responsible, I have noticed that I sleep deeper when on this bed, and I don’t change position throughout the night nearly as much as I used to.
I've held back from giving the Silentnight Lift Replenish hybrid mattress full marks partly because the mattress's weight makes it a hefty one to move or rotate, plus the firmness took some getting used to. The mattress cover also isn't removable, so you can't stick it in the washing machine for a freshen-up. Small gripes but gripes nevertheless. When I revisit this review in a few months' time, I may have changed my mind.
Regardless, once you're aware of these two teeny caveats, this is still an excellent mattress that will give you night after night of undisturbed sleep.
