Distinct types of carpet require different types of cushions. The type of cushion you should use with your carpet depends upon the type of comfort that you seek. Not everyone requires a cushy feel with their carpet. It depends where you're using the carpet and your comfort level. Typically, a softer feel is what one wants in a bedroom. A cushy carpet feel is not necessarily desirable throughout the entire house.

For a person not steady on their feet having a cushy soft, bouncy feel may be dangerous. Using the wrong type of cushion can also void the manufacturer's warranty.

There is no standard for comfort or feel. It is very subjective. That’s why it’s important to try out the carpet and cushion package before making a purchase. It is also not a good idea to let the salesperson determine what feels right for you. The store may offer a ‘package price’ including cushion, but that doesn’t make the package the one you really need. What feels soft to one customer may feel hard and uncomfortable to someone else. A person’s weight will also influence how the carpet/cushion combination feels under foot. Price has little to do with the feel, but the less expensive the cushion, the more air in the product and the less material.

When purchasing a cushion, you should be looking for how it feels under your carpet. Carpet cushion manufacturers offer a warranty on their cushions.  It is wise to ask your flooring professional to explain the warranties. Once you find a cushion that feels good under foot, talk with the professional about the type of cushion. Two things should be important to your purchase: The feel of the carpet/cushion and the performance factor. Performance has to do with how the cushion will perform over time.

There are three types of carpet cushion. The three types include: Foam, which is short for polyurethane foam; rubber, short for sponge rubber and fiber, which is short for felted fiber.

Cushion varies by weight, often called density, and thickness, or the amount of force required to compress the cushion. The more material you add to the cushion, the denser the material. The density of the cushion is very important. It determines whether the cushion is soft or firm.

Prime urethane foam is much like the cushioning utilized in furniture, mattresses and car seats. It is fabricated with two liquids which create a mass of foam that is then cut into sheets that become carpet cushioning. This bonded polyurethane foam (often referred to as simply ‘rebond’) is created by adding chopped and shredded foam pieces then gluing them together. Following that, they are rolled and sliced into the different sized pieces needed.

Typically, bonded polyurethane foam is fabricated from materials that might otherwise end up in trash and tossed into some nearby landfill.  Old carpeting cushions can be recycled a second time and become new cushions once more.

The other foam, called froth polyurethane, is made from liquid ingredients which are adhered to the back sides of some styles of carpets.  This carpet is generally reserved for use in commercial applications.

There are two types of rubber cushion, a natural or synthetic material that is heat cured and produces a waffle pattern. This usually has a luxurious feel and is particularly used for residences. There is also a flat sponge rubber which is very dense and used for large-scale commercial applications and with loop or Berber type carpet.

Felt cushion is made of synthetic fibers and produces a firm feel underfoot. This type of cushion can be used under any type of carpet.

Again, the type of cushion is dependent on your type of carpet and your particular comfort level. It is important to keep both in mind while choosing a cushion.
