We should have bought this at least a year ago! The fake wood flooring had worn thru to the subfloor at that desk and there was a hole where the chair was. Made it difficult to move the chair but this mat covers the hole and it's much easier to move. We've finally gotten approval to replace the floor but that mat will remain to protect the new flooring.
Since I use a 6' folding table for multiple tasks this allows me to move sideways from one task area to another not just pull up to desk edge. For my setup bigger is a whole lot better.
This is an ok mat. Serves it's purpose and is the perfect size. Not real fond of the way the chair wheels "sink" down into the plastic making for a slight aggravation to move but the mat does slowly recover and does not stay dented.
