About the Silentnight Memory 800 Mirapocket Mattress
Last checked
An 800 Mirapocket spring unit sits under memory foam, soft white fibres and a microquilted surface that also uses Reflex foam, giving this 24cm Silentnight a straightforward pocket-sprung-with-foam construction rather than a deep hybrid build. With a firm, 5 of 5 feel, the centre-third zoning is the important support detail: it should resist sagging more through the torso than a basic open-coil mattress, while the individual pockets respond more independently than a linked spring cage. That is a sensible but restrained build. An 800-spring count is fair for a mainstream firm mattress, but it is conservative beside the 1000-plus pocket units common in the mid-range pocket-sprung tier, so the comfort relies heavily on the memory foam and fibre stack rather than sheer spring density. The pressure-relief claim has a real material basis because memory foam spreads load around hips and shoulders, yet the soft white fibres and knitted cover are there to keep the surface from feeling too dense or clammy. Single-sided care is convenient: rotation replaces flipping, and the 5-year guarantee is normal for this class.
Memory foam over a zoned firm spring core suits back sleepers and some front sleepers who want a flatter, steadier feel, and the stronger praise tends to centre on comfort, value and the mix of cushioning with support. The 4.6-star average across 301 reviews is supported by repeated mentions of easier sleep, with one scoliosis-related purchase described as a marked comfort improvement, and the knitted cover plus fibre layers line up with comments about the mattress feeling cooler than expected. Heat is still a live issue for foam: the longest owner feedback describes a wrapped, sink-in feel that becomes warm at night, so hot sleepers should treat the breathable cover as a moderating feature, not a cure for memory-foam warmth. Edge support is the caution here. Although the specification highlights a rod-edge border to reduce roll-off, poorer feedback specifically flags sinking at the sides and disappointment with support, including hip and leg soreness from a side sleeper; that contradicts the neat pressure-relief message and matters most for people who sleep close to the edge or need softer shoulder give. It lands best in a main or spare room for someone wanting a firm memory-foam pocket mattress without stepping up to the £700-plus pocket-sprung tier; side sleepers with sensitive hips, or couples who depend on a very secure perimeter, may need to compare deeper hybrids or higher spring-count pocket mattresses first.

Specifications
Manufacturer specifications without the jargon, easy to scan and compare.
5 year guarantee
A 5 year guarantee is longer than the industry standard and gives confidence that both the supplier and retailer have confidence in the product they sell. After all, if it goes wrong through a manufacturing defect in this time, they will be the ones on the hook! Sleep soundly with the confidence that you will not be left out of pocket through this period. A win for the consumer.
Vegan-friendly
Heralding a compassionate step towards lifestyle compatibility, a vegan-friendly attribute implies the absence of animal-derived elements, a prominent feature savored by the environmentally-conscious folks. With a likely negative for allergy sufferers due to the potential inclusion of synthetic materials, it's debatable whether this facet should be an ultimate decisive factor.
24cm deep
Featuring a substantial depth of 24cm, this mattress provides ample cushioning and support, catering to varying sleep preferences with its luxuriously cozy yet supportive feel. The enhanced depth also suggests a higher level of material build, implying improved durability and longevity, encouraging an extended mattress lifespan that's a beneficial investment for the long run.
Depth: 26cm
Impressively deep at 26cm, this specification is suggestive of a more luxurious sleep surface, potentially providing greater comfort and support due to the possible inclusion of additional layers. However, it may require deeper fitted sheets, which could be an additional consideration for potential buyers when thinking about overall ease of use and maintenance.
Medium to Firm
Brandishing a "medium to firm" categorisation, this refers to the desired balance between support and comfort. Typically, such a rating means you'll experience an optimal distribution of your body weight while ensuring pressure points like hips and shoulders won't sink too deeply, thereby resisting counterproductive sagging and promoting aligned posture.
Knitted cover
A knitted cover spells out a blend of cosiness with breathability, providing a comforting touch that many crave while ensuring your temperature remains well regulated throughout the night. This feature pairs comfort and functionality in a coveted balance, contributing to an intimate sleep environment that is warm, inviting, yet refreshingly aerated.
Hypoallergenic for your peace of mind
Hypoallergenic materials, as indicated by the specification, cater to those with sensitive skin or allergies, reducing the risk of unwanted reactions and ensuring a comfortable sleep. Additionally, it signifies an investment in health-conscious choices, promoting an environment less conductive to the growth of bacteria and dust mites.
Approved by the National Bed Federation
The independent seal of approval from the National Bed Federation assures meticulous standards of manufacturing. With a rigorous assessment of quality, durability and safety, such an endorsement means you're getting a product that meets top-class industry standards, contributing to more sound and relaxed slumbers.
Fire Resistant
Ensuring safety during your peaceful slumber, fire resistance is a crucial feature that reduces the risk posed by potential accidents involving flammable materials. Furthermore, it demonstrates the manufacturer's commitment to adhere to strict safety standards, prioritizing your well-being over all else.
Mirapocket springs
Mirapocket springs deliver an edge-to-edge support by allocating weight individually, hence, ensuring exceptional personalised comfort and less partner disturbance during sleep. However, potential over-firmness in smaller size mattresses might not be ideal for those who prefer a softer sleeping surface.
National Bed Federation Approved Brand
Receiving approval from the National Bed Federation indicates that the product meets specific industry standards and quality benchmarks. This approval serves as a reassurance of the product's reliability and durability, though discerning buyers may still want to consider personal comfort preferences.
Memory Foam
A mattress featuring memory foam guarantees body-conforming comfort, as the material adapts to your unique shape, cradling you for personalized support. However, for individuals who tend to sleep hot, heat retention could be an issue due to the foam's dense cellular structure which traps body heat.
Pressure relief
Experience the thrill of undisturbed slumber by utilizing the pressure relief feature in your new mattress. This distinctive trait focuses on diminishing pressure points throughout your body, distributing weight evenly and providing a tailor-made sleeping experience resembling zero gravity.
26cm deep
A mattress with a depth of 26cm assures a medium-thick construction, offering a harmonious blend of support and comfort. Consequently, sleepers can anticipate a balance between plush comfort layers and robust supporting springs or cores, without any compromise on overall longevity.
Soft White Fibres
Incorporating soft white fibres into the design equates to enhanced breathability and temperature regulation within the sleep surface. This, in turn, contributes to a sleeping environment that stays fresh and cool, promoting a more restful and comfortable night's slumber.
Firm
Firmness in a mattress indicates robust support for your spine, reducing the risk of back pain and contributing favourably to your posture. Still, it might not be suitable for those who prefer a softer surface or side sleepers, who could find such solidity uncomfortable.
Hypoallergenic
Hypoallergenic mattresses are the perfect choice for those with allergies or sensitivities, as they protect against allergens and irritants. They're also a great choice for those with asthma or respiratory issues.
Handcrafted in the UK
Wow! If you're looking for a high-quality mattress that is handmade in the UK, then this is one to watch. This mattress is made with high-quality materials and tested to ensure quality.
