The Extreme Dinosaur Bouncer with Slide is for ages 12 and younger and holds 12-15 children at a time. 18′ Deep x 22′ Long x 18′ High. 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 21’x25’x21′ area for set up. This unit has a bouncy area with a ladder to get to the slide. This unit does have a 15×15 COVERED bounce area.
