In rare cases, when you first unpack your Funzy from its roll-packed form, you may notice a "chemical" odor. A slight odor is typical for PUR foam, but is not harmful to health and is absolutely harmless. If you leave the Funzy well ventilated for a few hours or days after unpacking, the inherent odor should quickly dissipate. Our entire production in Germany is TÜV and GS certified and free of harmful substances according to OEKO-TEX Standard 100.
