The King Arthur with Water Slide and Pool is for ages 12 and under and holds 12-15 children at one time. This unit measures 18’Wide x 17’Long x 10’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’x20’x13′ area for set up. The King Arthur Combo has a LARGE bouncy area and push overs throughout. There is a tunnel that takes you to the water slide that ends in a pool! Heavy Unit- A minimum of 42″ wide gate is needed to access set up location. You do need to supply a garden hose and water supply for this unit.
