What is it made of?
The first thing you think of is ice chest cooler foam.  Incorrect.
Our molding is made of high density material, but still lightweight. (Light blue)
The cells are very small and hard to see, not like cooler foam. (white)
No plasters, mud, or concrete finishes are needed.  It is ready to paint.
Is it soft ?
 It mounts high at ceiling level, out of contact from chairs, vaccums etc.
It can be dented.  It can also be repaired very easily.  Just take painters caulk and put on
damaged spot and wipe off with a flat surface like a credit card.
