Densified fiber is an excellent choice and is the industry standard for outdoor custom cushions. Water will easily drain from your cushion which prevents mildew and bacteria. This makes it the perfect filler material for your outdoor custom cushions. It is also well-suited for indoor cushions.
Densified fiber is a special blend of poly fibers that melt at different temperatures. The Poly fiber blend is layered into a slab with fibers that melt at a lower temperature layered against fibers that melt at a higher temperature. The whole slab is then compressed and baked in an oven until the fibers are fused together. This creates a firm surface that can be cut to any size. The poly fibers repell water which makes this an ideal filler for outdoor custom cushions. Cushion Pros has been using densified fiber for years with excellent results.
At Cushion Pros we use environmentally friendly BioComfort® foam from Prestige Fabricators. BioComfort® foam is made with Cargill soy base polyoil which comes from the oil in the seed of the soybean. This process of using soybeans does not affect food stock supplies and helps reduce the dependence on petroleum based products used in foam manufacturing. This is one step towards a cleaner environment. The Prestige Fabricators foam manufacturing process also includes filtration beds which contribute towards a friendly green environment.
Foam Filler is used exclusively for indoor use and is not recommended for outdoor use.
CertiPUR-US approved foam are:
- Low emission VOCs for indoor air quality
- Made without ozone depleters
- Made without PBDEs
- Made without mercury, lead or heavy metals
- Made without formaldehyde
- Made without phthalates
All of the "Bio Comfort" foam that is used will be a 1.75-1.85 density. Density is a key flexible polyurethane foam specification. It is an important indicator of foam performance with regard to comfort, support and durability. It is also an indicator of the relative economics of the foam. Foam density is not weight. It's actually a measurement of mass per unit volume for a cubic foot of foam.
All of the "Bio Comfort" foam that is used is a 21-29 lb firmness or IFD depending on thickness. The higher the number the firmer the foam will feel. In upholstered furniture, foam firmness is described using a standard measurement value called IFD - Indentation Force Deflection. An IFD number represents the pounds of force required to indent a foam sample by a specified percentage of its original thickness. Specially designed equipment is required to measure IFD. In most cases, a 50 sq. in. round indentor plate is attached to a vertical piston-like cylinder having a precisely calibrated stroke. Following the standard procedures detailed in ASTM D3574, firmness is measured on foam samples having a square surface area of at least 15" x 15." Surface firmness is measured at 25 percent sample indentation -IFD. As an example, using a 4" thick sample, the 25 percent IFD reading would be made while the foam is indented to 3" height under the piston foot plate, 25 percent deflection of the sample height.
