DYNAMIC SAUNAS Canadian Hemlock S-Shaped Sauna Backrest, Ergonomic, 2-Pack

A sauna bench is a flat board against a flat wall, and after ten minutes your lower back knows it. A loose backrest is the smallest change that turns “sitting in the heat” into “settling in” – and it changes the look of the bench as much as the feel, because two matching curves at either end of a bench read as seats. This Dynamic Saunas pack holds two S-curved frames in pale Canadian hemlock, each a row of round crossbars between two curved side rails, that lean between bench and wall without brackets or screws.

The maker makes them for its own infrared cabins, where they rest at a slight angle against the heater panels, but the frame simply leans, so it works against any flat sauna wall. It is rated for up to 275 lb (125 kg) and arrives assembled. The listing gives no measurements and mentions no anti-slip pads, so expect to nudge it back into place now and then.

Tip: Drape a folded towel over each backrest before you sit – bare skin sits on cloth in a sauna, and the towel keeps the pale wood clean.
