Every three weeks, there's an event with furniture you can only get again when the event returns in a few months when it comes again. There however very rarely are events with furniture that can be gotten in that timeframe and then never again.

There are room/meme competitions every 3 days

Limited event furniture/cosmetics

Pixelings (including rare prisma) and Craniac furniture (some event specific) is tracked on the profile There are new event masks for all 3 week interval events, many people grind to get them all (you can only get 4 or 6 masks from previous events of the same type during one event)

Getting high places in room/meme competitions awards trophy furniture

There is a lootbox in the Bux shop where you get random furniture from cycling events
