This high quality firm foam is made from natural Soy, and good for you and the environment. For those who prefer a firmer feel. 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. Could be used for the top of the bed as a pad for those who prefer a firmer feel, or as the top, middle, or bottom layer of the mattress if you build your own bed. (Typically it is best if you build your own mattress to use a soft layer like memory foam or latex on top, a medium firmness layer in the middle, and a firm layer for the bottom. Or, you can be creative and build your bed with any combination of foams you choose.) Made in USA.
