There are many organic materials which, over time, have been used as upholstery fillers. Some of them are durable and some are really prone to mold and bacteria infestation. Mold and bacteria are given an ideal medium to grow when many organic types of material become wet or even just moist due to excessive humidity. When that happens, it presents problems for the owners. Bacteria can cause illnesses, and as for mold, there are many people who have differing levels of allergic reaction to them. That is aside from the fact that some molds are really toxic.
Some of the organic materials used for upholstery filling may surprise most people: animal hair, including the top-of-the line horse hair, cotton, kapok, loose wool, dried tree moss and dried grass, and tow (a fiber derived from flax). Aside from animal hair, most of these materials may no longer be used once infested with mold. People who are about to buy used upholstered furniture should ask exactly what the fillings are made of, especially if they suffer from some form of allergy. Of the many types of organic filling, only few are now used by modern furniture and upholstery shops. Most modern upholstery now only uses only cotton, wool, kapok, and various synthetic fillers.

Modern upholstery filling is now usually made of latex or urethane foam materials wrapped in some sort of wool, cotton, or synthetic padding to smooth it out and ensure that the upholstery cover does not touch any section of the frame. wholesale upholstery supplies is most often used because they make excellent no-compress padding and also because of their relatively affordable price. Dacron is a trademark for a type of polyester that has high tensile strength and resistance to stretching, and also resists damage due to abrasion and exposure to chemical bleaches. It does not make a good medium for bacterial and mold growth, making it a good choice for furniture upholstery.
Dacronis available in many weights (densities) and thicknesses. Usual padding thicknesses are anywhere from 1′ to 1 1/2″. They are usually sold in rolls and sheets. Resins and hardeners are removed from Dacron sheets used for indoor furniture to allow a softer and more consistent feel. Some of these are made with hollow-fill polyester fibers that easily spring back to shape. These make excellent wholesale upholstery supplies.
Some Dacron fibers are made with soft sheeting which can be easily removed so they can also be used as pillow fillers. These fibers also make ideal filling for stuffed toys. While Dacron sheets used to pad outdoor furniture have resins and hardeners which make them a bit rougher but allow them to drain well; they are also resistant to mold and mildew.
Dacron has much better shape retention than fillings made of down fill or low density foams. That and its low price make Dacron the filling and padding of choice for many upholstery shops and furniture manufacturers; that includes those who may be members of such organizations as the North American Home Furnishings Association
