Most peacock chair cushions use polyester for the cover (often outdoor/fade-resistant polyester) and polyester or polyester fiber for the fill; some listings note the fill is partially recycled polyester.
Many peacock patio cushions use fade-resistant fabrics and some include moisture- or water-resistant finishes (e.g., a PFAS-free C0 water-resistant treatment). Note that a few styles are not waterproof—manufacturers recommend storing them covered or bringing them indoors in heavy rain.
Common styles include peacock blue/green textured fabrics and reversible peacock/white striped designs. Surface details often include tufting and a cross-weave texture for a classic look.
Peacock chair cushions are frequently sold in multipacks; typical pack sizes in listings are 2, 4, or 6 pieces.
Common sizes include 19" x 19" seat cushions around 5" thick and dining highback options (example: 20" W x 44" H) with a 20" x 20" seat and a 20" x 24" back at about 3.5" thickness.
Most listings use a sewn-seam closure and state the cover is not removable (no zipper). A few styles may have different constructions, but sewn seams are the most common.
Care varies by style: many cushions recommend spot cleaning or wiping with mild soap and water; some covers can be hand washed or machine washed with mild detergent and air-dried or tumble-dried on low. Several listings also advise storing or covering cushions when not in use.
