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.

FAQs

Simba 1500

Can I clean my mattress?

Yes, you can clean your mattress using light fabric cleaning products or a soft, damp cloth. However, we do not recommend removing the cover.

Will I be able to get the mattress back in the box?

Once the mattress is out of the box, it cannot be put back inside. We also do not recommend attempting to fold or roll it as this may damage the spring layer inside.

Will my mattress have a smell when i first open it?

There might be a slightly unusual smell for the first few nights due to the fresh-out-of-the-box foam. However, this smell will fade away after a few days and will not return.
