The EmbraceAIR Inline Seat Cushion has a molded natural wood frame and high quality ‘30-year’ foam. The In-Line Seating cradles the buttocks and evenly distributes body weight with contoured leg troughs and overflow edges to 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. Inline 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.
