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.
