Cover
Anti-microbial knitted cover - The cover is not removable or washable. The grey base fabric can be cleaned with a soft, damp and clean cloth using small circular motions. Using a mattress protector could help extend the life of your mattress.
The cover gives you a delicate, soft feel to lie on. It is also liquid repellent to avoid any accidents. The sides are made of mesh, which allows the mattress to be more breathable.

Comfort
The Simba® 1500 Mattress is 10" deep. Our Simbatex foam uses advanced graphite cooling technology to draw heat away from your body, keeping you cool and comfortable. Simbatex memory foam infused with graphite for cooling
The ventilated viscoelastic hybrid foam is anti-microbial and prevents any moisture from accumulating. The top layer allows air to circulate, keeping you cool while adapting to your body. It identifies the pressure points, reduces the temperature and the firmness of these points in seconds only.
Support
The Simba® 1500 is built for those who are looking for a firmer comfort. Experience up to 1500 patented conical springs for supportive comfort and airflow.
An element that makes this mattress truly unique is the proprietary support frame. This keeps the mattress from flattening out when you sit along any of the edges and helps to reinforce the structure. The support layer serves as a transition between the top layer and the base. It is designed for your comfort and provides full body support to ensure a better sleep. The first layer, or base, of the ultimate mattress is built with high-density foam and acts as a boxspring, while providing unparalleled reinforcement. It adds durability, strength and comfort without feeling too firm.
