The Relief-Care« Pro Mattress System uses advanced Surface Cut Technology to create a clinically effective support surface. SCTÖ enables Blue Chip to produce a therapeutic dual-zone PPF« Pressurized Polymer Foam support surface with varying features and properties. This engineering advancement provides proper pressure redistribution that offers the patient a clinically effective mattress with low interface pressures. This design absorbs and redistributes patientÆs weight to provide greater comfort, maximum support and proper pressure redistribution around bony prominences. Covered with a Vyvex-I« top cover and a medical grade vinyl bottom cover. Vyvex-I« is a low shear, fluid proof nylon material which is anti-microbial, fire-retardant, stain resistant and washable. The foam core and cover meet Federal Flammability Standard 16 CFR 1633 for fire retardancy. Mattress can be manufactured to meet California Technical Bulletin #129 and Boston Fire Code 1X-11 when specified. SCTÖ technology creates an advanced pressure redistribution support surface that provides unlimited comfort zones.
