When people say "designed to be disposable" they don't mean reuse is not possible - just not likely, because a thing wears out quickly, or is a hassle to give someone else. Former means there's not much of a second-hand market, the latter means that even giving away for free is too much work compared to just dumping it.

I'm very much surprised about the amount of comments here on HN (today and in many previous discussions) that claim to reuse IKEA furniture; it's completely contrary to my experience. My opinion of IKEA furniture is that it's single-assembly - trying to break it apart irreparably destroys it.

I conclude there must be either high variance in IKEA's production quality, or we're comparing apples to oranges. Maybe some IKEA products have more reassembly potential than others. Someone mentioned an office chair elsewhere in the thread - yeah, that obviously can last years and be moved, because it's made of metal and hard plastics. But most IKEA furniture I experienced is made of dried toilet paper glued with formaldehyde^W^W^W^W^W^Wmedium-density fibreboard and assembles destructively.

Not thought about the re-assembly side of things - most of the second hand items I have collected didn't need dismantling - they came as one unit. (At the cost of the annoyance of moving it as a single unit!)

I am sure there are different experiences out there, could also be the circle of friends that do a lot of IKEA "freecycling" meaning I do see a higher quantity of re-used items being moved about.

I know that depending on the type of item as well there is a build quality issue - like Kallax shelving, it is a little more sturdier than the slightly cheaper version, and given I started with Kallax, I have stuck with it - Same with the Billy book cases too!

Although, the Diam Cake you can get from IKEA... that 100% is not going to waste, and 100% no one is getting a "second hand" one from me... there will be none left ;)

But returning back! It could be Apples to Oranges, there are so many products, and in my experience I have seen people stick to the same grouping of products as well, which could see re-use more possible than say another grouping (for any number of reasons).

Who knows, tomorrow the shelf behind me might just fall apart and I will be back eating my own words :)

I've moved twice with all of my furniture and it's still going strong. The only thing that worries me for my next move would be the board on the back of my bookshelf, since it's only held in with very tiny nails.

If I understand which board you're talking about (a thin hardboard on the back), I'm usually not worried about that one - I have a stockpile of nails available, and I could probably reinforce it with something I have on hand if the edges degrade too much. My problems are usually that driving screws and other fasteners sometimes damages the material, making the connection single-use only. It's fixable to some extent with adhesives, but once you start pouring glue down the shafts, the whole thing becomes that much harder to disassemble in the future.

Some regions are more humid, and the same particleboard that lasts decades dry will break down quickly.

I see a lot of classic examples of survivorship bias in this thread.
