It can be made from fiberglass or foam. Foam is your best bet. Its light, extremely mobile, and easier/faster to build.
I use a foam mat called best step anti fatigue mat. It works well. You can get it at sears, pepboys, and sometimes Wal-Mart.
Check out my build over at the Rpf. http://www.therpf.com/f24/mark-vi-ar...-heavy-128856/
I recorded everything I used and were I got it from.
I wouldn't mind sharing my knowledge if you chose to build one.
Best of luck
