How did Princess Jasmine end up with a beautiful room at the Sultan's Palace?

Every time I watch Aladdin I always wondered how lovely they designed Princess Jasmine's room in the Sultan's Palace? Because I LOVE learning about the Disney Princesses bedrooms to get inspiration for designing my own bedroom. I noticed that Princess Jasmine's bedroom has a lot of blue in it and I think it looks beautiful to match the furniture in it. Also I noticed that rather than a bed Princess Jasmine sleeps on a fancy couch and I thought it looks lovely if I could take a nap on a couch like Princess Jasmine's but they should've given her a bed to sleep in rather than a couch. Also where does Rajah sleep because I never saw a bed for Rajah in Princess Jasmine's room? I also like the blue and gold blankets that Princess Jasmine has to decorate her couch and her cute olive-green pillow because the blankets look so beautiful and I wish I had a pillow like Princess Jasmine's to put my plushie next to me when I sleep
Who came up with the inspiration for Princess Jasmine's bedroom in Aladdin?
