This is a very rare cushion designed to help you sit upright. My sister gave it to me, saying I should use it because my posture was getting bad from using my smartphone and computer for long periods. I threw away the box, so I don't know the official name. I haven't been using it much lately, so I'm selling it at a low price, considering the shipping cost. You sit on it, and it supports your posture, making you feel like you're sitting up straight. Please consider it if you're interested.
