The Luxor ergonomic chair cushion delivers supreme comfort and support to help ensure long hours of pain-free work at your desk. Before designing this premium-quality gel seat cushion, Luxor took a good look at common consumer complaints. Among them were insufficient size, flimsy and unsupportive padding, square shapes that cause discomfort and circulation problems in the lower legs, and unpleasant odors common to plastic and rubber. Luxor have addressed these issues with ergonomic contours and a supportive, odor-free TPE gel core. Then they upped the ante with a coccyx cutout, waterfall front to relieve pressure behind the knees, honeycomb cell structure for a cooling airflow, and a breathable and removable mesh cover that's washable.
