Below is the real pictures.
This trampoline is mostly for kids play and the customer also buy some playground product for kids play. Every city has many big shopping malls and people like to spend the weekends in the shopping mall, so I think it is a very good idea to use the center area for trampoline and kids playground.
The trampoline is enough for about 20 kids play in it at one time.
The customer use the outside area as the birthday party area and they will put some kids tables and chairs for kids birthday party and also for the parents waiting outside.
