Can we talk about these chairs?
Well, we're going to. Or at least I am.
1) Making something using steel plate doesn't make it "industrial style". In this case it just means you've used unsuitable materials in an inappropriate fashion.

Whoever *designed* these chairs isn't a designer. And throwing together disparate materials in the hope that the results will be "industrial" shows a complete disregard for the heritage, and lack of knowledge/understanding of industrial design.

These are a shit-show of a chair. Ugly, lacking any merit other than the fact that unless a tank plonks its arse down on one the legs are probably never going to break. They're ostentatiously awful. Unapologetically awful.

The reason there are 30 of these fucking things available, at what I suspect is less than the value of the steel, cutting, forming and bolts, is people didn't buy them because they're fucking ugly, heavy, and will fuck your floor up quicker than a herd of rampant wildebeest

Stop trying to be edgy and be *better*. Read a book or two. Do some research. *Look*. Ask questions. Buy lower gauge steel plate. Stop making ugly and impractical chairs. Make candles. Fuck off.

As an example of what is good industrial design there's this...
Still made from steel, but much thinner gauge to ensure they're not too heavy. In order to retain the strength required the steel is pressed, providing rigidity.

Components are easily produced on a production line and quick to assemble. The materials are selected for durability and strength, and to reduce the need for maintenance.

The steel feet aren't capped because they're made for an industrial setting where flooring is likely to be hard, concrete, tile, heavy wooden boards or stone. They're fit for purpose. Designed to be used for decades. They sold in huge quantities because they were designed well.

You couldn't buy one of these 1920s stools for a tenner today. They're a design classic. They were designed for purpose by a designer who understood the brief and the materials and processes required to produce the product. These will be around when those others are long in recyc
