Sideways is Smith & Fong's slant on a cleaner, greener floor. All the wood for the Sideways line is domestically sourced, FSC-certified and the flooring is made right here in America. Their manufacturing processes use 100% formaldehyde-free adhesives to ensure indoor air quality. The deep, rich tone and luster of Sideways engineered hardwood flooring comes from a proprietary thermal treatment process that requires no added stains, dyes or toxic chemicals to achieve its signature look. And with an easy-install, click-lock system that ensures a faster, lower cost installation, you could almost think of doing it yourself.
