Never gave it that much thought but what you are saying is probably the reason that I never coveted NEW things. 55 years ago, my Aunt moved into a smaller house and I purchased her 15 year old solid maple Bassett bedroom set for $50.00 That set is 70 years old today and I wouldn’t sell it for any price if I couldn’t replace it for one like it. It is all mortice and tenon, dovetail workmanship, not a nail or screw in it, never had a drawer stick. That is more than I can say for any of the new bedroom sets I have purchased for my children over the years. My dining room table is over 100 years old, in perfect condition, was salvaged from my Grandmother’s shed many years ago. The top is polished to a high shine and you can see the original dowels used in the building of it.
For most things, new is not necessarily better.
Sounds like you have lovely furniture. And that it will last another 100 years!
There’s a furniture store that offers ridiculous things in their ads, like no payments for 5 years, etc. We went there once and their furniture was very cheapily built - all veneers and not even good ones at that. It probably won’t even last until the first payment is due! And the store was packed with people buying like crazy during the greedy years (up until about 2 years ago when house prices came back to reasonable).
