The main thing I like about this is the subtle and the little notch at the back, as it does an EXCELLENT job at relieving the pressure and pain from my tail bone. I also like that this stays secure and doesn't wiggle around like the donuts do. I'm also petite, so I like that this also lets me sit a little higher up, so "standard" chairs are more appropriate for my height. Kind of like a "socially appropriate" booster chair for a petite adult ;)! Plus it alleviates some pain I feel after sitting too long. The pillow is fairly comfortable. It feels like you're sitting on a firmer pillow. It is great to help both my injured tail bone/coccyx and gives me a nice little height boost as I'm petite! I also love the subtle dot design!
