Abstract
A stackable step stool having a platform and obtusely angled legs where the design of the stackable step stool allows the stackable step stools to be stacked on top of one another in an alternating manner. The platform is typically rectangular with rounded corners. A raised ridge surrounds the top surface of the platform. The support frame consists of two inverted U-shaped legs. Each of the inverted U-shaped legs has a center portion with two obtusely angled leg portions extending from the center portion. The center portions of the inverted U-shaped legs attach to opposite sides of the platform. The obtusely angled legs are angled away from the platform such that the stackable step stools can be stacked on top of one another in an alternating manner. The stackable step stools are stacked on top of one another with the upper stackable step stool being displaced by at least the width of the legs. Additional stackable step stools can be stacked on top of the stack in an alternating manner. By stacking the stackable step stools in an alternating manner the stack stackable step stools preserve floor space and increase the stability of the stacked step stools.
