Engineered to extend deep sleep phases

Emma's ingenious Diamond Degree® Graphite Foam offers a refreshing sleep like no other. Scientifically engineered to enhance your deep sleep stages by lowering your core body temperature, this foam cleverly absorbs heat and moisture, offering the optimal sleeping climate.

Personalised pressure relief

A layer of adaptable HRX Comfort Foam also contours to the unique curvature of your body, providing maximum pressure relief. Gently adapting to your movements throughout the night, this foam provides additional support and cushioning so you can get the most rejuvenating sleep possible.

A cleaner sleeping environment

A breathable elastic cover enhances airflow throughout the mattress, amplifying the Diamond Degree® technology's cooling properties. This cover is also removable, so you can easily keep this mattress topper perfectly clean, which, coupled with hypoallergenic properties, ensures a fresh, hygienic sleeping environment.

Please note: This mattress topper was previously named the Emma Premium Mattress Topper.
