One hundred inches of height makes this the tallest structure in the group, which is what the climbing wall needs to feel like a climb rather than a step. Double slides, a splash pool and a basketball rim fill the 157.5 x 142 in footprint. Oxford cloth carries 350 lbs in total with each child under 116 lbs, for ages 3 to 10. Net weight is about 38 lbs. A blower of 480W to 680W is required and not included - worth buying at the upper end for a structure this tall, since taller walls lose pressure faster.
