Walter Knoll Sheru chair swivel • 4-star base cross • with armrests

Walter Knoll Sheru chair • base cross

An elegant, comfortable chair that effortlessly balances working, living and wellbeing. Thanks to the new chAIR technology, the breathable shell chair offers a high level of seating comfort and pleasant ventilation. Ideal for long conversations – with family, when hosting friends, or in meetings and conferences.

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

Together with the EOOS design trio, Walter Knoll's development team completely rethought the technology behind 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 seat area, straps are arranged in a palm-leaf pattern within these openings, 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 and recycled by 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. Materials and construction have been fundamentally revised. What's new: in the evo models, the upholstery is worked directly into the cover. Thanks to this intelligent construction, Walter Knoll is able to dispense with adhesives entirely. This creates lasting added value and represents a consistent evolution of the existing concept.

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

Note: leather hides are selected by specialists according to strict guidelines and high inspection standards. Due to its natural origin, leather has both soft and firm areas of hide, which may be used side by side. It stretches through body heat and moisture during use, which can result in a certain degree of rippling and creasing (so-called seating hollows). Favourite seating spots show this particularly clearly. This settling process is largely complete after a few weeks; further stretching is minimal and unobtrusive. Depending on the tanning method, dyeing and surface treatment, leather initially has a characteristic smell, which noticeably fades over the course of a few weeks; this can be accelerated by airing the item. Walter Knoll uses several hides for a single upholstered suite. No hide is identical to another. Insect bites, small injuries from fences, or marks from fighting leave small scars on the cowhide, which may reappear in the leather. Feeding 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.
