I love having this mat under my chair. I spend a lot of time sitting at the computer and because i am disabled to be able to move the chair easily to get up and sit down. I had managed to break the wooden leg to my chair in trying to push away and up to the desk and it cracked the leg of the chair so that the roller would not stay and it was getting dangerous for me to use once i got the pad i was able to use tape and fix the leg on my chair and with the mat do not have to worry about falling anymore! I really do wish i could have afforded one several years ago! But thanks to Staples i was able to find one that i could afford and they even carried it for me!
This mat has rug grippers but not the nasty finger punching ones other products have. It only took about two days to settle in and not walk around as I move my chair. The delivery service was great.
