Bauhaus tubular steel chair: form derived from function

A product photograph of an early modernist tubular steel chair: the structure is polished chrome-plated steel tubing, geometrically extremely simple—straight lines and bends of equal radius, with no decorative elements whatsoever. The seat and backrest are black leather or canvas straps stretched over the steel tube frame, with tension adjusted by exposed side buckles. The entire chair consists of only three materials: steel, leather/canvas, and screws, and the function of each component is evident. Proportions strictly follow combinations of rectangles and circles. Pure white background, direct side view, strong directional light making the highlights on the steel tubes a continuous bright line.
Avoid: Adding curved shapes or decorative moldings, using wooden components, hidden buckles, seat made of thick soft cushions.

一張早期現代主義的鋼管椅產品照:結構是拋光的鍍鉻鋼管,幾何極度單純——直線與等半徑的彎,沒有一處是裝飾。座面與椅背是繃在鋼管框上的黑色皮革或帆布帶,張力靠側面的皮帶扣調整,扣件外露。整張椅子只有鋼、皮、螺絲三種材料,而且看得出每一個構件的功能。比例嚴格依循矩形與圓的組合。純白背景,正側視角,強烈的方向光讓鋼管的高光成為一條連續的亮線。避免:加入曲面造型或裝飾線腳、使用木質構件、扣件藏起來、座面做成厚軟墊。
