Good for you,
good for the planet.

Rest easy as every Simba mattress
is made from Simba-Pure.





Foam in other brand’s mattresses include TCPP and other chemicals - including phosphate, parabens, biocides and persistent organic pollutants. These chemicals are safe to you but are old ingredients to meet fire safety regulations.

All those chemicals aren’t good for the planet... After years of research and development, Simba produced Simba-Pure, a purer foam that is free from those chemicals. Of course, it exceeds fire safety regulations.

Pure innovation that’s better for you, and better for the planet.

And that all adds up to longer, deeper, cooler Simba sleep.
