Mat does not stay secure on carpeted floor. I am constantly having to move and re-adjust it. It seems the backing spikes are not pointed or long enough to hold it securely in place. It is also very soft and casters cause indentations. For what it cost I expected much more.I'm Not a happy customer.
This item arrived the very next day and was delivered perfectly flat and ready to use. But the mailing label was stuck directly on the mats and was VERY difficult to peel off with out creating a sticky mess!
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!
