Ages: 12 and younger. 10-12 kids can bounce at a time. Bouncer Dimensions: 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. Additional Information: This unit is a 15x15 COVERED area. There is netting around the sides of the unit, so it is an enclosed 15'x15' area. Customer will need to supply: An electrical source within 100 feet of set up will need to be available upon set up of the Crayon Bouncer. This unit requires one motor, so it will need only one electrical outlet.
