Foam HR

All foam is defined by its weightfirmness, and cell structure.


Generally, heavier foam lasts longer. However, density has nothing to do with firmness. For example: a dense foam can stay very soft for decades, while a very firm foam could break down after a year or less, dependent on usage.  
Foam weight is measured in pounds per cubic foot. 1 cubic foot equals a 12''x12''x12'' square box. Fill that box with 2 pounds of foam and you have a 2 pound piece of foam.


Foam firmness is rated numerically. Lower numbers mean softer foam and higher numbers mean firmer foam. Our foams range from 21 (super soft) to 90 (super firm). Technically, these numbers represent the ILD (indentation load deflection) or IFD (indentation force deflection).

Cell Structure

Conventional and Resilience (HR) are the 2 major types of cell structure. Unlike their conventional counterpart, HR foams have many interlocking connections between cells. This HR technology allows this foam to retain its original feel over time while conventional foams will break down much quicker.

3 Questions To Ask Yourself When Choosing The Right Foam For You

How long do you want the foam to last?

How thick does it need to be?

How firm (or soft) would I like it to be?

First ask yourself, "How long do I want the foam to last before is starts taking a set and breaking down?" A good point of reference is if you were to use these foams as a seat cushion in your family room or as your mattress in your home where it will get several hours of use per day. In this case, the Everlon series will last about 6-8 years. The HR's and Q's come with a lifetime warranty* and will always feel the same. The best foams we have are the HR's. They have both the best cell structure and are heaviest. If your use does not require daily use, you can use a less dense foam.

Another FAQ is "how thick does it need to be?" remember, the whole point of foam cushioning is that you don't want to hit bottom when you sit on it. A sofa cushion is generally 4"-6" thick of a medium firmness. A breakfast nook chair pad is limited to 1" to 2", so it should be a firm and HR type foam. How firm or soft would I like it to be? Samples of 10"x10" are available if you are unsure of what you are looking for in a foam for a minimal cost. Whatever you pay for samples is fully applicable to any future order. 
1) Drifast: This foam has large cells allowing water to percolate through the porous foam. Dry fast does not retain water like other foams and this allows it to “dry fast”. It is an excellent choice for pool areas, boats, yachts or outdoor areas where water comes in contact with it, as it will drain out.
