The anwer guidot gave, already stated that “there is no single word order in German”, and that's why it is so important that the flexion endings clarify the relation.
The emphasis part seems not quite correct to me. As it is usually hard to understand emphasis from telling “the rules” alone, here two realistic Q&A examples to help you understand:
Q: Wohin bringen wir den Stuhl? A: Wir bringen den Stuhl zur Schwester.
Q: Was bringen wir der Schwester? A: Wir bringen der Schwester den Stuhl.
From my perspective, the emphasis in both answers lies on the end. Typically beginnings and endings of things we observe over time get the most attention. In the Q&A examples shown above, the emphasis is placed on that part of the sentence that answers the question.
There is also a difference in meaning between der (Wem?) and zu der (=zur, Wohin?), that I try to explain with two alternative answer sentences with the emphasis in the beginning of the answer:
Q: Wem bringen wir den Stuhl? A: Der Schwester bringen wir den Stuhl.
Q: Was bringen wir zur Schwester? A: Den Stuhl bringen wir zur Schwester.
In all four answer sentences the emphasis is given to that part that isn't already known from the question.
