The Gift Box Jumper is for ages 12 and younger and holds 10-12 children at a time. This unit measures 15’x15’x15′. With the set up of every inflatable we ask for 3ft of extra space around the outside, so for this item we would need a 18’x18’x18′ area for set up. This GIANT birthday present is sure to be the highlight of your party! This unit includes a BIG area for bouncing. And who wouldn’t love to see a big birthday present in their own back yard! This unit does have a 15×15 NETTED bounce area.
