Our poly-fill back cushion inserts have a zippered hydrophobic liner. They are very durable for many years of use. Our poly-fill back cushions are approximately 5.5"-9" wide and our standard back cushion, since they are "squishy-comfortable." The taller the back cushion, the fatter they often get when they relax. For more "rigid/sofa-like" back cushions, opt for our foam back cushions in the appropriate size. 

If adding bolsters with back cushions, contact us for customized/shortened bolsters.

**This pair will accommodate a Petite swing/bed with a taller profile, such as the Noah or Aunt Janie.
