請協助翻譯為英文(將會議室桌椅恢復原狀),因為用google翻譯出來的結果怪怪的.謝謝?

"restore" has already the meaning of "returning something or someone to an earlier good condition or position".

Simply saying:
Restore the tables and chairs in the conference room.

Restore the Conference Room tables, chairs to their right places, clean and tidy.

Restore the meeting(conference) room tables and chairs to it's original look.
