The mat came waded up not flat in a box. Took some doing to get it lay flat due to it being fairly thin compared to other mats I have had. It has textured pieces on one side that when put on carpet prevent it from sliding. Because it is thin it tends to leave indentations from the wheels on my chair. Not sure how long this one will last.
Large mat works perfectly for my small area rug and hardwood under my office desk at home. My office desk chair no longer bunches up my area rug and wears on it. This is exactly what I needed.
Before I had a square 36"x48" mat. I wanted the lip so that I wouldn't roll off the front of the mat. However I found that the lip on this mat counts against the 48" and I was rolling off the back of the mat. Personal preference but I'd rather roll of the front and I returned it. Everything else was fine.
