The mat is just as the name describes "economical". This mat should not be used on carpet unless the carpet is a very low pile like an indoor-outdoor carpet.
Using this in a home office on low pile carpet but with a thick pad so there is lots of give underneath. The last one I got fell apart after 18 months heavy use. This one is clearly much higher quality and I don't think I'll need to use the life time guarantee it comes with. (Still nice to know it's there.)
