With a molded natural wood frame and high quality ‘30-year’ foam, our In-Line Seating cradles the buttocks and evenly distributes body weight. Contoured leg troughs and overflow edges reduce weight on bony prominences. Ideal when your current seat is either too hard, too soft, or when you want to stabilize your back support height. In-Line Seating can be attached to any of our "Embrace" type back supports with the included Velcro straps. Remember, fabric treated to make it immune to fungus bacteria and odor.
