text: Upon first use it felt very comfortable to sit on. Over time though (week or two), it became rather firm. Not as soft feeling as it once was. Now it is difficult to sit on it for more than a couple of hours to do my computer work. I'm finding it necessary to use another cushion under it. It's a nice size that fully covers the seat part of a desk chair. I like the fact that it is even clear across the cushion without any raised areas on the sides like some I've seen. Do make sure you turn it once in a while (like turn clock wise; don't flip over to other side) so you're not sitting on the same spot all the time.
