I have the typical Papasan frame. I had no idea they could come in different sizes; given that the frame does not vary. Thus, I bought one that I assumed was the correct size. Looking at your picture above;picture one twice that size . Guest laughed out loud when they walked in and saw it, all asking, "Why? Why is it so huge?" 
The only good thing was your willingness to help me return it. As a lady just two months from my 83rd birthday and debilitated and weak, it would have been impossible to get it back in its box (in fact, I am sure the air was sucked from it and a machine stuffed it in) but you permitted me to stuff it into big black bags and tape it shut.
