I thought this one would work in my new condo but the padding under the rug is new and spongy and my casters are just making depressions in the mat. I should have gotten one that was harder.
I called Staples before placing my order and asked what the measurement was for the piece that slips under the desk. I was told it was 24" so I ordered the mat. The piece actually measures a bit more than 25". I decided to trim it to 24" to fit under my desk because I liked the rest of the measurements for the chair area. Now I find that the chair rollers have 'dimpled' the mat and there are depressions that catch the rollers. I weigh only 131 lbs. and that should not be excessive weight to form the dips which require a good push to move the chair. My carpet is med. pile.
What can I say. I have it at home and the chair in which I sit as I write this is on it. Works good. Always am pleased with purchases from Staples.Bob Munsey
