The Invacare Contoura back cushion (Part #OH11006 / 11006) is a specific molded-foam seating component engineered for Invacare's power wheelchair seating platforms. The "OH" prefix typically denotes the molded, vacuum-formed vinyl (or leatherette) variant of their seating line.
Product Description
  • Material & Build: The cushion features a contoured, molded polyurethane foam core designed to match the anatomy of the user's back. The vacuum-formed outer shell is typically wrapped in a fluid-resistant, wipeable vinyl/leatherette material for quick clinical sanitization and easy cleaning.
  • Contouring Support: It utilizes integrated, gently curved lateral "wings" or side contours. This structure offers mild-to-moderate torso stability to keep the user centered without needing independent, bolt-on lateral hardware pieces. 
Seat Size Compatibility
Invacare Contoura backrest pads are labeled according to the specific frame size they are intended to cover:
  • Width & Height Frame Profile: Part number OH11006 corresponds to a standard adult width layout, historically matching a 16-inch width by 20-inch height (16" x 20")
  • Wing Expansion Dimensions: Because of the curved lateral design, the actual outer fabric shell physical width spans roughly 22 inches at its widest point (the wings), tapering down to fit snug against the narrower back pan structure. 
Powerchair Model Compatibility
This cushion is tailored specifically for Invacare's rehabilitation-level seating systems—most notably the Contoura Seating Framework—and interfaces directly with the following powerbases:
  • Invacare TDX Series (Center-Wheel Drive): Natively fits onto premium configurations of the TDX SP, TDX SP2, and TDX SR models configured with a rigid Contoura backrest shell.
  • Invacare Storm Series: Compatible with the Storm Series Ranger II, Torque SP, and legacy Arrow or Ranger bases utilizing the upgraded adult molded seating packages.
  • Formula Seating Assemblies: Mounts seamlessly to the Formula CG Seating System tilt-and-recline frames that accept standardized slide-on or bolt-on Contoura positioning pads.
