Not very surprising to me. IKEA is always very thoughtful and clever in their design of even the most mundane things. I've never seen them botch anything ever.
Also, IIRC, they were a very early Linux adopter, I think in the '90s one of the largest users. It seems that Ikea has some smart techs on board and that - here comes the actual surprise - they listen to them.
The designs of their physical products are generally good, granted, it's the implementation that is lacking, often severely.
They do regularly recall toys that were found to be dangerous.
