The Sports 7in1 is the newest combo style to join the Bouncing Off the Walls family, and is sure to be a hit at your next party or event! The 7in1 combo features a slide to the outside (dry only), bouncing area, obstacle pop-ups, climbing area leading to the slide, and two basketball goals. One main way the 7in1 differs from the 4n1 combos is that the 4n1's have a slide which is completely situated inside of the unit, so the children never have to get out of the inflatable while playing at the party. Each version is great. We have over 70 themes to choose from for all of our 7in1, 4n1, and large bounce house rentals. Many are not even posted on the website, so be sure to call if you have a particular theme in mind for your next inflatable party rental!
