Questions (some) asked in this review are too soon to answer (i.e.. cracking discolouration construction. Used in my home study/office. Chair slides smoothly on the chairmat
I've tried all range chair mats. This lighter weight construction does not have a seam down the middle thus making it easy to roll over mat. Also the wheels on the chair do not get stuck in the middle eliminating the possible crack that usually winds up happening there. It has a good hold onto the carpet & has good quality construction. A good mid range mat. Highly recommended
