I guess “mat” is a pretty generic term. The mats we use are 4X5 3/4 to 1 inch think. They are not easy to roll up and they are not “easy” to pick up and carry around. Don’t know what they weight but more than a 50 lb bag of feed that I do know. Most people would consider me to be pretty strong.
Channel-lock pliers work ok as do vise-grip. But they don’t make a “handle”. You have to grip both which can be awkward and difficult for a lot of people. I used to use them. C-clamps make it MUCH easier for the average person and hand strength with heavy thick mats.
I use vise-grip if I am only moving/adjusting the odd mat. Vise-grips should be in everyone’s tool box.
