Sunrise Medical Quickie Manual Wheelchair with Jay J3 Backrest and Whitmyer Headrest

This is a high-specification manual wheelchair featuring a custom specialized seating configuration tailored for complex postural needs. The assembly is built upon what appears to be a Quickie (brand by Sunrise Medical) rigid or folding frame, characterized by its durable black powdered-coated finish and blue cross-bracing accents. A primary feature is the Jay J3 (JAY J3) backrest, a deep-contoured posterior lateral thoracic support shell designed for high-level trunk stability. This is mounted with adjustable hardware and topped with a prominent Whitmyer contoured headrest, which is secured via a multi-axial mounting bracket allowing for precise positional adjustments. The chair is equipped with large rear wheels featuring composite rims and solid tires, alongside push handles with ergonomic rubber grips. Notable features include the integrated handbrakes and anti-tip bars extending from the rear of the frame for user safety. The condition appears to be used but well-maintained, with minor surface scuffs on the plastic components and metal frame consistent with regular indoor and outdoor use. The upholstery on the back and headrest shows no significant tearing or excessive wear. This configuration represents mid-to-late 2010s medical mobility technology, emphasizing modularity and personalized clinical ergonomics.
