Better than a donut and Ergoseet for office chair, not for keeping in the car
I had injured my tailbone and sitting was only making life worse. You're probably there if you're reading this. Get this one. There are different styles and sizes, but this is the brand you are looking for.<br /><br />Tall memory foam donut helped some, but not enough. Right from day 1 I could tell the difference with this one. I went from getting worse to better, it still took a few weeks but I got there and it was tolerable with a week for me, your milage may vary but you'll like this for your office chair, tv chair, or even in the car but don't keep it there in the summer according to the instructions and other reviews.<br /><br />It's weird squishy and kind of weird but fun to sit on without the cover, but I was worried about my cat eating it so I put the cover on anyways and then it doesn't squish around as much. I liked it better with no cover, but it still works great with it on.<br /><br />The size is pretty big for this one but it will squish into a smaller chair if you get the wrong size or need to use around the house in different chairs. I even brought it to my sleep number bed to sit and watch tv during the first week.<br /><br />Good quality, I'm a bigger guy and it's held up all summer great. I bring it in the car for longer trips. For regular driving I recommend Ergoseet (old or new model, if you can find them) because of the heat issue, but for temperature controlled areas this is the real deal.
