Construction & Materials
Let’s break down the layers that make the Silentnight Memory Cool 1000 Mirapocket Mattress special.
1. Microquilted Soft Cover
The sleep surface is a microquilted, breathable fabric. It feels smooth and soft, adding a gentle touch to your bedtime experience. The cover promotes airflow and helps the heat-dissipating foam layer beneath do its job.
2. Memory Cool™ Graphite Foam
Memory Cool™ technology is infused with graphite crystals. Graphite is known for its natural ability to absorb and dissipate excess heat. This means that sleeping hot—a common criticism of traditional memory foam—becomes less of a worry. The memory foam layer also contours to your body, cushioning the shoulders and hips.
3. 1000 Mirapocket® Zoned Springs
Below the foam are 1000 individually responsive pocket springs. These Mirapocket® springs are arranged in zones targeting key tension points, especially the lower spine. Extra support is provided just where your body needs it, while lighter pressure is applied to the head and foot zones. This helps with spinal alignment and can ease aches or pains.
4. Edge-to-Edge Support
Silentnight’s Mirapocket system gives robust support across the whole sleeping surface. You’ll benefit from extra edge support, which is ideal for couples or anyone who sleeps close to the side of the mattress.
5. Base Layer
The supportive base keeps everything stable and ensures durability for lasting use.
Comfort and Support: Who Is This Mattress Best For?
The Silentnight Memory Cool 1000 Mirapocket Mattress promises medium support with a gentle, sink-in feel. Who might benefit most?
Side Sleepers: The memory foam cushioning relieves pressure on the shoulders and hips. Zoned springs align the spine nicely in this position.
Back Sleepers: Zoned support in the lumbar region keeps your back comfortable all night. The mattress is responsive enough to avoid the hammocking effect.
Couples: The Mirapocket springs isolate movement, reducing partner disturbance—ideal if you sleep with someone who tosses and turns.
Hot Sleepers: Graphite-infused foam and a breathable cover help regulate sleeping temperature. If you’ve found other memory foams too hot, this mattress offers a cooler solution.
No-Flip Maintenance Seekers: It’s single-sided, so you only need to rotate every few months. No heavy flipping required.

Temperature Regulation: Does Memory Cool™ Work?
Traditional memory foam can trap heat, leading to uncomfortable nights. Silentnight combats this with its Memory Cool™ foam. The graphite infusion absorbs and dissipates heat, helping create a noticeably cooler sleep environment compared to regular memory foam.
Many user reviews reflect improved temperature regulation, especially for those who typically overheat. While no mattress can guarantee a completely sweat-free night if you’re a consistently hot sleeper, this one is engineered to offer genuinely cooler comfort.
Support, Pressure Relief, and Motion Transfer
The Mirapocket springs are zoned to optimise spinal alignment and pressure relief. This makes the mattress a solid choice for those with mild aches or back discomfort. The blend of memory foam and pockets springs keeps the body cushioned without excessive sinkage.
Motion isolation scores well—movement on one side is barely felt on the other. The structure also minimises roll-together, a common drawback with lower-end mattresses or all-foam beds.

Is the Silentnight Memory Cool 1000 Mirapocket Mattress Right for You?
This mattress is ideal for anyone who:
- Wants a medium-feel mattress with gentle contouring
- Sleeps hot and seeks greater airflow/cooling
- Shares a bed and needs to reduce partner disturbance
- Prefers easy care (rotate only, no flipping required)
- Trusts a major UK bed brand with strong reviews
However, those who need an ultra-firm or notably soft mattress may want to keep looking. Compare your options on our best mattresses UK page.
Comparisons with Other Silentnight Mattresses
It’s helpful to compare this model with others in the Silentnight range. For instance, the Silentnight 800 Mirapocket Mattress offers fewer pocket springs and lacks the graphite-infused cooling layer, making it more suitable for spare rooms or lighter sleepers.
The Silentnight Memory Cool 3000 Mirapocket Mattress is a step up if you desire even more advanced support and pressure relief, but comes at a higher cost.

Buying Experience & Delivery
Available at Mattress Online, the Silentnight Memory Cool 1000 Mirapocket Mattress usually arrives within 2-3 weeks of order. Delivery is included in the price. The mattress comes with a 5-year guarantee, offering extra peace of mind.
It’s delivered flat and does not come vacuum packed, so ensure you have help to manoeuvre it, especially if destined for an upper floor.
Maintenance & Care

The microquilted cover is not removable, so use a mattress protector for hygiene and longevity. Find out more about mattress protectors.
Customer Reviews: What Do UK Sleepers Say?
Customer feedback is vital when investing in a new mattress. Owners of the Silentnight Memory Cool 1000 Mirapocket Mattress frequently cite:
- Noticeable improvement in sleep temperature
- Reduced aches, especially for side and back sleepers
- Minimal disturbance from partners changing position
- Easy, low-maintenance care
- Good value, especially when on offer
A few reviewers point out that the medium feel may seem firmer at first but tends to become more body-conforming after a few weeks of use. If you’re switching from an old or sagging bed, any new mattress can take time to get used to.
Is It Good for Back Pain?
The zoned Mirapocket spring system targets lumbar support and works with the contouring memory foam to cradle your back. This can help relieve pressure and promote natural spinal alignment. While no single mattress guarantees back pain relief for everyone, the features make it a sound option to consider, especially if you want contouring with temperature control. Explore our top orthopaedic mattress picks for severe back pain.
Better Sleep for Couples
Couples often face challenges like motion transfer and rolling together in the middle. The Silentnight Memory Cool 1000 Mirapocket Mattress addresses these complaints well. Independent movement from the Mirapocket springs means you’ll sleep undisturbed even if your partner shifts at night. The sturdy edge support ensures you can both use every inch without feeling like you’re about to fall out.
Environmental and Health Considerations
The graphite-infused Memory Cool™ layer is CertiPUR compliant, free from harmful chemicals. The foams and textiles meet safety regulations for British families. And as this mattress is made in the UK, it keeps its eco footprint lower than imported beds.
How Does It Compare to Alternatives?
The hybrid design, with both pocket springs and memory foam, offers a nicely balanced feel. For those seeking even more pressure relief or a softer sleep surface, a pillow top or higher spring count might be best. Those who prefer all-foam beds should see our memory foam mattress guide for alternatives.
Alternatively, if you need higher support for a heavier build, Silentnight and others produce mattresses with 1400, 2000 or more springs.
