I only weigh 145 lbs and the floor mat only seems to last 1 year. I don't know what the longevity should be but I feel it should last longer that than before cracking and breaking.
The mat came to us rolled up and secured with packing tape directly on the product. As a result the mat has sticky strips that until we take the time to try to remove dirt is going to stick to those strips.
The title was easy to find when searching for the product. The description offered was concise and accurate. I've only used it for a short period of time so I cannot attest to its durability - - Here's Hoping!
Loving the no lip. No more rolling off the edge and getting distracted when rushing to meet a deadline. Bought this style for a new office make over. Not disappointed. Our other mat was cracking due to a high pile carpet.
