The Silentnight Sleep Response™ Relieve 3000 Combination Mattress is a UK-made, Dreams-exclusive hybrid that leans heavily into two things most shoppers care about, staying cooler through the night and feeling well-supported without tipping into “board-like” firmness. On paper it is a medium-tension design built around zoned Mirapocket® springs, with latex and micro springs adding extra responsiveness, plus a box top for a deeper, plusher first impression. A 100-night comfort guarantee and 5-year guarantee help make it feel like a lower-risk purchase in a premium bracket.
Construction & materials
This mattress uses a spring-led build rather than being foam-heavy, which usually suits sleepers who want bounce, easier movement, and less of the “stuck-in” sensation.
- Responsive pocket springs, described as a Mirapocket® zoned support system for targeted support and improved spinal alignment.
- Adaptive micro springs designed to respond to smaller movements, typically adding a more nuanced, reactive feel on top of the main spring unit.
- Breathable latex filling for pressure relief with a naturally springy, more temperature-neutral feel than traditional memory foam.
- Premium box top design intended to create a deeper, more luxurious surface.
- CoolEase cover, described as drawing heat away from the body.
- Single-sided construction, so it is designed to be rotated rather than flipped.
Comfort, firmness & feel
Silentnight rates it as medium, which tends to land in the “cushioned but not sinky” camp. Between the box top, latex and micro springs, the feel should be responsive and lightly buoyant, with give where the body is heaviest rather than a slow-melting memory foam hug. Shoppers who like to change position easily, or who dislike deep contouring, are more likely to get on with this style of comfort.
Support & pressure relief
The zoned Mirapocket® system is presented as being scientifically proven to improve spinal alignment and posture, which suggests a design that aims to hold the midsection more steadily while letting shoulders and hips settle appropriately. Latex is a good fit here because it cushions without collapsing, so it can reduce pressure build-up while still keeping the body feeling “on” the mattress rather than in it.
Motion isolation
There is a clear intention to reduce partner disturbance. The customer feedback specifically mentions reduced motion transfer, and individually wrapped pocket springs generally help here because movement is contained within each spring rather than rippling across a whole unit. That said, the addition of micro springs and an overall responsive build can still feel a touch livelier than an all-foam mattress, so ultra-light sleepers may not find it as deadened as dense memory foam.
Temperature regulation
Cooling is a main selling point. The CoolEase cover is designed to pull heat away from the body, and latex is naturally more breathable than many foams. A spring-based interior also tends to allow more airflow than solid foam blocks, so taken together, the Relieve 3000 looks well-specified for people who regularly wake up too warm.
Edge support
Edge support is not confirmed in the provided specifications or reviews. The box top can sometimes soften the very perimeter feel when sitting, even if the underlying spring unit is supportive, so shoppers who rely on a very firm edge would ideally confirm this detail with the retailer’s guidance or further customer feedback.
Practicalities (cover, maintenance, guarantees)
- 100 Night Comfort Guarantee, which gives a meaningful window to decide if the medium feel suits real-life sleep.
- 5-year guarantee is stated in the customer feedback.
- Single-sided design should simplify upkeep, as it does not require flipping, only routine rotation.
- Made in the UK, with recycled materials mentioned in the customer feedback, which will appeal to shoppers prioritising sustainability.
Who it suits
- Side sleepers wanting a medium feel with pressure relief, particularly around shoulders and hips.
- Combination sleepers who value an easy-to-move-on surface, helped by latex and spring responsiveness.
- Hot sleepers who want more active temperature management through the cover and breathable internal materials.
- Couples looking for a balance of spring support with motion transfer reduction.
Who it does not suit
- Fans of deep, slow “memory foam sink”, as latex and micro springs generally feel bouncier and more immediate.
- Back sleepers who strongly prefer a firmer, flatter feel for maximum lumbar “hold”, as this is clearly positioned as medium rather than firm.
- Anyone who needs confirmed, standout edge support, as this is not evidenced in the supplied information.
What customers liked
- Cooling performance, with the cover specifically called out for helping prevent overheating.
- Support and spinal alignment focus, attributed to the Mirapocket® spring system.
- Reduced motion transfer, suggesting fewer disturbances from a partner’s movement.
- The luxurious feel of the box top design.
- Easy maintenance due to single-sided construction.
- UK-made credentials and the use of recycled materials were highlighted as a positive.
What customers disliked
There is not enough genuine review detail provided to report meaningful negatives without guessing.
Final verdict
The Silentnight Sleep Response™ Relieve 3000 Combination Mattress reads like a well-judged premium hybrid for shoppers who want a medium, cooler-sleeping mattress with a responsive, gently cushioned surface. The combination of zoned pocket springs, latex, micro springs and a box top should suit side sleepers especially well, while still offering enough structure for many back sleepers who do not need a firmer feel. Those chasing the deepest motion-deadening foam feel, or those who require confirmed edge stability, may want more supporting evidence before committing, but for balanced comfort with a strong cooling brief, it is a compelling option backed by a 100-night comfort guarantee.
