Recommended for those who prefer softer ergonomic support. Our proprietary Responsive poly foam forms the foundation of this mattress and ensures that no part of your body sinks into the mattress more than it should through the night. This layer responds accurately to pressure; the more pressure your body exerts on the mattress, the more it reacts to support you. The top layer of temperature-sensitve memory foam responds to not just your weight but also you your body temperature and moulds itself to take the shape of your body; this means that the foam under the heavier parts of your body - hips and shoulders - compresses more than the foam under the lighter parts of your body - head, neck, legs - ensuring that you feel cradled through the night. It creates a feeling of weightlessness, almost like floating on water. This mattress also comes with a soft, high quality cover made from a combination of cashmere and 3 D spacer fabrics. The cashmere fabric pulls heat away from your body and towards the 3D spacer periphery, which then disperses the heat away from the mattress ensuring that you sleep cool even if you sleep without the AC on. The cover is treated with aloe vera gel to keep your skin hydrated and looking youthful.
