open up modern classic

Swivel chair & cantilever visitor chair

Admittedly, professional success can be extremely fulfilling. But is work really all there is? Surely someone who works hard and carries a lot of responsibility also deserves a reward. A day beside the sea, a ride out in a classic car with friends, exclusive accessories – the delightful things in life not only promise balance and pleasure, but are also an expression of one’s personality.

So why should this not extend to the office, whether at work or at home? The high-quality furniture in the Sedus modern classics edition delights with a quality of workmanship that meets the very highest standards. An independent design language, elegant materials and generous comfort will turn any working area into a place of character.

Impressions

Craftsmanship that gets the heart beating faster

How can a superb design be improved on even more? The answer: with real craftsmanship. Sedus open up modern classic shows this in a way that can be experienced with all the senses. One example is the soft, full-grain aniline leather with its very special feel. The natural characteristics of the leather are retained and have an especially high-quality look. At the same time, inviting upholstery offers additional comfort that the stepped look of the cushion effectively underlines. Each open up modern classic is made by hand and bears the signature of the Sedus employee who made it. Made in Germany.

Cosy

Generously dimensioned armrest pads match the comfortable upholstery of the backrest and seat in every respect.

Perfect

Genuinely hand-made – confirmed by the signature of the Sedus member of staff who made it.

Aesthetic

The high-quality castors with tread protect the floor covering and attract admiring glances.
