This is a sauna cushion inspired by the concept of seated meditation (zazen) at temples. By entering the sauna in the zazen posture, with your pelvis upright and your hip joints stretched, you can efficiently absorb heat. It can also be used as a neck rest during breaks or for meditation. It has a high heat resistance and dries easily, making daily care simple. It uses materials with excellent antibacterial and deodorizing properties. Size: 260 x 110mm (Depth: 125mm) Weight: Approximately 330g Material: 100% Polyester (Filling: 100% Polypropylene Pulp) * Can be washed completely. I believe there is no damage other than the box, but please refrain from purchasing if you are sensitive to minor imperfections due to personal storage.
