I was curious, as would be the mat packed and shipped. This is not fact not trivial. All in all: highly professional. The mat itself is completely flat, and does exactly what it should: it allows the movement of an office chair. She is with me on a short nap carpet. Even the crossing of the edges is not a prob. mThe first impression in terms of stability is very good. How long does it actually holds, but must be for a longer period do not put more to the test. A mat from another manufacturer only lasted about 2 years.
Supplement: The mat is for a year in (excessive) use. It shows no traces of wear to date. Continues to be very satisfied. Absoolut empfehelenswert value product.
