It can be tough to decide.

Pros and Cons

Sleepers praise the noticeably comfortable feel, delivering the kind of ease you’d expect when you first lie down.
Customers highlight the overall quality, describing it as a dependable, well-made choice.
Buyers appreciate that it meets expectations for a premium mattress without any unpleasant surprises.
Reviewers note a satisfying balance of comfort and support that feels “right” from the outset.
Shoppers also mention a smooth purchasing experience, giving credit to the retailer’s reliable service.

The “sink-in” memory foam feel can make it harder to change position, which may frustrate restless sleepers or those with mobility/joint stiffness.
With only 1000 pocket springs (king size) and a medium-firm build, heavier sleepers may find it doesn’t offer quite enough deep support or longevity compared with higher-count, firmer hybrids.
Although cooler than standard memory foam, it can still retain some warmth for very hot sleepers—especially in warmer bedrooms or for those who naturally run hot.

Our Thoughts On The Silentnight Memory Cool 1000 Mirapocket Mattress

If you're in the market for a new mattress, the Silentnight Memory Cool 1000 Mirapocket Mattress is likely worth your consideration. Known for combining comfort with cooling technology, this mattress aims to deliver a more restful sleep experience by effectively supporting and aligning the body while reducing heat retention. But what exactly sets it apart, and does it stand up to the promises it makes? Let's dive into the specifics and performance of this intriguing mattress choice.

Comfort and Support

The Silentnight Memory Cool 1000 Mirapocket Mattress is renowned for its balance between cushioning and support, featuring 1000 individually pocketed Mirapocket springs that offer zoned support tailored to your body. This zoned design is scientifically proven to promote spinal alignment, particularly targeting the lower back, which can ease aches and encourage a restful night’s sleep. The medium-firm tension of the mattress is designed to equally accommodate side and back sleepers, making it a versatile option for those of average weight. However, side sleepers with more pronounced curves might consider a slightly softer tension for additional sinkage.

Cooling Technology

What truly distinguishes the Silentnight Memory Cool 1000 is its innovative Memory Cool™ foam, which is infused with graphite particles to enhance thermal regulation. As you settle into the foam, these particles work together to absorb and dissipate body heat, maintaining a sleep environment that's 15% cooler than standard memory foam. This feature makes it an excellent choice for those who tend to overheat at night, providing a cooler, more comfortable sleep.

A Breathable Design

Enhancing its cooling capabilities, the mattress includes a breathable border with a 3D knit structure. This allows air to circulate more freely, helping to release heat and moisture during the night. Such design elements contribute not only to a cooler mattress surface but also to a fresher sleeping environment overall.

Customer Experiences

Customer feedback highlights Silentnight's reputation for quality and comfort. Users have praised the mattress for delivering what one expects from a high-quality product, with comments such as "Comfortable and what you expect from a quality product." While many have appreciated the cooler sleep environment and minimal partner disturbance, some potential users, particularly those with specific side-sleeping needs, might find the medium-firm tension less ideal if seeking more sinkage.

What Customers Thought

Many describe the mattress as providing excellent comfort and support.
The cooling foam layer is especially appreciated by those who tend to sleep hot.
Some have noted the medium-firm feel is perfect for both back and side sleepers.
There is satisfaction with its construction quality, translating to a durable mattress.
Critiques include a few customers suggesting the mattress may be too firm for those preferring softer support.

Final Thoughts

The Silentnight Memory Cool 1000 Mirapocket Mattress delivers on its promise to offer a cooler, comfortable sleep with its innovative graphite-infused Memory Cool™ foam and zoned Mirapocket springs. It may not be the perfect choice for everyone, particularly for side sleepers who require more plush support. Still, its combined elements of cooling, support, and durability present it as a strong contender in the luxury mattress market, and it rightly earns its status as a trusted product from one of the most reputable brands in the UK.

Empirical Data Of Silentnight Memory Cool 1000 Mirapocket Mattress

We have took a deep dive into the specifications and customer reviews to bring the below dataset. Be advised that the modelling assumes average weight and so suitability may vary.

Suitability

Back Sleepers

For back sleepers, the level of support a mattress provides is influenced by its firmness and the type of support layer used, with considerations tailored to those of an average build to ensure proper spinal alignment and comfort.

Suitability

Side Sleepers

For side sleepers, it’s important to have a mattress with a supportive tension that strikes the right balance—neither too firm nor too soft. This ensures the hips and shoulders can sink adequately, promoting proper spinal alignment and overall comfort.

Suitability

Stomach Sleepers

For stomach sleepers, a mattress should provide a firm and supportive base layer to offer adequate body contouring and prevent aches and pains. The level of support needed may vary depending on your body type and build.

Performance

Breathability

Mattresses designed with breathable materials enhance airflow, allowing heat to dissipate and helping to regulate your body temperature throughout the night. This not only keeps you comfortable but also provides a hygienic sleeping environment.

Performance

Turning on mattress

Some materials, such as memory foam, can make it harder to move or reposition yourself as you sleep, due to their contouring nature. Similarly, pillow-top designs, while offering a plush feel, can reduce movement making turning more challenging.

Performance

Stability

Stability is influenced by the type of support layer used, affecting edge-to-edge support and the prevention of roll-together. For instance, pocket springs with a firmer tension typically offer greater stability compared to softer open coil designs.

Odour

Reduced Initial Odour

Some mattresses, especially those made with memory foam or delivered as rolled bed-in-a-box options, may have a noticeable smell when first unpacked. This initial odour usually fades significantly within 24 hours as the materials air out.

Odour

Reduced Standing Odour

In some mattresses, certain material compositions can lead to a longer-lasting odour that may persist beyond the typical airing-out period. This is more common in products with dense foams or certain adhesives, but proper ventilation can help reduce the scent over time.

Reasons To Buy

Specifications without the jargon, easy to understand and digest.

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.

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.

Reflex Foam

Reflex foam, characterised by its solid and supportive nature, aids in even weight distribution, thus minimising pressure points and improving your body alignment during sleep. However, it's worth noting, this type of foam tends to retain heat, which may not be optimal for those who prefer cooler sleeping environments.

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.

Reinforced mattress edge

A reinforced edge signifies a mattress feature where the borders have been fortified, adding a firmness to the perimeter. This enhancement not only provides bolstered support, but also prevents premature sagging, and in turn amplifies the durability and longevity of your sleep surface.

Microquilted

Microquilting provides a smoother and more durable finish to the mattress surface, enhancing comfort and longevity. This construction method helps maintain the mattress's shape and resilience over time, contributing to a consistent and supportive sleep experience.

29cm deep

An impressive depth of 29cm signals a robust build and room for elements of luxurious comfort. Nonetheless, it might require deeper fitted sheets, slightly escalating your bedding costs.

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.
