Good size but not thick. The weight from the chair and me cause indentations in the mat so the chair does not move as easily as it could. Invest in the thicker more rigid mat if you have the money.
Everything was great and appreciated all the help by Adam and the other young man that helped in my decision making and I chose the right chair for me. Thanks again!!!
Nice LARGE thick mat! First one came in damaged but Staples QUICKLY replaced it (2 days). Works well on short shag carpet. I'm 200 lbs and my chair rolls smoothly without sinking it. I've had cheaper thinner mats that didn't work well. I would recommend this mat to others.. Good product value.
While this chair mat does provide coverage to prevent carpet wear my chair wheels create impressions in the mat and it makes it difficult to roll around easily. I'm not that overweight and it seems this mat should either be thicker or more durable so the wheels of my chair don't get stuck.
