B3 BACKREST HEIGHT ADJUSTMENT
Sitting on the chair, holding and
pushing up the Backrest height
adjust mechanism, one could
adjust the backrest up or down,
the backrest would be returned
back to the lowest when
pushed to the top. There is
six-position and 6.5cm
adjustable.
It is the best suitable position
that the 3-4 vertebra is
supported on the lumbar-rest
position, and with the especial
contour design, one’s vertebra
could be in the most health
position.
