Yes One frame fits all size cushions. I found out you can even stack a small cushion inside a medium cushion and a medium inside a large cushion and it makes it even softer on the face. I think the is the best mask I have tried so far.

Thank you for your help. It is a very comfortable mask I am surprised there are not that many people using it. Maybe because it so hard to find one.

I can not find it on there site.

I have been using the Ascend full face mask by sleepnet. Does anyone know of any place to buy replacement cushions? I also was wondering what other people who have used it thinks of it. Thank you.
