(a) seated position

IvanhrYou should remain in seated position.
You shoud remain in a seated position.
I'm sure they're both grammatical. But my question is "Are there other nouns that can be used the same way as "position"?

Neither one is correct. The article is used in this case.

You should remain in a seated position.

I'm not sure about the que

Thanks.

So if the version without the article is incorrect then what about these

He finished in third position.

When the adjective is used in post position.....

IvanhrHe finished in third position.
When the adjective is used in post position.....

These are fine. Position in this context refers to a general ranking or order.

A seated position is not a rank or order, but a configuration (e.g. contrast with kneeling or standing)

Yes, I figured it out myself. I'd say the original sentence (the one without the article) is fine for giving instructions because the articles are usually left out in instructions. I forgot that instructions have a grammar of their own.

Thanks

IvanhrI'd say the original sentence (the one without the article) is fine for giving instructions

It is not natural to me, even consdering its use as an instruction. An instruction would be:

Remain seated.

I'm not sure whether the authors are native speakers but it's all over the page

Most of the phrases with "seated position" occur on the page you referenced with an article or determiner. The ones where the determiner is missing do not sound natural to me. But this is a formal engineering paper, concerning mechanics and valves, not people. Engineering writing can often be at variance with normal conversational speech in its omission of determiners.

Again, thank you for your help
