I ordered 3 floor mats and they were not shipped in boxes. They just had a label slapped on them and put on a UPS truck. The plastic got bent from being upright and they have taken a couple of weeks to flatten out. Pick these up in the store if you have that option.
I ordered this chair mat to replace an identical mat that after several years had begun to crack. I bought it online and it was delivered to my door quickly and painlessly. It works well. The one concerning thing is that it indents quite a bit under my chair's wheels. The indents go away after being off the mat for a while but I'm thinking I might buy something stronger and thicker next time.
This is the second chair mat I've bought from Staples at this price point for use on medium-depth household carpet. The previous mat lasted just three years before cracking badly enough to be unusable. This mat is clearer and looks thinner but after several it seems to be holding up better. My rolling chair hasn't worn any grooves into it. I wish it were a heavier more durable plastic but am hopeful that it will last longer. Note to other buyers: if you buy this mat rolled up let it warm and soften for about a day before trying to unroll it. Once you get it unrolled with the smooth side upward let it relax for another day. It will flatten fully but it takes a little patience.
I bought it in person and really like the price but it was too flimsy for the carpet. My chair and weight made big indents into the mat and hard to roll my chair around. It would flatten on its own. If I didn't have carpet. It would probably work better. I returned it.
The chair mat I bought is not nearly as durable as I would have thought. My chair is making indents in the material very easily and quickly. I hope it lasts as long as the last one I had (about 10 years).
