Summary: If you’re planning to make some improvements to your couch, it’s important that you understand what’s inside the couch before you start.
If your couch foam is starting to wear down, it’ll natural disintegrate and lose its ability to maintain weight and pressure. Sagging cushions can turn any piece of furniture into an old and tired product. But, replacing the foam is an entirely different story.
This guide will walk you through the basics of what’s inside a couch, so you can determine how to proceed if you’re looking to do the task yourself.
Polyurethane
A product of the petroleum industry, polyurethane is commonly found in most couches today and is the most common type of foam. Available in an array of grades that indicate the shelf life and the various stages of firmness, you can find polyurethane from foam distributors, specialty stores, and retail stores. Because it contains petroleum, it may not be considered an eco-friendly product.
Foam Types
Foam is rated by its expected years of use. For instance, you can find foam that’s rates as high resilience, which is a high-quality type of cushion foam with a density of 3 pounds per cubic foot. Or, latex foam, which is comprised of rubber, as opposed to polyurethane, can have a density anywhere between 3 to 15 pounds per cubic foot. Lastly, you have memory foam, which is a type of polyurethane foam but manufactured to produce a high-density product.
Down or Poly-Fill
Cushions that are wrapped with down or poly-fill can provide a variety of benefits to the user. They tend to give off the look of a down-filled seat cushion but have the comfort of a standard piece of foam. The inner core of foam often determines how firm or soft the couch cushion is.
