I'm selling a chair I no longer use because I bought a new one. There's some wear and tear on the fabric, but no major scratches or stains. Of course, it functions perfectly. If anyone is interested but finds new ones too expensive, how about this one? 【Product Description】 The MediCore Posture Mini received the highest rank of A+ in "MONOQLO (November 2023 issue)" and won the "Best Buy" award for posture support cushions! It guides the pelvis to the optimal angle, reducing the burden on the lower back and back. It sinks in the front when you sit and rises in the back, using the "lever principle." Reduces the burden on the lower back. "Cradle structure" that doesn't fix the pelvis. US and Japanese patents obtained. Patent number 5502901. Mesh fabric for excellent breathability. Easy to sit on and less tiring. Twice the cushioning of conventional models (compared to our products, such as the Relief Grip). Heat-resistant, making it ideal for cars. Large hole to prevent tailbone pressure. Guide cup to prevent sliding forward. Easy to carry with the hook on the back (regular size only). The shape fits the pelvis and buttocks for an improved hold!
