The Positioning Platform Chair (PPC) embodies Gunnell, Inc.’s commitment to providing highly customized mobility solutions. Each PPC is meticulously engineered and handcrafted to meet the precise needs of the seating professional and the client, especially those with limited or no flexion. With its capability for anterior tilt, the PPC opens up new possibilities for individuals who might otherwise be confined to bed, allowing them to engage more fully with the world around them. Gunnell’s patented lateral tilt can be added, tilting the platform side to side to fine-tune the patient’s center of gravity.
