Quote - All great ideas!  I dinked around with the magnets, but will be checking out the gravity morphs.  I am also working on a poofy leather chair, and want to get it to look not so rigid when my character is sitting in it.  Thanks!!

A chair with "sat on" morphs would be great, I've tried with a number of models to do this with magnets but the problem often is that there aren't enough vertices (if any) in the front edge and seat. I got best results using group editor to create a material zone for the  seat cushion, making it invisible and then replacing it with Trekkie Grrrl's morphing pillow, though matching materials can be an issue. 

For body parts you might want to check Adam Thwaites Natural Bounce it has butt morphs too
