Different Types of Foam Filling For Cushions and Sofas
Foam filling in furniture is the core and very important to choose the right one for the application. Different types of foam filling have been engineered to float, prevent mold and mildew, drain water, and withstand daily wear. If you want to select foam with attributes that are compatible with the way you plan to use it.
Polyester Fiberfill is not really foam, but somewhat blown polyester fibers. It is an affordable option, polyester fibers are a common stuffing for pillows and deep seating back cushions. Fiberfill is non-allergenic, tough, and resistant to mildew. It can easily wash in the machine, but the fiber can bunch up in laundering. So, try to use your hand to smooth it back out.
Medium Density Polyurethane Antimicrobial Foam
Medium Density Polyurethane Antimicrobial Foam is suitable for seating and mattress applications because it is a traditional foam option with medium firmness. Polyurethane foam soaks up water when it gets wet, but the antimicrobial treatment on the foam helps to avoid the growth of mildew and mold as the foam dries out. The antimicrobial foam should be used where it is unlikely to get wet or should be wrapped in a waterproofing layer, like Silk Film, or Cushion Wrap, before being inserted in the cushion cover.
High-Density Polyurethane Foam
This polyurethane foam is the same basic product as above mentioned the Medium Density Polyurethane Antimicrobial Foam, but with a higher density. The higher density attribute makes this foam more resilient and more suitable for daily high-traffic uses. High-Density Polyurethane Foam is available in firm, medium, and extra-firm firmness levels and typically lasts up to 12 years. Also, some high-density foams are antimicrobial as well. This foam is best for high-use interior applications, upholstery seating, such as sofa cushions, and for interior settee and berth cushions in dry boats.
Dry Fast Open Cell Foam
Open-cell foams make a calm, comfortable, and cool seating cushion or mattress, and it has open pores that allow air and water to flow through easily. Dry Fast is a fine-quality open-cell foam that is formulated with an antimicrobial agent to avoid mildew and mold. When paired with an outdoor cushion fabric, the open-cell foam creates a virtual maintenance-free cushion in rain, sun, and snow. These characteristics also make this foam great for boat cockpit cushions.
Closed Cell Foam
Closed Cell Foam resists moisture absorption, and this foam is made from PVN which is three times firmer than polyurethane foam so it is also a more expensive option. Closed Cell Foam is great for flotation applications like floating cockpit cushions and it is also a great choice for commercial boat seating.
Fabric Backed Sew Foam
Fabric Backed Sew Foam is a thin layer sheet of polyurethane foam and it is perfect for upholstery applications. Its features include a spun-bonded polyester backing that holds adhesives very well and makes the foam easy to glue in specified areas or places.
