The VARILITE part number 077188 corresponds to the VARILITE Icon Back System Medium (Mid) Air-Foam Flotation Replacement Cushion & Cover, specifically configured for an 18-inch seat width framework.
Product Description & Anatomy
  • Air-Foam Flotation Technology: This core system eliminates mechanical pumps. It combines the pressure-relieving qualities of a multi-stiffness open-cell foam matrix with a physical two-way air valve. Opening the valve allows the foam to self-inflate, and body weight automatically distributes fluidly into the contoured segments. 
  • Anatomical Foam Sculpting: The internal foam is purposefully varied. It is constructed thickest and softest along the vertebral column to protect the sensitive bony spinous processes, transitioning to high-density, firmer foam along the lateral trunk walls to assist with core upright stability. 
  • Rollover Protection & Cover: The design includes an enhanced rollover cushion integrated directly into the top edge of the cover. This eliminates rigid contact if a user leans over or extends forcefully against the hard aluminum backshell pan. The outer cover is a machine-washable, breathable spacer knit fabric that manages heat and moisture. 
Seat & Frame Size Compatibility
To maintain clinical postural integrity, this replacement cushion is cut to mirror exact backrest configurations:
  • Cushion Frame Width: 18 Inches (Fits 18" horizontal backrest shells/pans). 
  • Backrest System Height: Mid-Back (Medium Profile). The mid-back height gives substantial lower and mid-thoracic support while leaving the upper scapula and arm areas clear for physical activity or self-propulsion. 
  • Shell Depth: Fits standard aluminum shells configured for mild contour support (not intended for the hyper-deep lateral "Deep" or "Extra Tall" series shells). 
Powerchair Make and Model Compatibility
Unlike power wheelchair seating components bound to proprietary mounting brackets (like Permobil’s Corpus system), VARILITE Icon Back Systems are universal hardware components. This cushion fits any powerchair configured with standard backrest rigidizer bars or vertical tubing canes.
It installs smoothly on the aftermarket backshells of these major power wheelchair makes and models:
  • Quantum Rehab: High-end powerbases running specialized seating frames, including the Quantum Edge 3 / Edge 3 Stretto, Quantum 4Front (Front-Wheel Drive), and J6 / Q6 Series equipped with adjustable back upholstery canes.
  • Permobil: Explicitly bridges to models running standard rigid back structures rather than contoured Corpus shells, including the Permobil F3, F5, M3, or M5 series bases when swapped to a universal cane setup.
  • Quickie (Sunrise Medical): Seamlessly interfaces with the Quickie Q-Series (Q500, Q700) power chairs configured with standard round back-canes or rigid seating plate configurations.
  • ROVI / Motion Concepts: Readily adapts onto heavy-duty or multi-function tilt-and-recline setups utilizing universal modular tracking rails.
