VPF. CREATING THE WORLD’S CLEANEST FOAM WITH OUR PATENTED PROCESS.Instead of producing foam in an open environment that emits harmful contaminants into the air, we manufacture our beds using Variable Pressure Foaming (VPF), the most eco-friendly process in the world.VPF emits zero emissions into the atmosphere because of the unique closed design of the chamber. The air that leaves our VPF chamber is sent through carbon filters, which removes harmful chemicals and makes the air cleaner than when it came in. VPF is the only foam creation process that exceeds the requirements of the Clean Air Act.Our VPF process is free of harsh chemicals, creating foam with incredibly low Volatile Organic Compounds (VOCs). Because every variable is computer-controlled inside of the VPF chamber, we create foam with stronger cellular walls to enhance its durability and comfort. Any waste from this process is 100% recycled internally.
