Seats and backrests
A sauna bench is in direct contact with the skin at 80-100 °C: the timber must be resin-free, dimensionally stable and pleasant to the touch. Our selection in alder, thermally modified pine, thermally modified oak and thermo abachi meets every one of these requirements.

Skin-contact species compared
Alder — a soft timber, gentle against the skin, moderate thermal conductivity. The traditional species.
Thermally modified pine — the resin is driven off by the treatment, even brown tone, more stable. The modern alternative.
Thermally modified oak — dense, hard-wearing timber, top-of-the-range finish.
Thermo abachi — light, pale African timber, very low thermal conductivity (ideal for a bench).

Alder remains the traditional Finnish timber: soft and resin-free. Thermally modified Scandinavian pine is a more stable, modern alternative. Thermo abachi is the least thermally conductive — ideal so it never burns on contact.
Roughly 1 m below the ceiling, where the heat gathers (steam rises). The lower bench (footrest level) sits 30-40 cm below the main one.
Pine and spruce contain resins that seep out at 80-100 °C — staining, a sticky feel and a risk of burns on contact. Thermal treatment drives these resins off, which makes both species suitable.
15 to 25 years with minimal upkeep. Thermally modified oak is very dense — it stands up well to wear and keeps a handsome brown tone over time.
