Important to me was the width of 1m, as the normal mats with 60cm offer little room to the side, at the slightest rotation is located on the bare floor, that does not happen here. Slightly longer would be nice, 2m or 2.20m instead of 1.85m, so you do not stretched too far protrudes, but since 1,85m is the standard for all manufacturers, you have to stand it.
Unfortunately, the material is relatively hard, especially in the size (185x100x1,5cm) comes as quite a weight together, to take away the mat therefore good for fewer, you should then set but rather a lighter second mat.
The price for the Airex mats is indeed steep, but the performance offered is the price worth it.
