Orthopedic support from this medium firmness coccyx cushion will blow you away with comfort. UNLIKE THE AYILO CUSHION style, this comfort foam seat cushion will not cut off leg circulation as the ergonomic shape provides great support without putting unnecessary pressure on the back of the legs or leaving the base of your spine and tailbone unsupported. Our cushion also has an anti-slip backing to insure your orthopedic seat cushion stays put and doesnt lead to further pain by sliding around. THIS CHAIR SEAT SUPPORT can be a great alternative to the wedge car seat cushion or doughnut as well as being a seat support for office chairs, sitting pillow for kitchen chairs, added comfort for long plane and auto rides, and anywhere you find yourself in a seat all day. AT REFINED ERGONOMICS we take great pride in the quality and design of these black chair cushions! Pads for comfort and pain relief are no laughing matter. This is why we offer a 1 Year Satisfaction Guarantee. If you arent happy and comfortable, we arent either!
