Liquid SunMate Foam-in-Place Seating (FIPS) is a direct custom-molding seating system to help correct or slow progressive deformities and improve body functions through fixed posture control. The FIPS liquid molds exactly to the body contour and cures into an open-cell viscoelastic foam. The finished cushion redistributes pressure evenly for management of tissue loads, and is easily modified to accommodate belts, harnesses, Pudgee, gel or air-cell inserts, or adjustable supports. FIPS is a quick, easy, affordable way to mold new cushions as a child grows. It can be used on its own or with a variety of fabric-finished molding bag systems on the market. Six different formulations and four unit sizes accommodate cushion molding for all ages and sizes.
