Don't believe the title. Read the description. I am very happy with what I received. It is sufficiently rigid to provide a rolling surface for my chair. Good value.
Was I supposed to order something for underneath this mat? I almost fell when I stepped on it and it slid. It keeps sliding. How is this for hard floors? Horrible waste of money
I got tired of looking at the clear plastic I have purchased in the past. This wood style looks nicer. I can't attest to its durability yet but it is nicer in appearance than the clear ones.
I love the black; it looks great with the carpet. It doesn't have spikes on the bottom so it does move around a bit but I'm okay with that. Mine came rolled up tight but it unrolled easily and flattened out with no problem.
