I have seen it before, but that was a long time ago. The name ... ???
Probably a predecessor.
Was it a series, meaning with different options, or a single shelf?
If it was a series, then I’m sure it’s Ivar. If it was a single shelf, I think the name was different. I just don’t know. 20 years ago I hadn’t even thought about my first own apartment, let alone IKEA.
But respect, 20 years old and still in such good condition, not even all cars manage that. It’s basically a classic.
