Why is abachi preferred over cedar for European saunas?

While Western Red Cedar is popular in North American saunas for its aroma and natural rot resistance, abachi has significantly lower thermal conductivity — meaning it stays cooler to the touch at the same air temperature. For direct-skin-contact surfaces (benches, backrests), abachi is the safer and more comfortable specification.
