How safe are these for use in a kids playroom? Any bad chemical smell? Formamide free? Our gym space will also double as a kids playroom and want to make sure it's safe for the little ones.

Our 7/8" Tatami Tiles are very safe and are Formamide and Phthalate free. They do not have a chemical smell, but there may be a slight odor similar to a new toy. You can mitigate this with a little soap and water. To get the testing results for our Tatami Tiles, please feel free to reach out to one of our Flooring Heroes via email, chat or phone.
