Cushioning elements may include a first material layer, a second material layer, a plurality of components (e.g., polymer foam components) that are located between the first material layer and the second material layer. Some of the components are secured to the first material layer and the second material layer, and other components are unsecured to the first material layer and the second material layer. In some configurations, the various components have different thicknesses. In further configurations, at least one of the component defines a plurality of apertures that receive other components. |
