The Cherokee 38P has the classic two-facing-benches-and-a-table dinette. I've become annoyed that every time I slide out of the bench, I take the bottom cushion with me. Then I have to lift out the back cushion, place the bottom cushion, and return the back cushion.
I didn't want a permanent or semi-permanent solution. I hit on the idea of finding a nice, tacky drawer liner to place beneath the cushion, onto the plywood surface. The cushion was about 20" deep and most of the drawer liners I found were 12" wide. But I found this great 18" wide stuff at Bed, Bath, and Beyond
. The link happens to be to the white offering; I actually got "Graphite." Color really doesn't matter since it's not visible.
Hint: It's real easy to find 20% off coupons for Bed, Bath, and Beyond which sweetens the deal.
