Katsuno-style Pelvis Tightening Cushion Pelvic Correction Cushion This cushion is designed to correct posture. I purchased it for office use to reduce back strain and improve posture, as well as to correct slouching. I've been working from home, so I placed it on my chair and used it for a few weeks, but I'm selling it because I'm using something else. It shows some signs of use, but in my opinion, it hasn't lost its shape much. It has low resilience and made it easy to sit with my pelvis upright. ■Color: Red ■Size: Width 31 x Depth 42 x Height 8.5cm Weight 0.3kg ■Materials: Filling: Polyurethane foam Cover: (Pile fabric) 80% cotton, 20% polyester (Knitted fabric) 100% polyester ■Weight: Approximately 300g The three-layer structure of low resilience, high resilience, and rigid urethane tightens the pelvis and makes it less tiring to sit for long periods. It will be placed in a waterproof bag and shipped simply.
