I'm currently using an ~80-year-old bedroom set. It's been moved ~7 times, and is still rock solid. It ain't new, nor trendy, nor did I ever get the thrill of shopping & buying exactly what I wanted - it's a hand-me-down from an aunt & uncle (who were born ~1895, if I recall). Back in the day, that's what families did with good furniture.
Physically, I'd guess that my bedroom set would be good for another 120 years or so. But since the younger generations, these days, are mostly set on buying all-new stuff for themselves, no matter the quality...
