How long will the solid wood furniture Made in America, I'm investing in, how long will it last?

It'll last 10, 20, 30, 40, sometimes 50, sometimes 100 years, carried forward properly.

Solid wood furniture will last a lifetime, quite often going to be passed down from one generation to the next. That's why antiques are all solid wood. They're not veneer over particle board furniture.

This is the genuine article, the real thing.
