I have a couch that's moved twice and it is as good as it was when I bought it.
IKEA makes many products that are metal(I have a couple carts like that) and even some of their particle board furniture(two large dressers I have) do fine if you move them carefully.
My moves were from SoCal to the Bay Area and back, so not cross country, but not local either.
My Friheten sleeping couch has been through three complete disassembly processes, has been my daily couch for about three years (then relegated to a guest bedroom) and has been used as bed a few dozen times, but it’s still pristine. Plenty of other IKEA furniture has been through three movings too and it’s still good.
How you treat your stuff and how carefully you (dis)assemble it matters a lot.
