We have trouble with door mats at handyman towers.
Whatever we try, mats just move around & won't stay put.
So, I'm investigating mat wells cut into the carpets at front & back doors.
Seems simple enough, a mitered frame and you drop a coir mat in the hole. We have a thick carpet & underlay, so it would need to be a thickish mat.
But what size to make the hole?
Is there a BS or ISO mat size? Or can you buy it cut to size.
I don't want to cut the carpet & install the frames, only to find in two years time I can't get mats the right size.
