In general, MOST foam play flooring / mats are made with a material called EVA (ethylene vinyl acetate) which is a foam rubber compound. For a while now it has been viewed as a healthier alternative to PVC and the process of making it excludes the use of chlorine which can produce carcinogenic compounds called dioxins.
But these mats are real rubber, and this is the material your local gym might use. If price is no object, this is what you want. It is 100% virgin, not recycled, rubber formed into 24 x 24 mats, 3/8 thick, with a slick pebbled surfaced that the industry calls hammered..
