Our foam back cushion inserts have a zippered hydrophobic liner. They are very durable for many years of use. Our foam back cushions are approximately 5.5" wide due to the added batting around the high-density foam used and will fit snugly, initially, in the back cushion covers. They provide more of a sofa look. For more "squishy-comfortable" back cushions, opt for our poly-fill back cushions in the appropriate size. 

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