If you’re careful about which things you buy there it can last as long as any other furniture.

I’m sitting on a 12 year old couch and have a bed frame from 20 years ago upstairs that has survived 2 moves.

The key is no fiber/particle board, no fake leather and using wood glue on the pegs when building.

We have some “fancy” couches from West Elm that are already falling apart 4 years in. So much regret.
