The best mattresses in the world are made with organic, 100% natural latex rubber. No other material comes close in terms of comfort, breathability, resiliency, elasticity, motion isolation, durability, support, and even biodegradability. It makes a superior comfort and support layer. (We use it for both.) And the most desirable and scarce latex is GOLS organic certified latex — grown ethically, sustainably, and responsibly — without persistent pesticides and herbicides, on USDA's NOP organic-certified family cooperatives, and processed in organic certified facilities to stringent standards. Organic latex is safe for farmers and their families, better for you, and better for the planet.

It's also incredibly resilient. Latex can survive below freezing temperatures as well as extremely hot and dry temperatures. If latex gets cold, it may take a bit longer to regain its original shape — but in the long term it will be fine.
