Maybe something like this "L" shaped floor rocking chair? We had these when I was younger, they are pretty comfortable, do not take up a lot of space, and very easy to move around.
Also, floor sofas came to mind. Makes sense if you want something comfortable that is easy for one person to move around.
You might have to do a little research/comparison to find the right ones, but the links are some examples. :)
I got this chair back in 2010 and I still use it today.
