guide/show someone to his seat

They asked me to show the lady to her seat. - Showing people to their seats is the common function of an usher. You can also use the verb "usher" but it is not as common.

Gene93Can we also use "take someone to his seat"?

Yes.

Yes, I am familiar with "usher". Do "take" and "show to" sound more natural than guide? I don't think I'd use guide, but that's probably just me.

Gene93I don't think I'd use guide

Use a guide in the wilderness, the jungle or on a rafting trip, not to get to a numbered seat in a theater.

Escort might work, but some might say it's a little too dramatic.

No, it suggests a situational relationship.
Prisoners are escorted by guards.
The president is escorted by his security detail.
The father escorts his daughter down the aisle.

A friend of mine used "guide people to their seats" in her CV. She's a native speaker and that made me question myself. I thought natives didn't make any mistakes.

It's not wrong.

Gene93 "Could you, please, help the lady get to her seat"?

Yes.

Thank you.
