User instructions

Do not leave the chair with the seat xed at an angle – this will
spare the mechanism’s spring when the chair is not in use.
Please do not sit on the chair with hard or sharp objects
(tools, mobile phone cases etc.).
A big ‘thank you’
... for deciding to buy a Svenstol
Svenstol 24h chairs have been specially developed for continuous
use around the clock. This means that all their parts are designed
to withstand high loads over long periods. Even so, you can make
a signicant contribution to years of satisfactory, trouble-free
service provided you use you chair correctly.
Incorrect use over time can cause damage for which unfortunately
we may not be able to oer any guarantee.
Please also read the special instructions on the use of our comfort
armrests on page 7 and the general instructions for use on the last
two pages.

activePlus mechanism
Active sitting – focussed work
In critical control room situations it is essential that the correct
decision is made quickly. Our activePlus mechanism helps you
meet this challenge with focus.
For active sitting, position the backrest at an angle of 90 to 95
degrees to the surface of the seat,  release the negative seat
tilt +and select the backrest resistance so that you are
pushed gently forwards when pressure is taken o the backrest.
Pressure and counter pressure maintain movement with no eort
on your part, the blood ow throughout your musculature impro-
ves, and muscular tension and poor posture are avoided.

The PU foam cladding on the comfort armrests oers a com-
bination of a wonderfully soft feel and a long life. With normal
use your armrests will last for many years – even if used 24
hours a day. However please avoid extreme, non-standard
loads as well as stresses such as wedging the chair under a
desk, ‘kneading’ the PU foam or using the armrest ends to
help you stand up when the chair is in the ‘relax position’.

User information
Use
This swivel chair should only be used with
general due diligence.
An accident could occur if used in a man-
ner other than that intended (e.g., sitting on
the armrests and standing aids).
Covers
Covers should only be cleaned with warm
water or neutral soapy water (shampoo)
when dirty.
Do not allow marks to remain for a long
period. Do not rub hard – if possible,
remove dirt with gentle dabbing.
Castors
Fitted as standard with castors for textile-
based ooring (carpets). Soft castors
should be used for safety reasons on
hard oors. If the ooring is changed, the
castors should be changed accordingly.
Seating surface
The seating surface is replaceable.
Tilt mechanism
In individual cases the tilt mechanism may
need to be readjusted after a certain period
of time. This can be done quite straightfor-
wardly: place a size 16 open-end spanner
on the nut (left side of the mechanism) and
turn it approx. ¼ of a turn clockwise. This
is usually sucient to restore the familiar
sitting comfort.
You can also request a FREE assembly
spanner of the correct size from
[email protected].
