This is a good one for the little kids, ideally suitable for up to 6 year olds. But it can fit about 8 kids on it depending on their size. It has a sun cover and a safety platform at the front. Also the barrier at the front will help to keep the kids in. Inside they have 3 Pilars as obstacles. A wow for the little kids and a bargain for the parents.
At this price you may want to hire another Bouncy Castle for the older kids at a discounted price.
