All genesis Habbo X rooms have a "room design" trait. This relates to the items inside the room and how they are arranged – basically what the room looks like. If you edit your room and move the items inside it around you'll also be able to reset the room to its original design.
In the future, the rarity of your room (common, uncommon, rare, epic, legendary) and the size of your room (regular, studio, junior, executive, or presidential) will directly affect the types of items your room produces with its Furni Factory. The rarer the room design trait, the rarer the items you’ll get from it on a monthly basis.
You can find more information about Furni Factories and which items your room gets based on its room design trait here.
