The build quality is absolutely fine for the price and seems durable. The cords could still go to a higher capacity if you take the case of strong wind on the grass or the dike, Watt dares etc. Here is my warning comes for parents and children, this mat is absolutely not for children. If the wind is so strong, you will forces occur, which the child can fling through the air just, better take a smaller mat 1.4 m so here. For adults a little strength training is popular with a lot of wind already.
