Amazon.com Review: From foundation to fabric, every layer of Simmons Natural Care mattresses is made from high-quality ecological materials that not only provide a good night's sleep, but give the earth a reason to rest easy too. Each mattress features a natural latex foam core derived from the milk sap of rubber trees sourced from sustainable, renewable, and protected plantations. This latex, enhanced with soy, is soft yet supportive as well as hypoallergenic and dust-, mite-, mold-, and mildew-resistant. Highly resilient and durable, the foam will also maintain its shape and solid performance for many years of sweet dreaming (and eventually, it's biodegradable).

The top panel is a luxurious, breathable knit fabric produced from cultivated white pine wood fiber and, like the foam core, is Oeko-Tex Standard 100 certified for being free of harmful substances and produced under environment-friendly conditions. The foundation wood is typically sourced from companies who participate in the Sustainable Forestry Initiative. Ready to lie down? This Patterson Plush model combines 3/4-inch firm foam and 1-inch comfort block foam over the standard inner core. It is available in Twin, Twin Extra Long, Full, Queen, King, and Cal King sizes. All Natural Care mattresses are backed with a 20-year limited warranty. --Kara Karll
