As soon as I sat down in my office chair after putting this glass mat down, I knew I would never again go back to those traditional plastic one's. Your chair will glide effortlessly across it - no more of my chair being "stuck" or "sunk" into the mat. It's also a much more modern and clean look as opposed to the ugly plastic office mats. If you're worried about whether or not it will hold your weight (plus your chair), trust me, IT WILL. This thing is SOLID.
