Durability is multifaceted, involving both surface hardness and dimensional stability. Exotic woods often lead in raw Janka hardness, which measures resistance to denting.

Because oak is widely available and well-understood by installers, it frequently offers more predictable long-term results than certain exotic species that may react unpredictably to changes in humidity.
