HOW TO PICK THE CORRECT FOAM

We sell a variety of foam. When you look on our website you will see a four digit number used as a descriptor, below is a break down of what those numbers mean in terms of quality and firmness. As always, we are here to assist. If you have any questions please call us and we will be happy to guide you in making the best choice for your project.

QUALITY

The first number you see on a piece of foam is often referred to as Density. This is misleading. It actually indicates "Quality."

1.1 Is a lower quality value product used for crafting and some light use furniture projects.
1.8 is a medium quality foam. It is often used for upholstery projects often used in DIY projects. It is not the highest quality but professionals will sometimes use 1.8 for customers concerned about price or when the task does not require a higher end foam.
2.6 is referred to as "Forever foam." This is the foam most people select when investing in a project that they expect to last for many many years. This is the "blue foam" professionals use when hired to fix your favorite chair or couch.

FIRMNESS

Foam firmness is valuated through a test called Indentation Load Deflection (ILD), also known as Indentation Force Deflection. The numbers below indicate how much force or weight it would take to compress the foam by on inch.

10lb = ultra soft. Used for cushion backs, crafting and foam toppers. The firmer foams are used more when comfort and structural integrity are required
34lb = Medium firmness. This is often used for couch cushions, dining room chairs, lounge chairs and loveseats. This foam is also utilized in boat cushions and Often used interior boat seating such as v-berth cushions. 34# can be used for seat backs as well. For sleeping, 34# is the most firm I personally will enjoy.
45lb = Firm. This is a firm foam and predominantly used by the professionals . It promotes structural integrity so cushions do not sag or dip. This is often topped with a softer foam or batting to give a cushion a softer feel while offering support.
65lb = Extra firm. The name says it all. This is the foam you want when you need substantial structural integrity and a very firm foam. Your tush will know you are sitting on firm foam for sure.

DACRON ADD-ON

We are happy to install a dacron wrap to your foam for a small labor charge + the cost of the dacron fabric. This addition will make your cushions look "plump" and "full". However, the addition of Dacron means that we cannot ship the order vaccum packed and the total cost of shipping can get extreme. As an example, shipping five cushions that are 20x20x3 with dacorn from Maine to California could cost as much as $85. The dacron we use is 1 inch thick when uncompressed. When compressed under your cushion cover its closer to a 1/3 of an inch. If you add dacron to the top+bottom of a cushion it adds about 0.5-.07 inches of loft to the foam.
