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 5-7" wide when they relax and considered our standard back cushion, since they are "squishy-comfortable." For more "rigid/sofa-like" back cushions, opt for our foam back cushions in the appropriate size. 

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

**This pair will accommodate a Petite swing/bed with a lower profile, such as the Joshua or Hayden.
