I was amused by this list of home decor items that don't belong in your house if you've over 30 - https://www.domain.com.au/living/home-decor-items-to-ditch-if-youre-over-30-20180118-h03b6j/
I certainly agree with bean bags!
What would you include on the list?
I nominate the humble futon.
Trophies from when you were a kid, inflatable furniture, movie posters, and that Billy Bass singing fish you thought was hilarious.
