Display was incomplete. Sales representative wen to back and brought out this one. We would have preferred a thicker plastic. Chair wheels sink into the plastic but otherwise it works fine.
Bought it for my wife to put under her chair while she works at her sowing machine. Just today she told me the edge sticks up (presumably from the weight of her sitting on her chair) and one time not realizing the edge was sticking up she caught her toe on it (ouch). Shudda paid more for the better one.
give this mat 3 stars its ok not very durable over carpet chair likes to sink in on the mat have to pull yourself to get out of your sink hole.....but overall nice mat.
