Walter Knoll Sheru chair swivel • 4-star base cross • without armrests

Walter Knoll Sheru chair • 4-star base cross

An elegant, comfortable chair that effortlessly balances working, living and wellbeing. Thanks to the new chAIR technology, the breathable shell chair offers high seating comfort and pleasant ventilation. Ideal for hours of conversation – with family, at friends' homes, in meetings or at conferences.

The Sheru range offers maximum variety and numerous applications: depending on the setting and style, the base frames can be individually configured – choose between solid wood or tubular frames, as well as four-star or five-star base crosses. There is also a choice between relaxed or tailored upholstery. All upholstery covers are removable. All models follow the same design language. Even when combining different frames and variants, the overall appearance remains harmonious and consistent.

The Walter Knoll development team, together with the design trio EOOS, completely rethought the technology of a shell chair. The innovation of the chAIR technology lies in the seat shell: it contains hidden openings in the seat and back. In the seating area, these openings feature bands arranged in a palm-leaf pattern, creating a pleasantly springy seating feel. At the same time, the openings ensure good ventilation. After a long life cycle, all materials can be easily separated from one another and recycled by material type.

The next generation, Sheru evo: Walter Knoll has further developed Sheru chAIR with sustainability in mind. Sheru evo is part of Walter Knoll's evo concept. The material and construction have been fundamentally revised. What's new: in the evo models, the upholstery is worked directly into the cover. Thanks to the intelligent construction, Walter Knoll can dispense with adhesives entirely. This creates long-term added value and represents a consistent further development of the existing concept.

"EOOS designed the shell from a refined cut, like the great masters of fashion. It happens as if by itself. Magical." – Markus Benz, CEO Walter Knoll

Note: leather hides are selected by specialists according to strict guidelines and high inspection standards. Leather naturally has both soft and firm areas of hide, which may be used alongside one another. It stretches through body heat and moisture during use, which to some extent results in waves and creases (so-called seating hollows). Favourite seats show this particularly clearly. This settling process is largely complete after a few weeks; any further stretching is minimal and unobtrusive. Depending on the tanning method, colouring and surface treatment, leather initially has a characteristic smell, which noticeably diminishes over a few weeks; airing the room can speed this up. Walter Knoll uses several leather hides for one upholstered set. No hide is identical to another. Insect bites, small injuries from fences, or marks from tussles leave small scars on the cattle hide that you may rediscover in the leather. Fattening folds are a sign of the animal's health and good nutrition. These material-typical characteristics do not affect the quality of the leather furniture. Differences in sheen, colour and texture within a single hide and between the cut pieces of a cover are also characteristic and typical of leather furniture.
