I have a chair in an environment of only static collision objects. But the chair is bouncy from every surface it touch. So it wil bounce higher and higher and i cant find what setting i forgot to set

My basePhysicsWorld has gravity (0,-20,0);

my chair:

chair.friction = 0.9;
chair.collisionFlags = AWPCollisionFlags.CF_CUSTOM_MATERIAL_CALLBACK;
chair.mass = 40; (tried different settings with no result)

For the rest I only create rigidbodies with mass 0 and collisionFlags AWPCollisionFlags.CF_STATIC_OBJECT

try to set chair.restitution to less

Thanx for the reply. I already found the problem I was adding the rigidBody twice to the AWPDynamicsWorld so every force was also added twice to a body.
