I was just wondering if anyone could give me a bit more information on the differences between the Jollie Soft and the Jollie Firm? I initially missed the fact that there were two versions of the two and now I'm tossing up which will be best for me, but I can't really seem to find much information on their differences, at least not in reviews and the website doesn't show a soft and firm option. One commenter suggested that they were all simply 'medium' firmness now - is that the case? Thanks!
