Abstract
Embodiments of play systems having multiple curved structural members are disclosed. Play systems illustratively include a first quarter of an ellipse, a second quarter of an ellipse, a third quarter of an ellipse, and a fourth quarter of an ellipse. Each ellipse quarter has first and second ends. The first, the second, the third, and the fourth ellipse quarters are oriented approximately vertically relative to a surface such that the first ends of the ellipse quarters contact the surface and the second ends of the ellipse quarters are above the surface. The first ends of the ellipse quarters are optionally spaced further apart from each other than the second ends of the ellipse quarters.
