This is a great single piece unit that has the ability to add on a second of the same design on the opposite side to make it a dual lap obstacle course. Hop inside to start the race through many of the popups, once you get to the back climb up the stairs to the 9’ slide and slide down to win the race.This exciting game is sure to keep kids and adults alike outside occupied for many hours giving them plenty of exercise! The Single Lap is a great design to fit many backyards and during the summer use the slide with water to make this unit a waterslide.
