[Grammar] Those are some nice chairs.

[khanhhung2512]

These are the lines from "Grammar in Use Intermediate, 3e (North American English) - Cambridge University Press 2009":

We use a/an ... to say what kind of thing or person something/somebody is:
- That's a nice table.
In the plural, we use the noun alone (not some ...):
- Those are nice chairs. (not some nice chairs)

However, the sentence "Those are some nice chairs." sounds pretty normal to me.
What do you think about it?
Thanks a lot.

I am not a teacher.

I think the point that 'Grammar in Use' is making is that the plural of a/an in these cases is not 'some' but zero article.

'Those are some nice chairs' with the stress on 'some' means that they are particularly nice chairs.
