I use this mat to go under my computer chair so the rolling back & forth on the carpet will ruin the carpet. This is the third one I have brought in the last 3 years and they just do not last the start cracking in the center and the hole gets bigger and bigger and pieces start falling off the mat. Should be more pliable.
Smaller size is preferable for a home office. The other two models available at Staples may be great for a commercial business office but the smaller one is perfect for my smaller home office.
