The Silentnight SleepResponse Relieve 3000 is a relatively new addition to the Silentnight range, sold exclusively through Dreams. On paper you are getting a good number of springs, a deeper box-top comfort layer and a cooling cover for a fairly punchy
ticket price that places it in premium territory.
In reality, the story is a little more complicated. The Relieve 3000 is very comfortable, supportive and demonstrably cooler than old-style memory foam, but its overall feel is not miles away from the cheaper Relieve 2000 model that sits just below it
in the same range. Unless you particularly want that slightly deeper, more cushioned top, the 2000-spring variant is likely to represent better value for most people.
Construction & materials
Silentnight describes the Relieve 3000 as a combination mattress, which in this case means a pocket-sprung core paired with a latex comfort system and a plush box top.
At the heart of the mattress is Silentnight’s Mirapocket zoned support unit. These are individually wrapped pocket springs arranged in zones of differing tension, designed to give a little more resistance around the hips and lumbar region and a touch
more give around the shoulders. That zoning is what helps keep your spine more neutrally aligned rather than letting heavier areas sink too far.
Above the springs sits a layer of breathable latex. Latex behaves quite differently to standard memory foam. It compresses readily under pressure but bounces back almost instantly, so you do not get that slow, “stuck in the mud” feeling. It is also naturally
perforated and more open in structure, which helps air circulate through the mattress.
The “3000” in the name refers to the quoted spring count. In practice, this is usually achieved by combining a conventional pocket-spring core with a thinner micro-spring layer closer to the surface. Those mini springs add a little extra compliance and
marketing appeal, but they are not transformative on their own, and I would avoid putting too much weight on the headline number. The basic Mirapocket core is doing the bulk of the work.
On top of everything you get a generously filled box top, wrapped in Silentnight’s CoolEase fabric. A box top is essentially a permanently attached mini-mattress stitched to the main body, and here it gives the Relieve 3000 a plusher, more cushioned first
impression compared with the tufted, flatter surface of the Relieve 2000. Internally this box top combines soft fibres and foam around the latex layer to round off the feel.
As with most hybrids at this price point, the mattress is single-sided, so it is designed to be rotated head-to-toe rather than flipped. There are handles on the sides to help with manoeuvring, and the overall build feels reassuringly solid and weighty.
Firmness & feel
I would class the SleepResponse Relieve 3000 as sitting on the firmer side of medium. The initial sensation when you lie down is one of softness from the box top, followed quite quickly by firmer pushback from the zoned spring unit underneath.
The latex layer is key to the feel here. It compresses cleanly under bony areas like shoulders and hips, which stops the mattress feeling unforgiving, but it rebounds fast enough that you never sink in as deeply as you would with a thick layer of traditional
memory foam. That gives the surface a slightly buoyant, lifted quality rather than a deep hug.
Side sleepers of average build should find there is enough give in the top to prevent sharp pressure on the shoulder, especially if you use a reasonably supportive pillow to keep your neck in line. Back sleepers, meanwhile, get a nicely even contact across
the whole back, with the zoned Mirapocket core helping to stop the lower back from dipping.
Front sleepers are usually better served by a genuinely firm mattress, but lighter stomach sleepers should still be reasonably well supported here, as the latex does not collapse in the way softer foams can. Much heavier sleepers, or anyone who unapologetically
prefers a very firm, board-like feel, may find the top a touch too cushioned.
Crucially, the overall character is not wildly different from the Relieve 2000. The 3000’s box top introduces a slightly deeper, plusher comfort layer, but the underlying response, zoning and general level of firmness feel very similar. It is more of
a refinement than a reinvention.
Performance & support
Spinal alignment
The Mirapocket zoned system does a decent job of keeping the spine in a neutral position, particularly for back and side sleepers. The hips are prevented from sinking too far, while the latex allows shoulders and smaller joints to nestle in enough to
avoid over-arching through the mid-back.
Pressure relief
Pressure relief is generally good, especially across the shoulders and outer hip when side sleeping. The latex spreads load over a wider area than a simple fibre quilt, and the box top stops you feeling the structure of the springs beneath. If you are
extremely pressure-sensitive, or you like a truly marshmallow-soft top, you may still want to add a separate topper, but for most people it should be comfortable enough out of the box.
Edge support
Edge support feels adequate rather than class-leading. You can sit on the side to tie your shoes without immediately sliding off, but there is a little more give than on some reinforced-edge hybrids. Sleeping right up to the edge is fine, though couples
who routinely use every centimetre of the mattress might notice the perimeter softening slightly faster over time than the centre.
Motion transfer
The combination of pocket springs and latex deals with partner movement fairly well. Pocket springs are already better than open-coil in this respect, and latex, while more responsive than memory foam, still absorbs a fair bit of energy. You will feel
larger movements such as someone getting in or out of bed, but smaller position shifts are nicely muted.
Durability
The materials chosen, particularly latex and a zoned pocket unit, are generally a positive sign for long-term performance. Latex tends to hold its resilience for longer than basic polyurethane foams, and pocket springs resist sagging better than simple
open-coil units. That said, the plush box top is where you are most likely to see body impressions over time, especially in lighter fibre-rich sections, so regular rotation is important.
Temperature regulation
Temperature is one of the Relieve 3000’s main selling points. The mattress uses a combination of breathable latex and a CoolEase cover designed to draw heat away from the body. Compared with a thick slab of traditional, closed-cell memory foam, it does
feel noticeably fresher and less clammy, particularly on warmer nights or if you tend to run hot.
Latex is naturally more open and springy, so it does not envelop you in quite the same way as dense memory foam, and air can circulate more freely between the springs, latex and fibre layers. The fabric itself has a cool-to-the-touch character when you
first lie down, which gives an immediate sense of relief if you often overheat.
However, I would be a little cautious about assuming this is dramatically cooler than every other “cooling” option out there. Gel-infused foams and other advanced comfort layers are already well established in the market, and much of the difference comes
down to overall layering, cover fabric and bedroom environment rather than one magic ingredient. The cooling story here is credible and beneficial, but it is still a padded, fairly deep mattress, not an air-conditioned slab.
Practical features
Sizes and profile
The Relieve 3000 is available from single up to super king, so it will work in most UK bedrooms. It has a substantial profile, thanks to that box top, and looks suitably luxurious on the right bed frame. If you are upgrading from a slim mattress, you
may find your fitted sheets a little snug, so it is worth checking the depth and making sure your bedding is up to the job.
Weight and handling
With its spring core and latex comfort layers, the Relieve 3000 is a heavy mattress, especially in the larger sizes. Silentnight provides handles around the sides, but rotating it will realistically be a two-person job. The upside is a feeling of solidity
on the bed; the downside is that regular maintenance is more of a faff.
Care and maintenance
This is a single-sided, no-turn mattress, so you only need to rotate it head-to-toe, weekly for the first three months and then every month after, to help keep settlement even. As with any plush-topped design, you may see some light body impressions forming in the upper layers over time, but weekly
rotation in the first three months will help minimise this.
Retailer extras
Buying through Dreams brings the usual practical perks, including free delivery to your door on qualifying orders and the option of a comfort-guarantee-style period, plus recycling of your old mattress for an additional fee. Those services do improve
the overall ownership experience and are worth factoring into the value equation alongside the headline price.
Who it suits
Side and back sleepers who like a cushioned top
If you prefer a mattress that feels plush at the surface but still keeps you lifted and aligned underneath, the Relieve 3000’s combination of a soft box top over a firmer, zoned core will appeal. It offers a good compromise between pressure relief and
structure.
Hot sleepers who dislike dense memory foam
Those who find standard memory foam too hot and enveloping should get on well with the latex and CoolEase cover. You still get that “cradled” sensation, but with a fresher, more breathable feel and less of the slow, sinking response.
Couples with different sleeping positions
The middle-of-the-road, slightly-firm-medium feel and respectable motion isolation make this a sensible compromise for couples where one partner sleeps on their side and the other prefers their back. Both are likely to find enough support without either
feeling the mattress is wildly wrong for them.
Anyone who values a deeper, more luxurious-looking mattress
The box-top design gives the Relieve 3000 a hotel-style look on the bed, and if aesthetics matter to you as much as feel, this does help justify some of the extra outlay over plainer models.
Who it does not suit
Shoppers who prioritise value over marginal gains
If value for money is your primary concern, the step up from the SleepResponse Relieve 2000 to the Relieve 3000 is not as dramatic as the model names and spring counts might suggest. The core support and general feel are very similar, and the extra micro
springs mainly serve to bump up the figures on the spec sheet. Unless you specifically want that slightly deeper, more cushioned comfort layer, the 2000-spring variant is likely to be the better all-round choice.
Fans of ultra-firm mattresses
Those who like a truly rigid, orthopaedic-feeling bed will probably find the plush box top and latex too forgiving. There is sound support underneath, but the top does have a definite level of softness that you cannot avoid.
Very heavy sleepers needing maximum support
While the zoned Mirapocket core is capable, very heavy sleepers or people with significant back issues may be better served by a firmer, more explicitly orthopaedic design without such a thick comfort layer. The Relieve 3000 aims to balance comfort and
support rather than push hard towards one extreme.
Buyers who are sceptical of high spring counts
If you are already wary of marketing-friendly spring numbers, the “3000” badge here is unlikely to win you over. The mattress performs well enough on its own merits, but the micro-spring element does not radically change the feel compared with the simpler
2000-spring construction.
Final verdict
The Silentnight SleepResponse Relieve 3000 Combination Mattress is a well-made, comfortable latex hybrid with a genuinely pleasant balance of cushioning and support. The Mirapocket zoned core does what it is supposed to, the latex layer brings responsive
pressure relief, and the CoolEase cover and breathable construction keep things appreciably cooler than a lot of traditional memory foam rivals.
Where it is harder to be enthusiastic is on value. The jump from the Relieve 2000 to the 3000 is mainly about a plusher box top and an inflated spring count that, in practice, does not dramatically alter the underlying feel. For some, that extra bit of
surface luxury will be worth paying for, especially in a main bedroom where the mattress is on show and comfort is king.
For many others, though, the Relieve 2000 will likely be the smarter buy, delivering much of the same support story and latex comfort at a noticeably lower price. If you are torn between the two and do not have a strong pull towards a deeper, more pillowy
top, I would be inclined to steer you towards the 2000 and put the savings into quality pillows and bedding instead.
In short, the SleepResponse Relieve 3000 is a solid, cool-feeling mattress that will suit a lot of sleepers very well, but its premium is best justified by those who are happy to spend extra for a slightly more indulgent sleeping surface rather than expecting
a night-and-day difference in support.
