Saddle maker's chair cushion. Bagu Mat Premium. Can be used on chairs, floors, floor chairs, and sofas. Supports sitting posture. It has been used a bit, but it is generally clean. Everything in the photos is included. Jointly developed with a charismatic beauty therapist and a saddle maker, this posture mat allows you to sit comfortably for long periods. The concept of the Bagu series, "sit for long periods, stably, and with ease on your lower back," remains the same, but it has been upgraded to an airy material and structure that pursues even more "comfort." The highly breathable material is resistant to stuffiness and can be washed, so it's always clean. Furthermore, it's lightweight and easy to carry, making it easy to move from your telework space to the living room. It can also be used outdoors for camping, parks, and watching sports.
