3. concept
Norma is caracterized by a very clean and
elegant design
The mechanism of the chair is connected to
the seat trough a very elegant system of
leverage
Just like every item in the Alias product
range,
norma, styled by Michele De Lucchi and
Philippe Nigro, is the expression of ongoing
research into materials and manufacturing
systems geared to the attainment of
aesthetic
and functional excellence. Characterised by
stylish, sinuous design, this office chair is the
fruit of an extensive testing program, leading
to a tale of perfection and homogeneity,
where aesthetics, sturdiness and structural
quality play the star role.

5. Ergonomy
the mash
When you stand, the mesh regains its original form. The process for attaching the Pellicle
to the chair frame ensures that the material retains its responsiveness,
shape and strength over time.
The mesh conforms naturally to your contours. It minimises uncomfortable pressure
points by properly distributing your weight over the seat and back, away from your spine
and the backs of your thighs. Air flows through the Pellicle to prevent heat build-up and
allow moisture to dissipate.

6. Ergonomy
the geometry
The Norma moves in sync with your body, thanks to the syncronized mechanism. When
you recline or move to a forward posture, the chair simply move naturally and the tilt
responds.
You stay balanced and in control. Combined with the chair’s adjustability, the tilt gives
healthful, comfortable support for a full range of postures, for all kinds of work –
keyboarding, reading, meeting, phoning or contemplating.
The tilt lets the body pivot at the ankles, knees and hips so you change posture with ease.
As you recline through a generous 30-degree range, your upper body weight transfers
from your lower back to the high and wide backrest.

7. Ergonomy
back support
The back support has been developed for the lower back, below the belt.
Back support provides that critical support to sustain a healthful
posture and enjoy custom-fitted, lower-back comfort – no matter
how long you’re seated.
When you sit upright at a computer, there’s a void between the base of the
backrest and your lower back. When that area is not supported, your hips
tend to rotate back and your spine loses its healthful S-shape. In other words,
you slouch. Back support addresses this root cause of poor posture by filling
in the void and supporting your lower spine. In addition you can adjust
back support to provide the most comfortable level of support.
