Crash Pad Density - Home Climbing I am in the process of planning to convert my garage into a climbing wall. I was wondering what kind of density foam I would need for the crash pad?

The height of the climbs will only be between 2m to 2.4ms off the ground.

I am thinking of having the foam cut into segments so I can pack it up when the garage needs to be used. To keep it all together I could some form of rubber overlay that can be rolled up. What do people think of that idea?
