The Jacob's Ladder is for all ages and measures 20′ Deep x 15.6′ wide x 12′.3 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 23’x18.6’x15.3′ area for set up. Try your skill on our Jacobs Ladder. This unit comes with 2 ladders so you can race to the top! Race to the top using one of the two ladders!
