Types of Sofa Cushion Filling

  1. All Foam Cushion Filling

This type of filling is normally made of a high-density foam core. A softer layer of intricate foam, like an egg crate, covers it, then wrapped in a polyester fiber. To prevent the feathers from pushing through, downproof ticking envelops the whole thing. It is a popular choice because it offers a very firm seat and shows the least possible wrinkles in the fabric upholstery. All foam cushion filling requires less maintenance, making it ideal for busy people.

  1. Spring-Down Cushion Filling

Spring-down cushion filling is normally the second option. Made with a core of coiled spring, it is the second-softest cushion material. A foam box surrounds it and a thick layer of polyester fiber wraps the whole thing. It is then put into a downproof cover full of polyester and down fiber. The down provides a touch of softness and loft while the springs give a strong feel. If you are looking for a reasonable amount of cushiony feel without worrying abouthow to make it look great, choose the spring-down cushion filling.

  1. Blendown or Down Plush Cushion Filling

 Your third option is the blendown or down plush cushion filling. Made with a thinner foam core covered much a thick layer of polyester fiber, and then covered much a much thicker layer of poly-fiber and down blend, it is the most luxurious and softest cushion fillings. It feels so soft and cushy that it can be like a pillow. Thanks to its relatively thin foam core and larger amount of down!

Materials Used for Sofa Cushion Filling

Foam is the most common sofa cushion filling material and is available in different densities.

  • High-density foam offers a firm cushion but may be too hard for some people.
  • Low-density foam has a medium or soft firmness and easily depreciates.
  • Memory foam conforms to your body so it supports your body well, which is perfect for those with joint and muscle pain.
  • High-resilient density foam (HR) are tougher. It is more resilient to sagging and wear and may last for 14 years or even more.

Feathers and Down                  

Cushions with feather fillings are perfect for those who prefer softness. Feather fillings are cheaper and area mixture of chicken or duck feathers. Down are from the lush feathers on the lower abdomen of geese. Down-filled cushions are more expensive. Waterproof covers protect feather fillings from spills.


Available in various densities, polyester is economical. However, it flattens out easily.

  • Soft polyester is smooth, bouncy, and durable.
  • Faux-down polyester imitates the feel and look of down and is cheaper than down. This filling is recommended if you or other members of your family are allergic to feathers.
  • Cluster-polyester has tiny balls of fiber. It is one of the most long-lasting and durable polyester fillings.
  • “Ply-a” soft polyester is not firm and does not spring back when you sit on it.


To keep foam cushions from slipping, batting is applied in the foam. This is available in two thickness sizes:  25.5 and 42.5 ounces. It is normally created from:

  • Wool comes in layered or needled form. Needled wool is used to cover sofa springs because it is stronger. Layered wool wears easily.
  • Cotton may prod through the sofa, so a cotton-polyester blend is better.

Whether you are buying a modern design sofa, make sure to choose the filling that suits your needs and lifestyle. Remember, the cushions are part of the sofa, which is an essential piece in your modern living room.
