Comfort and longevity are the first qualities that spring to mind when one considers the ideal characteristics of a foam cushion. However, the foam cushion that is ideal for reupholstering an antique chair may not be the same as the one that is ideal for an outdoor chaise lounge on the patio. Because of this, the ideal foam cushion will be one that is well matched to the purpose for which it was created. It’s possible that a cushion would need to be waterproof, or that it will need to have a certain level of firmness.
Key Terms to Know
When looking for a foam cushion, it is good to be familiar with some terminologies, as this will make the work at hand somewhat simpler. According to the Polyurethane Foam Association, density refers to the quantity of air that can be found in foam and is an essential quality to think about when selecting a foam cushion. When referring to foam, density is measured in terms of weight in pounds per cubic foot; the greater the density, the longer lasting the foam. The amount of “Indentation force deflection” a foam has will impact how comfortable it is to sit on.
It is a measurement of how many pounds of force will be required to compress the foam into its original shape. For instance, if a foam has an IFD value of 30, this indicates that it requires 30 pounds of pressure to indent an area of foam that is 4 square inches and accounts for 25 percent of the foam’s height. IFD readings may vary from 30 all the way up to 70 and indicate how firm the material is. Some types of foam used for chair cushions are referred to as having high resilience. This quality describes how fast the cushion will go back to its original form after being compressed.
Best Indoor Foam Cushions
Polyurethane foam is the most effective kind of high-density foam cushion for usage indoors. It is reasonably priced and has a firmness level that falls somewhere in the middle. When it becomes wet, it does not perform well, and when it is dry, it has a significant probability of developing mould and mildew. There are several different kinds of polyurethane foam, each with a different density; some of these foams are not appropriate for use as seat cushions. The optimal alternatives for seat cushions include a range that starts at 0.8 for regular foam and goes all the way up to 6.0 for high-resiliency foam.
Best Outdoor Foam Cushions
There are a few outdoor foam cushions that may compete for the title of best. Foams with open cells and foams with closed cells are the most prevalent types. According to Swanky Den, open cell foam has microscopic air spaces throughout, which allows air and water to freely move. When water is poured directly over a foam cushion, the water will pass through the foam and will not pool within the cushion.
Due to its resistance to the weather, this foam is an excellent choice for use on patio furniture. Because closed cell foam does not allow water to pass through and does not absorb it, it is a suitable material for use in flotation devices and seat cushions, both of which are often seen aboard boats.
The Best Foam Seat Cushion
When you are shopping for a cushion, be sure to keep in mind how you want to utilise it. If the cushion is going to be used inside on a regular basis, you should seek for polyurethane foam that has a medium density and a high level of resilience. Ask for a low IFD rating if you want a mattress that has a medium soft firmness. A waterproof and long-lasting construction is essential for an outdoor cushion. It is possible that it would not be used very often; hence, a medium density would be suitable. Patio cushions that are stuffed with closed-cell foam provide an extra layer of protection in areas that are adjacent to swimming pools.
