The back cushion does not slip and fulfills its function. The seat cushion does not fit perfectly, so 1 point deduction. It stays in place during use and could be a bit thicker. I've even sewn extra straps and put a cuddly towel underneath and behold it fits and stay where it should be. The processing of the pad is good and the surface can be wiped off well with a damp cloth. I am happy in spite of everything and have also ordered the pad for the second chair of the Great.
