Kirn Office Chair

Kirn Office Chair is an environmentally friendly desk chair designed with green thinking in mind to make decisions black and white when looking to buy a new task chair.

Despite being around for 125-years, the office task chair in all its various versions from some great companies still presents designers with challenges.

So how do you create a compelling product in a market saturated by great office chair options? That is a question the designers at Orangebox always have in their design approach when developing the new innovative Kirn chair. As a leading office furniture manufacturer, they bring generations of innovation and value, not only with one chair but with all their office seating.

So how did they achieve this you might ask with the Kirn mesh back task chair? Well, typically a new mechanism is at the centre of a new chair, as is the case with Kirn. The second route is with materials and manufacturing and innovation, again with the Kirn task chair, they have created their first all mesh chair. The third is the architecture and design personality of the chair. That is where research of nearly a decade ago becomes an intrinsic part of the creative process. To understand the landscape of contemporary task chairs, Orangebox produced a research document where they set out what they saw as a living distinct chair architecture. All task chairs will sit within a specific range of chair frames, both existing and new. When looking at someone, we recall their body shape, how they move and more importantly, their face. The car grill and headlights have defined the car brand's DNA for generations.

Of the four primary elements of the task chair, the mechanism, seat, arms, and backrest is the primary definer of the chair's personality. So at current, each task chair developed by Orangebox originates from this. Each task chair lands up having a distinct design personality and as with the other vital assets — the mechanism the function of the chair attributes the materials of the chair. The performance range, the price point etc.

''Kirn's mechanism allows the bulk to be removed from under the seat where it's normally positioned and repositioned into the sides of the seat, which creates a lighter profile.'' - Gerard Taylor, Kirn Designer.

The Do office chair, one of the most successful office chairs by Orangebox features a fluid back connection architecture and their previous mesh chair Eva used a wishbone architecture. For the Kirn Task Chair, the designers originated the ideas around the connection through the arm architecture, which was their starting point for design developments. Working within this narrative is an innovative and helpful way to realize originality within a portfolio of task chairs together with contributions of each of the other key design assets. At the same time, the innovative mechanism that's central to the design of carbon, became a live possibility for development, so the design evolution of Kirn started.

This needs fixing before go live
For additional comfort in the back area, Kirn offers an optional adjustable lumbar support. The air-cell lumbar accessory provides the user 80mm of height adjustment and 20mm of depth adjustment. The fixed volume air cell uses air displacement to maintain optimum support in the back area, as the users shifts around.
This also needs fixing before go live
Kirn’s arms move with its back, just as ours do. Their rearward location option keeps them out the way of the desktop, and in an excellent position for easy adjustment. By doing away with adjustable triggers and buttons, Kirn makes setting them up as simple as moving the arm pads to where you want them to be.
