I've only had it two weeks so don't know if my computer chair wheels will eventually leave dents in this mat as happened to previous mat.  I do like the way my chair glides over this mat, and it looks really great on the carpet letting the color of the carpet show through.  The size is absolutely perfect in front of my computer armoire.  It is easy to pick up, with no pointed prongs to stab into my hands.  Definitely better than previous mat which was a folding one that  split at the fold after 18 months.  The carpet care person who cleaned my carpet in 2009 told me I needed a mat under the chair wheels so I purchased the folding one for ease of picking up as that man also said I should vacuum under the mat occasionally.  So far, the Floortex is great!
