Arrived by Staple's free delivery to my home. Was delivered flat in very cold weather. Allowed to lay flat at room temp for 2 days then removed adhesive labels and cleaned with mild soapy water rinsed dried and now lays and appears as expected. This is a replacement for a previous 5 year old mat in my home office.
After reading other reviews I was a little concerned about ordering this product BUT I have been using it for a little over a week now and I think it is absolutely great. I needed to replace an old mat that my chair wheels kept making little divots in. I couldn't roll the chair easily. This mat has totally solved that problem! No more divots. My chair rolls easily even after not moving it around for long periods of time. I have about 1" thick carpet/pad and every other mat I have tried has sunk into the carpet. This mat is thick enough that it doesn't sink. Some of the other reviews have said they had problems getting the mat to stay in place. I don't seem to have that problem. The grips on the bottom stuck to the carpet nicely and the mat has not moved from where I put it down. One note of caution though...This is a thick mat. Make sure you order a size that you will not have to "trim".
Just had 2 of these matts delivered to my house rolled up and stuffed into a a giant box loaded with Stapes There has to be a better way of shipping these things. I've beought this brand and model before and they seem to last 3-4 years which isnt a long time but better than the cheaper models. The one thing I did notice is they are about 2 inches smaller than they were the last time I bought them; I guess any way that a company can save a few pennies helps keep the cost down. Hopefully I will get the same life out of these as their predecessors!
