I love Olfa and also have a mat I ordered from Salem (custom size) and it is really holding up well!
Some of the matts are gridded on both sides..and they usually have a different color on the other side also...for instance, my Fiskars is violet on one side with dark lines and pinkish on the other side with dark lines.
