The Kepler office chair from Sitlife is an inexpensive office chair with a mesh back. With this affordable office chair you can easily adjust the spring force, backrest, seat depth (extendable to 6 cm), seat height and armrests (in height). The Kepler has a synchronous mechanism: a resilient technique in which the (set) support point for the pelvis is maintained in every position. You can set this based on your weight. The wheels of the Kepler office chair are suitable for smooth floors.
