How does the possessive adjective su function in this sentence, and to whom does it refer?

Why is the preposition para used in the phrase para su escritorio, and what does it imply?

How is the adjective phrase muy cómoda constructed, and how does adjective placement differ from English?

In Spanish, adjectives typically follow the noun they modify. Here, cómoda (comfortable) comes after silla (chair), and the adverb muy (very) is placed before cómoda to intensify it. This order contrasts with English, where adjectives and their intensifiers usually precede the noun (i.e., "a very comfortable chair").
