40 year old pillow needs replacing

I have an old down pillow my gramma gave me as a kid. It has no sentimental value. It's just old and squishy, foldable, foldable, pliable as hell. I can fold it under my knees, neck, whereever and it always feels perfect. Its literally falling apart. Holes everywhere, stained. Its nasty. I need a new pillow with this kind of malleable feels like its been worked over for 50 years but is new... any ideas?
