Sapper | Ergonomic Office Chair: Mechanism as Form

An office chair where all adjustment mechanisms are exposed and become part of the design: behind the backrest are visible tilt mechanisms and tension adjustment wheels; armrest height and angle are adjusted by exposed sliders and knobs; seat depth is adjusted by a side lever. Every operating point is within natural reach, no need to look down. The seat and backrest are elastic mesh stretched over a frame, showing the weave and tension direction. Metal parts are black powder-coated. The entire chair has no decorative casing. Rear-oblique view.
Avoid: mechanisms enclosed in plastic casings, adjustment knobs hidden under the seat, thick soft cushions, leather upholstery.

一張辦公椅,所有的調整機構都外露並成為造型的一部分:椅背後方是可見的傾仰機構與張力調整輪、扶手的高度與角度靠外露的滑軌與旋鈕、座面深度以一個側面的拉桿調整。每一個操作點都在手自然摸得到的位置,不需要低頭找。座背是繃在框上的彈性網布,可以看見織紋與張力方向。金屬件是黑色的粉體烤漆。整張椅子沒有任何裝飾性的外殼包覆。斜後方視角。避免:機構包在塑料外殼裡、調整鈕藏在座面底下、使用厚的軟墊、加入皮革包覆。
