Designed for a lifetime of flexibility, the Flex chair creates a perfect spot to sit solo or can be combined with other Flex modular seating when it's time to expand. Built with Blue Steel Spring technology and sustainable stain-resistant performance fabric, the Flex chair provides deep-seated, blissful comfort and long-lasting durability. And assembly is a breeze with a patented J-bracket "no-tool" method that takes minutes, rather than hours.
