I bought the reference for a 40x70 large cervical pillow. The cushion is a little softer than, say, the Tempur pillow. It is not a cheap product but a pad of a factory for the price of 130 bought in stores. But the reference is definitely too small. The ends of the pads are compressed literally, the cushion must be formally filled in the reference. This will of course change the shape and the support characteristics. According to the description of the reference is to fit even for cushions up to the size 50x80. How to fold in a rather soft cushions is a mystery to me.
Quality of the material, processing and color are good.
