Hi, The weight limit on the Spray N Splash 2 inflatable itself is 200 lbs. This accounts for one user on the climbing wall, and one user on the slide. 3 Additional users are allowed in the splash pool. Users shall not exceed 100 lbs each. Depending on the angle of the ground, water may accumulate up to approximately 10" However, we recommend running the sprayer system at the lowest flow required to lubricate the slide, in order to save water and make the process of drying and storing easier.
