I love this couch and it folds out into a fantastic guest bed. I tried every trick in the book to prevent the couch cushions from slipping; rubber matting, velcro, etc., but nothing worked. This is my solution. It may not look the best but it works perfect.
While I'm here, I would just like to add that I machine wash and air dry my leather cushions with no problem.
You could also use shelf liner that is made from rubber, I use it for my mattresses. Also there is a rubberized rug mat that you can use. It is placed under rugs to keep them in place. Just cut the size you need and place it under the cushions.

Use 20 inch wide rubbery shelf liners under cushions to keep them from moving on furniture.
Where can I find rubber foam matting to prevent cushions from slipping off a leather sofa?
I have a sofa and love seat that the cushions slide off of whenever someone sits on it. Then I have to lift the pillowtop back to slide the cushions up under it and back into place.
