I bought this to use at my crafting table. It not only makes it easier to roll around in my chair but it makes it much easier to pick up small items that fall off the table. This is the third one of these mats I have purchased and they are well worth the cost.
The plastic in the chair mat is not rigid enojugh. The rollers of my office chair sink in it a little and it is hard to move the chair from one position to another. However I like it's appearance.
