Cylinders (aka Gas Lifts or Pneumatic Cylinders) are a paradox. While they are one
of the easiest - and most important - parts of your chair to adjust, they can also be one
of the hardest parts of your chair to understand. Thankfully there is only one main
area that you really need to consider when specifying for that perfect fit: Travel Range.
TRAVEL RANGE is expressed in approximate inches and is the total distance that the
telescoping portion of the assembly can travel. A 5 inch cylinder has 5 inches of travel
from full compression to full extension, a 7 inch cylinder has 7 inches of travel, and
When considering the Travel Range for your seating needs, it is important to bear in
mind that your working environment and style together determine what?s appropriate
for you. See the chart below for more details.
BIFMA UTFF (Ultimate Test For Fit) for the work chair states that users should be
able to sit with their feet comfortably on the floor or footrest without undue pressure
on the underside of the thighs. The thigh-to-torso angle should not be less than 90?.
