FLEX C-shape chair

Model 7854

The ergonomically shaped FLEX seat shell made of robust and recyclable polypropylene is equipped with the easy-to-clean A2S surface structure. The special shape allows different sitting positions and ensures comfort in all directions.

The slightly springy, robust C-shaped frame supports the toning of the back muscles, promotes blood circulation to the brain and thus ensures greater concentration.

  • Fully upholstered FLEX (size 5-7)
  • Book tray (size 5-7)

  • Optionally available with book tray under the seat shell from size 5 and larger
