I have two beautiful huge sofas, the flat seat cushions are fine but the back cushions (loose) have scrunched up into a ball inside their covers, and it's like sitting back against balled up clothes. I do plump them but they still sag down and look messy.
I have no idea about this stuff, could I buy replacement cushions for inside? they'd be to fat and firm as the frame of the sofa is bony and unpadded behind the cushions. Should I buy foam squares, or what? Confused!
