This is the highest quality grade, richest, and most luxurious memory foam (visco elastic) available on the market today, the state of the art after more than ten years of development. Completely different from the many cheaper or Chinese memory foam grades. This amazing material moulds and flows to the shape of your body to provide even all over support with no pressure points. The result is the most conforming and comfortable sleep possible. Made from natural Soy, and good for you and the environment. Free from flame retardant or other toxic chemicals. This chemical free foam is often certified “Toy Safe” meaning it is safe for children to play with and even eat large quantities without ill effects. Completely non-toxic and hypoallergenic. Good for the top of the bed as a pad, or as the top layer of the mattress if you build your own bed. Made in USA
