How do you stop matts/rugs moving on carpets??

[tufty7]

We have one of them dirt master door matts that soaks up the wet and damp from our shoes and dog,

Has anyone got any ideas about how we can stop it creaping away all the time?? is there a product or idea that works and does not damage the carpet as it a constant struggle to get it to stay where it should and i don't want it to become a trip hazard .......... Thank you in anticipation .....

get stick on velcro stick it to the floor and then the matt to it and you can get non slip rubber grips from dunelm

you can get double-sided tape for rugs, places like Homebase or B&Q I think.
