EXGEL EXGEL Yuka Puni Fit Pelvic Support Chair I purchased this six months ago for working from home, but I am selling it because my workplace changed and I no longer use it. I used it with care, so it is in beautiful condition and is a high-quality item. Sitting on the floor can cause fatigue, such as leg numbness, a rounded back, and strain on the lower back. The Yuka Puni Fit prevents pain in the lower back and buttocks with its lumbar support and appropriate height, allowing for comfortable use. The cushion is approximately 415mm wide, 390mm deep, and 255mm high (including the backrest). The seating surface is approximately 290mm deep and 129mm high. It is the perfect height for a cross-legged or seiza (kneeling) posture. Thank you.
