Posture Correction Cushion

I purchased this on Amazon, but it doesn't seem to fit my body. I'm listing it here because I'd rather give it to someone than throw it away. I've only used it 2-3 times, and there are no noticeable scratches or stains.
Please note that this is a used item stored by an amateur, so there may be minor scratches. Thank you for your understanding.
No returns or exchanges (3N).
