I bought this so that I could easily roll my computer chair around to various files in my office. I found that my chair made indentations when I sat so that it was more difficult to move than before I bought it. I plan on taking it back to Staples and if there's nothing that does what i want just do without.
Perfect flormat...looks great on my hardwood floor...can't even see it.. But keeps the chair from flying away from me...I couldn't emagined how nice it is to have...don't know why I waited so long. Very good quality . Worth the buy. Don't hesitate
