'Veneer' is the term usually used. At that price, likely not solid, although butcher-block is not terribly expensive: a 240cm one is USD200 [1]. If the IKEA legs are just solid metal, it's entirely possible that it doesn't wobble provided they're affixed well.
Interesting product, maybe there's value in 3 different size slats to alleviate the seams problem while still providing flexibility?
