I just learned a new nightmare that will also prevent me ever moving back to America.

In Victoria, a used mattress has to be clearly labeled as such by law at sale.

In many American states, mattress stores can simply reupholster a used mattress and sell it as brand new.

I may never sleep again.

@hacks4pancakes to be fair.... The requirement is all upholstery needs to be removed, leaving nothing but the inner springs. Then it gets all new fabrics.
@Stinkie @hacks4pancakes that seems a lot more reasonable. Also troublesome enough that it'd never be done for anything except some handmade bespoke mattresses (thinking the kind of thing you might get if you're a near 7 foot tall basketball player)
@fencepost @hacks4pancakes surprisingly there was a really successful factory in my area that remanufactured beds. I think they went under during COVID
