Poufs come in a variety of materials, including leather, cotton, wool, and synthetic fabrics. Your choice will really come down to personal preference, as well as what kind of look, feel and durability will best suit your needs. If you’re looking for an outdoor pouf, you’ll want to ensure choosing a material that can withstand the elements; and if you’re purchasing for a kids room, you should factor in the risk of spills or it becoming stained.
