Ahrend Portal
A range of leg models
Ahrend Portal tables: with flooting and interposed tops
(figs. 1 and 2). For all functions this makes no difference.
Ahrend Portal tables are available as fixed height models
or in three height-adjustable versions. You can see the dif
-
ference in the vertical part of the table legs (figs. 3 to 6).
Working out the correct table
height
Sit on a table in a relaxed man-
ner with the backs of your knees
against the edge of the table. Three
important dimensions can now be
measured.
Dimension A:
the distance from the bottom of
the heel of the shoe to the top of
the table.
Dimension B:
the distance from the top of the
table to the underside of the elbow,
sitting upright, with the arm along-
side the body and bent at an angle
of 90 degrees.
Dimension C:
the distance between the top of the
table and a ruler placed across the
thighs, plus 5 cm. If this is greater
than dimension B, you should use
dimension C instead of dimension B.
The right work surface height for
you is the sum of dimensions A and
B (or A and C) rounded off to the
nearest even number.

Fixed table height
A fixed height Ahrend 500 table (fig. 3) is ideal for the
great majority of users engaged in normal office work and
for meeting and conference tables.
A fixed height of 75 cm is correct for people who are
between about 1.70 and 1.85 m tall (5ft 6ins to 6ft 1ins).
Shorter and taller people are advised to use a table in one
of the height-adjustable versions.
Correct ergonomic table height
Consult the table height advice below before adjusting
the table.
Standing meeting
Ahrend Portal offers the possibility of standing meeting
at a table with fixed height of 110 cm (113 cm for the
flooting tops).
