Mine just have two press-studs close to the cross member. They are screwed to the wooden floor and the other part fitted to the mat. Works fine for me...others have used velcro.
same on mine. I got so feed-up with the mat getting bunched-up that I took it out. This has two advantages.
1) Does not get wet when it rains.
2) Useful when showing anyone who asks that a Morgan is made of wood
