Headrests optimally support and position users with poor head control. Choose a Flat, Contoured or Winged Headrest. The Winged Headrest adjusts from wings almost flat to wings positioned at 90 degrees. All headrests adjust front to back and up and down using Rifton’s unique two-knob adjustment system. Flat and Contoured: 9 x 5 in. (22.9x12.7cm). Winged: 16 x 5 in. (40.6x12.7cm) when flat with 6 in. (15.2 cm) between wings when positioned at 90 degrees.
