<p>A three-dimensional nonwoven web having a regional, bulk density of less than 0.04 grams per cubic centimeter, a top-side base surface that defines an x,y-plane and at least one macroscopic surface feature extending out of the x,y-plane wherein a macroscopic surface feature is characterized as a feature having an apex that extends at least about 1 millimeter above the x,y-plane of the top-side base surface is provided. The macroscopic feature maintains a height of at least 1 millimeter above the x,y-plane of the top-side base surface under a 1.2 kPa load (Pf ) and results in contact of an object resting on the macroscopic feature such that the percent contact area of the nonwoven web with an article resting on the macroscopic surface feature at a 1.2 kPa load (Pf ) is less than 50 percent of the bulk area of the nonwoven web supporting the article.</p> |
