Update On

Have you ever wondered how thick foam should be for dining room chairs? Choosing the proper foam for your dining room chairs is a more complex decision than you might have realized. It helps if you consider the height and style of your dining room table and chairs, and how often you use them. When picking out the best foam for your dining room chairs, you also need to consider the density of the foam and compression.

Dining room chair foam should be between two and three inches thick, but that is just one aspect of choosing the correct foam.

How Thick Should Foam Be for Dining Room Chairs?

How Thick Should Foam Be for Dining Room Chairs

Foam for your dining room chairs should be two to three inches thick. You want your foam to offer support and comfort, while being durable and long-lasting. Choosing the thickness of your dining room chair foam will depend on how often you use the chairs. It will also depend on the style of chair you have and the height of your table.

You want a medium-soft foam that has a good compression density. Your foam should be thick enough to provide comfort, but not so thick that you can’t fit under the table when sitting on it.

What are the Different Types of Foam for Dining Room Chairs?

There are many different types of foam that you can use for your dining room chairs. You can get open-cell foam and closed-cell foam. Open-cell foam works better on dining room chair upholstery. It allows air to pass through the foam’s free spaces, making it soft and comfortable.

Open-cell foam comes in standard thicknesses and offers good compression and quality at an affordable price. Closed-cell foam doesn’t provide good compression and can be hard.

Commercial Polyurethane Foam

This is the most common type of foam, and you can find it at very low prices. This type of foam comes in varied densities, so you can find a selection of foam to suit your needs. However, the quality of this foam is not ideal for dining room chairs that are frequently used as it is not durable or long-lasting.

High-Density Foam

High-density foam is the softest option and is long-lasting. It’s a good quality foam that keeps its shape well over time.

Memory foam

Memory foam offers good compression, and the high density means it bounces back well and is very soft.

Latex Foam

Latex foam is expensive but is also the highest quality foam you can get. It is long-lasting, and you can expect it to last up to 10 years.

High Resilience Foam

High resilience foam works well on chairs that get used often. This foam bounces back quickly and offers good support and stability.

Lux Foam

Lux foam is also known as Evlon foam and is for moderate to everyday use. It’s firm but comfortable, and it is a good quality foam that offers good longevity.

What is the Best Foam Density for Dining Room Chairs?

Who would have thought that choosing foam for your dining room chairs would be so involved? Let’s find out more about foam density so you can make the best decision.

What is Foam Density?

Foam density is not how firm the foam is. Instead, it has to do with how durable the foam is. High and medium-density foam feels the same, but high-density foam will last longer.

High-density foam is better if you use your dining room chairs regularly. If you only use your dining room chairs occasionally, then a medium-density foam will suffice.

ILD Rating Chart

Foam density rating is based on the amount of urethane and air in the foam. It is rated on a scale between 19 and 37. The more urethane the foam contains, the higher the density will be. These two-digit numbers are separated with a point to create the foam density score. For example, a foam density score of 1.8 means it is extra soft and more suitable for a back cushion. A foam density score of 2.8 means it is a medium soft seat, like a two-inch-thick dining room chair.

When choosing foam for your dining room chairs, look for a four-digit number on your foam. The first two numbers are the density and the second two are the compression. Compression is looked at in terms of the Indentation Load Deflection or ILD. A high ILD is better for a dining room chair that’s one to two inches thick.

How Thick Should a Dining Room Cushion Be?

A dining room chair cushion should be about two inches thick. If it’s less than two inches, it might not provide enough padding for comfortable seating. However, if the foam is more than two inches thick, the cushion may be too high. This will make it uncomfortable for someone to sit on the chair and fit their legs under the table.

When choosing the right foam thickness for your dining room chairs, you will need to consider the height of your table and the style of your chairs. Some states also have laws that set the thickness allowed for furniture, so you might not have a choice in the thickness of your dining room chairs.

What are the Best Types of Foam for Dining Room Chairs?

The type of foam you choose for your dining room chairs will depend on the chair itself and your budget. It would help if you also considered how often the chairs are used and by whom. There is a variety of foams to choose from, but here are the three best types of foam to use for dining room chair upholstery.

1. Latex Foam

Latex foam is the best for dining room chairs but is also the most expensive. It is a high-quality foam that offers good longevity. It is up to 20 times more durable than standard polyurethane foams. You can expect to use this foam for up to ten years before replacing it.

Latex foam can be natural, making it hypoallergenic and suitable for people with allergies. It won’t sag over time and will keep its shape. It’s permeable and you can easily mold it to the right shape.


  • Latex foam is long-lasting.
  • It is made from natural materials such as rubber trees.
  • It offers good support on a dining room chair.
  • Resists dust mites.
  • Does not retain heat.
  • Antimicrobial.


  • Latex foam can be synthetic, so check the packaging carefully.
  • Latex foam tends to be quite warm, so you will need to consider that when using it on dining room chairs.
  • Latex foam is also prone to imprints. If you choose to use latex for your dining room chairs, have family members sit at different places to prevent imprints from being left.

2. High Resilience Foam

High resilience foam works best for dining room chairs that are used often. It usually has a density of 2.5 to 2.8 and provides good support. This foam also bounces back quickly, even after being sat on for a long time.

This foam is flexible while offering good stability and holds up well over time. The buoyancy and responsiveness of this foam make it a great choice at a good price. It can be cut to size and will last years.


  • High-resilience foam is comfortable.
  • It offers good weight distribution because the particles inside the foam are different sizes, allowing them to move around when weight is put on them.
  • High-resilience foam is long-lasting and durable.


  • High-resilience foam can smell strange due to the off-gassing process. This is when the foam releases VOCs. So, you might not want a high resilience foam if you have lung issues or a sensitive sense of smell.
  • High resilience foam can be quite bouncy, which you might not want for your dining room chairs.

3. Lux Foam

Lux foam, also known as Evlon foam, is suitable for everyday use, making it ideal for dining room chairs. This foam is an open-cell foam that is firm, but comfortable. It’s durable and high-quality with a density of about 2.2. This foam can last five to seven years and is affordable. Lux foam has good buoyancy and will retain its shape.


  • Lux phone is heavy, which means it lasts longer.
  • It holds its structure well.
  • Requires less maintenance.


  • This foam can be bulky.
  • It is not a soft foam.


Choosing the best foam for your dining room chairs is more complex than you may have imagined. You want a foam that will save you time and money. But, it should also be comfortable for those long family dinners.

Here is a recap of what you need to consider:

  • Foam density
  • Foam compression
  • Foam thickness
  • Space between your dining room chairs and the table
  • How often you use your dining room chairs
