“Sitting 4.0”

The armchair Rex revolutionizes the act of sitting. Like the de Sede model DS-343, the armchair Rex is based on a patented seat study developed over the last two decades by seat expert and physical therapist Bart Van der Heyden. Rex is an armchair that moves with the movements of the person seated. Changes in posture are not just permitted but even encouraged.

The armchair presents itself in a novel architecture. The seat shell does not stop at the backrest as usual but extends to pelvis height instead. This is not only a stylish design element but the elementary basis for this sitting revolution. With the extended seat shell, the person seated assumes a different posture when leaning back: if you lean backwards, only the upper part of the backrest moves backwards. Following the movements of the body, this provides gentle support to the spine and the chest opens automatically. The person seated immediately feels a more open posture, which is accompanied by a freedom of sitting.

Sit yourself to health!

1. The armchair seat shell is extended to pelvic height. This ensures an ergonomic sitting posture.
2. If you lean backwards, only the upper part of the backrest moves backwards. This provides gentle support to the spine and the chest opens automatically. This creates a liberating seating comfort.
3. In addition to the backrest, the seat shell automatically tilts backwards to achieve an even better lying and relaxing position. This innovative movement mechanism is patented.

NATURALE

Type

Natural Nappa leather

Thickness

1.5 to 1.7 mm

Characteristics

Unquestionably the most authentic form, a leather possessing all the positive properties of the natural material – exceptionally soft and supple and with an almost silky feel. Its original character is emphasised by subtle differences in colour intensity. Naturale undergoes visible ageing and over the years and takes on a distinct patina – a surface with a story and personality.

One-of-a-kind thanks to the authentic structure and silky sheen of the untreated skin – a leather that cannot be more original or of better quality. Particularly fine and intensive in its unparalleled feel. The ageing process creates an especially authentic and exquisite patina.
