Yes, when unboxing your Razer Goliathus Chroma | RZ02-02500 or Razer Goliathus Extended Chroma | RZ02-02500 for the first time, the mat needs to rest on your desktop surface for a few hours before it fully flattens out. You may place a book or similar flat object on the surface to help it flatten. However, do not place to much weight on the lighting frame.
