Solid Wood Backrest for Infrared Sauna provides comfort and ergonomic support, and it protects from encountering the infrared heat panels. (Infrared heaters directly heat the body rather than heating the surrounding air, like a traditional sauna.) The backrest is designed to fit the natural curve of the back, which helps prevent discomfort and promotes relaxation. It’s equally effective in the horizontal and the vertical positions. At the same time, it helps avoid contact with the infrared heaters. This backrest was distributed by Salus Saunas, made of natural Canadian hemlock, without stains or toxic finishes, about 16” W x 24” L. It is high-temperature and moisture-resistant, with an S-shape for back support and a 300 lbs. capacity. New was over $100, a bargain here for next-to-new and available for local pick-up in San Rafael, cash, Venmo, or PayPal.
