Types of Foam Cushions

Various types of foam and fillings can be used for different seats. From boat seats to indoor couches, everything uses some foam. Here is a small list of different types of foams that may help you understand what best fits your needs.

1. Fabric Backed Sew Foam

Fabric Backed Sew Foam

This type of foam is frequently used in upholstery. But, it is not for filling cushions. Instead, fabric-backed foam adds a layer to the cushion to increase softness. You can also use it to soften hard edges, like wooden chairs. 

The base material for this foam is also polyurethane, like many other foam cushions. The cloth or fabric backing makes the foam easier to work with. You can easily glue, staple, or sew it to other surfaces with it. 

This type of foam is seen in motorcycles or golf cart seats. Padded surfaces of bags or diaries may also use a thinner variety of this foam. This foam is usually found in thicknesses of ½ or ¼ inches. This makes it easier to bend and fold. Thus, they are used to add textures or patterns on top of items. An easy example of this is a handbag with a quilted texture. 

2. Dryfast Foam

Dryfast Foam

Dryfast foam does what the name would suggest. They are made of open-ended cells, which have larger spaces between them. This allows for an easy outflow of air and water. 

They are best for use in outdoor cushions or seats. This is because they do not retain water content and require nearly no maintenance. In addition, such cushions can be used in all weather, including rain and snow, without any worries. 

Dryfast foam is also made to be anti-microbial. Since they are intended to be used in wet conditions, it is essential to prevent fungus and mildew. This type of foam is also in great demand for use in boats for the same reason. 

It is easy to be fooled by fake versions of this foam. However, since it is so highly in demand, you will quickly see imitations of it too. One easy method to test for authenticity is pouring water. Water poured over this foam should flow straight down without anything being retained in the foam. If it spreads out from other sides, it is not a true Dryfast foam cushion.

3. Polyurethane Foam

Polyurethane Foam

This is the most traditional form of foam used, especially for couches and chair seats. This foam type, too, undergoes an anti-microbial treatment. However, since it is used in household items, the cushion will likely get wet. In such situations, it is best to remain protected from fungal growth or mildew. 

Polyurethane Foam can be of more than one type. However, the most commonly used ones are medium- and high-density ones.  

Medium Density

Medium-density polyurethane foam is also quick in drying. The anti-microbial properties make it more attractive as well. In a lot of cases, people pick this over a Dryfast cushion. That’s because medium-density foam provides more cushioning while drying off quickly at the same time. Boat cushions (cabin) or garden seatings will often see this type of foam. It is seldom used for indoor furniture.

High Density

High-density foam works the same way as a medium-density one. The only difference is that it has less give when weight is put on it. They are used in everyday, indoor objects that are likely to see a higher amount of usage. Sofa cushions, ottomans, settees, etc., use high-density polyurethane foam cushions the most. 

Some high-density foam can also be anti-microbial. But, it is not recommended for use in outdoor settings, as it won’t dry off as quickly. On the other hand, this foam can last a very long time. Higher-density foam comes in medium, firm, or extra-firm levels. The higher the density, the firmer the cushion.  

4. Fiberfill (Polyester) 

Fiberfill (Polyester)

Poly fiberfill is not a foam by itself but another type of cushion filling. These are most commonly used as fillings for throw pillows or a specific back cushion on couches.

For pillow fillings, they usually already come stuffed and sewn with this inserted in them. You may choose to add a different cover or layer on top.

This type of insert is resistant to fungal growth by itself and does not cause allergies. It is also machine washable, making it a hit amongst most households. The fiber does tend to ball up in the wash, but this can be easily fixed by hand. 

How to Choose the Best Foam for Seat Cushions

1. Use of the Cushions

It is important to know the intended use of the cushions so as to choose the best quality.

Outdoor cushions for instance need to be waterproof and should withstand extreme weather conditions.

Also, you need to determine whether the foam cushions will be used on the sofa, couch, or dining chairs so as to choose the right firmness and thickness.

Dining chair cushions may need 1 or 2 inch thick cushions with a firmness of about 30 to 45ILD while sofa cushions may need to be about 4 to 5 inches thick with a firmness of 30 to 35ILD.

2. Compression Rate (Firmness)

The compression rate of the foam cushions also plays a very significant role in regard to usability.

It determines the firmness of the cushions in regards to how they hold up when weight is applied.

The compression rate is indicated as Indentation Load Deflection (ILD) or Indentation Force Deflection (IFD). It ranges between 8 to 70 and the higher the rate, the firmer the feel of the cushions.

Thus, you should use the values indicated on the foam to determine the firmness or softness of the foam you want to purchase.

3. Foam Density

The density of the foam indicates its quality. The higher the foam density, the thicker and more resilient the cushions will be.

The density usually ranges from 1.5 to 2.5 pounds per cubic foot. The higher densities range from 2.0 to 2.5.

Select foam that will suit your needs in regards to cushioning and stability.

4. Durability

The sofa cushions foam should be made from quality materials that are durable and resistant to wear and tear.

Ensure the foam you pick is durable so that it will last long without flattening after being in use for a short time.

5. Type of Foam

When buying foam, make sure you know what type of foam you’re getting. Polyurethane foam is better than latex for example because it’s more resilient.

In addition, it’s resistant to stains, can be cleaned easily, and has an excellent bounce back if you sit on it hard. It also lasts longer and gives you better support for your back when used for back sofa cushions.

6. Thickness

The thickness of the sofa foam is an important consideration when deciding on a furniture purchase.

A thin cushion may not provide adequate support for your back and arm, leading to discomfort or even injury.

On the other hand, too much padding can make sitting in one spot uncomfortable after extended periods of time.

Therefore, consider the thickness of the foam depending on what you want in regards to your comfort.

FAQs – Best Foam for Sofa Cushions

1. What is the best foam to use for sofa cushions?

The best foam to use for sofa cushions is a high-density, open-cell polyurethane foam.

This type of foam offers the most comfort and durability. Also, it provides firm support that will keep your body aligned while sitting on your couch.

From the list of foams reviewed above, high-density open-cell polyurethane foams include Mybecca foam and FoamTouch upholstery foam.

If you are looking for something cheaper, but still comfortable, then you can opt for an egg crate or low-density polyurethane foam

These foams provide less cushioning than the high-density variety but they also cost less money

2. How thick should sofa foam be?

The right thickness of sofa foam depends on your individual needs and preferences. If you have back problems or are simply looking for more cushioning, then thicker foams will be best for you.

But if that extra padding isn’t necessary and you still want some support and comfort while sitting down, thinner foams might work better for you.

3. How can you tell if the foam is high-density?

You can determine whether or not foam is high density by;

– Press the foam with your finger. The high-density foam tends to recover slowly when pressed since it’s more resilient than low-density foam.
– Comparing the weight to other types of foam. High-density foams are much heavier than low-density ones
– Looking for a “high-density” label on the packaging or in descriptions online
– Comparing the price. Of course, high-density foam is of higher quality than low density; hence, it’s priced relatively high.
– You can also tell if it’s high-density by looking at how tightly packed together its cells are
– Finally, the high-density foam will be more durable and last longer than a lower-density type

4. Is high-density foam good for a sofa?

Yes, high-density foam is good for the sofa. This is because it is very durable and will last a long time.

Also, it provides good support for your back, neck, and head. In addition, the high-density foam doesn’t retain heat as some other materials do. This means that the temperature of the room won’t affect how comfortable you are sitting on it all day long.

Most importantly, this foam is customizable. You can easily cut it into any desired shape with a utility knife or electric saw.

5. How long does high-density foam last?

As the aforementioned, high-density foam is very durable and can last for years and years because it is very resilient.
