Designers Guide—Foam and Cleaning

June 2, 2016

Seating Capacity—The architectural standard for dining suggests that 300 square inches be allowed per diner.

However, some establishments may call for more or less allocation. For instance, fast food restaurants, quick serve coffee shops, diners, lunchrooms, or similar spaces can get by with less space per diner. On the other hand restaurants such as fine dining restaurants, pizza shops, Mexican restaurants, and many Asian style restaurants may require more table space for larger food items, special utensils, various condiments and sauces, and similar.

Foam can be measured by density and firmness (these are separate characteristics – e.g., you can have a very dense foam that is also very soft or you could have a very firm foam that is not very dense.) Because of this, it is possible to pick foam that will suit any need imaginable. Below are the characteristics of these two values.


  • Density measures foams longevity and quality.
  • It is dictated by the size and thickness of the individual cells that make up the foam.
  • Foams density is measured by how much one cubic foot of the material weighs. For example one cubic foot block of 3 lb. foam will weigh 3 lbs.
  • The denser the foam, the higher the quality and the longer the foam will last.


  • Firmness measures the physical feel of foam and how it resists pressure.
  • It is measured by seeing how much pressure, in pounds, it takes to compress a 15” by 15” by 4” sample of foam one inch with a 50 square inch circular indenter.
  • The value of that amount is called an ILD.
  • Firmer foam has a higher ILD while softer foam has a lower ILD.
  • Most ILD values range from 8 to 70 but can go as high as 150.
