I’ve had this mattress for about a week now. Purchased it to replace a silent night hybrid medium-firm mattress which I found far too firm. So far, I’ve found it very comfortable and haven’t had any issues with it. I’m a side sleeper and find that it provides good comfort and support. The only kind of negative is that the springs can be felt from the sides of the mattress.

Frequently asked questions

What type of base is recommended for the Silentnight 800 Memory Pocket mattress?
For the Silentnight 800 Memory Pocket mattress, it is recommended to pair it with a compatible base to optimise its performance. A solid or slatted base can enhance the supportive features of the mattress and ensure it maintains its shape over time. Using the right foundation helps to maximise the benefits of the Mirapocket spring system and memory foam, delivering a better sleep experience.
What benefits does the Mirapocket 800 spring system provide?
The Mirapocket 800 spring system features 800 individual springs that move independently, offering personalised comfort and support. This design helps to relieve pressure points and encourages healthy spinal alignment. It also reduces motion transfer, so if you share your bed, you're less likely to be disturbed by your partner's movements.
What kind of foam is incorporated in this mattress?
The mattress includes memory foam that adapts to your body contours, helping to alleviate pressure points for a restful sleep experience.
How does the pocket spring system work in this mattress?
The mattress has a pocket spring system where each spring is housed in its own fabric pocket. This allows the springs to move independently, which helps the mattress mould to your body shape and reduces motion transfer.
What type of finish can I expect on this mattress?
This mattress features a micro quilted finish, achieved by stitching the fabric and fillings together. This process creates a patterned comfort quilt layer that enhances softness for a more comfortable sleeping experience.
Does the mattress have handles to help with moving it?
Yes, the mattress has handles on the sides. These make it easier to rotate and turn when you need to.
Can this mattress accommodate every type of sleeping position?
The 800 Memory Pocket mattress features a combination of pressure-relieving memory foam and a pocket spring system, making it suitable for providing both support and comfort regardless of how you sleep.
What is the flammability rating of the mattress?
This mattress has a Source 2 flammability rating. This means it meets the low hazard criteria for normal household use.
How does the temperature-regulating feature of the memory foam work?
The temperature-regulating feature of the memory foam ensures that the mattress remains breathable and helps to dissipate heat as you sleep. This means that it can actively keep you cool throughout the night, preventing overheating that might disrupt your sleep. As a result, you can enjoy a deeper, uninterrupted rest, regardless of the ambient temperature.
How often should I rotate the mattress for optimal care?
While the mattress does not need to be turned, it is advisable to rotate it every few months to ensure even wear and maintain its comfort.

60-night sleep trial: exchanges only, not refunds. Activated by purchasing a mattress protector at the point of order. Request your exchange between nights 30 and 60 of the trial; a £50 exchange fee applies. Full terms.
