Best Foam Cushion with High Resilience Foam


High Resilience foam is the best foam to use for cushions and is the leading foam type if you are looking for high responsiveness for extra bounce and quick return action.

When it comes to what is the best foam for sofa cushions, High Resilience foam provides the most comfortable seat cushion and offers the highest longevity. It is an excellent quality foam that is used in many different types of expensive furniture and yacht cushions.

High Resilience foam is the heaviest foam on our list, at 3.0 lbs. per cubic foot, exceeding the minimum qualifying weight of 2.5 lbs. per cubic foot. It is very buoyant and resilient, giving it high responsiveness. That means that it will return to its original shape prompt after compression.

This is ideal for those that want more bounce in their cushions. With an open-cell structure, High Resilience foam is very springy but still offers sturdy support. It will also last a long time, between eight to ten years, as it begins to destroy and soften.

Luxary foam is a good quality foam for those looking to upgrade from High-Density Foam, the foam normally found in average foam cushions. It is ideal for those wanting a firmer foam.

Most Common Foam Cushion – High-Density Foam

High-Density foam is a medium quality industrial grade foam used in most average furniture because of its economic price structure. It weighs 1.9 lbs. per cubic foot and lasts approximately four years.

High-Density foam will return to its original shape after compression at a medium pace. High-Density foam will get softer over time as it deteriorates.

Cheap Foam Cushion – Polyurethane Foam


Polyurethane foam is the cheapest foam and will not be as comfortable or last if other foam types.

If you buy furniture from a home furnishings store like IKEA, chances are you are purchasing low-quality furniture for a low price.

That means that lower quality foam is being used, and it is more than likely Polyurethane foam. Polyurethane foam is inexpensive, low-quality foam. Over a short period of time, it will deteriorate and develop sink areas. When it does, it will not return to its original form. This foam lasts between one to two years.

It is also the lightest foam type, at 1.2 lbs. per cubic foot. It has a slower return action than other foam. Polyurethane foam is ideal for display furniture.

Wrapping Foam with Dacron

Foam can be wrapped in Dacron polyester fiber, usually between 0.5” – 1.5” thick. This is done by gluing the Dacron wrap to the top and bottom of the foam with spray adhesive. Dacron will make the cushion look puffy and feel softer.

Oftentimes store furniture will insert several inches of Dacron wrapped around the foam to give the illusion that there is a thick amount of foam inside. It also will make the sofa look extra comfortable and puffy.

However, if the Dacron is too thick it will compress over time and make the cushion lose its shape and will not return to form. That is why we recommend not going beyond adding 0.5”–1.5” of Dacron wrapping for foam cushions. You can find Dacron and spray adhesive here on our supplies page.
