Dynamic Support layer
Is an innovative foam layer that gives just the right amount of bounce and enhances airflow, regulating your body temperature, keeping you at a comfortable temperature all night long.

Cooling, Cushioning Simbatex® Foam

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.

Pressure Relieving Memory Foam
Provides support and comfort where you need it most.

Honeycomb Micro-Zoned Transition layer and Honeycomb Micro-Zoned Support Base
These precision engineered layers work in harmony to make micro-adjustments and optimise spinal alignment.

Zoned, high density foam base
A notch-cut, high-density foam base provides zoned pressure relief to your body, with specific zones for the shoulders and hips and other potential problem areas.

Tencel® Outer Cover
This outer cover provides a luxurious, natural and breathable surface which can be removed and machine washed whenever you wish (machine wash at 30°C). Tencel® is naturally anti-bacterial, moisture-wicking, and sustainable. The breathability outperforms natural cotton and even the most hi-tech synthetics. It is also supremely strong and durable, yet luxuriously silky and soft to the touch. Vented 3D mesh panels at each end aid in preventing heat retention.

Protective Inner Cover
This micro-fine inner cover protects all the foam layers.

A polyester-blend cover that uses novel heat-wicking and cooling technology, this super soft cover helps to regulate your temperature when you sleep.
