As an experienced trampolinist, I want to say that low black ceilings are very bad for controlling rotation at height and safety in general. For children who have come to have fun at this trampoline center, there are many entertainments such as inflatable pillows, slides, foam cubes and other things. Trampoline nets of good quality (I know from experience) with different stiffness for different weight categories of visitors. Prices don't bite either. I would like to add that there were no instructors in the trampoline area, who must ensure that visitors do not violate safety regulations. Because of this, children rushed around the hall, risking their own and others' health.
