Wa offers visual simplicity without technical compromise. The underside of every worksurface is fitted with a perimeter slot. A simple clip allows you to connect anywhere along the entire table edge.
Storage, worksurfaces and accessories can dock at any point in the slot.

Work surfaces: HPL faced board; extruded aluminium track. Structure: Rectangular section steel tube & bar; stamped steel plate; folded steel sheet. Light panels: Solid core laminate; die cast aluminium.


"Wa has two colour palettes, neutral and accent. For the larger surfaces a neutral palette of tone on tone is employed, ranging from white, to off white, through grey to carbon. The various tones sit comfortably side by side in any combination." Piero Lissoni

"In addition to the neutral tones, a second palette of accent colours is applied to the storage door panels and accessories. The carefully chosen shades of red, yellow and blue are in stark contrast to the neutral palette. Later in the project it was felt that a completely neutral palette would also be desirable for such elements, so the tonal range was also extended to include the accessories." Marc Krusin

5 Wa core colours; White, Off-white, Light grey, Grey-beige & Carbon. Carbon zinc detail.


Almost any configuration is possible. There are no modular restrictions. Legs can be fitted to the corners of desks or shared between two worksurfaces. A range of 'soft parts' offer an interface between the body and workplace. They can connect anywhere on the desk perimeter.

Product Story image

“The challenge with WA was to accommodate the rigorous performance criteria, but retain a visual silence. The requirements of office furniture are probably the most demanding that we have worked with. We have created a very practical, a highly technically capable system that is still clearly in the Lissoni spirit. That gives me great satisfaction.“ Marc Krusin.

Designer image

Piero Lissoni began his career as a furniture designer after receiving his degree in architecture from the Politecnico di Milano. In 1986 he founded his own studio, which specialised in architecture, furniture, interiors, and graphic design, and produced a diverse architecture portfolio that included designs for showrooms, yachts, private residences and hotels.

In 2004 Knoll introduced Pierro Lissoni’s Divina Lounge Collection, originally designed for his long time client, Living Divina. Two years later, he and his studio’s design manager, Marc Krusin, co-designed the wa office system for Knoll International. With no predetermined connection points, the brilliantly simple design featured a patented 360 degree clip mechanism allowing any component to be attached to any workstation, on any side.

Marc Krusin was born in London in 1973. He graduated in the UK and after placements with Fred Scott and George Sowden, he began his career in Milan collaborating as a designer with various studios. These include Piero Lissoni’s office, where he is presently design manager and runs projects for clients of international reputation such as Alessi, Kartell, Flos, Thonet, Wella, Fritz Hansen and Knoll.

In 1998 he co-founded the Milan based group Codice 31 with five other designers from diverse backgrounds. The group’s first appearance was at the 1998 Milan furniture fair’s “Salone Satellite” exhibition for young designers and in successive years it enjoyed continual expansion and gained an increasing importance in the design world, collaborating with some of the sector’s most prestigious companies. Since 2004 he has collaborated with Omnidecor and in 2006 a series of Marc’s decorations for float glass were commercialised marking the beginning of a close working relationship which led to an entire new product image and presentation concept designed by Marc for the company. Marc has continued to design furniture, products, exhibitions and spaces for well-known companies in the design industry.
