So the idea of "buy it for life" is to buy items that are durable and last for a long time, things you could buy once and have your whole life, which can save money and be good for the environment
What are some of the top items you recommend for this?
Well, not small objects per se, but wood furniture, real wood, not laminate shit. I have some real wood furniture for more than 25 years, table, chairs, sideboard/dresser, etc. Some are even antique bought for $25 25 years ago.
Bonus points if you budget a little extra and make friends with a local upholster. They can work magic in turning that solid, but ugly, chair from something your grandma would have to something you might find in a design magazine.
