Option: Flexsit
The front edge ➎ of the seat is flexible and yields
automatically to pressure exerted by the thighs. This
enables shorter persons to set the seat higher when
working at desks which are not height-adjustable, without
incurring pressure marks on the backs of the thighs. The
entire seat surface remains available to taller persons, as
they do not exert any pressure on the front edge of the seat.
Option: Height-adjustable armrests
Press the adjustment button ➏ which is fitted to both
armrests and adjust the height of the armrests so that the
forearms take up a relaxed position on the armrests and
the strain on the shoulder muscles is relieved. Desk and
armrests should be at the same height.
Option: Lumbar support
Swivel chair: An adjustable lumbar
support (3,5 cm in depth) ensures optimum
support of the lower back, tailored to the
size of the user.
Setting the cur vature of the lumbar suppor t:
Adjustment range: Depth adjustment of 3,5 cm by turning
the handwheel. Setting the backrest: Set to desired
position by means of height adjustment feature.
Turn the handwheel ➍ on the side of the backrest to adjust
the backrest curvature to your personal requirements.
When you lean back against the backrest, you should feel
an evenly distributed counterpressure in the lumbar region.
