It's ok but not great.
As with the Obus Forme Ergonomic Low Back Backrest, the design is good, it stays in place on the car seat, but it just doesn't seem as if the firmness of the cushion is going to last very long. But all in all, I think it's ok for the price. The 2 cushions bought together have a cheaper price which is good.
