We have the mat under a desk and part of it had to be slid under our bookshelf. It sometimes "bubbles up" on the corner. Quality is good for the price. The plastic seems very pliable. Our older one seemed a little more stiff but I don't know if that is better or not. It cracked after about six years of use (which is very good in my opinion.) Perhaps the pliability of this one will make it a better mat. I really can't say but I'll be happy if it also lasts five or six years.
We purchased a crystal clear chair mat at Staples Palm Desert a week ago and found it was the perfect fit so we went to get a second one at the Staples Palm Springs. They did not have the same size mat on display but an employee was kind enough to go check in the back and found one!! We are very pleased with both the mats and the customer service!
