I am about to purchase a couple of expensive sofas from Sofas and More. I have a choice of fillings for the seat cushions, Feather Wrapped (foam block surrounded by feathers) or Quallofil Fibre. I like the squishiness of the feather wrapped and am led to believe these will hold their shape. Does anyone have either of these fillings in their cushions and if so I’d really appreciate your thoughts on them. Many thanks
