In a sense. But their designs are fairly timeless, and while their cheapest product lines don't hold up to much abuse they still last 10+ years under normal use. A fraction of what good furniture will last, but long enough that usually your needs change faster than the furniture breaks.

Or until it gets scrapped because it went out of fashion. People usually don't renovate because their furnishings are falling apart but because they want something fresh.
I tend to agree. Styles change, needs change as people move and/or change lifestyles. I have some pretty old furniture but I mostly own it because I can find a space for it--not because I'd buy it today.
