Frameless Flex Back
With its high-performance elastomer Flex Back Net and distinctive figure 8 structure, this chair supports many postures and allows for multidimensional movement. The curvature of the figure 8 structure combined with the Net’s unique properties enables side-to-side flex and ensures optimal localized support for shoulders and lumbar region.
