Sedus mr. 24 User manual

Instructions for use
mr. 24

®Use the whole seat surface
The anatomically shaped seat should be fully occupied.
Only then is proper contact with the supporting backrest
assured.
mr. 24 is fitted with a sliding seat as standard. The seat
allows different sizes of people to use the chair.
®Adjust the height of the seat precisely
The correct seat height means that the elbow joint
adopts an angle of about 90°when the forearms are
resting horizontally on the desktop. The knee joint
will also adopt an angle of about 90°when the feet
are flat on the floor. If your desktop is too high, and
cannot be lowered to a correct position, you need a
footrest with adjustable height and tilt.
®Adjust the backrest
Adjust the height of the lumbar support so that the
curvature of the backrest supports the spine in the
region of the third and fourth lumbar vertebrae (where
the forward curvature is greatest). This stabilises the
natural S-shape of the spine in every sitting position.
mr. 24 has a multi-adjustable lumbar curve in order
to support the lumbar area.
®Dynamic sitting
Dynamic sitting means changing your sitting posture
frequently, or in other words shifting as often as
possible between the front and rear sitting posture.
You should therefore adjust the backrest dynamically.
mr. 24 is equipped with a “Similar” mechanism,
allowing you to adjust the backrest pressure as best
suits you. This ensures that the backrest and seat
automatically give your body support in every sitting/
lying position.

Correct use
This office swivel chair is designed
for a user weight of up to 200 kg
and may only be used for the pur-
pose intended while exercising due
care and attention. Using it inap-
propriately (e.g. as a stepladder,
sitting on the armrests or placing
extreme weight on one side) could
result in accidents.
Castors
Please remove the red or blue
transport protection before using
the product for the first time.
A variety of castors are available,
for the sake of your safety and for
use on different types of flooring in
accordance with safety regulations:
– Hard castors for soft flooring
(standard)
– Soft castors for hard floors are
optional
Changing castors: this might be
necessary, for instance, after
moving office, or after the instal-
lation of a new floor covering –
simply pull out the castors and
push new ones in.
Plastic parts
Soapy water is suitable for clean-
ing. Please do not use any
aggressive cleaning materials.

For light dirty marks, only clean the
cover material using fine washing
agents or using the cleaner sup-
plied by Sedus.
The seat and backrest can only be
replaced in the factory.
Leather
Leather is a natural product.
The natural markings of the
animal skin gives the material
its unmistakable texture.
Rub off light soiling with a soft
woollen cloth. Heavier soiling
should only be treated with
cleaners designed for aniline-
dyed leather.
Do not expose semi-aniline
leather to direct sunshine.
Servicing
Servicing work, such as exchanging
or working on the pneumatic
