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.
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.
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.
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.
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.
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.
Vegan-friendly
Plant-based or synthetic fillings avoid wool, silk or other animal-derived fibres, leaving the surface suitable for shoppers avoiding animal materials. Check cover materials and fire barrier details where allergies are involved.
Approved by the National Bed Federation
Factory auditing checks that the mattress is made under UK rules for flammability, fillings and labelling, giving you a clearer paper trail for what arrives at home. It doesn't prove comfort, firmness or long-term durability.
5 year guarantee
Fault cover puts manufacturing problems in writing, making a loose strut, failed fixing or collapsed padding less of a gamble after delivery. Accidental damage, fabric marks and poor fitting usually sit outside it.
Hypoallergenic for your peace of mind
Lower-irritant cover materials are intended to give dust mites and everyday allergens fewer places to settle, which may suit you if your nose or skin reacts easily. Allergy sufferers may need a washable protector.
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.
Mirapocket springs
Pocketed coils compress separately, giving your hips and shoulders more local give. Because each coil moves on its own, cheaper builds can lack edge firmness and may feel busy under very restless sleepers.
Pressure relief
Softer comfort layers let shoulders and hips sink slightly into the surface, spreading body weight before you feel sharper points building. Front sleepers may want firmer support to keep the hips level.
Handmade in the UK
A headboard made in the UK ensures meticulous craftsmanship and attention to detail. Handmade options may incur higher costs compared to mass-produced alternatives, which could affect your budget.
Memory Foam
Foam in the comfort layer softens under body heat, letting shoulders and hips sink closer into the surface while reducing sharp pressure points. It can feel warmer and slower to move on.
Handcrafted in the UK
Factory workers assemble and finish the mattress by hand, leaving small variations in stitching or edge detail you may notice up close. It doesn't prove better support or longer life.
Single-sided
Bed-making is simpler because the comfort layers stay on the top face, leaving the underside to stabilise the mattress while you lie on the cushioned surface. Don't flip it over.
Depth: 26cm
Mattress height changes how far you climb into bed, while a 26cm body can look substantial on a lower frame. Shallow fitted sheets may strain at the corners.
