The material that makes up the mat, rubber industry - kindly given on the website - a material that is designed for extreme pressure loads and therefore can withstand a lot. It is flexible, is good for, but goes quickly back to the starting position. The mat itself is fairly thick and so well insulated, without one standing gets a eieriges feeling. She has a width with which one can make good floor exercises. Especially field circuit where you need to the sides often leaves more space, look good with this width. The color I find enjoyable. Is not my favorite blue, but pretty close. There is a smooth and a corrugated side. I use the smooth side to be on the other side as a floor. On the smooth side sliding hands, feet, arms, legs very well, without being too slippery. With the risers they can be transported well. The mat was delivered quickly and well packed with the curl, less sensitive side towards the outside. In this way I had when delivered no impressions of the risers on the sun side (happened to me with another mat). In return, the mat has easily erected by rolling out at the ends. I could leave, as I have them rolled up very tightly with the curl face inward when not in use or transport.
Initially, an imprint of a unit was on one side to see where the mat was probably firmly clamped for reeling, and grooves, the solid compression probably not yet stabilized state. If both are now gone.
The traces of the riser when he presses on the smooth side, remain temporarily, but not permanently. Dumbbells, etc. I have not tried. But what definitely is not going to have sharp objects. The mat smelled initially from close to rubber, but has also given.
So overall, the mat is comfortable, well insulated against cold floors, intercepts pressure loads without having to by pressing the ground, is dimensionally stable and elastic. It favors the sliding of individual links on the ground, without being slippery. If the manufacturer could decide it differently to roll around or mitzugeben appropriate instructions to let them cure properly before it is mechanically clamped and rolled and - what to me rather little means - memorize a nice logo, they should with this mat easy gymnastics studios conquer. I pull from no star, because that's what I have to complain about, has not significantly disturbed the functionality of the mat from the start and has now also disappeared.
