I've been looking at separate cushions for my Compact Jr. The ones that came with it are nice but smaller cushions make it easier to access the underseat storage.
What I've seen in stores is like Goldilocks and the Three Bears....
Too big, too small, too thin, etc.
But yesterday I found some that were just the right size, soft enough for sleeping, and on clearance. Had to visit two of the chain store locations to snare the necessary half dozen of them however.
They were at Meijer, a Midwest version of Wal-Mart.
If any Compact Jr owner is interested in my one piece cushions I've posted them in the for sale
forum, along with a 4x7 foot piece of foam from an old pop up camper.
