Visco-Elastic Memory Foam This high density open-cell memory foam disperses heat more efficiently than previous generation memory foam. Cool-Sleep Airflow Layer The upside-down egg carton-like design, built with temperature-regulation in mind, is a unique airflow system that encourages air to freely circulate thorough the mattress keeping you cool while you sleep. | The Silentnight Eco Comfort Pocket 1200 Mattress prioritizes breathability to deliver a consistently comfortable sleeping environment. Its advanced Eco Comfort Fibres are specially designed to enhance airflow, allowing for better temperature regulation throughout the night. These fibres create a naturally ventilated surface that actively disperses heat, helping to prevent overheating—a common issue for many sleepers. Moreover, the fibres wick away moisture, maintaining a clean, fresh, and dry sleeping surface.
This breathability makes the mattress an excellent choice for all seasons. It stays cool during warm summer nights while retaining just the right amount of warmth for a cozy winter's sleep. The Eco Comfort Fibres are also hypoallergenic, reducing allergens to promote a healthier sleep environment. Silentnight’s thoughtful design ensures that the mattress is not only supportive but also contributes to overall well-being, making it ideal for those who value comfort and a fresher night’s sleep.
Key Features of Comfort Specs:
* Enhanced ventilation through breathable Eco Comfort Fibres™.
* Moisture-wicking materials for a clean and dry sleep surface.
* Excellent temperature regulation for year-round comfort.
* Hypoallergenic properties to reduce allergens and promote healthier sleep.
* Long-lasting comfort and support for a fresh sleep experience over time. |
Support Specs | |
Visco-Elastic Memory Foam A generous top layer of 9cm of true high-density visco-elastic memory foam provides supportive body-shaping performance. With billions of spherical shaped open cells, that intelligently respond under your weight to create the optimum level of body-cradling support to alleviate pressure points (such as the lower back, hips, shoulders). High-Resilience Foam Base Nine centimetres deep, this high resilience impact-resistant foundation layer ensures perfectly weighted support for the upper layers. It provides class-leading performance and longevity. | The Silentnight Eco Comfort Pocket 1200 Mattress features an advanced 1200 Mirapocket spring system designed to provide personalized support. Each spring operates independently, adjusting to your body’s weight and contours to offer unparalleled comfort. This design ensures that pressure is evenly distributed, reducing strain on key areas such as the shoulders, hips, and lower back. By targeting these pressure points, the mattress promotes proper spinal alignment, which is essential for minimizing aches and maintaining good posture.
The spring system is zoned, meaning that different sections of the mattress are engineered to provide varying levels of support where it’s needed most. This feature makes it suitable for all sleeping positions—whether you sleep on your back, side, or stomach. Additionally, the Mirapocket system excels in motion isolation, making it perfect for couples by preventing movement transfer. With Silentnight’s focus on durability, the springs are built to maintain their supportive properties over time.
Key Features of Support Specs:
* Individually pocketed springs for tailored body support.
* Zoned design to relieve pressure on shoulders, hips, and lower back.
* Promotes spinal alignment for improved posture and reduced discomfort.
* Exceptional motion isolation to minimize partner disturbances.
* Long-lasting support system designed for durability and consistent comfort. |
