OMG. This is the best thing ever. I have purchased other mats that have come apart. This one is about 3 months old and it has not moved nor does it show any wear.
[...].Using on light industrial carpet with pad. At [$] each (purchased two) thought they would be thicker and more resilient. Chair wheels cause depression in mat.
Used in home office with minimal thickness w/padding. Have not found anything great about it except the price. I believe a piece if 1/4" plywood with carpet tacks in it would work better. It won't lay flat shifts position does not support my 200 lb. self and office chair.
