If the goal is something that reads weird for most Europeans, then try picking names from Finnish, Estonian, Hungarian, or Welsh.
Funnily enough, there are quite a few IKEA products with Finnish names. (Most are place names from northern Sweden, where there's a significant Finnish minority.)
Now I want a HÉTFŐ desk, and a SZÉKESFEHÉRVÁR... something.
Basque would be truly weird since it is one of a few known language isolates
Imagine an alternative reality where a KALLAX is a ԿԱԼԼԱՔՍ and the stores have pushy salesmen with impressive amounts of visible chest hair.
You really wanna get weird, there's those continents of Asia, Africa, and South America, full of different sounds to use for names. Ikea is Swedish, so they get to propagate Swedish culture to the rest of the world.
My missus is Hungarian, I'm sure it's a lovely language but it just sounds like Klingon to me.
Which makes it hilarious when she's annoyed at the boy.
