I was disappointed that if I sit for more than a few minutes in any one spot the wheels on the chair create impressions deep enought that I then get stuck in them. It's very difficult to roll out of them when moving sometimes I have to get up and move the chair. The impressions do go away in a short time once the chair is moved. My other issue is that this mat would NOT stay in place which amazed me since it had 3 table legs on it (from an l-shaped configuration). So several times a day it would creep several inches under the table and I'd have to take the chair off of it and fight to pull it back into place. I had been afraid to drill it as it is hard plastic and I thought it might crack a lot. I finally figured my daily struggle with it was worse than some cracks so I took the chance. Once it was in place I drew around each of the 3 table legs with a sharpie then took the mat to the basement for drilling. I first drilled with a small bit in the center of each sharpie circle then used a 1 1/8" hole drill to accommodate the 1" round table legs. Worked like a charm no cracks and nice smooth edges. Now the table legs keep it securely in place.
Love the quality of the mat - lays nice and flat and protects our hardwood floor. I only wish it was wider as I'm constantly rolling off the edge when retrieving items from the filing cabinet....
Staples apparently can't be bothered to pay for a box to ship this item. It had cardboard wrapped partly around it and taped directly to the exposed mat. I spent about 20 minutes trying to get the tape off before I gave up on getting it all off. Worse the tape leaves such a sticky residue I haven't been able to get off that my feet stick to the mat everytime I walk on it.
The hard floor chair mat was delivered the next day and was exactly what was ordered. The product seems durable and once put in place relaxed and laid flat after a couple hours on the floor.
