The double high bar went down well packed and is easy to assemble. Convince the material used and the design and the distance between the posts and the diameter of the horizontal bars is well matched to the child's needs. It is stable enough that 3 children can rumturnen it simultaneously and it also keeps (normal weight) of adults. The rods can be mounted at different heights and are therefore largely fit for every age group and requirements: the smallest hanging himself with his hands on the horizontal bar in the lowermost position, the bigger kids hang upside down with the knees on the pole in the highest position , And all of them have their fun.
