OTSO Puro Backrests

Designed for comfort, style, and functionality. Sauna backrests play an essential role in creating a comfortable and well-designed sauna. They enhance seating comfort, elevate the visual appeal of the sauna, and protect the sauna wall from dirt and wear. An LED strip can be installed behind the backrests, allowing light to shine beautifully through the gaps between the boards, creating a warm, ambient glow.

OTSO Puro backrest elements feature softly rounded top and bottom edges, forming a smooth and even surface. The absence of sharp corners creates a noticeably softer feel and significantly improves comfort during longer sauna sessions. Installed using separate backrest supports OTSO Puro backrest elements are easy to remove for cleaning, making sauna maintenance effortless.
In addition to its primary use, the OTSO Puro backrest element can also be used as a cover panel between the upper and lower benches, ensuring a cohesive and refined sauna interior.
Structure also allows the elements to be easily shortened or modified as required.

The intelligent PURO bench structure is based on a wooden dowel construction. Each board is fitted with 8 mm wooden dowels at each end, allowing the bench elements to be packed tightly for efficient transport and enabling quick and easy assembly.


Each dowel joint is engineered to carry a load of up to 150 kg, ensuring exceptional strength and long-term durability. This structure also allows the elements to be easily shortened or modified as required.

Bench elements sit freely on the bench
frames for improved ventilation and hygiene. This design prevents water from being trapped between the bench frames and bench boards, reducing the risk of rot or mold. As a result, the benches dry efficiently, helping to prevent unwanted odors and ensuring a healthier sauna environment.

Individual bench elements are connected with through bolts guaranteeing a solid, silent connection. The bench frames are mounted to the walls using stainless steel brackets, which are fixed directly to the wall or to self-supporting bench end elements, offering flexible installation methods.
