Sleep Science Black Diamond 11" Split-King Memory Foam Mattress with Adjustable Base
The Sleep Science Black Diamond Memory Foam Mattress layers proprietary bamboo charcoal visco memory foam and supportive latex. The Sleep Science black diamond visco memory foam is the latest advancement in the Sleep Science memory foam line.
The adjustable base is made of reinforced steel and slips easily into an existing bed frame or can be used as a stand-alone bed. It features one of the quietest motors on the market and a sleek, stylish, streamlined design. The adjustable base also has a massage feature that is available on the head, feet or both. The wireless remote has a simple design with large raised buttons and is backlit for ease of use in the dark.
The adjustable base has 3 pre-programmed positions on the wireless remote control:
- Zero Gravity (ZG): The ZG position, allows you to press one button and the bed automatically elevates both the head and feet for a feeling of floating suspension and cradling comfort.
- Reading: The reading position automatically lifts the head in order to sit up into a reading position.
- Flat: This feature allows you to press one button to return the mattress to a completely flat position.
The top layer of this mattress consists of 5 lb density, black diamond visco memory foam. It is the perfect top layer to absorb moisture and dissipate odor. The second layer is made of Sleep Science 5lb density premium visco memory foam to provide an added layer of comfort. The latex layer provides exceptional support for the visco memory foam. The mattress features the Sleep Science patented Wedge, edge to edge support system. The Wedge is an angled piece of firm polyurethane foam that runs along the outside edge of the mattress. It provides a stable sitting edge, 20% more sleeping surface than the competition and extends the life of the mattress by preventing the foam from spreading after prolonged use. The base features the Sleep Science air channel base which is made of high resilient polyurethane foam, that is scored horizontally and vertically in 1 inch grooves to promote air circulation in the center of the mattress, creating a temperature neutral environment.
