I have tried several different types of cushions and this is by far the best. You can sit on it and totally relax without feeling like you are going to fall off of it. As soon as you sit on it you have total comfort and relief.
Overall it is a good pillow. I would rate a 5/6. I have tail bone issues , back and other problems and felt this would be a decent try. Memory foam is great, I can take off cover and wash it and it's soft enough. Shape was decent would have liked a little wider and longer. I had a concern with the depressions in the pillow as I realized that once you sit on it the weight of the person presses down the foam and the depression area almost disappears.
Okay the pillow seat cushion is definitely comfortable to sit on during a shift at work. Especially when you are sitting on an observation. As I work in a hospital I cannot take photos. It is very easy to take with you when you move to another area. It does not lose it shape. It does not go flat. It does help to reduce back and leg pain while sitting. The only thing I would suggest is a little larger diameter for the size.
I sit at a desk anywhere between 8-11 hours per day. My chair can be very uncomfortable as the day goes on, especially with a bad back. This cushion feels awesome! I have only been using it a few days now, but I am noticing a difference. It has cushion and give, not hard like some other cushions that I have tried. I like that it is not putting pressure on my spine allowing me to remain comfortable throughout the day. So far so good, I am happy!
I received this package very well wrapped and it unfurled easily. This cushion is very comfortable and has a fair bit of bounce to it. I've been using it for a few days at my computer and I haven't experienced any discomfort or back pain. The material is a fairly decent quality and it's breathable so it doesn't get sweaty or especially smelly. The foam cushion insert is not too firm, not too soft. So far I've really liked having it. My cat has also liked me having it because she likes to curl up in the donut center and sleep when I'm not at my computer lol.
